http://www.sqltrainingonline.com SQL Null or Empty - How to Check for Null or Empty Column in SQL Server - SQL Training Online You can download the sample table script at http://www.sqltrainingonline.com/how-to-filter-for-sql-null-or-empty-string/. In this video, I show you how to filter for a SQL null or empty string. It can be difficult to filter a null because you can't simply compare with an equal sign. You have to use a special IS NULL clause to make the filter work. I also show you how to combine both the SQL Null and Empty String together in a special trick with the isnull SQL Server function. I use SQL Server 2012 to demonstrate the technique.

SQL Server 30 - How to INSERT Data
 
05:48
Now that we have our tables created, we need to learn how to actually put data into our tables. That is where the INSERT command comes in. The basic syntax looks like: INSERT INTO TableName VALUES(data…); Data is where we put a value for each column. Strings are single quoted, numbers are left blank with no quotes. Just like when we create tables we try to create the parent tables first, we do the same with inserting data. We always want to insert the parent rows first. So let's add a species to our table. As a reminder, this is what our CREATE TABLE looks like: CREATE TABLE Species( ID INT PRIMARY KEY IDENTITY, Species VARCHAR(50) NOT NULL UNIQUE, FriendlyName VARCHAR(50) NOT NULL ); Now to insert data: INSERT INTO Species VALUES('Pentalagus P. furnessi', 'Bunny'); Now you can see that there may a violation of everything being atomic because we are actually storing the genus and species of this animal in one column. But…YOLO. Now we can view this data by finding the table in the object explorer, right clicking, and selecting Edit Top 200 Rows. Notice that the IDENTITY column is automatically filled. Now, this is a great time to show you some stuff regarding foreign keys. The first thing I want to show you is how they protect our data integrity. Let's insert some data in the Animals table and try to reference an invalid species. Once again, here is what our table creation looks like: CREATE TABLE Animals( ID INT PRIMARY KEY IDENTITY, Name VARCHAR(50) NOT NULL, Species INT NOT NULL REFERENCES Species(ID), ContactEmail VARCHAR(50) NOT NULL UNIQUE ); INSERT INTO Animals VALUES('Sally', 2, '[email protected]'); SQL Server does not let us insert this data. The second thing I wanted to show you is that the name of the constraint that is in violation is being shown here. That is why naming your constraints can come in handy so when this happens you can find it much easier. Last thing is that if you want to INSERT multiple rows, throw a comma after the VALUES, and put another parenthesis with more data: INSERT INTO Animals VALUES('Sally', 1', '[email protected]'), ('Franklin', 1, '[email protected]') ; Maybe someday we will get around to adding a row to our species table for turtles, but for now we are going to make Franklin a bunny. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 10 - Whitespace, Case Sensitivity, and Comments
 
07:48
SELECT "Hello World" FROM DUAL The first thing you should know about writing queries is that this SQL is not whitespace sensitive. That means we can space this out however we wish. The only requirement is that you do not separate keywords out with spaces. They must be as one entity. Another gotcha is that when you are inside of quotes, whitespace becomes very important. That means if inside of a string you put a character and then 10 spaces, every single one of those spaces is going to part of that string: SELECT "Hello World" FROM DUAL The next thing you should notice is the capitalization. When we type SQL, by convention we capitalize all keywords. I personally really like this because you can easily see the difference between keywords and words that we created or use. But obviously we could capitalize the letters in the quotes. Keep in mind that this is a convention, meaning you do not have to follow this. Oracle is also case insensitive in that SELECT and select both do the same thing. Strings, once again, care about casing. Take this, for example: SELECT 'true' FROM DUALWHERE 'Hello' = 'Hello' And compare the results to this: SELECT 'true' FROM DUALWHERE 'Hello' = 'hello' Only the first one outputs the value true. Once we get into creating database objects such as tables with columns, those are not case sensitive either. That means instead of selecting from DUAL, you can select from DuAl Finally, I shall introduce you to comments. Comments allow you to tell the database engine that you want it to ignore a certain part of your code and not execute it. This is helpful if you want to document your code. It is also useful if you want to have multiple SQL statements open in one tab, but don't want to hover over the one you want to execute. You can comment out the ones you are not using and uncomment them when you are done. Using – will comment out the rest of the line, Using /* */ will comment everything between. This can even be used over multiple lines. But now, let's move onto the important stuff… CREATING TABLES!!!!! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ HELP ME! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

We have already discussed the intro of SQL character function in Video 10. You can find link of this video in description below. Ok let's go ahead. SQL Concat () function concatenates two separate character string into one character string. Let's see the syntax Concat (string_1 , String_2) Note here that SQL Concat function takes only two arguments at a time. This SQL Concat function will return string_1 concatenated with string_2. This also means that it will return a single string which is a combined string of parameter String_1 and String_2. Both the parameters of SQL Concat function String_1 and string_2 can be of any data-type. You can even specify the columns of the table here. SQL Concat function is equivalent to the concatenation operator (||). SQL concatenation operator is represented by double solid vertical bars or we can say double pipe signs. Question: How to concatenate more than two strings as SQL Concat that can have only 2 parameters and what is the difference between SQL Concat Function and SQL concatenation operator? The one answer for the second Question What is the Difference between SQL Concat Function and SQL concatenation operator? Is While SQL Concat function takes only two parameters, The Concat operator can be repeated as often as is necessary. Meaning, by the help of SQL Concat operator you can combine as many strings as you want. And Concatenation operator is also not supported by several databases such as SQL server so this might cause problem. To answer the first question How to concatenate more than two strings as SQL Concat that can have only 2 parameters? We will have to jump over SQL developer. Let's see some examples. Say we want to retrieve the full name of an employee from Employees table. Let's try it using SQL Concat function. SELECT Concat (first_name, last_name) AS "Full Name" FROM employees; Here in this query we use two column names - first_name and last_name as arguments of our Concat function Execute. As you can see here, we get full name of our employee but there is no space in between first name and last name. We will see how to format this string using SQL Concat function in a few seconds But before that, let's see how to do the same task using SQL concatenation operator. SELECT first_name ||last_name AS "Full name" FROM employees; As you can see this query also produces the same result. Now we will see how to format full name of employees First we will do this using SQL concatenation Operator. SELECT first_name||' '||last_name AS "Full name" FROM employees; Now you can see we get space between first name and last name of the employee. Again, let's do it using SQL Concat function. Here we will see the nested function concept where we will be using nested Concat function to achieve this formatted string. SELECT Concat (Concat (first_name, ' '), last_name) FROM employees; Inner Concat function has two parameters. These are our first column name first_name and an empty string which will be a space between first name and second name. This Concat will now return a string which is the first name with space. This returning string will be the first input of our Outer Concat and column last_name will be the second input. All together this will give us the desired output. As you can see this method is complex than the first one where we use SQL concatenation operator.

SQL Tutorial 7: CONCAT function, ORDER BY, NULL value
 
09:21
How do you concatenate or combine columns and place it on a derived column? How do you check if a column contains NULL value? How do your arrange rows or records in descending or ascending order? The video presents sample problems with solution as you work with a SELECT statement. CONCAT () function combines data among columns. It is not limited with two columns but may work with multiple columns as you combine it with another CONCAT function. Use two double-pipe symbols (||) instead if you opt not to use CONCAT function. Not all columns are filled up or has values on it in a given table. When a column contains no data even a single space, it has a NULL value. In using DB2 command line, a NULL column is represented by a single dash. When generating a SELECT statement output it has no general sorting order on its result. To specify the correct sorting order, use ORDER BY clause after FROM. Ascending is the default order when sorting a particular column. If you want to sort in descending order, use DESC. Sort order is not limited with one column. You may combine with multiple columns by specifying which column to sort first followed by the next column order to sort. CONCAT, ORDER BY, and NULL are universal in all dbms SQL products. It is the same if you use MS SQL Server, MySQl, Informix, Oracle, and DB2. Link for the ebook will be announced later.

07 MySQL Tutorial for Beginners: Logical Operators (AND, OR, NOT), NULL, IS NULL Clause
 
09:39
"Logical operators" enable us to use more than one condition in WHERE clause. You use the AND "logical operator" to specify that the search must satisfy both of the conditions. In other words: both conditions must be true. You can use "logical operators" in a WHERE clause to combine two or more search conditions into a compound condition. You use the OR "logical operator" to specify that the search must satisfy at least one of the conditions. In other words: only one of the conditions must be true. You can use the NOT "logical operator" to negate a search condition. The order of precedence for the logical operators affects the result of a search condition. When MySQL evaluates a compound condition, it evaluates FIRST the AND operator and THEN the OR operator. You can use parentheses to override the order of precedence. If you want, you can use parentheses to clarify the sequence in which the operations are evaluated even if they're not needed for the expression to be evaluated properly, just as you can with arithmetic expressions. A column can contain a NULL value. A NULL value is typically used to indicate that a value is not known, unavailable, or not applicable. A NULL value is not the same as a zero or an empty string. If you want to test for NULL values in search conditions, you have to use the IS NULL clause instead of the normal comparison operators. A NULL value is not the same as a zero and as an empty string. The row that has a NULL value isn't included in the result set when numbers is NOT equal to zero as well. You can also use the NOT operator with the IS NULL clause.

Dynamic SQL in Stored Procedure
 
09:32
In this video we will discuss, using dynamic sql in a stored procedure and it's implications from sql injection perspective. We will discuss performance implications of using dynamic sql in a stored procedure in a later video. Text version of the video http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure.html Slides http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure_11.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All SQL Server Tutorial Videos https://www.youtube.com/playlist?list=PL08903FB7ACA1C2FB All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists Consider the following stored procedure "spSearchEmployees". We implemented this procedure in Part 139 of SQL Server tutorial. This stored procedure does not have any dynamic sql in it. It is all static sql and is immune to sql injection. Create Procedure spSearchEmployees @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Select * from Employees where (FirstName = @FirstName OR @FirstName IS NULL) AND (LastName = @LastName OR @LastName IS NULL) AND (Gender = @Gender OR @Gender IS NULL) AND (Salary = @Salary OR @Salary IS NULL) End Go Whether you are creating your dynamic sql queries in a client application like ASP.NET web application or in a stored procedure, you should never ever concatenate user input values. Instead you should be using parameters. Notice in the following example, we are creating dynamic sql queries by concatenating parameter values, instead of using parameterized queries. This stored procedure is prone to SQL injection. Let's prove this by creating a "Search Page" that calls this procedure. Create Procedure spSearchEmployeesBadDynamicSQL @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from Employees where 1 = 1' if(@FirstName is not null) Set @sql = @sql + ' and FirstName=''' + @FirstName + '''' if(@LastName is not null) Set @sql = @sql + ' and LastName=''' + @LastName + '''' if(@Gender is not null) Set @sql = @sql + ' and Gender=''' + @Gender + '''' if(@Salary is not null) Set @sql = @sql + ' and Salary=''' + @Salary + '''' Execute sp_executesql @sql End Go Add a Web Page to the project that we have been working with in our previous video. Name it "DynamicSQLInStoredProcedure.aspx". Copy and paste the HTML and code available on my blog at the following link http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure.html At this point, run the application and type the following text in the "Firsname" text and click "Search" button. Notice "SalesDB" database is dropped. Our application is prone to SQL injection as we have implemented dynamic sql in our stored procedure by concatenating strings instead of using parameters. ' Drop database SalesDB -- In the following stored procedure we have implemented dynamic sql by using parameters, so this is not prone to sql injecttion. This is an example for good dynamic sql implementation. Create Procedure spSearchEmployeesGoodDynamicSQL @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Declare @sql nvarchar(max) Declare @sqlParams nvarchar(max) Set @sql = 'Select * from Employees where 1 = 1' if(@FirstName is not null) Set @sql = @sql + ' and [email protected]' if(@LastName is not null) Set @sql = @sql + ' and [email protected]' if(@Gender is not null) Set @sql = @sql + ' and [email protected]' if(@Salary is not null) Set @sql = @sql + ' and [email protected]' Execute sp_executesql @sql, N'@FN nvarchar(50), @LN nvarchar(50), @Gen nvarchar(50), @sal int', @[email protected], @[email protected], @[email protected], @[email protected] End Go On the code-behind page, use stored procedure spSearchEmployeesGoodDynamicSQL instead of spSearchEmployeesBadDynamicSQL. We do not have to change any other code. At this point run the application one more time and type the following text in the "Firstname" textbox and click the "Search" button. ' Drop database SalesDB -- Notice "SalesDB" database is not dropped, So in this case our application is not succeptible to SQL injection attack. Summary : Whether you are creating dynamic sql in a client application (like a web application) or in a stored procedure always use parameters instead of concatnating strings. Using parameters to create dynamic sql statements prevents sql injection.

How to Resolve Oracle SQL Parent Key Not Found (ORA-02291)
 
05:49
In this video, we’ll explain what the ORA-02291 “parent key not found” error is, see an example, and look at how to resolve it. This error usually happens when we try to insert data into a table. It looks like this: Error is: ORA-02291: integrity constraint (constraint_name) violated - parent key not found So what does this error mean? It means we’re trying to insert data into a child table, and there is no related record in the parent table.

IS NULL Operator in SQL Query with Example
 
02:24
SQL IS NULL Operator: A column value is NULL if it does not exist. The IS NULL operator is used to display all the rows for columns that do not have a value. For Example: If you want to find the emp names who do not get any commision, the query would be as given below: select * from emp where COMM IS NULL; In the opposite way, NOT NULL also works here: select * from emp where COMM IS NOT NULL; Thanks for watching..:)

Introduce Oracle enhanced adapter for ActiveRecord - RubyKaigi 2014
 
31:48
Talker: Yasuo Honda http://rubykaigi.org/2014/presentation/S-YasuoHonda Oracle Enhanced Adapter is one of the 3rd party ActiveRecord database adapters. It supports Rails from 2.3 to 4.1. It has been developing well since version 1.5.0 was released on the day same day Rails 4.0.1 was out, November 1st 2013. Now we are on the way to support Rails 4.2. In Rails world MySQL and PostgreSQL are two giant databases, Oracle database does not have much presense here. Although it has better features such as good optimizers it also has some non-standard features like handling empty string as NULL. However, this situation has been changing. Finally Oracle 12c implements row limits and offset then developers can write better Top-N queries without dirty subquery and rownum statements. I'll introduce a experimental Arel implementations without ugly order_hacks method. I have been working for Oracle enhanced adapter since August 2011, starting from Rails 4 support. It is still the first 3 years. Fortunately I'm still enjoying to do that, yes I'm not burned out yet. I'm sorry that I have nothing to do with your license fee but we can keep contributing source code to resolve your technical issues. I'd be glad to hear that anyone start using Oracle database and Oracle enhanced adapter with your Rails applications. Oracle Enhanced Adapterは、ActiveRecord 3rd partyデータベースアダプタです。Rails 2.3から4.1に対応しており、Rails 4への対応も4.0.1がリリースされた2013年11月1日と同日から対応するなど、着実なサポートが継続されており、現在はRails 4.2の対応が進んでいます。 ご存じの通り、Railsの世界ではMySQLとPostgreSQLのふたつのデータベースが大きなシェアをもっており、Oracleの利用報告はごくわずかです。優れたオプティマイザなどの機能を持つ反面、NULLと空文字を同様に扱うなど、"標準"とはことなる独自の実装がなされてきましたが、近年では他データベースでの便利な機能やSQL標準の対応もされるようになりました。なかでも、Oracle 12cでは、row limits、offsetの対応が追加され、ようやくまともなTop-N queryが書けるようになりました。これにより、悩ましいArelでのorder_hacksが削除されたシンプルなArel実装を紹介します。 私は2011年の8月からOracle enhanced adapterのRails4対応から、まだ最初の3年間ではありますが、燃え尽きることなくやってくることができました。 ライセンス費用は私にはどうすることもできませんが、Railsで利用するための技術的な課題が解決されることで、OracleをRailsのデータベースとして採用するきっかけとなれば幸いです。

String Functions in SQL Server part-IV || REPLACE, REPLICATE, REVERSE, RIGHT, RTRIM functions in SQL
 
03:57
This video will provide you the details of each string functions in SQL Server 2014. I'll be walking through each and every kinds of build in function which are available in SQL Server in my next videos. Previous video for more String Functions String Function Part I https://www.youtube.com/watch?v=6cgn44DZ7w8 String Function Part II https://www.youtube.com/watch?v=RmyT87mstzc String Function Part III https://www.youtube.com/watch?v=lQVnQKeGlf0 ***************************************************************************************** REPLACE (Transact-SQL) Replaces all occurrences of a specified string value with another string value.  Syntax REPLACE ( string_expression , string_pattern , string_replacement )  Arguments string_expression Is the string expression to be searched. string_expression can be of a character or binary data type. string_pattern Is the substring to be found. string_pattern can be of a character or binary data type. string_pattern cannot be an empty string (''), and must not exceed the maximum number of bytes that fits on a page. string_replacement Is the replacement string. string_replacement can be of a character or binary data type.  Return Types Returns nvarchar if one of the input arguments is of the nvarchar data type; otherwise, REPLACE returns varchar. Returns NULL if any one of the arguments is NULL. If string_expression is not of type varchar(max) or nvarchar(max),REPLACE truncates the return value at 8,000 bytes. To return values greater than 8,000 bytes, string_expression must be explicitly cast to a large-value data type. ***************************************************************************************** REPLICATE (Transact-SQL) Repeats a string value a specified number of times.  Syntax REPLICATE ( string_expression ,integer_expression )  Arguments string_expression Is an expression of a character string or binary data type. string_expression can be either character or binary data. Note : If string_expression is not of type varchar(max) or nvarchar(max), REPLICATE truncates the return value at 8,000 bytes. To return values greater than 8,000 bytes, string_expression must be explicitly cast to the appropriate large-value data type. integer_expression Is an expression of any integer type, including bigint. If integer_expression is negative, NULL is returned.  Return Types Returns the same type as string_expression. ***************************************************************************************** REVERSE (Transact-SQL) Returns the reverse order of a string value.  Syntax REVERSE ( string_expression )  Arguments string_expression string_expression is an expression of a string or binary data type. string_expression can be a constant, variable, or column of either character or binary data.  Return Types varchar or nvarchar ***************************************************************************************** RIGHT (Transact-SQL) Returns the right part of a character string with the specified number of characters.  Syntax RIGHT ( character_expression , integer_expression )  Arguments character_expression Is an expression of character or binary data. character_expression can be a constant, variable, or column. character_expression can be of any data type, except text or ntext, that can be implicitly converted to varchar or nvarchar. Otherwise, use the CAST function to explicitly convertcharacter_expression. integer_expression Is a positive integer that specifies how many characters of character_expression will be returned. If integer_expression is negative, an error is returned. Ifinteger_expression is type bigint and contains a large value, character_expression must be of a large data type such as varchar(max).  Return Types Returns varchar when character_expression is a non-Unicode character data type. Returns nvarchar when character_expression is a Unicode character data type. ***************************************************************************************** RTRIM (Transact-SQL) Returns a character string after truncating all trailing blanks.  Syntax RTRIM ( character_expression )  Arguments character_expression Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data. character_expression must be of a data type that is implicitly convertible to varchar. Otherwise, use CAST to explicitly convert character_expression.  Return Types varchar or nvarchar

MySQL 25 - CHAR Data Type
 
04:47
The first category of data types that we are going to cover in this MySQL series are the string data types, or character data types. There are two that I am going to talk about in this video, CHAR and VARCHAR. We'll start with CHAR. CHAR is a string data type where you specify how many characters are allowed in parenthesis after you declare the column as this type. For example, we can say CHAR(50) to allow up to 50 characters for each value in that column. The thing to know about CHAR though is that it is a fixed-length string. That means every single value inside of that column is actually going to be whatever you declare the length as. So if you say CHAR(50), every string is going to be 50 characters long. If, for example, you have a row that only uses 40 characters, MySQL will pad the right side of the string with spaces until it fills 50 characters. Now, the highest value you can put in here is 255. The 255 refers to characters. This means that you can have strings with up to 255 characters. How does the computer know how to store these characters? That has to deal with the character set and the encoding of the characters. By default, MySQL is going to use UTF-8. We are not going to discuss UTF-8 in detail for a while but essentially UTF-8 says that each character can take up to 3 bytes of storage. 255 comes from the max number you can count to using binary. So if we are keeping track of how many values are in this column in an 8 bit number, 255 is the highest. If you don't know what I'm talking about it, we'll worry about it later. You can actually make the column CHAR(0). In this situation, the only thing you could put in as a value for this column is an empty string (''). When retrieving variable length CHAR data from a database it may not look like the database pads the value. That's because MySQL actually strips spaces from the value when presented. If you want to keep all of the spaces that have been added when you retrieve the value, you can do that. Look up PAD_CHAR_TO_FULL_LENGTH online. In the next video we are going to discuss VARCHAR. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)
