Oracle DECODE Function
 
04:31
https://www.databasestar.com/oracle-decode-function/ The Oracle DECODE function lets you perform IF-THEN-ELSE functionality in your queries. It’s similar to a CASE statement. The syntax of the DECODE function is: DECODE ( expression, search, result [, search, result]... [,default] ) The parameters of the Oracle DECODE function are: - expression (mandatory): This is the value to compare. - search (mandatory): This is the value to compare against the expression. - result (mandatory): This is the return value if the search value matches the expression value. There can be multiple combinations of search and result values, and the result value is attached to the previous search value. - default (optional): If none of the search values match, then this value is returned. If this is not provided, the DECODE function will return NULL if no matches are found. If you compare this to an IF-THEN-ELSE statement, it would look like this: IF (expression = search) THEN result [ELSE IF (expression = search) THEN result] ELSE default END IF The parameters can be one of many different data types, and the return type is calculated from them. Earlier I mentioned it’s similar to CASE. So why would you use one and not the other? - DECODE is an older function, and CASE was introduced as a replacement for DECODE. - CASE offers more flexibility then DECODE - CASE is also easier to read and debug (in my opinion) The performance of these functions is the same, so if you’re considering using DECODE, I would suggest using CASE instead. For more information about the Oracle DECODE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-decode-function/

What is Parameterized Cursor in Oracle
 
03:39
What is Parameterized Cursor in Oracle. In simple words a cursor with parameter is called parameterized cursor. PL/SQL allows developer to pass parameters into cursors. Same as like we can pass parameter into function and procedure. PL/SQL Parameterized cursor pass the parameters into a cursor and use them in to query. Cursor becomes more reusable using Cursor parameters. PL/SQL Parameterized cursor define only data type of parameter and not need to define it's length. In Parameterized cursor scope of the parameters are local within program only. Optionally, we can also give a default value for the parameter, which will take effect if no value is passed to the cursor. Key point 1. Scope of the parameters are locally 2. You can assign default value to a cursor parameter. 3. Cursor becomes more reusable with Cursor parameters. 4.PL/SQL Parameterized cursor define only data type of parameter and not need to define it's length.

Oracle CURRENT_TIMESTAMP Function
 
02:37
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_TIMESTAMP function will display the current date and time in the session time zone. Just like the CURRENT_DATE function, it uses the session time zone, which is where you logged in from. This could be different to the database time zone. The syntax of the CURRENT_TIMESTAMP function is: CURRENT_TIMESTAMP ( [precision] ) The return type of this function is TIMESTAMP WITH TIME ZONE. The precision parameter is optional, and it lets you specify the number of fractional seconds to return. If this is omitted, it uses the default of 6. It’s different to the SYSTIMESTAMP function, because CURRENT_TIMESTAMP returns the session timezone, and SYSTIMESTAMP returns the database time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_TIMESTAMP will return a date and time that’s 10 hours ahead of SYSTIMESTAMP, and in a different time zone. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_TIMESTAMP - 7 for 7 days ago). However, it might be better to use interval data types so you can keep the original data type. For more information about the Oracle CURRENT_TIMESTAMP function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-date-functions/

Oracle DECOMPOSE Function
 
01:41
The Oracle DECOMPOSE function is used to transform a string into a Unicode string. It will split a character that has an accent, for example, into two characters. It’s the opposite of the COMPOSE function. The syntax of the DECOMPOSE function is: DECOMPOSE ( input_string [CANONICAL|COMPATIBILITY] ) The parameters of this function are: - input_string is the string that will be decomposed into separate character values in a string. It can be any character data type. - CANONICAL|COMPATIBILITY is an optional parameter and allows you to specify the mode of decomposition. CANONICAL is the default. CANONICAL means it can be re-composed with the COMPOSE function. COMPATIBILITY means that it can’t be re-composed, but it can be useful for katakana characters.

Oracle TO_DATE Function Explained with Examples
 
06:14
https://www.databasestar.com/oracle-to_date/ The Oracle TO_DATE function is one of the most useful conversion functions in Oracle. It can be a little confusing though. The TO_DATE function is used to convert a character value to a date value. You can use it to convert a string that is in the format of a date, into a date data type. Why would you use this? Converting a character to a date is helpful if you want to insert a date into a column in a table. Being specific about the format (explicit) is better than assuming the conversion will be done for you (implicit). This TO_DATE function only converts to a DATE data type. If you want to convert to the other datetime data types, you’ll have to use other functions such as TO_TIMESTAMP or TO_TIMESTAMP_TZ. The syntax for this function is: TO_DATE(charvalue [, format_mask [, nls_date_language]]) The parameters for this function are: Charvalue: This is the character value that you want to convert to a date. It’s the main input of the function. Format_mask: This is the format that the input value, the charvalue, is in. This is used to help convert your character value into a date, as your character may be in a different format to the default. Nls_date_language: this is used to determine how the output is displayed. For more information about the Oracle TO_DATE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-to_date/

Oracle TO_TIMESTAMP Function
 
01:31
https://www.databasestar.com/oracle-to_timestamp/ The Oracle TO_TIMESTAMP function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP value. A TIMESTAMP value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, seconds, and fractional seconds This is a useful data type because it allows you to store a time down to fractions of a second. The syntax of the TO_TIMESTAMP function is: TO_TIMESTAMP ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names. The default format will depend on the region you’re running your database in. In my example (using Oracle Express in Australia), the default format is ‘DD-MM-RRRR HH:MI:SS AM’. For more information on the Oracle TO_TIMESTAMP function, including the SQL used in this video, read the related article here: https://www.databasestar.com/oracle-to_timestamp/

Oracle TO_CHAR Function
 
04:13
https://www.databasestar.com/oracle-to_char/ The Oracle TO_CHAR function is a common and useful string manipulation function. It allows you to convert a number or a date value into a string value. It allows you to take a number or a string, and convert it to a VARCHAR2 data type. The syntax of the function is: TO_CHAR( input_value, [format_mask], [nls_parameter] ) The parameters are: - input_value: this is the value to convert to a VARCHAR2 value. It can be one of many different number or date data types. - format_mask is an optional parameter and allows you to specify the format to display the output as. If this is omitted, the function uses a default format. - nls_parameter: this is also optional and lets you determine a regional parameter for displaying the output value. The format mask helps you determine what your output is displayed as. For example, if you provide the date of May 3rd, and the output is ‘03/05/2018’, how do you know if this is May 3rd or March 5th? Using a format mask can specify which format is used. The function is similar to the TO_NUMBER and TO_DATE functions, in that they both convert a specific data type. For more information about the Oracle TO_CHAR function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-to_char/

Oracle LISTAGG Function
 
04:57
https://www.databasestar.com/oracle-listagg/ The Oracle LISTAGG function allows you to aggregate or combine string values from multiple rows into a single row. For example, it turns this data: FIRST_NAME Adam Brad Carrie Into this data: FIRST_NAME Adam, Brad, Carrie The same data is shown, but it’s in one row and not multiple. It’s a valuable string manipulation function, and once you know what it is and how it works, you’ll be able to use it in your queries as needed. So what does it look like? The function is: LISTAGG ( measure_expr [, delimiter]) WITHIN GROUP (order_by_clause) [OVER query_partition_clause] These parameters are: measure_expr: This is a column or expression that you want to concatenate the values of. In the example above, it was the first_name column. Mandatory. delimiter: This is the character between each of the measure_expr values. Optional, the default is a comma. order_by_clause: This is the order that the values from the measure_expr are listed. Mandatory. query_partition_clause: This allows you to use LISTAGG as an analytic function, allowing you to show LISTAGG in groups for different rows. One thing to be aware of is that the output of the Oracle LISTAGG function is limited to 4,000 bytes. If you get more than this, you’ll receive an error. The most common way around this that I’ve seen is to write a custom function and use a CLOB. Watch the video to find out more and see some examples. For more information about the Oracle LISTAGG function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-listagg/

Oracle CURRENT_DATE Function
 
01:54
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_DATE function is used to return the current date in the session timezone. The session timezone is the timezone that the current user is logging in from. This can be different from the database’s timezone. The syntax of the CURRENT_DATE function is: CURRENT_DATE No parameters are needed - just the function name. The function returns a DATE data type, and it includes hours, minutes, and seconds. This is good to know because the default display format for DATE does not include the time component, and it can be easy to forget. It’s different to the SYSDATE function as SYSDATE returns the date in the database timezone, and CURRENT_DATE returns the date in the session time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_DATE will return a date and time that’s 10 hours ahead of SYSDATE. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_DATE - 7 for 7 days ago).

Oracle LPAD Function
 
04:27
https://www.databasestar.com/oracle-lpad/ The Oracle LPAD function is used to add extra characters to the left of a text value. This is called “padding”, and the function is called LPAD because the L stands for “left” and it “left pads” a text value. It’s the opposite of RPAD, which pads characters to the right of the value. The LPAD function can be useful for ensuring all values are the same length, or if there is another requirement you have for adding characters to the end. The syntax is: LPAD(expr, length [,pad_expression]) The expr parameter is the text value you want to pad or add characters to. The length is the total length the expression or value will be after the padding has been done. It’s not the number of characters to add. The pad_expression is an optional field and is the character or characters to add to the left end of the string. The default value is a space. If the length specified in the function is shorter than the length of the string, then the string is truncated to meet the length.

Java default method
 
12:43
In this tutorial we will discuss default methods in Java Interfaces. With Java 8, Oracle introduced several new features like functional programming, lambda expressions etc. There was need to extend already existing interfaces like List and Collection. However, one could not simply add new methods to Java interfaces as most of the existing implementations would break. Hence, default methods were introduced for backward compatibility. Here we learn about the benefits of default methods in Java, and what rules are applicable on them when such interfaces are extended or implemented. Here is the code used in tutorial - public modifier indicates that interface can be used in any other interface or class. default modifier is package public interface ITimeService { void printTime(int hour, int minute, int seconds); void printDate(int day, int month, int year); } public class SimpleTimeService implements ITimeService { @Override public void printTime(int hour, int minute, int seconds) { System.out.println("Time =] " + hour + ":" + minute + ":" + seconds); } @Override public void printDate(int day, int month, int year) { System.out.println("Date =] " + day + "/" + month + "/" + year); } } public class Program { public static void main(String[] args) { ITimeService timeService = new SimpleTimeService(); timeService.printTime(12, 30, 10); timeService.printDate(10, 10, 2017); } } default void printDateTime(int hour, int minute, int seconds, int day, int month, int year) { System.out.println("DateTime =] " + day + "/" + month + "/" + year + " " + hour + ":" + minute + ":" + seconds); } public class AnotherTimeService implements ITimeService { @Override public void printTime(int hour, int minute, int seconds) { System.out.println("Time =] " + hour + "-" + minute + "-" + seconds); } @Override public void printDate(int day, int month, int year) { System.out.println("Date =] " + day + "-" + month + "-" + year); } @Override public void printDateTime(int hour, int minute, int seconds, int day, int month, int year) { System.out.println("DateTime =] " + day + "-" + month + "-" + year + " " + hour + "-" + minute + "-" + seconds); } } ITimeService timeService = new SimpleTimeService(); timeService.printTime(12, 30, 10); timeService.printDate(10, 10, 2017); timeService.printDateTime(12, 30, 10, 10, 10, 2017); ITimeService anotherTimeService = new AnotherTimeService(); anotherTimeService.printTime(12, 30, 10); anotherTimeService.printDate(10, 10, 2017); anotherTimeService.printDateTime(12, 30, 10, 10, 10, 2017);

Oracle LENGTH Function
 
01:23
https://www.databasestar.com/oracle-length/ The Oracle LENGTH function allows you to find the length of a string, also known as the number of characters in a string. It’s a common feature in different languages, and SQL is no different. The LENGTH function only has one parameter: LENGTH ( string_value ) The parameter is the string_value which is the value to check the length of. The function returns a number that represents the number of characters in the function. Some points to remember about the Oracle LENGTH function: If string_value is NULL, then LENGTH will return NULL. If string_value is an empty string, the LENGTH will return NULL. The string_value can be any of the character data types - CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, NCLOB. If the string_value is a CHAR data type, then the LENGTH will include any trailing spaces in the value. For more information about the Oracle LENGTH function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-length/

Oracle INSTR Function
 
03:28
https://www.databasestar.com/oracle-instr/ The Oracle INSTR function allows you to search a string for the occurrence of another string, and return the position of the occurrence within a string. It’s helpful for finding if a string exists within another string. It can also be used for performing further string manipulation on, like substrings. The syntax of the INSTR function is: INSTR(string, substring [, start_position [, occurrence]]) These parameters are: string: The text string that is searched in. It’s usually the larger of the two strings. Mandatory. substring: The text to search for. It’s usually the smaller of the two strings. Mandatory. start_position: This is an integer value which indicates where in the string value to start the search. Optional, and the default is 1. occurrence: The occurrence of the substring to search for. Optional, and the default is 1, which means the first occurrence. Also, the searches performed by the INSTR function are case-sensitive. The value returned by INSTR is a number value, which is the number in the location of the string where the substring is found. The first character is 1.

PL/SQL:NVL/NVL2/Coalesce function
 
05:26
In this tutorial, you'll learn the difference between NVL,NVL2 &Coalesce functions PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Oracle RPAD Function
 
04:22
https://www.databasestar.com/oracle-lpad/ The Oracle RPAD function is used to add extra characters to the right of a text value. This is called “padding”, and the function is called RPAD because the R stands for “right” and it “right pads” a text value. It’s the opposite of LPAD, which pads characters to the left of the value. The RPAD function can be useful for ensuring all values are the same length, or if there is another requirement you have for adding characters to the end. The syntax is: RPAD(expr, length [,pad_expression]) The expr parameter is the text value you want to pad or add characters to. The length is the total length the expression or value will be after the padding has been done. It’s not the number of characters to add. The pad_expression is an optional field and is the character or characters to add to the right end of the string. The default value is a space. If the length specified in the function is shorter than the length of the string, then the string is truncated to meet the length. For more information about the Oracle RPAD (and LPAD) function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-lpad/
