What is Indexing: Additional auxiliary access structure is called indexes, a data technique to efficiently retrieve records from the database files based on some attributes on which the indexing has been done. Dense Index: 1)In dense index, there is an entry in the index file for every search key value in the main file. This makes searching faster but requires more space to store index records itself. 2)Note that it is not for every record, it is for every search key value. Sometime number of records in the main file is greater than = number of search keys in the main file, for example if search key is repeated. Sparse Index: 1)If an index entry is created only for some records of the main file, then it is called sparse index. 2)No. of index entries in the index file is less than No. of records in the main file.

How to Code Oracle Analytic Functions
 
52:40
Many more free Oracle Database and SQL tutorials at http://skillbuilders.com/free-oracle-tutorials. SQL is a language that allows you to perform queries to answer a wide range of questions about your data. While standard SQL is quite powerful, there are many questions that it cannot answer at all or that it can only answer with complex and inefficient SQL workarounds. Questions about running totals, percent of total, and ranking within a group fall into this area. Also, more complex issues such as Top-N within a group and aggregates over a range also fall in this arena. These questions can be easily answered via a new class of SQL statements called Analytic Functions. This presentation will show you how to use Oracle's Analytic Function extensions to SQL to answer these questions simply and efficiently.

Should I Learn Oracle or SQL Server?
 
02:17
Should I learn Oracle or SQL Server? While Oracle DBA certification pays well, the classes and getting a practice version of Oracle is expensive. I heard you could get versions of SQL Server for free. Part of it depends on the software developers you're working with. Use SQL Server if you're working with Microsoft's .Net, whereas Java developers are more likely to use Oracle. I didn't know that SQL Server was a Microsoft brand. So if you'll be working on MS servers and MS databases, you need to learn the SQL server. Which one is better for my career? There are typically more MS SQL jobs, but the Oracle jobs pay more. Oracle doesn't have as many jobs, but you have less competition. Those who didn't join the Microsoft cult pay a price for it. Which one is harder to learn? Oracle is rather complex, whereas MS SQL Server is simpler because it has a good graphical user interface. It's nice to hear that Microsoft made at least one good user interface. They usually put out crap, but once in a while, there's a good one. I've heard MySQL is more popular. Only because of the so called popularity of Microsoft. Oracle is the heavyweight database tool. Which relational database is better? MySQL works with almost any web-based application. Oracle is more stable, secure and scalable for enterprise wide applications. I'm glad to know that the big data that is running the world isn't all beholden to Bill Gates. No, but most PCs that generate the data still are. It sounds like I need to learn Oracle. Fortunately, you can learn Oracle inside and out and a little MS SQL and do almost any database admin job you'd like. You're guaranteed to get dates if you can proudly announce you have stable, well paying employment. It's like saying you're a musician, artist and athlete at once. Girls will just be happy if she doesn't have to pay for the date these days.

Analytical Functions in oracle explained with real examples
 
25:24
This video explains analytical functions and how they are implemented in real projects. Analytical functions are somewhat similar to aggregate functions,but they offer much more. Why use analytical function ? They allow you to write fast and concise queries which otherwise will involve self join and long processing times They allow you to perform aggregate functions independently on sets of partitions. You can access values from previous rows in current row and you can restrict the window on which you want to apply this analytical function. I have given additional practice exercises along with the dataset so that you can comfortably work with analytical functions. You can find the sample problems along with dataset in the below link. http://www.internshipsfromhome.com/oracle-analytical-functions-ddl-and-dml/

Oracle Database11g tutorials 13 || SQL substr function / SQL substring function
 
06:34
link of SQL substr blog : http://www.rebellionrider.com/SQL-substr-function.htm SQL substr function SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. Tool used in this tutorial is command prompt. This tutorial series is part of SQL expert exam certification training. if you are preparing for SQL certification you can use my tutorials. This SQL Tutorial is a part of free training.

Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

Oracle SQL Tutorial 11 - CREATE TABLE
 
05:04
The way you create a table is to use the CREATE TABLE command. CREATE TABLE users() So in this situation, the name comes right after the TABLE keyword. The next thing we do is put all of the columns on a line that we want to put in our table. CREATE TABLE users( user_id, username, first_name, last_name ) Notice the naming conventions here. For this series we are going to make columns with what is known as snake casing. This is where each individual word is separated by an underscore. if you have more than one column, all of them have to have commas except the last one. The comma is a way to say that another column is coming, so you don't need to do it on the last one. Now you would think we were done, but we also have to say what data type each column is. Later we will extensively discuss data types so we can focus on them exclusively. For now, here are the data types we are going to use: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50), first_name VARCHAR2(50), last_name VARCHAR2(50) ) Now, inside of the parenthesis for varchar2, we pass in a number... This is the max length of the string. But the question is, what is it measured in? The default is actually in bytes, not characters. For example if we have the string hello, it is 5 characters, but it might take up a total of 10 bytes of storage. So I would recommend adding the keyword char right after the number so it defaults to 50 characters, not bytes. CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR), first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) This will work to create a table, but it's really missing a lot of information… which column is the primary key? Are we adding any indexes? Is there any thing else we need to say about these columns? So as you can tell, we are making progress, but there is still so much to learn. The biggest gotcha to remember from this video is that the data type VARCHAR ends in a 2, stupid, right? who would end the name of something with a 2? Once again, this is Caleb from CalebTheVideoMaker2, and we will catch you in the next one! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Oracle SQL Tutorial 32 - VARCHAR2 and NVARCHAR2
 
03:06
This video we are going to discuss the VARCHAR2 and the NVARCHAR2 data types. The previous videos are a good foundation to this video. I've actually discussed so much stuff in those videos that I don’t have a whole lot to say. Good for you, right? I discussed over the previous videos that you should prefer to use VARCHAR2 over CHAR. That's because there is not a difference in performance or storage for a VARCHAR2 column. The only difference is that an CHAR column forces each value to take up a certain length even if it's not. There is one difference between the variable length and fixed length data types here that you need to know about, and that is storage limits. CHAR has a limit of 2000 bytes, while VARCHAR2 has a limit of 4000 bytes. That means you can store twice as much junk in a VARCHAR2 column! Other than that, these data types work exactly the same. I recommend you always use the VARCHAR2 data types instead of the CHAR data types, and only use NVARCHAR2 if you have a non-Unicode database. This will allow you to store Unicode characters in a column. Now, the amount of storage you can put in a VARCHAR2 column is twice what you can put in a CHAR column, but 4000 characters is still not very many characters. This is where the LOB data types come in, which we will discuss in the next video! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

jQuery datatables get data from database table

There are many ways to get data into DataTables. If the data is small you can retrieve all the data at once and the processing (i.e paging, searching, ordering) is done on the client-side. On the other hand if the database data is large, server-side processing can be enabled. With server-side processing enabled, all paging, searching, ordering actions that DataTables performs are handed off to the server. In this video we will discuss retrieving all the data at once. The datatables plugin performs all the processing (i.e paging, searching, ordering etc) on the client-side. We want to retrieve data from the following database table tblEmployee. The database data should then be displayed using jQuery datatables plugin

Simplifying Effective Date Range Queries with Temporal Validity with Chris Saxton and Stew Ashton
 
01:00:22
Storing changes to data over time is a common requirement. For example, many businesses like to keep a historic record of customer address changes or product price updates. Data warehouse developers frequently need to store history in slowly changing dimensions. Typically these requirements are implemented by adding effective "from" and "to" date columns to tables. This requires developers to write convoluted select statements to find the rows active at a given point in time. This is error-prone and open to interpretation by developers, making applications harder to maintain. Introduced in 12c, temporal validity provides a standard way to write queries using effective date ranges. Implementing this helps improve developer productivity by simplifying SQL and providing a consistent method for managing time series data. Watch this session to see how you can easily adopt this on your 12c databases.
