Transact-SQL in an internationally standardised method to create, modify and delete databases and tables, as well as insert, retrieve, modify and delete data stored in a database. With Microsoft SQL Server 2005 you can also author procedures in any managed language such as C# or VB. This is because it is integrated with the CLR which allows you write powerful programs inside stored procedures. All functionality of the .NET Framework BCL (Base Class Library) is available to your stored procedures. This means that developers have access to thousands of pre-built classes and routines which can be accessed. The BCL includes classes that provide functionality for improved string functioning, advanced math operations, file access, cryptography, and more.
local procedure wont store in database. Stored procedure store in database permanently and we can use it whenever we require. Other program also can use this stored procedure. And the transaction of stored procedure take care by DBA. But the local procedure transaction is take care by manually only
An SQL database is one that implements the use of Structured Query Language to manage data stored in the database. SQL is the most used way of communicating with databases.

A procedure is a specified series of actions, acts or operations which have to be executed in the same manner in order to always obtain the same result under the same circumstances A stored procedure is a subroutine available to applications accessing a relational database system. Stored procedures (sometimes called a proc, sproc, StoPro, or SP) are actually stored in the database data dictionary. In a procedure you have to start the transaction manually, allowing the rollback manually and stuff like that. In a stored procedure, usually the DBA system takes care of the main transaction in case of errors. You can even use atomic transactions to keep your information consistent. Then, A stored procedure is execute a bit faster than a single procedure because of the indexing in the dba.
SQL is a mostly standard language that allows for analysis and presentation of data stored in a database. The INNER JOIN command is one of the basic SQL commands. SQL training will teach you how to use this command, as well as the commands that result in other types of joins, like outer joins, left outer joins, etc. The best SQL training sources will present you with a simple set of raw data and examples of the result sets generated from each type of query. Be aware that there are several similar versions of SQL that vary with each target database (SQL Server, DB2, etc.) so be sure that the training you sign up for is specific to the database that you intend to use.
SQL*PLUS is a interface between user and Oracle database. It Provide an environment to use the SQL which is a query language to communicate with oracle database
SQL is the language used to access a database. So if you want to work with databases, especially to query or manipulate data, then it is important that you learn SQL. Even if you use other APIs, you will still need to use SQL queries.
You can go to the SQL Course website and there you will be able to practive what you learn and also be able to receive immediate results from submitting your SQL commands. EVen if you have your SQL there is the option to practice SQL statements and use the website as a refresher
yes definitely you need to update
