While living in the world of piles of papers, it was very difficult to remember every bit of information and managing its massive volume too, such that, it could be retrieved and processed, easily and as soon as possible, whenever required.

For example, if you needed to find a specific file, say a file on a business proposal made some time ago with an ABC Company, you would have checked every single file manually till you got the right data. A very time consuming and resource wasting operation!

But today, in digital era, we have systems that can collect and organize data/information on your behalf.

Database system is one such system which organizes and manages multiple types of data/ information – such as employee records, payroll, accounting, inventory etc. for different business and organizations and SQL is the language which is used to communicate with the databases.

What is SQL?

Structured Query Language (SQL) is a programming language which uses a set of commands to manipulate the data in databases. It helps users to retrieve that data which they are looking for. Also, SQL helps to insert, modify data in existing database tables and even delete data from SQL database tables.

What is a stored procedure?

Stored procedure is a set of SQL statements (with an assigned name) that’s stored in the database in a compiled form so that it can be shared by a number of programs in order to perform a specific task.

Why to use Stored Procedure?

  1. It improves productivity and performance as statements in a stored procedure only need to be written one time. You can re-use same SQL code multiple times. So instead of writing the same SQL statement repetitively, just call the stored procedure.
  2. It helps in controlling data access as end-users can insert or modify data but cannot not write procedures.
  3. It helps in preserving data integrity as information is entered in a consistent manner.
  4. It reduces network traffic between the server and client as commands in a procedure are executed as a single batch of code and only the call which executes the procedure is sent across the network.
  5. It provides an added layer of security as it limits direct access to tables. It grants permission to EXECUTE the stored procedure instead of giving permission on tables. Thus, helps prevent hacking directly into the database tables.
  6. It supports multiple languages and multiple platforms for different client applications. Each application uses same procedures and the user just have to embed a standard procedure call for the language in the program.
  7. It helps in processing bulk of data speedily i.e. promotes set based processing.
  8. MySQL provides you with a suite of tools for developing and managing critical business applications on Windows. All ZNetLive customers can use MySQL stored procedure and routines on their Linux as well as windows web hosting accounts.
