Stored procedure programs

The 4. With the 5. The 5. What a mouthful! Essentially, MySQL stored programs—procedures, functions, and triggers—comply with the only available open standard for these types of programs—the ANSI standard. Many MySQL and open source aficionados had been hoping for a stored program language implementation based on an open source language such as PHP or Python.

Others anticipated a Java? The MySQL stored program language is a block-structured language like Pascal that includes familiar commands for manipulating variables, implementing conditional execution, performing iterative processing, and handling errors. Programmers familiar with other languages, such as PHP or Java, might consider the language somewhat simplistic, but they will find that it is easy to learn and that it is well matched to the common requirements of database programming.

Security: Stored procedures allow you to enhance the security of an application or a database by restricting the users from direct access to the table.

They are physically stored in the internal, hidden Resource database and logically appear in the sys schema of every system- and user-defined database.

In addition, the msdb database also contains system stored procedures in the dbo schema that are used for scheduling alerts and jobs. SQL Server supports the system procedures that provide an interface from SQL Server to external programs for various maintenance activities.

Extended User-Defined Extended procedures enable creating external routines in a programming language such as C. Extended stored procedures will be removed in a future version of SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible. Create CLR procedures instead. This method provides a more robust and secure alternative to writing extended procedures.
