Disadvantages of Procedures
- Stored procedures can cause a lot of memory usage. The database administrator should decide an upper bound as to how many stored procedures are feasible for a particular application.
- MySQL does not provide the functionality of debugging the stored procedures.
Procedures in PL/SQL
A Procedure in PL/SQL is a subprogram containing a series of declarative SQL statements that can take parameters and be called to perform a specific action.
These PL/SQL procedures are stored in the database catalog. A procedure can be thought of as a function or a method. They can be invoked through triggers, other procedures, or applications on Java, PHP, etc.
All the statements of a block are passed to the Oracle engine all at once which increases processing speed and decreases the traffic.
Here, we will learn about Procedures in PL/SQL with examples and learn how to create, modify, and delete procedures. It is a very important concept of database and you might face several PL/SQL Procedure interview questions during the job hunt, so understand the concept carefully.
