• Direct call:Use theEXECUTEstatement to directly call the stored procedure.
• Via PL/SQL:Call the stored procedure using theCALLstatement in PL/SQL code.
• Via JDBC:Using JDBCCallableStatementExecute the stored procedure.

Advantages of Stored Procedures

The main advantages of using stored procedures include:

• Code Reusability:Stored procedures can be easily reused in multiple applications.
• Performance improvement:Reduced interaction with the database server, thereby improving performance.
• Data Integrity:Helps ensure data accuracy and consistency.
• Security:Provides a security mechanism to protect sensitive information.
