Oracle PL/SQL: Stored Procedures & Triggers Guide

To write stored procedures and triggers using PL/SQL in Oracle database, you can follow these steps:

1. Connect to an Oracle database using SQL Developer or another Oracle database management tool.
2. Create a new PL/SQL stored procedure or trigger. In SQL Developer, you can create a new stored procedure or trigger by right-clicking on the “Stored Procedures” or “Triggers” node.
3. Write PL/SQL code. In the editing interface of stored procedures or triggers, write PL/SQL code, including variable declaration, logic control statements, SQL query statements, etc.
4. Compile stored procedures or triggers. Choose the “compile” option in the editing interface to compile stored procedures or triggers to check for any syntax errors in the code.
5. Test stored procedures or triggers. In SQL Developer, you can directly run stored procedures or triggers and observe their execution results.
6. Call stored procedures or triggers wherever necessary. Stored procedures or triggers can be invoked using SQL query statements or other PL/SQL code to achieve the desired functionality.
7. Manage and maintain stored procedures or triggers. In SQL Developer or other database management tools, you can make modifications, deletions, or other management operations on stored procedures or triggers.

By following the above steps, it is possible to write stored procedures and triggers using PL/SQL in Oracle database to implement logic control and data manipulation.
