How to view oracle stored procedures

In Oracle, you can view stored procedures through the following methods: Data dictionary view: Use views such as USER_PROCEDURES to query stored procedure information. PL/SQL Developer: Expand the required stored procedure in the Stored Procedures folder. SQL*Plus: Use the DESC command to view the stored procedure structure.

View Oracle stored procedures

A stored procedure is a set of predefined SQL statements that can be stored and repeated multiple times implement. In Oracle, stored procedures can be viewed in the following ways:

Through the Data Dictionary View

The Data Dictionary view provides metadata information about objects in the database. To view stored procedures, you can use the following views:

• USER_PROCEDURES: Displays stored procedures owned by the current user
• ALL_PROCEDURES: Displays all User's stored procedures
• DBA_PROCEDURES: Displays all stored procedures, including system stored procedures

You can use the following query to view the USER_PROCEDURES view:

<code class="sql">SELECT PROCEDURE_NAME, PROCEDURE_TYPE, LINEAGE
FROM USER_PROCEDURES;</code>

By PL/SQL Developer

PL/SQL Developer is a tool for Oracle database development. Stored procedures can be viewed using PL/SQL Developer by following these steps:

1. Connect to an Oracle database.
2. Under the "Program" node of the Object Browser, expand the "Stored Procedure" folder.
3. Double-click the stored procedure to view.

Through SQL*Plus

SQLPlus is the Oracle command line tool. Stored procedures can be viewed using SQLPlus with the following command:

<code class="sql">DESC <procedure_name>;</code>

For example:

<code class="sql">DESC DELETE_CUSTOMER;</code>

Structure of stored procedures

Syntax of stored procedures As follows:

<code class="sql">CREATE PROCEDURE <procedure_name>
(<parameters>)
[AS]
BEGIN
  -- 存储过程代码
END;</code>

• <procedure_name>: The name of the stored procedure.
• <parameters>: Optional, parameters of the stored procedure.
• BEGIN and END: The beginning and end of the stored procedure code.

Stored procedure code can contain SQL statements, PL/SQL code, and other control flow structures.
