How to query stored procedures in oracle

There are three ways to query Oracle stored procedures: (1) Use SELECT to query the all_procedures table; (2) Use the GET_PROCEDURES function of the DBMS_METADATA package; (3) Use the all_dependencies table to query the dependencies of a stored procedure.

How to query Oracle stored procedures

Direct query

Direct Querying a stored procedure is the quickest way to obtain information about it. Use the following query:

SELECT *
FROM all_procedures
WHERE procedure_name = '<存储过程名称>';

This will return the metadata of the stored procedure, including its parameters, return type, and create statement.

Using the DBMS_METADATA package

The DBMS_METADATA package provides a more advanced way to obtain stored procedure information. Use the following query:

DECLARE
  v_proc_name VARCHAR2(30) := '<存储过程名称>';  -- 替换为实际存储过程名称
BEGIN
  FOR record IN DBMS_METADATA.GET_PROCEDURES(
    ownname  => NULL,  -- 省略所有者名称以检索所有存储过程
    procname => v_proc_name,  -- 指定要检索的存储过程名称
    argnames => NULL,  -- 省略参数名称以检索所有参数
    argtypes => NULL  -- 省略参数类型以检索所有类型
  ) LOOP
    DBMS_OUTPUT.PUT_LINE('存储过程名称： ' || record.procedure_name);
    DBMS_OUTPUT.PUT_LINE('所有者： ' || record.owner);
    DBMS_OUTPUT.PUT_LINE('创建语句： ' || record.text);
  END LOOP;
END;

Query Dependencies

To query the dependencies of a stored procedure, you can use the following query:

SELECT *
FROM all_dependencies
WHERE object_type = 'PROCEDURE'
  AND object_name = '<存储过程名称>';

This will return A list that contains other objects that the stored procedure depends on, such as tables or other stored procedures.
