How to get the list of parameters of the supplied Stored procedure in oracle 11g

Question

我需要在oracle 11g中进行查询，以获取给定存储过程的所有参数，其数据类型和其模式（输入或输出）的列表。

Answer 1

You can take a look at ALL_ARGUMENTS or USER_ARGUMENTS Tables.

SELECT ARGUMENT_NAME,DATA_TYPE,IN_OUT 
FROM USER_ARGUMENTS WHERE OBJECT_NAME = UPPER('ProcedureName');

Answer 2

If you would like to get a view about the parameters of the procedure, just use

 SQL> desc <procedure name>;

If you would like to see the code for the procedure, then use (assuming you are logged in as the owner of the procedure)

 SQL> SELECT Text FROM User_Source WHERE Name ='PROCEDURENAME' ORDER BY Line;

Answer 3

try the following query

 select * from user_source where type = 'PROCEDURE'

This will give you all the stored procedures stored in your schema. Alternatively, you can also define type as Function or Packages to get required information.
