Question

I know I can use the SQL below to query a list of stored procedures in Oracle:

SELECT * FROM USER_PROCEDURES
ORDER BY OBJECT_NAME

But how can I retrieve a list of arguments I needed to pass in for a particular stored proc?

Answer 1

The system view all_arguments will give you this information, but bear in mind that it will yield no rows if the procedure in question has no parameters:

SELECT argument_name, data_type, in_out, position
FROM all_arguments
WHERE object_name = 'MY_PROC'
AND owner = USER
AND data_level = 0
ORDER BY position;
