Query a stored procedure for it's parameter names and types

Question

Is there any easy way to query a stored procedure (Oracle - PL/SQL) for what parameters it expects?

I know that I can query USER_SOURCE to get the whole procedure but I'd then have to parse the whole procedure, and if the parameter is of type [table].[column]%TYPE I'd then have to query the table schema as well.

Either using just sql or via ODP.Net.

Answer 1

The USER_ARGUMENTS view will give you the details.

Answer 2

Another method is to call DBMS_DESCRIBE.DESCRIBE_PROCEDURE.
