Passing string parameters to linked Oracle Server procedures from SQL Server

Question

I have an Oracle procedure called P_CREATE_USER. It takes a single varchar2 parameter:

create or replace PROCEDURE 
P_CREATE_USER (P_US         


        

Answer 1

The solution required checking the Dynamic Parameters property in the OraOLEDB.Oracle driver in SQL Server (Server Objects/Linked Servers/Providers/OraOLEDB.Oracle).

Then, to call the procedure, I had to do the following:

DECLARE @userid varchar(50)
SET @userid = 'MyUserId'
EXECUTE ('BEGIN P_CREATE_USER(?); END;', @userid) AT ORACLE_SERVER
