如何用相同的编号编写程序 ＆SQL Server中的参数设置？

Question

SQL Server stored procedure:

CREATE PROC proc1
AS
SELECT ename FROM employee

Oracle Server stored procedure:

CREATE OR REPLACE PROCEDURE proc1
(
cv_1 IN OUT SYS_REFCURSOR
)
AS
BEGIN
OPEN cv_1 FOR
SELECT ename
FROM employee ;
END;

Is it possible to write this procedure in both Oracle & SQL Server with same number of parameter with same supported data type?

If possible how? and so how to call from both oracle & SQL Server?

Answer 1

We do this all the time and it works great however our systems are based on ODBC using the ODBC "Call" syntax to invoke procedures. I believe this feature was added to the Oracle driver circa Oracle 10.

For example:

{CALL proc1} or if proc1 has non ref cursor parameters {CALL proc1(parm1,parm2,parm3)}

Oracle driver automatically does what is necessary to convert ref cursor(s) into result set(s). I believe there is/was an ordering dependancy in that the cursor parameter(s) need to be positioned last after any normal input parameters other than that you can have the same code returning result sets (using exact same query string to call procedures between SQL Server and Oracle)
