Currently, I have the following code in SQL script runs in sqlplus:

DEFINE REGION         = &&1
EXECUTE MY_PROC


I like to add IF THEN condition.  Please remember this is not pl/sql.  How to do?  Thanks.

DEFINE REGION         = &&1

IF REGION ='USA' THEN
EXECUTE MY_PROC
END IF

If it was a function you could use some thing like

select decode('&&REGION','USA',MY_FUNC) from dual;

You could probably create a wrapper function that will call your stored proc and then use the above select statement

create or replace my_func returns number
is
begin
my_proc;
return null;
end;
/

Then use
select decode('&REGION','USA',MY_FUNC) from dual;

It is simple. you don't need to any wrapper function or extra step. sql*plus wil be enough for you to do it.

actonwang :  I tried the following and returns EXEC MY_PROC as value, it don't EXECUTE MY_PROC.  

SELECT 'EXEC MY_PROC' FROM DUAL WHERE 1=1;


MohanKNair :  I don't want to use BEGIN and END in the SQL

I found a solution.  I change the MY_PROC to accept in parameter value and use if/then checking the REGION value then run like the following:

EXECUTE MY_PROCE(REGION)

you'd have to use my whoe script, not just that ONE sql query:

///////////////
DEFINE REGION=&&1

set feedback off echo off verify off

SPOOL  exec.sql

SELECT 'EXEC MY_PROC'
FROM DUAL
WHERE '&REGION' = 'USA';

SPOOL OFF

ewang1205,

sql*plus is not procedural and it is better to code if..then..else clauses within pl/sql.
