when you start coding any DB2 pgms you should include SQLCA
and DCLGEN member in w-s section and perform activities of
coding which need to be processed in procedure division.
all statements should be scoped in EXEC SQL and END-EXEC
scope
only and you should precompile, create package and plan, you
should run this pgm by using plan. these are the steps we
follow these days.

SET is the ANSI standard for variable assignment, SELECT is not. SET can only assign one variable at a time, SELECT can make multiple assignments at once. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one) When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value) As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
