Re: CREATE TABLE how to avoid empty table

David wrote:
I just realised CREATE TABLE AS ( select....) WITH DATA
creates an empty table when no records are selected.
I don't want the table if there are no records.
So now I'm having to create the table separately,
execute an INSERT INTO and monitor for SQL0100.

Is there a way of avoiding the creation of an empty table?


David -
I'm assuming this is in an RPG program.

One way is to use a Common Table Expression to perform the select statement
beforehand and get a record count of the selected records *before* running
the CREATE TABLE SQL statement, then if the record count is > 0, run the
CREATE TABLE.

Example:

With CTE as
(Select field1, field2, field3 from Table1 where field1 = '1' and field2 =
'2' )
Select count(*) from CTE into :reccount

If reccount > 0;

do your create table here...

endif;
