Hi all,

As shown below, despite CREATE TABLE WITH DATA works fine, CREATE TEMPORARY TABLE WITH DATA is not able to create a temp table with data.

Is this a bug? or something I misunderstand? Are you using auto commit? Then the temporary table is probably emptied at the end of your transacion. SQL standard's default for temporary tables defines an commit action 'DELETE ROWS', where you probably want 'ON COMMIT PRESERVE ROWS'
