Cannot create temp tables

Not a corporate problem this but irritating nevertheless. I have SQL 4.13.UDI running on SCO UNIX 3.2 and as the creator of a database, I'm unable to execute the "CREATE TEMP TABLE table (table_id INTEGER); " statement. The error I get is 261: Cannot create file for table (USER.table) 1: Not owner As USER I get this even if I just create a dummy database. Since I have a single user system, I have made sure that /tmp and all directories where a temp table might be placed have 777 permissions and there is planty of space. If su to informix, I can create the hich then exists in /tmp. I can of course create normal tables. Can anyone throw light on what I need to do? I'd be grateful -- Nigel Booty
