Thread: Create an empty copy of another table
Hi, How do I create a new empty table that`s a copy of an allready existing one? I need a way of putting the result of a select-statement into a temporary table that`s an exact copy of the table it`s derived from and I`m not sure how to do this. Obviously. I am just using one table to query at the time. Thomas

I don't have time to test it out right now, but it should be something like this: SELECT * INTO tblTemp FROM tblExistingTable WHERE nFieldOne = 5; Look in the docs under SELECT INTO David Boerwinkle -----Original Message----- From: Thomas Weholt <Thomas@cintra.no> To: 'pgsql-novice@postgresql.org' <pgsql-novice@postgresql.org> Date: Wednesday, June 28, 2000 9:29 AM Subject: [NOVICE] Create an empty copy of another table >Hi, > >How do I create a new empty table that`s a copy of an allready existing one? >I need a way of putting the result of a select-statement into a temporary >table that`s an exact copy of the table it`s derived from and I`m not sure >how to do this.
