Thread: CREATE TABLE AS does not support IF NOT EXISTS?
This works:
CREATE TEMP TABLE temp_medical_summary AS (SELECT * from bov.medical_summary)
This gives an error:
CREATE TEMP TABLE IF NOT EXISTS temp_medical_summary AS (SELECT * from bov.medical_summary)
It would seem that CREATE TABLE AS does not support IF NOT EXISTS. Is this true?

FYI the Postgres version would be helpful, as syntax support changes over versions:) In any case the most recent production version docs show IF NOT EXISTS is not supported: http://www.postgresql.org/docs/9.1/interactive/sql-createtableas.html > > David Waddy -- Adrian Klaver adrian.klaver@gmail.com
Thank-you, mystery solved! I was reading the "CREATE TABLE" docs and not the "CREATE TABLE AS" docs. My mistake.

In any case the most recent production version docs show IF NOT EXISTS is not
supported:
