ILIKE is probably better - without an escape:
WHERE field1 ILIKE field2 ESCAPE '' You could also try: WHERE upper(field1) = upper(field2) David J. From: pgsql-general-ow...@postgresql.org [mailto:pgsql-general-ow...@postgresql.org] On Behalf Of Allan Kamau Sent: Wednesday, November 21, 2012 4:39 AM To: Postgres General Postgres General Subject: [GENERAL] Escaping regexp special characters in field value I do have a field for which I want to perform a join with some other field in another table using case without case sensitivity perhaps using ~*. One of this fields may contain + characters or unbalanced parenthesis. Is there a way or some function that may mask out the regexp awareness of any of these characters if they appear the field values. Should I need to write a function to escape each of these characters by placing a "\" character before it? Allan.
