If what you've got inside the parentheses always is an integer, and it's always the only or first integer in the string, you can use: SELECT (REGEXP_MATCHES(bar, E'(\\d+)'))[1] FROM foo; You can even cast it to an integer on the fly: SELECT (REGEXP_MATCHES(bar, E'(\\d+)'))[1]::INTEGER FROM foo; Or as a more general case, whatever's inside (the first) set of parentheses: SELECT (REGEXP_MATCHES(bar, E'\\((.+?)\\)'))[1] FROM foo; regards, -- Leif Biberg Kristensen http://solumslekt.org/blog/ -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
