Thread: Select Non Alpha Contents of a Column
Is there a way to select all rows where a certain column starts with non-alpha characters? I would like to select all the rows that don't start with letters. Possible? Hunter

Regular expressions would do what you want, e.g. "select * from mytable where myfield !~ '^[a-zA-Z]';" Look under "pattern matching" in the "functions and operators" section of the manual (I think, working from memory). __________________________________ Do you Yahoo!?
