I have a field of type character varying. On insert I'd like to strip out special characters. In this particular case I'd like to strip out hyphens from a column of hyphenated strings, hyphen_field"123-456-789" from table_two and insert as "123456789" into non_hyphen_field in table_one. I'm starting with a statement of the following form:
INSERT INTO schema.table_one(var_one,var_two,non_hyphen_field)
SELECT var_one, var_two, hyphen_field
FROM schema.table_two;
What is the cleanest way to accomplish this?
