Postgresql query to update fields using a regular expression

Question

I have the following data in my \"Street_Address_1\" column:

123 Main Street

Using Postgresql, how would I write a query to update t

Answer 1

Something like...:

UPDATE table
SET Street_Name = substring(Street_Address_1 FROM '^[0-9]+ ([a-zAZ]+) ')

See relevant section from PGSQL 8.3.7 docs, the substring form is detailed shortly after the start of the section.
