SELECT with a Replace()
- by andyjohnson
I have a table of names and addresses, which includes a postcode column. I want to strip the spaces from the postcodes and select any that match a particular pattern. I'm trying this (simplified a bit) in T-SQL on SQL Server 2005:
SELECT Replace(Postcode, ' ', '') AS P
FROM Contacts
WHERE P LIKE 'NW101%'
But I get the following error;
Msg 207, Level 16, State 1, Line 3
Invalid column name 'P'.
If I remove the WHERE clause I get a list of postcodes without spaces, which is what I want to search. How should I approach this? What am I doing wrong?
