I want to thank everyone in advance for your assistance in this matter. I'm running MS SQL 2k. In a database called consumer there is a table called consumerdata. In the telephone column there are phone numbers, but at times some fields are null and some just contain a zero 0. I'm trying to replace the rows that contain only a 0 with nothing, but I don't want to effect a row of data that happens to contain a zero such as 9544801001 as that has to be left untouched. And ideas for a t-sql script? Also I should mention there are 160 million rows :(

Thanks everyone... Sal

UPDATE ConsumerData
SET PhoneNumber = NULL
WHERE PhoneNumber = '0'
