Stripping the first three characters off a column

I just accidentally updated my entire database to include 3 characters in front of the product code. I was going to try to do a 'Set' statement utilizing the mid string function to remove the first three characters but Mid is not recognized in Query Analyzer. How can I accomplish this?

Because you said "Query Analyzer," I will assume your database is Microsoft SQL/Server. MID is a Microsoft Access function. Use the SUBSTRING function in SQL/Server.

   update yourTable
      set productcode = substring(productcode,4)

Ordinarily, you will see SUBSTRING expressions with three parameters --

   substring(string, startpos [, length])

When length is omitted, the substring extends to the end of the string.
