I have a SQL Server 2005. I have two tables. Table1 is the old table and table2 is the updated table. I am trying to update table1 with table2 data but my update code is wrong. What I have in table1 is just Firstname , Lastname, Email, accesslevel. Table2 has the updated First, Last and Email. I just want to update the Firstname, Lastname and Email without loosing the accesslevel in table1. Also the tables have userid's in them also. I was trying to update table1 with table2 data depending on the userid. Here is my code.

SQL

UPDATE [Hot].[dbo].[Table1] SET [Firstname], [Lastname], [Email] = 
Table1.userid
FROM Table2
WHERE [Hot].[dbo].[Table2].userid = Table2.userid

Try this:

SQL

UPDATE table1
SET
    table1.firstname = table2.firstname,
    table1.lastname = table2.lastname,
    table1.email = table2.email
FROM
    table1 JOIN table2
ON
    table1.userid=table2.userid

Peter Leow, Thanks for the code but will this update the right recodes in the table that matches the userid and accesslevel?

yes, for records that have the same userid in both tables. The accesslevel will not be changed.
