Updating Values with UPDATE Statements in SQL Server

Q

How To Update Values in a Table with UPDATE Statements in SQL Server?

✍: FYIcenter.com

A

If you want to update some values in one row or multiple rows in a table, you can use the UPDATE statement. The tutorial script below shows a good example:

SELECT * FROM fyi_links WHERE id = 101
GO
id      url                     notes   counts  created
101     dev.fyicenter.com       NULL    0       2006-04-30

UPDATE fyi_links SET counts = 999, notes = 'Good.' 
   WHERE id = 101;
GO
(1 row(s) affected)

SELECT * FROM fyi_links WHERE id = 101
GO
id      url                     notes   counts  created
101     dev.fyicenter.com       Good.   999     2006-04-30

As you can see, the SET clause takes column and value pairs to provide new values, while the WHERE clause defines which row to apply the update.
