Hi SSC,
I've got a table with a clustered index which needs to be dropped and recreated to add an additional column to it. The table also has three non-clustered indices on it. I seem to recall reading somewhere that to do that, I should either drop or disable the non-clustered indices beforehand, but I can't remember exactly why or which one. Can anyone shed some light on the best practice here?

Read about it here. http://technet.microsoft.com/en-us/library/ms190691%28v=sql.105%29.aspx
The section at the top under clustered indexes explains the performance implications of dropping indexes.
