Why is using \'*\' to build a view bad ?
Suppose that you have a complex join and all fields may be used somewhere.
Then you just have to chose fields needed
Once upon a time, I created a view against a table in another database (on the same server) with
Select * From dbname..tablename
Then one day, a column was added to the targetted table. The view started returning totally incorrect results until it was redeployed.
Totally incorrect : no rows.
This was on Sql Server 2000.
I speculate that this is because of syscolumns values that the view had captured, even though I used *.
