Hello
I want to use max() function and I want to read the input of this function from another database(its name is exhibitor). like below :

select @LastDate=MAX([exhibitor.dbo.Maintable.LastUpdate])



but I have error below

Msg 207, Level 16, State 1, Procedure Exec_List, Line 131
Invalid column name 'exhibitor.dbo.Maintable.LastUpdate'.

Because you referenced a column without a FROM clause.

select @LastDate=MAX([LastUpdate]) FROM exhibitor.dbo.Maintable.

I'd also like to recommend that you avoid 3 part naming in code. Create a synonym for the table in the other database and then stick to 2 part naming. That way, if you even move or rename the database or the table, you won't have to find all of the places it was used in code. All you'll need to do is change the synonym.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink
