Hi

I try To add the columns D + E + F and display the result in column C
I run this update query to do it.

UPDATE Table_Name
SET C = isnull([D],0) + isnull([E],0) + isnull([F],0)
Where = 'GWC'

I get that little * as result, Any idea?

[b] A B C D E F
ABCDEF GWC * 553 371 0
GHIJKL GWC * 381 375 0
MNOPQR GWC * 358 482 0
STUVWX GWC * 14 70 0

Thanks!

You are probably right, because my table is a temporary one.
Should I convert the data fisrt before the addtion then?

can you post the structure of your table? you need to make sure C is of integer type if D,E,F are all integer

My table is a temporary table and doesn't have any structure.
To make sure the data types are okay, then I should create the temporary table and specify the type, right?

UPDATE #Table_Name
SET C = isnull([D],0) + isnull([E],0) + isnull([F],0)
Where = 'GWC'

C int,
D int,
E int,
F int,
....
)

Give the man a cigar!
Do you know if in SQL 2005 we also need to do the same?

Thanks for your help!

See why you get *

declare @d varchar(3)
set @d=123*600
print @d
