want to select max number over 4 columns

Hello

I have a data set from my query as per the following
Company    Value1     Value2     Value3     Value4
A                    5                 2              0              0
B                    0                  12           0             45
C                    0                  0             0              0
D                   12                 1             88           4  etc etc

What I want is to include another column which gives me the max value in each row - or - just return the max value per row for each customer - eg
Company    Max
A                    5          
B                   45
C                    0      
D                   88

Regards

No problem.

Whenever you have a few minutes, it's always worth the time to just scan the SQL docs from time to time.

Just scanning the available functions can make you click on them to see what they do.  You will learn a lot...
