Question

Sample Table : MyTable1

Col1    |    Col2     |     Col3
   3           10            5
  10           9             40
   1           2             6

The Output must be:

NewColumn
    10
    40
     6

As you can see, I just need to get the highest value from each row..

Is it possible by just using a sql select query?

Thanks in advance

Answer 1

You will need to use the MS Access function IIF()

IIF(condition, valueiftrue, valueiffalse)

condition is the value that you want to test.

valueiftrue is the value that is returned if condition evaluates to
TRUE.

valueiffalse is the value that is returned if condition evaluates to
FALSE.

so your query would be

SELECT IIf(C12 > Col3, C12, Col3) as newColumn
FROM
(
    select IIF(Col1 > Col2,  Col1,  Col2) as C12, Col3
    from mytable1
) x
