Question

I have three fields and if column three equals a certain value, I want to get the value of column 2. Can I do this in a SELECT, and would I use an IF or CASE statement?

Answer 1

A CASE statement would be the easiest way to do this. The following SQL compares two columns. You can alter this to use WHEN Col2 = 'xxxx' THEN xxxx'.

SELECT Col1, Col2, CASE
                   WHEN Col2 = Col1 THEN 'True'
                   ELSE 'False'
                   END AS 'Columns Match'
  FROM Table
