I have been reading about contidional expresions in a query and I have a question about the following example included in the documentation:
SELECT a, CASE WHEN a=1 THEN 'one' WHEN a=2 THEN 'two' ELSE 'other' END FROM test;
I would like to make a few changes but I need to give a name (an alias) to the result of the CASE. Can an "AS" be added as shown below?
SELECT a, b, CASE WHEN a=b THEN a ELSE a || '-' || b END AS ab FROM test;
Respectfully,
Jorge Maldonado
