Hi All, I have the following query and I was wondering if spark sql evaluates the same condition twice in the case statement below? I did .explain(true) and all I get is a table scan so not sure if spark sql evaluates the same condition twice? if it does, is there a way to return multiple values where each value belongs to a separate column?
SELECT CASE WHEN <condition 1> THEN <a1> WHEN <condition 2> THEN <a2> ELSE <a3> END AS result1, CASE WHEN <condition 1> THEN <b1> WHEN <condition 2> THEN <b2> ELSE <b3> END AS result2FROM <table> Thanks,
