Edit Question
Title
Body
I want to select a2.date if it's there, but if it's NULL I want to select a1.date ( a2 is being left-joined). This: SELECT a2.date OR a1.date ... Simply returns a boolean result (as one would expect), how do I get the actual value of the non-null column though? ( a2.date is preferred, but if it's null then a1.date )
