Dumindu Buddhika updated PHOENIX-1705: -------------------------------------- Attachment: PHOENIX-1705_implement_ARRAY_APPEND_built_in_function10.patch Hm, actually the problem I described occurred when calling getMaxLength() on Expressions. But as you mentioned since we need to do the max length check on the variable size data types, I added the condition, !PDataType.isFixedWidth() , so the previous problem does not matter anyway. New patch attached.
