Hi, In my table, I have fieldA and fieldB. At any point in time, only one of these fields can have data in it. The other is NULL.
Instead of "select fieldA, fieldB from table", I want it to return either fieldA or fieldB depends on whether it is NULL or not. The reason is because I want to use "select array_to_string(array_accum(field A or field B) ,',') from table. Is it possible to do it that way? Thanks, JB
