All, Quick question - For a specific scenario I would like to understand below - If we don't specify column header in SQL or alias, how is MonetDB picks up the column header? And what is the datatype for it? I saw it's hge (scalar type) is it so? Also, I would like to know where in source code it's happening. Example: SELECT SUM(COLUMN_NAME) FROM TABLE_NAME; ------------------+ | L3 | ------------------+ |123456678 | ------------------+ Regards, Sreejith
