In case of ROW item each compared pair does not check if argumet collations can be aggregated and thus appropiriate item conversion does not happen. The fix is to add the check and convertion for ROW pairs. mysql-test/r/row.result: test result mysql-test/t/row.test: test case sql/item.cc: added agg_item_set_converter() function which was a part of agg_item_charsets() func. The only difference is that agg_item_set_converter() checks and converts items using already known collation. sql/item.h: added agg_item_set_converter() function sql/item_cmpfunc.cc: In case of ROW item each compared pair does not check if argumet collations can be aggregated and thus appropiriate item conversion does not happen. The fix is to add the check and convertion for ROW pairs.
