from the select list and TEXT field make setup_copy_fields to insert Item_copy_string for blobs in the beginning of the copy_funcs (push_back instead of push_front) the thing is that Item_copy_string::copy for function can call Item_copy_string::val_int for blob via Item_ref. But if Item_copy_string::copy for blob isn't called before, it's value will be wrong. So all the Item_copy_string::copy for blobs should be called before Item_copy_string::copy for functions. mysql-test/r/having.result: added test case for Bug #4358 Problem with HAVING clause that uses alias from the select list and TEXT field mysql-test/t/having.test: added test case for Bug #4358 Problem with HAVING clause that uses alias from the select list and TEXT field sql/sql_select.cc: make setup_copy_fields to insert Item_copy_string for blobs in the beginning of the copy_funcs (push_back instead of push_front) the thing is that Item_copy_string::copy for function can call Item_copy_string::val_int for blob via Item_ref.
