MULTI_STATEMENTS - Allow multiple statements - 67108864

Enables support for batched statements. As of 8.0.24, preparing a query with multiple statements raises an error. The direct execution of parameter-less statements prepared using the SQLPrepare() function is not supported. Multiple statements can only be executed through the SQLExecDirec() ODBC function.
