//--First reason is when initializing this, original mariadb seems only send in 19 values,
//this means SqlDataType will always be 0 in resultset, it's against ODBC API and MySQL practice.
//--Second is to treat 5 columns that defined as smallint but will accpet null as result.
//--Third is reuse SqlDataType1 as USER_DATA_TYPE
