## Detailed Description

StoreQueryResult set type for "use" queries.

See the user manual for the reason you might want to use this even though its interface is less friendly than StoreQueryResult's.

## Member Function Documentation

Row mysqlpp::UseQueryResult::fetch_row | ( |  | ) | const

Returns the next row in a "use" query's result set.

This is a thick wrapper around DBDriver::fetch_row(). It does a lot of error checking before returning the Row object containing the row data.

See also:
  fetch_raw_row()

void mysqlpp::UseQueryResult::field_seek | ( | Fields::size_type | field | ) | const`[inline]`

Jumps to the given field within the result set.

Calling this allows you to reset the default field index used by fetch_field().

mysqlpp::UseQueryResult::operator MYSQL_RES * | ( |  | ) | const`[inline]`

Return the pointer to the underlying MySQL C API result set object.
