Detailed Description
Base class for StoreQueryResult and UseQueryResult.
Not useful directly. Just contains common functionality for its subclasses.
Member Function Documentation
◆ field_num()
| int mysqlpp::ResultBase::field_num | ( | const std::string & | i | ) | const |
Get the index of the named field.
This is the inverse of field_name().
References names_, and mysqlpp::OptionalExceptions::throw_exceptions().

Default field index used by fetch_field()
It's mutable because it's just internal housekeeping: it's changed by fetch_field(void), but it doesn't change the "value" of the result. See mutability justification for UseQueryResult::result_: this field provides functionality we used to get through result_, so it's relevant here, too.
