Detailed Description

Class to hold information about a SQL field.

This is a cut-down version of MYSQL_FIELD, using MySQL++ and generic C++ types instead of the C types it uses, and hiding all fields behind accessors. It leaves out data members we have decided aren't very useful. Given a good argument, we're willing to mirror more of the fields; we just don't want to mirror the underlying structure slavishly for no benefit.

size_t mysqlpp::Field::length ( ) const

Return the creation size of the field.

This is the number of bytes the field can hold, not how much is actually stored in the field on any particular row.
