Statement Type Hint
An Open SQL statement type, RWDBOSql::StatementType, can be NonQuery (the default), Query, or Procedure. This type can be set along with the SQL statement on the constructor or on the statement() method.
 
RWDBOSql::statement(const RWCString& sql, StatementType type=NonQuery)
Although this type setting is not used by all DB Access Modules, it is recommended for application code portability.
