Member Function Documentation

virtual bool I_CursorCmd::Close (  void   )  [protected, pure virtual]

Close the cursor. Return FALSE if the cursor is closed already (or not opened yet) Implemented in CDB_CursorCmd.

virtual bool I_CursorCmd::Delete (  const string &  table_name  )  [protected, pure virtual]

Delete the last fetched row. NOTE: the cursor must be declared for delete in CDB_Connection::Cursor() Implemented in CDB_CursorCmd.

virtual CDB_Result* I_CursorCmd::Open (  void   )  [protected, pure virtual]

Open the cursor. Return NULL if cursor resulted in no data. Throw exception on error. Implemented in CDB_CursorCmd.

virtual int I_CursorCmd::RowCount (  void   )  const [protected, pure virtual]

Get the number of fetched rows Special case: negative on error or if there is no way that this command could ever affect any rows (like PRINT). Implemented in CDB_CursorCmd.

virtual CDB_SendDataCmd* I_CursorCmd::SendDataCmd (  unsigned int  item_num, size_t  size, bool  log_it = true )  [protected, pure virtual]

Implemented in CDB_CursorCmd.

virtual bool I_CursorCmd::Update (  const string &  table_name, const string &  upd_query )  [protected, pure virtual]

Update the last fetched row. NOTE: the cursor must be declared for update in CDB_Connection::Cursor() Implemented in CDB_CursorCmd.

virtual bool I_CursorCmd::UpdateTextImage (  unsigned int  item_num, CDB_Stream &  data, bool  log_it = true )  [protected, pure virtual]

Implemented in CDB_CursorCmd.
