Release 10.1A: OpenEdge Development:
Progress Dynamics Advanced Development

> ## Other query properties

> Other useful query properties include:

> - `DataHandle` — This property returns the handle to an SDO’s temp-table query. You can use this property to modify a query and reopen it.

> - `RowObject` and `RowObjUpd` — These `HANDLE` properties hold the buffer handles of the `RowObject` and `RowObjUpd` buffers, respectively.

> - `RowObjectTable` and `RowObjUpdTable` — These `HANDLE` properties hold the handles of the RowObject and RowObjUpd temp-tables.

> - `AutoCommit` — This `LOGICAL` property is set automatically, depending on whether there is a Commit button or other object in a window that acts as a `Commit-Source` for an SDO. If there is, then the property is set to `FALSE`. If there is no `Commit-Source`, then it is set to `TRUE`. When it is `TRUE`, any `Save` to an SDO record is sent immediately to the server for validation and update. When it is `FALSE`, then saves are stored only locally in the client temp-table until the `Commit` event occurs. At that time all updates are sent back to the server together.

> Note: Autocommit triggered by one SDO’s update always applies to all unsaved changes in an SBO.
