RDbView Class Reference
| class RDbView : public RDbRowSet |
Generates rowsets from an SQL query. The query is prepared and evaluated using the interface to this class, while the rowset is manipulated using the RDbRowset base class.
There are no special rules to consider when deriving from this class.

EvaluateAll()
| IMPORT_C TInt | EvaluateAll | ( | ) | |
Prepare(RDbDatabase &, const TDbQuery &, TAccess)
Prepares the view object for evaluating an SQL select-statement.
Following preparation, the rowset object can always provide schema information, but the view may first require evaluation to generate the rowset for navigation.
-
capability
- Note For a secure shared database, the caller must satisfy the read access policy for the table.
Parameters
| RDbDatabase & aDatabase | The database on which to execute the query. |
| const TDbQuery & aQuery | The SQL query and the text comparison mode for the constraint. |
| TAccess anAccess = EUpdatable | The access specification for the rowset. By default, updatable access is given. |
Prepare(RDbDatabase &, const TDbQuery &, const TDbWindow &)
Prepare(RDbDatabase &, const TDbQuery &, const TDbWindow &, TAccess)
Unevaluated()
| IMPORT_C TBool | Unevaluated | ( | ) | const |
Tests whether any more evaluation can be done to a view.
