DBPROP_REMOVEDELETED

Property group: Rowset

Property set: DBPROPSET_ROWSET

Column? N

Type: VT_BOOL

Typical R/W: R/W

Description: Remove Deleted Rows

If the value of this property is VARIANT_TRUE, the provider removes rows it detects as having been deleted from the rowset. That is, fetching a block of rows that formerly included a deleted row does not return a handle to that row.

Which rows the rowset detects as having been deleted is determined by the DBPROP_OWNUPDATEDELETE and DBPROP_OTHERUPDATEDELETE properties; whether the rowset removes these rows is determined by this property.

This property is independent of the transaction isolation level. While the transaction isolation level in some cases determines whether the rowset can detect a row as having been deleted, it has no effect on whether or not the rowset removes that row.

For programmers accustomed to the cursor model in ODBC, the value of this property is always VARIANT_TRUE for rowsets implemented through dynamic cursors; that is, dynamic cursors always remove deleted rows. Whether static and keyset-driven cursors remove deleted rows depends on the value of this property.
