The DeleteDataKey method deletes a row of data, based on the provided key value.
Syntax
HRESULT DeleteDataKey(
VARIANT vtReserved,// in
VARIANT vtKey// in
);
Parameters
-
vtReserved
-
This parameter is reserved for future use, and is ignored by the current implementation of DeleteDataKey.
-
vtKey
-
A VARIANT that contains the key value for the row to delete. This key corresponds to the column designated as the table key in the initial call to IDBStorage::InitStorage. Thus, if the call to InitStorage specifies column “some_column” as the table key, then DeleteDataKey searches “some_column” for the value stored in vtKey, and deletes the corresponding row of data.
