public void Delete( DatabaseEntry key, Transaction txn )
|Visual Basic (Declaration)|
Public Sub Delete ( _ key As DatabaseEntry, _ txn As Transaction _ )
public: void Delete( DatabaseEntry^ key, Transaction^ txn )
- Type: BerkeleyDB..::.DatabaseEntry
Discard the key/data pairs associated with key.
- Type: BerkeleyDB..::.Transaction
If the operation is part of an application-specified transaction, txn is a Transaction object returned from BeginTransaction()()(); if the operation is part of a Berkeley DB Concurrent Data Store group, txn is a handle returned from BeginCDSGroup()()(); otherwise null.
When called on a secondary database, remove the key/data pairs from the primary database and all secondary indices.
If txn is null and the operation occurs in a transactional database, the operation will be implicitly transaction protected.
|BerkeleyDB..::.NotFoundException||A NotFoundException is thrown if key is not in the database.|
|BerkeleyDB..::.KeyEmptyException||A KeyEmptyException is thrown if the database is a QueueDatabase or RecnoDatabase database and key exists, but was never explicitly created by the application or was later deleted.|
