Db.truncate

 APIRef 

import com.sleepycat.db.*;


public int truncate(DbTxn txnid, int flags)
	throws DbException;

Description

The Db.truncate interface empties the database, discarding all records it contains. The number of records discarded from the database is returned.

If the operation is to be transaction-protected, the txnid parameter is a transaction handle returned from DbEnv.txn_begin; otherwise, null.

The flags parameter is currently unused, and must be set to 0.

The Db.truncate method throws an exception that encapsulates a non-zero error value on failure.

Errors

The Db.truncate method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the Db.truncate method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
