Berkeley DB .NET API Documentation

QueueDatabase Class See Also

Append the data item to the end of the database.

Namespace: BerkeleyDB
Assembly: libdb_dotnet48 (in libdb_dotnet48.dll) Version: 4.8.24.0

# Syntax

C#

    public uint Append(
    	DatabaseEntry data,
    	Transaction txn
    )

Visual Basic (Declaration)

    Public Function Append ( _
    	data As DatabaseEntry, _
    	txn As Transaction _
    ) As UInteger

Visual C++

    public:
    unsigned int Append(
    	DatabaseEntry^ data,
    	Transaction^ txn
    )

#### Parameters

data
  Type: BerkeleyDB..::.DatabaseEntry
  The data item to store in the database

txn
  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.

#### Return Value

The record number allocated to the record

# Remarks

There is a minor behavioral difference between Append(DatabaseEntry) and Append(DatabaseEntry). If a transaction enclosing an Append operation aborts, the record number may be reallocated in a subsequent Append(DatabaseEntry) operation, but it will not be reallocated in a subsequent Append(DatabaseEntry) operation.
