标题：[求助]跨库复制表代码怎么改？

1、必须是sqlserver数据库

2、

Dim tran As System.Data.SqlClient.SqlTransaction
try
    Dim conn As new System.Data.SqlClient.SqlConnection("server=voyo;uid=sa;pwd=hailun.;database=Test")
    conn.Open() '打开链接
    tran = conn.BeginTransaction()
    Dim mapping1 As new System.Data.SqlClient.SqlBulkCopyColumnMapping("第一列", "第一列")
    Dim mapping2 As new System.Data.SqlClient.SqlBulkCopyColumnMapping("第二列", "第二列")
    Dim copy As new System.Data.SqlClient.SqlBulkCopy(conn, System.Data.SqlClient.SqlBulkCopyOptions.Default, tran)
    Copy.ColumnMappings.Add(mapping1)
    Copy.ColumnMappings.Add(mapping2)
    copy.DestinationTableName = "表D" '指定服务器上目标表的名称
    copy.WriteToServer(DataTables("表D").basetable)   '你的datatable名字,执行把DataTable中的数据写入DB
    tran.Commit()                                  '提交事务
    msgbox("OK")
catch ex As exception
    msgbox(ex.message)
    tran.Rollback()    '返回False 执行失败!
End try
