sql语句求助？

(Pwd = @pwd) AND (bbNumber = @bb) OR
(Pwd = @pwd) AND (ccNumber = @cc) OR
(Pwd = @pwd) AND (CallCenterNumber=@hujiao) OR
(Pwd = @pwd) AND (MsgNumber = @msg) OR
(Pwd = @pwd) AND (XunHuNumber = @xunhu) OR
(Pwd = @pwd) AND (CunChuNumber = @cunchu) OR
(Pwd = @pwd) AND (VirtualNumber = @vpn) OR
(Pwd = @pwd) AND (DataExNumber = @dataex) OR
