0 as CM_Total, Receipt_CLNT.Amt_Rcvd as RcptAmt,Receipt_CLNT.ChqDDNo as RefNo, 
Receipt_CLNT.ChqDDdate as RefDate, Receipt_CLNT.Amt_Mode as Mode, 
Receipt_CLNT.RcptNo as RcptNo, 0 as MemoNo, 0 as MDate, Receipt_CLNT.G_Name
from Receipt_CLNT
ORDER BY Cdate;

如果将问题简化为仅问题部分，它仍然不返回数据吗？

Select 0 as Rcpt_Date, 0 as CmNo, BD.Bdate as BookDate, BD.BNo as LR_No, 
       0 as CM_Total, 0 as Amt_Rcvd, 0 as ChqDDNo, 0 as ChqDDdate, 0 as Acc_Typ, 
       0 as RcptNo,BD.CST as MNo, BD.GRDate as M_Date, BD.Consignee 
from (B_Detail BD 
INNER JOIN Receipt_CLNT CM ON (CM.CNee = BD.Consignee))

如果是这样，则连接（作为内部连接）不匹配任何键。
CM.CNee = BD.收货人
