Answer 1

您必须为K_RT_MasterRetailStores的每个联接使用不同的别名。

Answer 2

其他人说要使用不同的别名，但也许你不清楚它们是什么意思：

 select convert(varchar,FT.date,103)as date, MR_from.branch as frombranch,
        PD.productname as product,FT.vehicleno,FT.dcno,FT.tobranch 
from K_RT_FixedAssetTransfer FT
inner join K_RT_MasterRetailStores MR_from --<-- First alias
           on MR_from.sno = FT.frombranch 
inner join K_RT_ProductDetails PD on PD.sno=FT.product
inner join K_RT_MasterRetailStores MR_to --<-- Second alias
           on MR_to.sno = FT.tobranch 
where FT.date between @fromdate and  @todate

我注意到您没有使用SELECT列表中第二个联接中的任何内容。也许您想使用它代替FT.tobranch？

 select convert(varchar,FT.date,103)as date, MR_from.branch as frombranch,
        PD.productname as product,FT.vehicleno,FT.dcno,MR_to.branch 
from K_RT_FixedAssetTransfer FT
inner join K_RT_MasterRetailStores MR_from on MR_from.sno = FT.frombranch 
inner join K_RT_ProductDetails PD on PD.sno=FT.product
inner join K_RT_MasterRetailStores MR_to on MR_to.sno = FT.tobranch 
where FT.date between @fromdate and  @todate

Answer 3

您已使用相同的别名加入K_RT_MasterRetailStores两次。

根据此连接是否需要两次，您需要

删除第二个联接
使用其他别名

在FROM子句中多次指定相关名称“MR”
