分表问题更新数量+1问题 返回

var u = Context.Updateable(main)    .IgnoreNullColumns()    .IgnoreColumns(it => new { it.Create_Time, it.Create_User })    .PublicSetColumns(it => it.Packed_Qty, it => SqlFunc.IsNull(it.Packed_Qty, 0) + 1)    .WhereColumns(it => new { it.Id })    .SplitTable(tabs => tabs.Take(6)) 分表情况下,更新累计+1时,使用上面的语句会导致累计重复,实际有几张表,就会重复更新几次;如下,是有2个实体表时,sql被执行了2次;这个是bug还是我的写法有问题?

UPDATE [Packing_Main_20260901]  SET           [Plan_Qty]=2,[Packed_Qty]=(ISNULL([Packed_Qty],0) + 1 ) WHERE [Id]=353558359535783936
