主题：[求助]帮我看一下这个多表统计代码，错在哪里。

Dim bd1 As New SQLGroupTableBuilder("统计表1","长期医嘱")
Dim dt1 As fxDataSource
bd1.AddTable("长期医嘱","住次ID","住院主表","住次ID")
bd1.Groups.AddDef("姓名") '根据品名分组
bd1.Groups.AddDef("收费项目") '根据品名分组
bd1.Groups.AddDef("项目类别") '根据型号分组
bd1.Groups.AddDef("项目规格") '根据品名分组
bd1.Groups.AddDef("单位") '根据型号分组
bd1.Groups.AddDef("单价") '根据型号分组
bd1.Totals.AddExp("长期医嘱_报数","[数量]") '对数量进行统计
bd1.Totals.AddExp("长期医嘱_金额","[报数] * [单价]") '对数量进行统计
dt1 = bd1.BuildDataSource()

 
Dim bd2 As New SQLGroupTableBuilder("统计表2","临时医嘱")
Dim dt2 As fxDataSource
bd2.AddTable("临时医嘱","住次ID","住院主表","住次ID")
bd2.Groups.AddDef("姓名") '根据品名分组
bd2.Groups.AddDef("收费项目") '根据品名分组
bd2.Groups.AddDef("项目类别") '根据型号分组
bd2.Groups.AddDef("项目规格") '根据品名分组
bd2.Groups.AddDef("单位") '根据型号分组
bd2.Groups.AddDef("单价") '根据型号分组
bd2.Totals.AddExp("临时医嘱_报数","[数量]") '对数量进行统计
bd2.Totals.AddExp("临时医嘱_金额","[报数] * [单价]") '对数量进行统计
dt2 = bd2.BuildDataSource()

Dim nms As String() = {"姓名","收费项目","项目类别","项目规格","单位","单价"}
dt1.Combine(nms,dt2,nms)'将销售统计数据组合到进货统计数据

Tables("窗口1_Table1").DataSource = dt1 '将统计结果绑定到Table
With DataTables("窗口1_Table1").DataCols  '用表达式列计算库存数据
    .Add("数量",Gettype(Integer), "IsNull([长期医嘱_报数],0) + ISNULL([临时医嘱_报数],0)")
    .Add("金额",Gettype(Double), "IsNull([长期医嘱_金额],0) + ISNULL([临时医嘱_金额],0)")
End With
