[求助]为什么这段代码执行起来这么吃力？ - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

代码：

Select Case e.DataCol.Name

Case "AutoID"

Dim dr As DataRow = DataTables("PODetails").SQLFind("AutoID= " & e.NewValue)

e.DataRow("StyleID") = dr("StyleID")

e.DataRow("PO") = dr("PO")

e.DataRow("Model") = dr("Model")

e.DataRow("Color") = dr("Color")

e.DataRow("Material") = dr("Material")

e.DataRow("Country") = dr("Country")

'提取库存

e.DataRow("RKSize1") = DataTables("TabRKBill").SQLCompute("Sum(Size1)","AutoID = " & e.NewValue)

e.DataRow("CKSize1") = DataTables("TabCKBill").SQLCompute("Sum(Size1)","AutoID = " & e.NewValue)

e.DataRow("RKSize2") = DataTables("TabRKBill").SQLCompute("Sum(Size2)","AutoID = " & e.NewValue)

e.DataRow("CKSize2") = DataTables("TabCKBill").SQLCompute("Sum(Size2)","AutoID = " & e.NewValue)

e.DataRow("RKSize3") = DataTables("TabRKBill").SQLCompute("Sum(Size3)","AutoID = " & e.NewValue)

e.DataRow("CKSize3") = DataTables("TabCKBill").SQLCompute("Sum(Size3)","AutoID = " & e.NewValue)

e.DataRow("RKSize4") = DataTables("TabRKBill").SQLCompute("Sum(Size4)","AutoID = " & e.NewValue)

e.DataRow("CKSize4") = DataTables("TabCKBill").SQLCompute("Sum(Size4)","AutoID = " & e.NewValue)

e.DataRow("RKSize5") = DataTables("TabRKBill").SQLCompute("Sum(Size5)","AutoID = " & e.NewValue)

e.DataRow("CKSize5") = DataTables("TabCKBill").SQLCompute("Sum(Size5)","AutoID = " & e.NewValue)

e.DataRow("RKSize6") = DataTables("TabRKBill").SQLCompute("Sum(Size6)","AutoID = " & e.NewValue)

e.DataRow("CKSize6") = DataTables("TabCKBill").SQLCompute("Sum(Size6)","AutoID = " & e.NewValue)

e.DataRow("RKSize7") = DataTables("TabRKBill").SQLCompute("Sum(Size7)","AutoID = " & e.NewValue)

e.DataRow("CKSize7") = DataTables("TabCKBill").SQLCompute("Sum(Size7)","AutoID = " & e.NewValue)

e.DataRow("RKSize8") = DataTables("TabRKBill").SQLCompute("Sum(Size8)","AutoID = " & e.NewValue)

e.DataRow("CKSize8") = DataTables("TabCKBill").SQLCompute("Sum(Size8)","AutoID = " & e.NewValue)

e.DataRow("RKSize9") = DataTables("TabRKBill").SQLCompute("Sum(Size9)","AutoID = " & e.NewValue)

e.DataRow("CKSize9") = DataTables("TabCKBill").SQLCompute("Sum(Size9)","AutoID = " & e.NewValue)

End Select

选择AutoID之后，然后这一行等全部统计出来得2-3秒。。。

能不能做一些优化？
