主题：按时间段统计数值

Dim b As New SQLGroupTableBuilder("统计表1", "操作表")
b.C
b.AddTable("操作表", "sureyid", "主表", "sureyid") '添加统计表
b.Groups.AddDef("cargo") '根据产品名称分组
b.Totals.AddDef("weightofcargo") '对数量进行统计
b.Build '生成统计表
Maintable = Tables("统计表1") '打开生成的统计表

 

假如主表有一列日期列，主表与操作表是通过sureyid进行关联，现在想统计日期列为2023.01.05-2023.08.09,这段时间的货物数量和，应该怎么改？也就是主表加了一个日期范围，

b.filter = "日期>=#01/05/2023# and 日期<=#08/09/2023#"

运行后提示我#附近有语法错误呢？

还是相同实例，b.Groups.AddDef("cargo") '根据产品名称分组，这句，假如cargo列分别有产品a，b，c，我现在只想得到产品b的统计结果，不需要a和 c的，怎样直接得到？

b.filter = "cargo='b'"

解决了：b.Filter = "[客户] = 'CS01'"

b.Totals.AddDef("重量") '对数量进行统计，现在想新增统计项，对操作表中的“重量”列进行求和，前提是操作表中“次数”列等于1的行，怎样写？

b.filter = "次数=1"

Dim b As New SQLGroupTableBuilder("统计表1", "操作表")
b.C
b.AddTable("操作表", "sureyid", "主表", "sureyid") '添加统计表
b.Groups.AddDef("cargo") '根据产品名称分组
b.Totals.AddDef("weightofcargo") '对数量进行统计
b.Totals.AddDef("bl") '对数量进行统计
Dim filter As String

With e.Form.Controls("StartDate1")
    If .Value IsNot Nothing Then
        Filter = "日期 >= '" & .Value & "'"
    End If
End With
With e.Form.Controls("EndDate1")
    If .Value IsNot Nothing Then
        If Filter > "" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "日期 <= '" & .Value & "'"
    End If
End With
With e.Form.Controls("货物")
    If .Value IsNot Nothing Then
        If Filter > "" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "[cargo]= '" & .Value & "'"
    End If
End With
With e.Form.Controls("船代")
    If .Value IsNot Nothing Then
        If Filter > "" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "[company]= '" & .Value & "'"
    End If
End With

'b.filter = "日期>='01/05/2023' and 日期<='08/09/2023' and [cargo] = '煤'"
If Filter > "" Then

    b.filter = filter & "and 次数=1"
   
    Tables("主表_Table5").DataSource = b.BuildDataSource()
    ' Maintable = Tables("统计表1") '打开生成的统计表
    'b.Build '生成统计表

Else
    messagebox.Show("请填入选项再搜索")
End If

 

修改黄色部分后，现在weightofcargo那列没有数值了
