主题：如何在filter中使用变量

Dim bd1 As New GroupTableBuilder("查询统计表",DataTables("生产统计表"))

Dim rq1 As Date= e.Form.Controls("DateTimePicker1").Value

Dim rq2 As Date= e.Form.Controls("DateTimePicker2").Value

Dim yuan As fxDataSource

bd1.Groups.AddDef("图号名称") '根据图号分组

bd1.Filter="[生产时间] >= #rq1# And [生产时间] <= #rq2# "  ‘ 根据DateTimePicker的值过滤

bd1.Totals.AddDef("生产数量","生产总量") ' 对数量进行统计

yuan = bd1.BuildDataSource()
