主题：老师，我明细有1月到3月的数据明细，目前3月份，我想根据成品编码，发货明细只汇总3月份的数据，请帮忙看看，谢谢

1、分组统计参考

2、日期条件的合成，参考

比如代码

Dim y As Integer = Date.Today.Year
Dim m As Integer = Date.Today.Month
Dim dt1 As New Date(y, m, 1)
Dim dt2 As New Date(y, m, Date.DaysInMonth(y, m)) '获取本月的最后一天
Dim Filter As String
Filter = "操作日期 >= #" & dt1 & "# And 操作日期 <= #" & dt2 & "# and 操作类型 = '产成入库'"
Tables("入库明细").Filter = Filter

分别统计，如 http://www.foxtable.com/webhelp/scr/0681.htm
