按时段筛选数据
我们经常需要筛选某个时段的数据，下面列出了各种情况的筛选代码给大家参考。
筛选指定年份数据
例如筛选2011年的订单：
Dim y As Integer = 2011 \'指定年份
Dim dt1 As New Date(y, 1, 1)
Dim dt2 As New Date(y, 12, 1)
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter
筛选指定月份数据
例如筛选2011年6月份的订单：
Dim y As Integer = 2011 \'指定年份
Dim m As Integer = 6 \'指定月份
Dim dt1 As New Date(y, m, 1)
Dim dt2 As New Date(y, m, Date.DaysInMonth(2011,6)) \'获取该月的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter
筛选指定季度的数据
例如筛选2011年2季度的订单：
Dim y As Integer = 2011 \'指定年份
Dim q As Integer = 2 \'指定季度
Dim dt1 As New Date(y, 3 * (q - 1) + 1, 1) \'获取该季度的第一天
Dim dt2 As New Date(y, 3 * q, Date.DaysInMonth(2011,3 * q)) \'获取该季度的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter
筛选本年数据
例如筛选本年的订单：
Dim y As Integer = Date.Today.Year
Dim dt1 As New Date(y, 1, 1)
Dim dt2 As New Date(y, 12, 31)
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter
筛选本季度数据
例如筛选本季度的订单：
Dim y As Integer = Date.Today.Year
Dim q As Integer = (Date.Today.Month - 1) \\ 3 + 1 \'计算现在是第几个季度
Dim dt1 As New Date(y, 3 * (q - 1) + 1, 1) \'获取本季度的第一天
Dim dt2 As New Date(y, 3 * q, Date.DaysInMonth(2011,3 * q)) \'获取本季度的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter
筛选本月数据
例如筛选本月的订单：
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 = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter
筛选本周数据
例如筛选本周的订单：
Dim y As Integer = Date.Today.Year
Dim w As Integer = Date.Today.DayOfWeek \'算出今天是星期几
Dim dt1 As Date = Date.Today.AddDays(-w) \'获取本周的第一天
Dim dt2 As Date = Date.Today.AddDays(6 - w) \'获取本周的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter
