Question

我需要在代码中添加一些SQL，但不完全确定在哪里添加它。

当前代码：

Me.List5.RowSource = "SELECT  TOP " & Nz(Me.Text9.Value, 0) & " RTI.CRN,
                              Sum(RTI.Credit) AS Credit,
                              Count(RTI.CRN) AS [Count]
                      FROM    RTI
                      GROUP BY  RTI.CRN
                      ORDER BY  Sum(RTI.Credit) DESC;"

我需要添加一个部件来搜索文本框中的日期。我想我需要以下代码：

AND [StatusDateTime] >= [Text1] AND <= [Text2]

我的日期代码是对的吗？我在哪里将它添加到原始SQL？

谢谢

Answer 1

该条件会过滤生成的集合，因此它位于WHERE子句中，其位置恰好位于FROM之后。

你可以这样写这个条件

[StatusDateTime] >= [Text1] AND [StatusDateTime] <= [Text2]

或此（更紧凑）方式

[StatusDateTime] between [Text1] and [Text2]

结果查询将是

Me.List5.RowSource = "SELECT TOP " & Nz(Me.Text9.Value, 0) & " RTI.CRN,
                             Sum(RTI.Credit) AS Credit,
                             Count(RTI.CRN) AS [Count]
                      FROM   RTI
                      WHERE  [StatusDateTime] between [Text1] and [Text2]
                      GROUP BY  RTI.CRN
                      ORDER BY Sum(RTI.Credit) DESC;"

Answer 2

1）你应该在“FROM RTI”之后添加它

2）应该是

AND [StatusDateTime] >= [Text1] AND [StatusDateTime] <= [Text2]

或者

AND [StatusDateTime] BETWEEN [Text1] AND [Text2]

按日期范围过滤SQL
