Vba 将Excel电子表格中的记录与数据库中的记录进行比较
我最初认为我的记录集有问题，但现在看来我已经做了一些修补，当我将null值传递到我的SQL查询字符串中，并将其附加到excute时，它无法识别SQL中的null字符串 乙二醇 rst.OPEN“从XXX中选择*其中Y=int，Z=NULL” 然而，这不起作用 rst.OPEN“从XXX中选择*，其中Y=int，Z=datetime” 工作正常吗Vba 将Excel电子表格中的记录与数据库中的记录进行比较,vba,excel,Vba,Excel,我最初认为我的记录集有问题，但现在看来我已经做了一些修补，当我将null值传递到我的SQL查询字符串中，并将其附加到excute时，它无法识别SQL中的null字符串 乙二醇 rst.OPEN“从XXX中选择*其中Y=int，Z=NULL” 然而，这不起作用 rst.OPEN“从XXX中选择*，其中Y=int，Z=datetime” 工作正常吗 Sub CompareExcel() ' Macro1 Macro ' Macro recorded

Do While RowInSourceSheet属性取决于光标位置和类型。看起来您所做的只是检查是否有任何记录，因此您可以使用：
If Not rst.EOF Then
而不是：
If rst.RecordCount <> 0 Then

是的，对于那些变量名和没有明显声明类型的人来说，这有点棘手。你能给我们一些你的表名的例子吗，因为这在你的代码中看起来非常复杂，当然，我们看不到工作表的内容。嗨，伙计们，问题是我传入的值为Null，它不返回记录集，但是当我复制并粘贴查询到SQL时，它对我来说运行良好。我把null作为一个字符串，也许这就是问题所在？？是的，那行不通。您不能使用=
，您需要使用其中FieldName为Null
作为标准。感谢Rory现在工作得很好
