Question

我在VBA中创建了一个循环，它应该改变代码的strSql部分中的变量（j）。 excel表上的输出列都是缩进的。这意味着在strsql字符串中不考虑更改变量j。在这种情况下，有人知道如何使用适当的变化变量吗？提前致谢

设置rs =新ADODB.Recordset

     For j = 1 To 6


    strSql = "SELECT COUNT(*) FROM( " & _
     "SELECT COUNT(*) as nbp FROM `order`   " & _
     "JOIN user ON user.id = order.destination_id   " & _
     "AND DATEDIFF(date_added , register_date) <= j" & _
     "GROUP BY destination_id)  c  " & _
     "GROUP BY nbp " & _
     "ORDER BY c.nbp ASC ; "



    rs.Open strSql, oConn, adOpenDynamic, adLockPessimistic

    res = rs.GetRows

    rs.Close

    For i = 1 To 2
    Cells(i, j) = res(0, i - 1)
    Next i
    Next j

Answer 1

你需要将j移出你的字符串

register_date）＆lt; = j“＆amp;

要

register_date）＆lt; =“＆amp; j＆amp;

Answer 2

相当令人讨厌，但在vba与ado我猜这是最快的黑客...你不需要将j转换为字符串但我宁愿明确......

strSql = "SELECT COUNT(*) FROM( " & _
     "SELECT COUNT(*) as nbp FROM `order`   " & _
     "JOIN user ON user.id = order.destination_id   " & _
     "AND DATEDIFF(date_added , register_date) <= " & _ 
     CStr(j) & " " & _
     "GROUP BY destination_id)  c  " & _
     "GROUP BY nbp " & _
     "ORDER BY c.nbp ASC ; "

在VBA mysql查询中用循环更改变量？
