使用VBA从Excel Workbook中删除查询

Question

我是VBA的新手，正在学习如何将连接添加到Excel中的数据库。我目前有一个宏，可以创建一个名为" query1"的查询，然后查询我的数据库并返回正确的表。我希望能够在将表输出到Excel表之后删除查询，以便我可以在稍微修改的条件下再次运行宏，例如不同的日期。

 Sub Macro2()
'
' Macro2 Macro
'

ActiveWorkbook.Queries.Add Name:="Query1", Formula:= _
    "let" & Chr(13) & "" & Chr(10) & "    Source = Odbc.Query(""dsn=Database"", ""SELECT DISTINCT c.IP_TREND_VALUE AS """"PRODUCT"""", c.IP_TREND_TIME , s.IP_TREND_TIME AS TIMES, s.IP_TREND_VALUE AS """"Wttotal""""#(lf)FROM """"Product"""" AS c , """"wtTotal"""" as s#(lf)#(lf)Where  #(lf)#(tab) c.TIME Between '1-JUN-17 05:59:00' AND '2-" & _
    "JUN-17 05:59:00' AND c.TIME = s.IME#(lf)"")" & Chr(13) & "" & Chr(10) & "in" & Chr(13) & "" & Chr(10) & "    Source" & _
    ""
With ActiveSheet.ListObjects.Add(SourceType:=0, Source:= _
    "OLEDB;Provider=Microsoft.Mashup.OleDb.1;Data Source=$Workbook$;Location=Query1" _
    , Destination:=Range("$A$1")).QueryTable
    .CommandType = xlCmdSql
    .CommandText = Array("SELECT * FROM [Query1]")
    .RowNumbers = False
    .FillAdjacentFormulas = False
    .PreserveFormatting = True
    .RefreshOnFileOpen = False
    .BackgroundQuery = True
    .RefreshStyle = xlInsertDeleteCells
    .SavePassword = False
    .SaveData = True
    .AdjustColumnWidth = True
    .RefreshPeriod = 0
    .PreserveColumnInfo = True
    .ListObject.DisplayName = "Query1"
    .Refresh BackgroundQuery:=False
End With
End Sub

将表放入工作表

之后，我想添加以下内容

ActiveWorkbook.Queries.Delete = Name: = "Query1"

，但显然这不存在。如何删除查询或进行查询，以便可以运行宏而无需删除" query1"？

Answer 1

尝试添加以下行。
ActiveWorkbook.queries((取名或索引

ActiveWorkbook.Queries("Query1").Delete

Answer 2

尝试以下：

For Each Worksheet In ThisWorkbook.Worksheets
    Qcount = Worksheet.QueryTables.Count
    If Qcount > 0 Then
        For Each QueryTable In ws.QueryTables
            QueryTable.Delete
        Next
    End If
Next Worksheet

Answer 3

使用

删除Excel工作簿中的所有查询

Dim Qus As WorkbookQuery
For Each Qus In ActiveWorkbook.Queries
  Qus.Delete
Next
