【问题描述】:
我希望在 VBA 上运行 SQL 查询,它将信息从 MS Access 返回到单元格 A1。
目前,我正在运行 SQL 查询 SELECT AccountNumber, BorrowerName from AccountTable;,它只返回 A 列中的帐号 - 它不返回 BorrowerName。同样,如果我要运行 SELECT * from AccountTable; ,它将只返回 AccountNumber 列。有什么想法吗?
(在Dim conn As New Connection之前忽略)
'runs an sql query
Sub RunQueryOnAccess()
'Declaring year value of 1 month & 2 month
'This is important to compare datasets from 2 months ago & last month
Year_1M = Format(Date - 27, "YYYY")
'Declaring month value of 1 month & 2 month
'This is important to compare datasets from 2 months ago & last month
Month_1M = Format(Date - 27, "MM")
'This translates the current month from number to character format
MonthChar_1 = MonthName(Month_1M, False)
'opens the workbook before
'specifiying the file locations
pStr = "Z:\Danny Tool Test Folder\Monthly Files" & "\" & Year_1M & "\" & _
Month_1M & ". " & MonthChar_1 & " " & Year_1M & "\"
otherFile = "Monthly Reporting Tool"
'checking to see that the reporting tool is open, declaring it as MonthlyRepTool
For Each wb In Application.Workbooks
If wb.Name Like otherFile & "*" Then
Set MonthlyRepTool = Workbooks(wb.Name)
End If
Next wb
Dim RepDash As String
RepDash = "Reporting Dashboard"
Dim conn As New Connection, rec As New Recordset
Dim DBPATH, PRVD, connString, query As String
'Declaring fully qualified name of database. Change it with your database's location and name.
DBPATH = "Z:\Danny Tool Test Folder\Database\MasterFile_February2021.accdb"
'This is the connection provider. Remember this for your interview.
PRVD = "Microsoft.ace.OLEDB.12.0;"
'This is the connection string that you will require when opening the the connection.
connString = "Provider=" & PRVD & "Data Source=" & DBPATH
'opening the connection
conn.Open connString
'the query I want to run on the database.
query = "SELECT AccountNumber, BorrowerName from AccountTable;"
'running the query on the open connection. It will get all the data in the rec object.
rec.Open query, conn
'clearing the content of the cells
Cells.ClearContents
'getting data from the recordset if any and printing it in column A of excel sheet.
If (rec.RecordCount <> 0) Then
Do While Not rec.EOF
Range("A" & Cells(Rows.count, 1).End(xlUp).Row).Offset(1, 0).Value2 = _
rec.Fields(0).value
rec.MoveNext
Loop
End If
'closing the connections
rec.Close
conn.Close
End Sub
【问题讨论】:
-
你没有增加 rec.Fields 它总是设置为第一个字段
-
rec.Fields是一个集合,你只能访问项目0,你需要看.copyfromrecordset或使用rec.Fields(1)也
