这是VBA中ADODB连接的作业。这是一个带有简单SELECT查询示例代码的链接,但这也将处理存储过程。

关键项目申报的需要ADODB.Connection
,ADODB.Recordset
和匹配您的数据库连接字符串。打开连接后,使用如下语法(从链接中获取)执行SQL语句:
With cnt
.CursorLocation = adUseClient
.Open stADO // stADO is the connection string.
.CommandTimeout = 0
Set rst = .Execute(stSQL)
End With
然后使用将记录集(rst
,上面)中的数据移动到一个范围内Range.CopyFromRecordSet
。
这个VBA与@Excellll的答案非常相似,我在自己的工作中使用它很有效。
使用这个小实用功能:
Public Function IsEmptyRecordset(rs As Recordset) As Boolean
IsEmptyRecordset = ((rs.BOF = True) And (rs.EOF = True))
End Function
然后这是一个重要的功能(我为看起来很糟糕的段落对齐道歉):
Option Explicit
Public Sub OpenConnection()
Dim conn As ADODB.Connection
Dim str As String
Dim cmd As ADODB.Command
Dim rs As ADODB.Recordset
Dim myPath
Dim fld
Dim i As Integer
On Error GoTo errlbl
'Open database connection
Set conn = New ADODB.Connection
'First, construct the connection string.
'NOTE: YOU CAN DO THIS WITH A STRING SPELLING OUT THE ENTIRE CONNECTION...
'conn.ConnectionString = _
' "Provider=Microsoft.Jet.OLEDB.4.0;" & _
' "Data Source=" & _
' myPath & "\ConnectionTest.mdb"
'...OR WITH AN ODBC CONNECTION YOU'VE ALREADY SET UP:
conn.ConnectionString = "DSN=myDSN"
conn.Open 'Here's where the connection is opened.
Debug.Print conn.ConnectionString 'This can be very handy to help debug!
Set rs = New ADODB.Recordset
'Construct string. This can "Select" statement constructed on-the-fly,
'str = "Select * from vwMyView order by Col1, Col2, Col3"
'or an "Execute" statement:
str = "exec uspMyStoredProc"
rs.Open str, conn, adOpenStatic, adLockReadOnly ‘recordset is opened here
If Not IsEmptyRecordset(rs) Then
rs.MoveFirst
'Populate the first row of the sheet with recordset’s field names
i = 0
For Each fld In rs.Fields
Sheet1.Cells(1, i + 1).Value = rs.Fields.Item(i).Name
i = i + 1
Next fld
'Populate the sheet with the data from the recordset
Sheet1.Range("A2").CopyFromRecordset rs
Else
MsgBox "Unable to open recordset, or unable to connect to database.", _
vbCritical, "Can't get requested records"
End If
'Cleanup
rs.Close
Set rs = Nothing
conn.Close
Set conn = Nothing
exitlbl:
Debug.Print "Error: " & Err.Number
If Err.Number = 0 Then
MsgBox "All data has been pulled and placed on Sheet1", vbOKOnly, "All Done."
End If
Exit Sub
errlbl:
MsgBox "Error #: " & Err.Number & ", Description: " & Err.Description, _ vbCritical, "Error in OpenConnection()"
Exit Sub
'Resume exitlbl
End Sub
希望这可以帮助。
