Question

我在Excel中使用VBA从MS Access数据库中删除行。我遇到了

“错误3704 - 对象打开时不允许操作”

虽然在使用类似代码时我能够向DB添加信息。当试图删除时，它给我错误。请帮忙！

Sub DeleteOldValues()

'--------------
'DIM STATEMENTS

Dim strMyPath As String, strDBName As String, strDB As String, strSQL As String, StrQuery As String

'instantiate an ADO object using Dim with the New keyword:
Dim adoRecSet As New ADODB.Recordset
Dim connDB As New ADODB.Connection

'--------------
'THE CONNECTION OBJECT

strDBName = "Test.accdb"
strMyPath = "Y:"
strDB = strMyPath & "\" & strDBName

 'Connect to a data source:
connDB.Open ConnectionString:="Provider = Microsoft.ACE.OLEDB.12.0; data source=" & strDB

StrQuery = "DELETE * FROM Table WHERE ProjectName Like '*Project 1*'"

'Performs the actual query
adoRecSet.Open StrQuery, connDB

'--------------
'close the objects
adoRecSet.Close
connDB.Close

'destroy the variables
Set adoRecSet = Nothing  <-error occurs at this point
Set connDB = Nothing

End Sub

您正在删除，因此您还没有记录集。

 'Connect to a data source:
connDB.Open ConnectionString:="Provider = Microsoft.ACE.OLEDB.12.0; data source=" & strDB
StrQuery = "DELETE * FROM Table WHERE ProjectName Like '*Project 1*'"

'Performs the actual query
connDB.Execute strQuery

在大多数情况下，最好使用DAO with MS Access
