我正在Excel文件中运行一些VBA,以便在Excel中进行数据操作后更新Access数据库。它通过DAO链接创建并执行SQL行。有时,要输入的数据包含破坏SQL的字符(例如INSERT INTO语句的值中的撇号),因此错误捕获参数化查询语句会尝试进行这些更改。
清除旧错误后,查询语句在运行时返回错误“Object required”,但它确实有效(数据库以正确的方式修改)。问题是:为什么它会返回此错误并且我做错了什么?这可能是一个问题吗?
初始错误的代码摘要:
Dim TableName As String, FieldString As String
Dim strSQL As String, valstring As String
Dim NewTableRef As Range
Dim rs As DAO.Recordset, ws As DAO.Workspace, db As DAO.Database
' Fieldstring is a string containing all field names for the table to be changed'
' TableName is the table to be changed'
' Connecting to database and setting ranges done previously'
' strSQL is initially set by the type of change to make'
' modify the recordset'
On Error Resume Next
db.Execute (strSQL)
If Err <> 0 Then
' Only an issue for inputs to Table1'
If TableName = "Table1" Then
' try it with parameters'
strSQL = "PARAMETERS @var1 TEXT, @var2 TEXT, @var3 TEXT, @var4 TEXT, @var5 TEXT;" _
& "INSERT INTO " & TableName & " (" & FieldString & ") " & " VALUES (@var1,@var2,@var3,@var4,@var5);"
Set qdf = db.CreateQueryDef("", strSQL)
qdf!var1 = NewTableRef.Offset(Row - NewTableRef.Row, 1).Value
qdf!var2 = NewTableRef.Offset(Row - NewTableRef.Row, 2).Value
qdf!var3 = NewTableRef.Offset(Row - NewTableRef.Row, 3).Value
qdf!var4 = NewTableRef.Offset(Row - NewTableRef.Row, 4).Value
qdf!var5 = NewTableRef.Offset(Row - NewTableRef.Row, 5).Value
Err.Clear
Error.Clear
qdf.Execute
If Err <> 0 Then
With ThisWorkbook.Sheets("DB Error Log").Range("Error_Log")
.Columns(1).Offset(ErrNum).Value = Now()
.Columns(2).Offset(ErrNum).Value = ii
.Columns(3).Offset(ErrNum).Value = TableName
.Columns(4).Offset(ErrNum).Value = PKey
.Columns(5).Offset(ErrNum).Value = Error(Err)
.Columns(6).Offset(ErrNum).Value = valstring
ErrNum = ErrNum + 1
Debug.Print ErrNum
End With
End If
Else

答案 0 :(得分:2)
Error
是一个从错误号返回错误描述的函数;它不是一个对象,因此您无法使用Error.Clear
- 从代码中删除它。
