我需要一个代码来循环遍历表中的所有记录，以便我可以提取一些数据。除此之外，还可以循环过滤记录，并再次提取数据吗？谢谢！
您应该可以使用非常标准的DAO记录集循环来完成此操作。您可以在以下链接中看到一些示例： http://msdn.microsoft.com/en-us/library/bb243789%28v=office.12%29.aspx http://www.granite.ab.ca/access/email/recordsetloop.htm
我自己的标准循环看起来像这样：
Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM Contacts")
'Check to see if the recordset actually contains rows
If Not (rs.EOF And rs.BOF) Then
rs.MoveFirst 'Unnecessary in this case, but still a good habit
Do Until rs.EOF = True
'Perform an edit
rs.Edit
rs!VendorYN = True
rs("VendorYN") = True 'The other way to refer to a field
rs.Update
'Save contact name into a variable
sContactName = rs!FirstName & " " & rs!LastName
'Move to the next record. Don't ever forget to do this.
rs.MoveNext
Loop
Else
MsgBox "There are no records in the recordset."
End If
MsgBox "Finished looping through records."
rs.Close 'Close the recordset
Set rs = Nothing 'Clean up
在“引用”中，导入DAO 3.6对象引用。
private sub showTableData
dim db as dao.database
dim rs as dao.recordset
set db = currentDb
set rs = db.OpenRecordSet("myTable") 'myTable is a MS-Access table created previously
'populate the table
rs.movelast
rs.movefirst
do while not rs.EOF
debug.print(rs!myField) 'myField is a field name in table myTable
rs.movenext 'press Ctrl+G to see debuG window beneath
loop
msgbox("End of Table")
end sub
您可以通过不同方式迭代查询和过滤表等数据对象：
通过查询：
private sub showQueryData
dim db as dao.database
dim rs as dao.recordset
dim sqlStr as string
sqlStr = "SELECT * FROM customers as c WHERE c.country='Brazil'"
set db = currentDb
set rs = db.openRecordset(sqlStr)
rs.movefirst
do while not rs.EOF
debug.print("cust ID: " & rs!id & " cust name: " & rs!name)
rs.movenext
loop
msgbox("End of customers from Brazil")
end sub
您还应该查找记录集对象的“Filter”属性，以仅过滤所需的记录，然后以相同的方式与它们进行交互（请参阅MS-Access代码窗口中的VB6帮助），或创建“QueryDef”对象以运行查询并将其用作记录集（稍微有点棘手）。告诉我你是否想要另一种方法。
我希望我能帮到你。
找到一个很好的代码，其中包含解释每个语句代码发现于 - accessallinone
Sub DAOLooping()
On Error GoTo ErrorHandler
Dim strSQL As String
Dim rs As DAO.Recordset
strSQL = "tblTeachers"
'For the purposes of this post, we are simply going to make
'strSQL equal to tblTeachers.
'You could use a full SELECT statement such as:
'SELECT * FROM tblTeachers (this would produce the same result in fact).
'You could also add a Where clause to filter which records are returned:
'SELECT * FROM tblTeachers Where ZIPPostal = '98052'
' (this would return 5 records)
Set rs = CurrentDb.OpenRecordset(strSQL)
'This line of code instantiates the recordset object!!!
'In English, this means that we have opened up a recordset
'and can access its values using the rs variable.
With rs
If Not .BOF And Not .EOF Then
'We don’t know if the recordset has any records,
'so we use this line of code to check. If there are no records
'we won’t execute any code in the if..end if statement.
.MoveLast
.MoveFirst
'It is not necessary to move to the last record and then back
'to the first one but it is good practice to do so.
While (Not .EOF)
'With this code, we are using a while loop to loop
'through the records. If we reach the end of the recordset, .EOF
'will return true and we will exit the while loop.
Debug.Print rs.Fields("teacherID") & " " & rs.Fields("FirstName")
'prints info from fields to the immediate window
.MoveNext
'We need to ensure that we use .MoveNext,
'otherwise we will be stuck in a loop forever…
'(or at least until you press CTRL+Break)
Wend
End If
.close
'Make sure you close the recordset...
End With
ExitSub:
Set rs = Nothing
'..and set it to nothing
Exit Sub
ErrorHandler:
Resume ExitSub
End Sub
在循环数据，EOF（文件结束）和BOF（文件开头）时，记录集有两个重要的属性。记录集就像表格一样，当你遍历一个记录集时，你就会按顺序从一个记录移动到另一个记录。当您在记录中移动时，EOF属性设置为false，但在尝试跳过最后一条记录后，EOF属性将变为true。对于BOF属性，它的反向相同。
当我们达到记录集的限制时，这些属性会告诉我们。
