我有数据库有许多表。在第一个表，我有一个名为领域状态。

I have database with many tables. In the first table, I have a field called status.

table 1
idno   name    status
111    hjghf   yes
225    hjgjj   no
345    hgj     yes

其他表可能有相同的 IDNO 用不同的领域。

我想没有检查每个ID的状态，如果是肯定的，那么对于所有表的所有空和空白领域在该ID号我想更新他们为111111。

I want to check the status for each id no and if it is yes then for that id number in all tables for all null and blank fields I want to update them as 111111.

我要寻找一个样本VBA code这个我能适应。

I am looking for a sample vba code for this which I can adapt.

感谢

下面是一些主要未经考验code。希望它会给你一个开始。

Here is some largely untested code. Hopefully it will give you a start.

Sub UpdateNulls()
Dim strSQL As String
Dim rs As DAO.Recordset
For Each tdf In CurrentDb.TableDefs
    If Left(tdf.Name, 4) <> "Msys" And tdf.Name <> "Table1" Then
        strSQL = "Select * From [" & tdf.Name & "] a Inner Join " _
        & "Table1 On a.idno = Table1.idno Where Table1.Status = 'Yes'"

        Set rs = CurrentDb.OpenRecordset(strSQL)

        Do While Not rs.EOF
            For i = 0 To rs.Fields.Count - 1
                If IsNull(rs.Fields(i)) Then
                    rs.Edit
                    rs.Fields(i) = 111111
                    rs.Update
                End If
            Next
            rs.MoveNext
        Loop

    End If
Next
End Sub
