从其他表访问 Vba 序列 ID

Question

我有两个表，ID 表和 Mastertable。 在 ID 表中，我有级别和活动，它给出了一个起始编号，让我们说 1000。在 Mastertable 中，我有许多与相同活动和级别相关联的图纸。 我必须从 ID 表值 1000 开始为它们提供编号，并将其增加 1。完成后，必须将 mastertable 中的最大值重新插入 ID 表。

此外，如果有级别和活动，则必须选择 ID 来查找级别和活动，如果没有提到级别，则只需查找活动。

我尝试了很多，但没有成功。

我使用了下面的代码，但它只查找活动而不是级别。 它也不会返回到 id 表并从主表更新最大 ID。

Option Compare Database
Option Explicit

Public Function SequenceNew()
Dim strSQL As String
Dim db As Database
Dim rs As DAO.Recordset
Dim a, initNo As Integer
Dim b As Integer


strSQL = "SELECT * FROM MasterTable ORDER BY LevelID"
'Set db = CurrentDb
Set rs = CurrentDb.OpenRecordset(strSQL)
If rs.RecordCount > 0 Then
rs.MoveFirst
Do While Not rs.EOF

rs.Edit
If rs![DrawingTypeName] = "Concrete" And rs![ProjectName] = Forms!frm_Publish!CboProject And rs!IDGiven = "Not Given" Then
a = a + 1
rs!Sequence = DLookup("CONCRETE", "Qry_ID_Selected") + a

ElseIf rs![DrawingTypeName] = "Reinforcement" And rs![ProjectName] = Forms!frm_Publish!CboProject And rs!IDGiven = "Not Given" Then
b = b + 1
rs!Sequence = DLookup("REINFORCEMENT", "Qry_ID_Selected") + b

ElseIf rs![DrawingTypeName] = "Steel structural works" And rs![ProjectName] = Forms!frm_Publish!CboProject And rs!IDGiven = "Not Given" Then

End If
rs.Update
rs.MoveNext
Loop
rs.Close
Set db = Nothing
Else
MsgBox " No records Found"
rs.Close
Set db = Nothing
End If

End Function

应该有其他更好的方法来做到这一点。 主表 ID 表

这个问题是由我可以解决的新代码解决的。
