Question: I have a table in Microsoft Access, and I want to show row number in a column using a select query in Access just like using `ROW_NUMBER()` function in SQL Server.

In SQL Server, I can using this query:

```
SELECT ROW_NUMBER() OVER (ORDER BY tblUser.UserID) AS NoRow, * 
FROM tblUser

```

I use same query in access, but I get error.

Can you help me?

Answer: 
One way to do this with MS Access is with a subquery but it does not have anything like the same functionality:

```
SELECT a.ID, 
       a.AText, 
       (SELECT Count(ID) 
        FROM table1 b WHERE b.ID <= a.ID 
        AND b.AText Like "*a*") AS RowNo
FROM Table1 AS a
WHERE a.AText Like "*a*"
ORDER BY a.ID;

```
by VB function:

```
Dim m_RowNr(3) as Variant
'
Function RowNr(ByVal strQName As String, ByVal vUniqValue) As Long
' m_RowNr(3)
' 0 - Nr
' 1 - Query Name
' 2 - last date_time
' 3 - UniqValue

If Not m_RowNr(1) = strQName Then
  m_RowNr(0) = 1
  m_RowNr(1) = strQName
ElseIf DateDiff("s", m_RowNr(2), Now) > 9 Then
  m_RowNr(0) = 1
ElseIf Not m_RowNr(3) = vUniqValue Then
  m_RowNr(0) = m_RowNr(0) + 1
End If

m_RowNr(2) = Now
m_RowNr(3) = vUniqValue
RowNr = m_RowNr(0)

End Function

```

Usage(without sorting option):

```
SELECT RowNr('title_of_query_or_any_unique_text',A.id) as Nr,A.*
From table A
Order By A.id

```

if sorting required or multiple tables join then create intermediate table:

```
 SELECT RowNr('title_of_query_or_any_unique_text',A.id) as Nr,A.*
 INTO table_with_Nr
 From table A
 Order By A.id

```
