Row Number in a Query

Adding a Row Number in your Query.

In this tutorial you will learn how to add a ROW number to a Query.

Take an example Table of some Names.

tblNames
IDFirstName
1Fred
3Barry
4Joan
5Ben
7Will

You wish to add the Row number beside them:

tblNames
Row #IDFirstName
11Fred
23Barry
34Joan
45Ben
57Will

There is no row_number like in SQL Server.

You can achive this in a number of ways:

	RowNum: DCount("[ID]","[tblNames]","[ID]<=" & [ID])
	

See this FREE Tip on DCOUNT.

	SELECT A.*, 
		(SELECT COUNT(*) FROM tblNames WHERE A.ID>=ID) AS RowNum
	FROM tblNames AS A
	ORDER BY A.ID;
	

These are not very efficient so don't use them on large recordsets.

An addition to this could be adding the Ordinal or Suffix of st, nd, rd or th

Just create a Function:

	Function myOrdinal (D as Integer) as String
		Dim Suffix as String
		Select Case D
			Case 1, 21, 31: Suffix = "st"
			Case 2, 22: Suffix = "nd"
			Case 3, 23: Suffix = "rd"
			Case Else: Suffix = "th"
		End Select
		myOrdinal = D & Suffix
	End Function
