![]() ![]() (For those who wants to geek out on SQL internals, Itzik Ben-Gan, a SQL Server MVP has a great post that outlines the logical query processing. It seems strange to put a ResetRowNumber() call in a WHERE clause, doesn’t it? However, the WHERE clause is actually resolved prior to the SELECT clause. SELECT RowNumber(TablePrimaryKey) As RowNum Then within your query’s SQL, you should call the functions as so: Public Function RowNumber(UniqueKeyVariant As Variant) As Long Public Function ResetRowNumber() As Boolean We need to create a brand new VBA standard module and define a module-level variable, and two functions: To do this entirely in a query, we need a bit of help from the VBA. Sometimes we do need to export a content of query and therefore we can’t use a report (or at least we don’t want extraneous formatting contents when we try to export a report). The Running Sum method works great as long you are happy with creating and running an Access report, but not all requirements want the data in an Access report. You can use the “Running Sum” property of a textbox on a report to do all the work for you: If your objective is to generate a report, then you don’t want numbering to be a part of your query but rather a part of the report itself. Let’s look at few sequential numbering methods that can be done entirely in Access… 2. In fact, we have had run into cases like this and we can still do it without the ROW_NUMBER() function. Swell, but I don’t have a SQL Server backend. This was introduced in SQL Server 2005 so chances are high you can use it if you can create views. This is probably the simplest, no-nonsense method that works well for any purposes. If you have a SQL Server backend, you could just use the windows function ROW_NUMBER() and define it as a part of a SQL Server view. So, what are our options? There are actually several ways, each with its pros and cons. In other words, if someone creates a record then later deletes it, there will be a gap in the sequence. We cannot just use the auto-number data type because there is no promise of sequentiality but only uniqueness. Occasionally we come across project requirements that include the ability to do sequential numbering in Access on a set of data.
