Query line counter

77 Views
Last Modified: 2017-05-03
I need to use a value that I get from DLookUp("[ID_m]";"tbl_ID_MAKS_VARELNORDRE";"[ID_m]") (there is only ever one record in the table) and add +1 for each line in a query result. I have tried for a few hours now, so any help appreciated. Thanks in advance.

The original query result may look like this:

Sample1     Result 234,4
Sample 15  Result 114,3
Sample 27  Result 43,2

I need the query to return, assuming the DLookup value is 200:

201   Sample1      Result 234,4
202   Sample 15   Result 114,3
203   Sample27    Result 43,2


Best regards,

How are using this query?  Are you displaying this in a form, or a report?

Ryan: Looked at your example. The problem is that there is no unique ID in the query (yourTable). That is the main issue. I need to get the value 200 into the query and add +1 for each line in the query result.

OK. I will try to use your suggestion and some other scripts to get this to work. I will probably need until next week (Easter Holidays).
I will post the solution once I have it.

If you're making a single pass through the recordset you can do a line counter easily.

But if you're going to use this in a form  where you're going to move back-and-forth through the records that then you cannot use that technique.  However depending on the situation at temp table often work.

Thanks Ryan, your solution was the best suggestion - although I ended up with a workaround due to the missing ID-field in the original dataset.
