Default Access query help

I have a requirement to categorize a field in the employee database.

The requirement is: for any given user designation, if the total number is 10 or more, I need the actual designation itself as the output. However, if a particular designation in the organization is less than 10 in total, the output should be 'Misc - and the grade'.

Also, this will need to be done for each grade as well. For example, though the staff designation 'Software Engineer' count is 15, the designation is present across two grades A and B. So, in the output, for the staff with Grade A will show the actual designation as the count is 11, and for Grade B staff with the desgination 'Software Engineer', since the count is 4, it should display the output as 'Misc - Grade B'.

I would like to achieve this in MS Access 2010. Would highly appreciate if you could help.

Hi Rajesh,

Do you still need help with this?

You need a subquery to create the record counts with the key Designation/Grade. Use this to determine whether "Misc - " & Grade or Designation is returned. You may be able to use the DCount() function.

If you still want help, I'll set up the data and post the SQL required, no point doing all that if you've already solved your problem though.

Hi again,

Here's an example using DCount, a subquery may be better, but I expect the number of records to be queried is never going to be huge, so this should be quick enough.

Code:
SELECT Positions.Username, Positions.Grade, Positions.Designation, IIf(DCount("Designation","Positions","Grade = '" & [Grade] & "' AND Designation = '" & [Designation] & "'")>9,[Designation],"Misc - Grade " & [Grade]) AS [Output Required]
FROM Positions;
I've assumed your table is called Positions, so change accordingly. I only used the grade, that is A, B, C and D in the Grade column as there's no need to store the word Grade in every record, it's inefficient. You should also consider having another table with Designations stored with a unique ID and use that as a foreign key in your Positions table.

HTH.

Malc.
