Too complicated

[sharonir22]

Hi


I have a table containing ID numbers and location data (xxxxxx/yyyyyy)
I have a search form in which you can insert a location (in the format above) and a distance and a query returns all the records that are in stated distance or less.

Problem is my query criteria is too complex.

I created a function that gets the 2 locations and calculates the distance between them.

So i set the location criteria to be:

Distance([table].[location],[Forms]![searchform]![location])<[Forms]![searchform]![distance]

But Access wouldn't let me run the query saying the criteria is too complex and suggesting I use parameters.

I would rather not use parameters. Is there an easy solution I'm missing here?

Tnx a lot in advance

Location data looks like a string. x and y really should be in separate fields. What data type is distance?

Location field is referencing itself as part of criteria. That may be cause of 'too complex'. Don't really understand the function. Post code.

Post the query SQL statement.

sharonir22,

Put yourself in the position of the reader. We do not know you, your environment, nor exactly what you are trying to do. Perhaps you could describe or provide an example complete with input and desired output.

Possibly, but readers have no idea what you are trying to do.

Try again to describe WHAT you want to accomplish in plain English -- no database, no code, no jargon...

For background info you could research Great Circle calculations

I need a list of people that live in a certain radius of my location.

My table- field of ID (num), field of location (string)

Distance- recives 2 locations and calculates the distance between them
(The function works perfectly. )

I want to enter my location data in a form and the distance I need and run the query.

My problem is with the criteria.


Btw June7 I have tried seperating the location but I prefer leaving it as a string. The function separates it for the calculation.

Please post your function code.

The function works perfectly.

???
How do you identify locations? Lat/Long?
Did you see the function(s) in the link I posted?
