Can I compare numeric values from an auto number data type field in an SQL query?

I have to iterate between thousand of records and I was thinking of using a uniqueid field that I have, but I cant use the numeric value of it. Seems its treated like string. Is there any way that I can compare numeric values with auto number values?

AND (uniqueid__c > i AND uniqueid__c < i+5000)

You might not be able to achieve what you want using Aggregate SOQL query. Instead I recommend querying all of the records and looping through them while picking the ones that do fall within the range that you want. E.g.
  
// Store query results here in variable queryResults

// declare set of object you need in set recordSet

for (result : queryResults) {
    if (Integer.valueOf(result.uniqueid__c) > i && Integer.valueOf(result.uniqueid__c) < i+5000) {
		recordSet.add(result);
    }
}

Hope this helps

Hi,

This can be done easily if the formatting of the autonumber field is only numeric. Otherwise you might have to parse the string or use some sort of sortible interface to achieve what you want. 

Hope this helps!

I tried this .. AND (Integer.valueOf(uniqueid__c) > i AND Integer.valueOf(uniqueid__c) < i+5000)
And it gives me ... expecting a colon, found 'i'

i tried this AND (Integer.valueOf('uniqueid__c') > i AND Integer.valueOf('uniqueid__c') < i+5000)
and it gives me ... unexpected token: 'uniqueid__c'

Stupid of me, I had to include the field in the SELECT first. But even when I included ...

I used ...   (Integer.valueOf(uniqueid__c) > :i AND Integer.valueOf(uniqueid__c) < :i+5000)

And the result is
Invalid aggregate function: Integer.valueOf
