Select only unique row/record in mysql

Question

I would like to see how I can get only unique row/records that have a unique city and not care if it\'s capital so for example:

Akron
akron
aKRON
         


        

Answer 1

You can us a function in a GROUP BY to convert all names to upper or lowercase:

 SELECT  city,state_prefix,lattitude,longitude 
        FROM zip_code WHERE city LIKE '$queryString%'
        GROUP BY UPPER(city), UPPER(state_prefix) LIMIT 10

I'm assuming if a city and state match, lattitude and longitude can be safely rolled up.
