I'm a newbie with SQL... Now I want to do display some instances of AddrDistances from DevExpress CxGrid with SQL.

Select Cast((DistanceAsMeters * 0.001) as Decimal(8,1)) DistanceAsKm, bold_id, created, fromAddress, toAddress
From AddrDistance
Where  DistanceAsMeters = 0 and PseudoDistanceAsCostKm = 0
       and not AddrDistance.bold_id in (select bold_id from DistanceQueryTask)
Order By Created Desc

This SQL is working and the result is:

DistanceAsKM Bold_ID    Created      FromAddress ToAddress
0            134808     16.02.2010   121795      134570 
0            121701     10.03.2010   120850      122991   

The result I want is this:

DistanceAsKM Bold_ID    Created      FromAddress ToAddress
0            134808     16.02.2010   Kalmar      Stockholm 
0            121701     10.03.2010   Falkenberg  Oslo   

So the amount of rows is right but I want to replace the numbers in FromAddress and ToAddress with strings from another table. The numbers shows here is just the boldid. Every object in the database have an unique boldid. The addresses above is stored in table Address and it have a City field with the column and a boldid as a key.

What should I write in SQL to get this right ? Is there something in the CxGrid that could help here ?
