混合数据库中两个表的数据

I have two tables, one called location_name it looks like this,

location  shortname longname  precolor     color     hidden

       1    STO     Stockholm   #00FF00     #FF0000     0
       2    GBG     Gothenburg  #00FFFF     #FF00FF     0
       3    MMO     Malmö      #C6C6C6     #008000     0
       4    CPH     Copenhagen  #FF0080     #FF8000     0
       5    ARH     Ã…rhus      #80FF80     #8000FF     1
       6    SER     Service     #FFFF00     #FFFF00     1

and the other one, called art_tot, looks lite this

artnr   art     art_text     gnr       gnr_group    sortorder   hide    location    
220101  Thing   description  2201      1            101         0       3
220102  Thing   description  2201      1            102         0       2 
220103  Thing   description  2201      1            103         0       3 

and im making a that looks something like this

 Pos    Equipment   Artnr  Mon 27-10-2014   Tue 28-10-2014  Wed 29-10-2014  Thu 30-10-2014  Fri 31-10-2014  Sat 01-11-2014  Sun 02-11-2014
 STO    Thing       220101
 STO    Thing       220102
 STO    Thing       220103
 STO    Thing       222001

What i need to do is, color the Pos to the correct color from location_name and have the correct shortname and have the title be the longname.

So i somehow have to make the the Pos TD get the correct values from location_name based on the location column from art_tot

Or is there a simpler way to do this?

i read about JOIN and ended up doing :

$sql ="SELECT a.art_text , a.art , a.art , a.artnr , b.color , b.longname, b.shortname
        FROM art_tot a , location_name b 
        where gnr_group =1 AND a.location = b.location
        order by sortorder" ;

It works like a charm, thanks @dwhite.me
