Update table in sql with join

I want to update a table with a join - why cant I do this?
UPDATE temp_lkltn 
JOIN   job AS j 
ON     temp_lkltn.lastoflocation = j.jobid 
SET    temp_lkltn.company = j.company, 
       temp_lkltn.rig = j.rig, 
       temp_lkltn.rignumber = j.rignumber, 
       temp_lkltn.wellname = j.wellname, 
       temp_lkltn.city = j.city, 
       temp_lkltn.state = j.state 
WHERE  temp_lkltn.lastoflocation = j.jobid 
AND    j.company <> 'Test Company';UPDATE temp_lkltn

Just add a FROM clause with the same table and INNER JOIN with the table you want to. All after the SET clause:
UPDATE temp_lkltn 
SET    temp_lkltn.company = j.company, 
       temp_lkltn.rig = j.rig, 
       temp_lkltn.rignumber = j.rignumber, 
       temp_lkltn.wellname = j.wellname, 
       temp_lkltn.city = j.city, 
       temp_lkltn.state = j.state 
FROM  temp_lkltn
INNER JOIN   job AS j ON     temp_lkltn.lastoflocation = j.jobid 
WHERE  j.company <> 'Test Company'
