SQL Temp Tables Dynamic Columns

I am creating a temp table with one column.

create table #temp(JobID int);

Then I dynamically add more columns to the temp table.

SET     @script = 'ALTER TABLE #temp ADD '

Select @script = @script + QUOTENAME(job) + ' INT DEFAULT 0 WITH VALUES,'
from Jobs

Now my table looks like this.

JobID  Station1 Station2 Station3 Station4
3000         0              0              0             0
3002         0              0              0             0
3152         0              0              0             0
4125         0              0              0             0

Now I need to Update the dynamic columns (Station1 Station2 Station3 Station4)
for each JobID to get results like this.

JobID  Station1 Station2 Station3 Station4
3000         52             48            55           60
3002         62             59            63           55
3152         79             71            58           60
4125         21             28            34          19

Any help would be helpful.

Thanks
