> my industry codes are one on single column, do you mean that I need to create one dummy variable for each industry code first and then I can use normal regression ?


Pre-Stata 11, as you have indicated, 

tab industry, gen(inc)

will create inc1, inc2…

presuming you don't have such variables already. If you do, change the stub.

Include all but one of them in the model; e.g. inc2-inc15  or inc1-inc14.
