SQL query and Export Metadata

Hi all,
I would like to have your input for this part of my script.
I am trying to set up an SQL query box in my tool that will allow users to to select and query from the fields obtained in the input feature layer (Input_Poly_Feature_Layer). The only problem: it seems like there is no way to display the fields in the Query builder box. Do you guys know if there is anyway to make the fields show up?

Last thing that I will intend to do is:
Each time the script is ran, I would like to save a copy of all the Metadata (All steps used for this) as a CVS file or text file? Do you have any hints or ideas on how to do this?

Thanks,
Alex
