As others have explained you cannot change the SQL itself with parameters, you can only change values. However, there should be no reason why you cannot use:

insert into download_log (download_id,status,update_time) values(?,get
+ValueByMeaning(?,?),?)

[download]

and pass 4 parameters. Then you can prepare the SQL outside of the loop.
