What exactly the purpose of select count(1)? I am debugging a code that has that select statement. I know that select count returns the total of the values that are stored in the column, and I've used count before (select count(col1)), but I have never used count(1).
As far as I know Count(1) does the same thing as count(*), but some people believe count(1) is better from the performance point of view especially for tables containing large data volumes and having many columns.
Search for any usage of the variable v1, if it is not used then the select is not needed, but since it is being put into a string, I suspect that someone is putting out a report of some kind at the end. Maybe a comparison of the count of col1 = var2 before and after the procedure (just a guess)
