Why would you switch to back_tick quoting, even when option ANSI_QUOTES is
on? Why would you want to try with a configuration different from option set by
user?
also, sql.contains("`") may not work, if the sql string contains ` as a
character in a string literal. I could not see how this block of code will work
for such case.
