  if without_prepared_statement?(binds)
    log(sql, name) { @connection.execute_insert(sql) }
  else

      @connection.execute_insert(sql, binds)
    end
  end
end

#exec_query(sql, name = nil, binds = NO_BINDS, prepare: false) ⇒ Object

It appears that at this point (AR 5.0) "prepare" should only ever be true if prepared statements are enabled
