  Test Function:
  var i = 1
  // infinite loop
  for {
	for _, sql := range TestSQLs {
		go ast.QueryType(sql)
	}
	i = i + 1
	fmt.Println("loop: ", i)

  GRANT SELECT ON *.* to user@'host'
  REVOKE INSERT ON *.* FROM 'jeffrey'@'localhost';

  drop table tb
  drop database db
  create database db

  echo "select * from tb" | soar -report-type query-type
