Since you havent mentioned the DBMS in which you are facing the issue, I have assumed it to be POSTGRES

SELECT to_regclass('foo');

In Postgres 9.3 or older use a cast to regclass:

SELECT 'foo'::regclass;

If at all your requirement is MYSql then use the below statement:

You can use show tables like this to see if a single table exists:

mysql> show tables like "test1";
