Multiple table select, but still returning row if no record exists in second table?

I'm using mysql. Is there any way to do a multiple-table select, but still return the results from table 1 if there are no matching rows in table 2? Something like "select table1.something,table2.something as something2 from table1,table2 where table1.table2id = table2.id" will only return the data from table1 if a row with the id in table1.table2id exists in table2. -- The above message is encrypted with double rot13 encoding.
