I would like to know how this query would be written if no joins were used. I been trying to figure it out for cases where joins aren’t viable or can’t be used(aren’t available).

SELECT     * FROM (     table1 INNER JOIN     table2 ON     table1.id = table2.id ) INNER JOIN     table3 ON (     table1.id2 = table3.id2 ) AND (     table1.id3 = table3.id3 ) WHERE     table1.id = 1

The reason I can’t use joins is because the application uses HQL as opposed to standard SQL and HQL makes joins incredibly difficult to do.
