Hello,
Is it possible to perform selects in a where clause of a statement?
Given a statement as follows:
SELECT foo.foo_id, foo.name
FROM foo, bar
WHERE foo.bar_id = bar.bar_id
AND bar.name = 'martini';
I'm looking for a way to recast it so that the select and from clauses
refer to a single table and the join referencing the second table
occurs in the where clause. For example, something like this:
SELECT foo.foo_id, foo.name
FROM foo
WHERE (SELECT * FROM foo, bar WHERE ...)
foo.bar_id = bar.bar_id
AND bar.name = 'martini';
I've explored the "where exists" clause, but it's not supported by the
application toolkit I'm using. AFAIK, I've only got access to where ...
Thanks in advance!
Scott
