Hi there,

I have this query:

select subquery.inp_alloc_stat2 from
(select P.inp_alloc_stat inp_alloc_stat2 from test.mpi_involved_prof p
group by p.inp_alloc_stat) subquery
LEFT OUTER JOIN (select g.gen_prefix gen_prefix2, g.gen_code gen_code2, g.gen_desc gen_desc2 from test.lup_generic) g
on subquery.inp_alloc_stat2 = g.gen_code2

I used a left outer join because I want to preserve all records from table p PLUS matching records from g. I just want to check to see if the syntax is correct.

Syntactically, it appears correct. However, there is no real need to select from test.lup_generic and make it a derived table, you can simply join to the table.

you're not selecting any fields from g in the select list then why do you need LEFT JOIN part?
