i was wrong. it doesn't work as a prepared statement nor as a dynamic string
using jdbc.

it works fine if i paste it into psql.

is it possible that a problem with a calculated column and a subselect in
conjunction is a jdbc bug?

when i copy/paste the select stmt into psql, it works. or if i use it
"dynamically". it doesn't work properly when i use it in a prepared
statement -- which is what i am doing.

Subject: column doesn't get calculated

this must be a problem with my sql, but this one has me stumped. the column:
Debit."cumm_dbt_blnce" - Credit."cumm_crd_blnce" in the long sql statement
below comes out as the literal: Debit."cumm_dbt_blnce" -
Credit."cumm_crd_blnce" rather than as the calculated value. WHY!?!?!

this works with simple sql in psql:

select a."field1" - b."field2" from (select field1 as "field1" from
someTable) as a, (select field2 as "field2" from someOtherTable) as b;

but with my more complex sql, it doesn't. it comes out as a literal string.
it's almost like postgresql forgot to process this column.

select
cred_vend_acct_table.num as "num" ,
cred_vend_acct_table.name as "name" ,
abs_vend_acct_type_table.name as "name" ,
Debit."cumm_dbt_blnce" - Credit."cumm_crd_blnce" as "undefined" ,
Debit."cumm_dbt_blnce" as "cumm_dbt_blnce" ,
Credit."cumm_crd_blnce" as "cumm_crd_blnce" ,
cred_vend_acct_table.objid as "__OBJID__" ,
cred_vend_acct_table.clsref as "__CLSREF__"

abs_vend_acct_type_table ,
