Parsing of recursive query returns error "Column does not belong to referenced
table" for source that HAS such column
---------------------------------------------------------------------------------------------------------------------
Key: CORE-4354
URL: http://tracker.firebirdsql.org/browse/CORE-4354
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 3.0 Alpha 2
Reporter: Pavel Zotov
LI-T6.3.0.30889 Firebird 3.0 Alpha 2
with recursive
b as (
select 0 rc
from rdb$database qa
union all
select b.rc+1
from b
join rdb$database q1 on q1.rdb$relation_id*0=b.rc*0
join rdb$database q2 on q2.rdb$relation_id*0=b.rc*0
where b.rc=0
)
select * from b
Result: "Column does not belong to referenced table." (seems that it is 'b.rc'
column that is source of trouble).
Same query in LI-V6.3.3.26744 Firebird 2.5 runs OK and return two rows (0 and
1).
The problem disappears if second join: "join rdb$database q2 on
q2.rdb$relation_id*0=b.rc*0" - is commented out.
