Project: Firebird Core
Issue Type: Bug

(
P1 integer
)
returns

select p11 from testproc(:p1) into p11;
suspend;
end
2. Create procedure TESTPROC2 which uses TESTPROC
create or alter procedure TESTPROC2
(
P1 integer
)
returns
(
P11 integer
)
as
begin
select p11 from testproc(:p1) into p11;
suspend;
end
3. Add input parameter P2 to original TESTPROC and pass P2 in recursive call of
TESTPROC
create or alter procedure TESTPROC
(
P1 integer,
P2 integer = 0
)
returns
(
P11 integer
)
as
begin
select p11 from testproc(:p1, :p2) into p11;
suspend;
end
