Allow referencing cursors as record variables in PSQL
-----------------------------------------------------
Key: CORE-4403
URL: http://tracker.firebirdsql.org/browse/CORE-4403
Project: Firebird Core
Issue Type: Improvement
Components: Engine
Reporter: Dmitry Yemanov
Priority: Minor
Either explicit (DECLARE AS CURSOR) or implicit (FOR SELECT) PSQL cursors could
make their current record available via the cursor name similar to OLD/NEW
trigger contexts, thus making the INTO clause optional. In FOR SELECT loops, it
requires AS CURSOR clause to be specified. For example:
for
select rdb$relation_id as id, rdb$relation_name as name
from rdb$relations
where rdb$view_blr is null
as cursor tables
do begin
out_id = tables.id;
out_name = tables.name;
suspend;
end
To avoid ambiguities, the colon prefix could be used.
