------------------------------------------
Summary: Calcite engine. Query plan can't be planned if correlated
variable used in both filter and project
Key: IGNITE-15984
URL: https://issues.apache.org/jira/browse/IGNITE-15984
Project: Ignite
Issue Type: Bug
Reporter: Aleksey Plekhanov
For example, query:
{noformat}
CREATE TABLE test(i INT)
SELECT (SELECT t0.i FROM test t1 WHERE t1.i = t0.i) FROM test t0
{noformat}
Fails, but if we make project uncorrelated:
{noformat}
SELECT (SELECT t1.i FROM test t1 WHERE t1.i = t0.i) FROM test t0
{noformat}
Or remove correlated filter:
{noformat}
SELECT (SELECT t0.i FROM test t1) FROM test t0
{noformat}
Query executes successfully.
