Hi Alexey, Did you try running MySQL's test? It needs some adjustments to run, but these can be done. I've found four crashes: --echo # --echo # Bug#26500384: ASSERT FAILURE IN QUERY WITH WINDOW FUNCTION AND --echo # JSON_TABLE --echo # --disable_parsing ## psergey: crash! CREATE TABLE t (x INT); INSERT INTO t VALUES (1), (2), (3); --error ER_BAD_FIELD_ERROR SELECT MAX(t.x) OVER () m, jt.* FROM t, JSON_TABLE(JSON_ARRAY(m), '$[*]' COLUMNS (i INT PATH '$')) jt; DROP TABLE t; --enable_parsing --echo # --echo # Bug#26679671: SIG 11 IN JSON_BINARY::PARSE_BINARY() --echo # CREATE TABLE t1(id INT, f1 JSON); INSERT INTO t1 VALUES (1, '{\"1\": 1}'), (2, '{\"1\": 2}'), (3, '{\"1\": 3}'), (4, '{\"1\": 4}'), (5, '{\"1\": 5}'), (6, '{\"1\": 6}'); ANALYZE TABLE t1; # ... SELECT * FROM t1 WHERE id IN (SELECT id FROM t1 as tt2, JSON_TABLE(f1, "$" COLUMNS (jf FOR ORDINALITY)) AS tbl); EXPLAIN SELECT * FROM t1 WHERE id IN (SELECT id FROM t1 as tt2, JSON_TABLE(f1, "$" COLUMNS (jf FOR ORDINALITY)) AS tbl); --echo # --echo # Bug#26500384: ASSERT FAILURE IN QUERY WITH WINDOW FUNCTION AND --echo # JSON_TABLE --echo # --disable_parsing ## psergey: crash! CREATE TABLE t (x INT); INSERT INTO t VALUES (1), (2), (3); --error ER_BAD_FIELD_ERROR SELECT MAX(t.x) OVER () m, jt.* FROM t, JSON_TABLE(JSON_ARRAY(m), '$[*]' COLUMNS (i INT PATH '$')) jt; DROP TABLE t; --enable_parsing There are some interesting non-crash issues, too.
