## Summary
<!--Explain briefly what goes wrong and explain why you believe this is a bug and not the intended behavior of SQLite (if it is not a crash).-->
The queries added new columns with 123. Probably "INTERSECT" is wrong. It is a logic bug because the output is different
## Minimized query
```sql
ATTACH DATABASE ':memory:' AS aux12;
PRAGMA fullfsync;
PRAGMA automatic_index = ON;
PRAGMA wal_checkpoint;
.tables
CREATE TABLE t1(c1);
INSERT INTO t1 VALUES(if(2147483647, 12, 0, 12, 0, 12, 12)),(123),(1234),(NULL),('abc');
CREATE TABLE "t2"(c2);
INSERT INTO t2 VALUES(44),(55),(123);
CREATE TABLE t3(c3,c4);
INSERT INTO t3 VALUES(66,1),(123,2),(77,3);
CREATE VIEW t4 AS SELECT c3 FROM t3;
CREATE VIEW t5 AS SELECT c3 FROM t3 ORDER BY c4;
SELECT * FROM t1, t2 WHERE c1=(SELECT 123 INTERSECT SELECT c2 FROM t4) AND c1=123;
SELECT * FROM t1, t2 WHERE c1=(SELECT 123 INTERSECT SELECT c2 FROM t5) AND c1=123;
SELECT COUNT(*) FROM t1;
ANALYZE;
INSERT OR IGNORE INTO t1 VALUES ('');
SELECT * FROM t1 WHERE c1 = (SELECT SUM(c1) FROM t1);
INSERT INTO t2 DEFAULT VALUES;
SELECT COUNT(*) FROM t1;
ANALYZE;
WITH RECURSIVE cnt(x) AS (VALUES(1) UNION ALL SELECT x+1 FROM cnt WHERE x<63) SELECT * FROM cnt;
ANALYZE;
SELECT COUNT(*) FROM t3;
ANALYZE t2;
ANALYZE;
CREATE TEMP VIEW IF NOT EXISTS v_t1_9829 AS SELECT c1 FROM t1;
WITH cte AS (SELECT c3, LEAD(c3) OVER (ORDER BY c3) AS nxt FROM t3) SELECT * FROM cte;
SELECT * FROM t1 NATURAL JOIN t1;
REINDEX;
PRAGMA foreign_keys = YES;
VACUUM main;
CREATE TRIGGER IF NOT EXISTS trg_t1_6595 BEFORE UPDATE OF c1 ON t1 FOR EACH ROW BEGIN SELECT RAISE(IGNORE); END;
DETACH DATABASE aux12;
INSERT INTO t1 DEFAULT VALUES;
