## 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).-->**No review yet**

|
## Minimized query
|
|
|
|
```sql
|
|
PRAGMA empty_result_callbacks = TRUE;
|
|
CREATE TABLE t1(a INT, b INT);
|
|
CREATE TABLE t2(c INT, d INT);
|
|
CREATE TABLE t3(e TEXT, f TEXT);
|
|
INSERT INTO t1 VALUES(1, 1);
|
|
INSERT INTO t2 VALUES(1, 2);
|
|
INSERT INTO t3 VALUES('abc', 'def');
|
|
SELECT * FROM t1, t2 LEFT JOIN t3 ON (t2.d=1) WHERE t2.c = +t1.a;
|
|
SELECT * FROM t1 LEFT JOIN t2 ON (t2.c=+t1.a) LEFT JOIN t3 ON (t2.d IS NULL);
|
|
|
|
SELECT * FROM t2;
|
|
SELECT MIN(b) OVER (PARTITION BY b ORDER BY b RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING EXCLUDE NO OTHERS) FROM t1;
