## 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
|
|
BEGIN EXCLUSIVE;
|
|
.eqp full
|
|
.vfsinfo
|
|
creATE VIRTUAL TABLE t0 USING fts3("x", "y", "z");
|
|
DROP TABLE t0;
|
|
PRAGMA automatic_index = OFF;
|
|
CREATE TABLE T (
|
|
a TEXT,
|
|
b INTEGER,
|
|
c REAL
|
|
);
|
|
INSERT INTO T VALUES ('a',1,2.0), ('a',2,-3.0), ('b',1,4.5);
|
|
SELECT a,b,c,
|
|
SUM(c) OVER (
|
|
PARTITION BY a
|
|
ORDER BY b
|
|
) AS d
|
|
FROM T;
|
|
SELECT COUNT(*) OVER (PARTITION BY c ORDER BY c) FROM T;
|
|
SELECT * FROM (SELECT * FROM (SELECT * FROM T) AS inner1) AS inner2;
|
|
END;
|
|
```
|
|
|
|
## Actual output
|
|
|
|
```sql
|
|
vfs.zName = "unix"
|
|
vfs.iVersion = 3
|
|
vfs.szOsFile = 120
|
|
vfs.mxPathname = 512
