## 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 writable_schema = 0;
|
|
ATTACH DATABASE (':memory:' || '') AS aux12;
|
|
PRAGMA checkpoint_fullsync = OFF;
|
|
CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c INT, d INT);
|
|
INSERT INTO t1 VALUES (1, 'Wernher', 10, 100);
|
|
INSERT INTO t1 VALUES (2, 'von', 20, 200);
|
|
INSERT INTO t1 VALUES (3, 'Braun', 30, 300);
|
|
|
|
CREATE INDEX t1bc ON t1(b, c);
|
|
|
|
PRAGMA writable_schema = ON;
|
|
|
|
.imposter t1bc t2
|
|
|
|
SELECT * FROM t2;
|
|
|
|
SELECT b, c FROM t1 ORDER BY b, c;
|
|
|
|
.quit
|
|
CREATE TABLE t1(x);
|
|
INSERT INTO t1 VALUES(99);
|
|
SELECT sum((SELECT 1 FROM (SELECT 2 WHERE x IS NULL) WHERE 0)) FROM t1;
|
|
DELETE FROM t1 WHERE x IS NULL;
|
|
INSERT INTO t1 VALUES (NULL);
|
|
SELECT COUNT(*) FROM t1;
|
|
DETACH DATABASE aux12;
|
|
INSERT INTO t1 VALUES (NULL);
|
|
UPDATE t1 SET x = CURRENT_TIMESTAMP WHERE x IS NOT NULL RETURNING *;
|
|
ALTER TABLE t1 ADD COLUMN extra_5709 FLOAT;
|
|
SELECT COUNT(*) FILTER (WHERE x IS NOT NULL), SUM(rowid) FILTER (WHERE x > 0), COUNT(*) FILTER (WHERE 1=0), COUNT(*) FILTER (WHERE 1=1), COUNT(*) FILTER (WHERE NULL), AVG(x) FILTER (WHERE x > 0 AND x < 100), COUNT(*) FILTER (WHERE typeof(x) = "text") FROM t1;
|
|
CREATE INDEX IF NOT EXISTS idx_t1_6962 ON t1(x COLLATE NOCASE) WHERE x > 0;
|
|
SELECT COUNT(*) FILTER (WHERE x IS NOT NULL), SUM(rowid) FILTER (WHERE x > 0), COUNT(*) FILTER (WHERE 1=0), COUNT(*) FILTER (WHERE 1=1), COUNT(*) FILTER (WHERE NULL), AVG(x) FILTER (WHERE x > 0 AND x < 100), COUNT(*) FILTER (WHERE typeof(x) = "text") FROM t1;
|
|
ALTER TABLE t1 ADD COLUMN extra_9323 NATIVE CHARACTER(70)NVARCHAR(100) COLLATE RTRIM;
|
|
```
|
|
|
|
## Actual output
|
|
|
|
```sql
|
|
CREATE TABLE "t2"("b","c","_ROWID_",PRIMARY KEY("b","c","_ROWID_"))WITHOUT ROWID;
|
|
WARNING: writing to an imposter table will corrupt the "t1bc" index!
