Minimized query

BEGIN DEFERRED;
CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c INT, d INT);
INSERT INTO t1 VALUES (NULL, '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
DROP TABLE IF EXISTS t1;
DROP TABLE IF EXISTS t2;
CREATE TABLE t1(x);
INSERT INTO t1 VALUES(-2147483649);
CREATE TABLE t2(y,z);
INSERT INTO t2 VALUES(2,3);
CREATE INDEX t2y ON t2(y);
SELECT * FROM t1,(SELECT * FROM t2 WHERE y=2 ORDER BY y,z);

SELECT GROUP_CONCAT(x, '.') OVER (PARTITION BY x ORDER BY x ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) FROM t1;
INSERT OR ABORT INTO t2 VALUES (0, 'x');
END;
DELETE FROM t1 WHERE x > (SELECT AVG(x) FROM t1);

Actual output

CREATE TABLE "t2"("b","c","_ROWID_",PRIMARY KEY("b","c","_ROWID_"))WITHOUT ROWID;
WARNING: writing to an imposter table will corrupt the "t1bc" index!
