Minimized query

CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c INT, d INT);
INSERT INTO t1 VALUES (if(-1, 1, 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
INSERT INTO t1 DEFAULT VALUES;
SELECT COUNT(a) FROM t1;
SELECT COUNT(*) FILTER (WHERE b IS NOT NULL), SUM(rowid) FILTER (WHERE b > 0), COUNT(*) FILTER (WHERE 1=0), COUNT(*) FILTER (WHERE 1=1), COUNT(*) FILTER (WHERE NULL), AVG(b) FILTER (WHERE b > 0 AND b < 100), COUNT(*) FILTER (WHERE typeof(b) = "text") FROM t1;
SELECT GROUP_CONCAT(a, '.') FILTER (WHERE a IS NOT NULL) OVER (ORDER BY a RANGE BETWEEN 1 PRECEDING AND 1 FOLLOWING) 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!
