Minimized query

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 T (
  a INTEGER,
  b TEXT,
  c REAL
);
INSERT INTO T VALUES (1,'a',1.25), (2,'b',-3.5), (3,'c',9e999);
WITH d AS (SELECT * FROM T) SELECT * FROM d WHERE c > 0;
CREATE  INDEX IF NOT EXISTS idx_t1_1739 ON t1(lower(d)) WHERE d > 0;

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!
