I was again wrong, but also right. It was not a PRIMARY index, but an
UNIQUE index:
sqlite> .schema weights
CREATE TABLE weights (
id INTEGER PRIMARY KEY,
categoryID INTEGER NOT NULL,
measureDate DATE DEFAULT (DATE('now')),
weight FLOAT NOT NULL,
fat FLOAT,
water FLOAT,
muscle FLOAT,
UNIQUE (
categoryID,
measureDate
)
);
sqlite> .indices
sqlite> .indices weights
sqlite_autoindex_weights_1
