如何知道哪个外键约束在SQLite中失败？

如何解决如何知道哪个外键约束在SQLite中失败？

问题很简单。当外键约束在sqlite中失败时，我不知道如何确定哪个失败。

PRAGMA foreign_keys=1;
DROP TABLE IF EXISTS TEMP.child;
DROP TABLE IF EXISTS TEMP.parent;

CREATE TEMP TABLE parent (
    id INTEGER PRIMARY KEY
);

CREATE TEMP TABLE child (
    id INTEGER PRIMARY KEY,parent_id1 INTEGER NOT NULL,parent_id2 INTEGER NOT NULL,name TEXT NOT NULL,CONSTRAINT no_a CHECK (name IS NOT 'a'),CONSTRAINT fk1 FOREIGN KEY (parent_id1) REFERENCES parent (id),CONSTRAINT fk2 FOREIGN KEY (parent_id2) REFERENCES parent (id)
);

在每个查询下面，我将粘贴错误/结果。您将看到错误中显示的命名约束no_a，但外键则没有。

INSERT INTO TEMP.child VALUES (1,'a');

INSERT INTO TEMP.child VALUES (1,'b');
