Question

I have the following database:

CREATE TABLE QUESTION (
    QUES_ID  INTEGER AUTO INCREMENT,
    TOPIC_ID INTEGER NOT NULL,
    QUESTION_DESC TEXT NOT NULL,
    CHOICE_A TEXT,
    CHOICE_B TEXT,
    CHOICE_C TEXT,
    CHOICE_D TEXT,
    PRIMARY KEY (QUES_ID,TOPIC_ID),
    FOREIGN KEY (TOPIC_ID) REFERENCES TOPIC(TOPIC_ID)
);

When I insert info like that…

INSERT INTO 
    QUESTION (TOPIC_ID,QUESTION_DESC,CHOICE_A,CHOICE_B,CHOICE_C,CHOICE_D)
VALUES 
    (1,'Blue or blue?','red?','yellow?','black?','yellow again?');

I get the following results, the ques_id doesn’t get assigned!

QUES_ID     TOPIC_ID   QUESTION_DESC  CHOICE_A  CHOICE_B  CHOICE_C  CHOICE_D     
----------  ---------  -------------  --------- --------- --------- -------------
             1         Blue or blue?  red?      yellow?   black?    yellow again?

Answer 1

Per the SQLite FAQ:

A column declared INTEGER PRIMARY KEY will autoincrement.

So your DDL statement should look more like:

CREATE TABLE QUESTION (
    QUES_ID INTEGER PRIMARY KEY,
    TOPIC_ID INTEGER NOT NULL,
    QUESTION_DESC TEXT NOT NULL,
    CHOICE_A TEXT,
    CHOICE_B TEXT,
    CHOICE_C TEXT,
    CHOICE_D TEXT,
    -- the primary key must be QUES_ID 
    -- if you want it to auto-increment
    -- so if you really want you can add 
    -- a unique constraint here
    CONSTRAINT qt UNIQUE (QUES_ID, TOPIC_ID),
    FOREIGN KEY (TOPIC_ID) REFERENCES TOPIC (TOPIC_ID)
);
