Question

I have a temp table (question_desc, ans1, ans2, ans3, ans4, correct_ans, marks) with say 10 entries.

From this table I have to insert values in two other tables:

questions (q_id(auto-generated), que_desc, marks)

answers (ans_id(auto_generated), q_id(FK), ans_desc, istrue)

For each insert in questions table there should be four inserts in answers table and istrue bit will be set 1 for correct answer.

Like for question 1 with corr_ans 1, four entries will be

(1,1,djhjfj,1),
(2,1,hdjfsh,0),
(3,1,hsssh,0),
(4,1,jfsh,0)

After one row is inserted in questions table I need to fetch the q_id and use it while inserting 4 answer records.

I tried using insert trigger but it doesn’t work as it is statement level trigger, not row level. I am using SQL 2005. Please help.

Here is the basic idea, try to incorporate this into the rest of your app.

CREATE PROCEDURE dbo.funnyInsert(
@question_desc varchar(100)
,@ans1 varchar(100)
,@ans2 varchar(100)
,@ans3 varchar(100)
,@ans4 varchar(100)
,@corect_ans varchar(100)
,@mark numeric(4,1)
)
AS
BEGIN
    DECLARE @lastID int

    INSERT INTO dbo.questions(que_desc, mark)
        VALUES(@question_desc, @mark);

    SET @lastID = IDENT_CURRENT('dbo.questions')

    INSERT INTO dbo.answers(q_id,ans_desc, isTrue)
        VALUES(@lastID, @ans1,
        CASE WHEN @ans1 = @corect_ans THEN 1 ELSE 0 END);

    INSERT INTO dbo.answers(q_id,ans_desc, isTrue)
        VALUES(@lastID, @ans2,
        CASE WHEN @ans2 = @corect_ans THEN 1 ELSE 0 END);

    INSERT INTO dbo.answers(q_id,ans_desc, isTrue)
        VALUES(@lastID, @ans3,
        CASE WHEN @ans3 = @corect_ans THEN 1 ELSE 0 END);

    INSERT INTO dbo.answers(q_id,ans_desc, isTrue)
        VALUES(@lastID, @ans4,
        CASE WHEN @ans4 = @corect_ans THEN 1 ELSE 0 END);

END
