I’m using SQL Server 2008, I’m importing the data using the Import Wizard.

I have data from an excel file like the following…

SessionID       Email     SubmitTime      Question1     Question2    Question3 
----------      -----     -----------     ---------     ---------    ----------
54535212        a@b.com   12/21/2011      Yes           No           Yes
54532342        c@d.com   12/22/2011      Yes           Yes          Yes
54535288        e@f.com   12/23/2011      No            No           Yes
54532399        g@h.com   12/24/2011      No            Yes          Yes

Now I want to store it in my database so I can easily access the data. I’m thinking I should make a Users Table, Questions Table, Answers Table, Submitted Table. For my purposes the Submitted Table can become a column for the User’s Table. 

User
`Email`
`Submitted`
`SessionID`

Question
`Question1`
`Question2`
`Question3`

Answer
`Email`
`Question`
`Answer`

How can I populate the Answer table with a query from the Excel document? Or the initial table created from the Excel document on import? This seems like an easy problem but the solution is for some reason eluding me. Thanks for any help!

    Your data structure’s a bit screwed up. If you have three columns for Question1 through Question3, then you’d want a SurveyID column or something of the sort to identify the unique combinations. Then, your answer table would have UserID, SurveyID, Answer1, Answer2, and Answer3 columns.

    If your Question table has one Question column and a QuestionID column (hopefully an identity column so it auto-increments, then you’d do something like this to populate the Answer table from your Import table:

    insert into answer (userid, questionid, answer)
select
    u.userid,
    q.questionid,
    case
        when q.question = 'Question1' then i.question1
        when q.question = 'Question2' then i.question2
        when q.question = 'Question3' then i.question3
        else null
    end as answer
from
    import i
    inner join users u on
        i.email = u.email
    cross join question q
