    Hi all,

    I have a table called ContestOption.

    I have 3 fields in it..

    namely,

    1.ContestOptionID

    2.ContestID

    3.ContestOption

    I have a method like this,

    public void CreateOptions(long ContestID, string Options,string CorrectOpt)

    {

    int status = 0;

    long CorrectOptID = -1;

    Database db = DatabaseFactory.CreateDatabase();

    SqlCommand cmdSQL = new SqlCommand("");

    cmdSQL.Parameters.AddWithValue("@ContestId", ContestID);

    cmdSQL.Parameters.AddWithValue("@Options", Options);

    cmdSQL.Parameters.AddWithValue("@CorrectOption", CorrectOpt);

    SqlParameter output = new SqlParameter("@CorrectOptID", SqlDbType.BigInt);

    output.Direction = ParameterDirection.Output;

    cmdSQL.Parameters.Add(output);

    cmdSQL.CommandType = CommandType.StoredProcedure;

    try

    {

    status = db.ExecuteNonQuery(cmdSQL);

    CorrectOptID = Convert.ToInt64(cmdSQL.Parameters["@CorrectOptID"].Value.ToString());

    }

    catch (Exception ex)

    {

    CommonUtilities.WriteErrorInXML(ex.Message);

    }

    }

    Now my problem is that i don know how to write the stored procedure so that the contest options are split and stored row by row and the correct option is returned.

    In the method above,

    String options is concatinated using many strings,

    like,

    String1|String2|string3|string4 and so on...

    So in the SP itself it should be split and inserted into that table..

    Plz Plz Help me.

    search the "Scripts" section here on SSC for "Split Function"

    there are a lot of great contributions there;

    they typically expect a varchar string and a delimiter to split them by:

    for example:

    select stuff from yourtable where somevalue in dbo.Split(@String,'|')

    that will do exactly what you are looking for;

    I would suggest using one based on a Tally table, there's a great article by Jeff Moden here that uses a Tally table to split 1,2 and 3 dimential arrays from your passed in varchar string:

    THe code below is doing what exactly you want , It is taking a comma separated string and then filling each value in the temporary table.you can repalce the comma by '|' and temporart table by your table name and whatever fields you want .

    hope it help;

    DECLARE @SQL varchar(1600)

    CREATE TABLE #TempList

    (

    tankAltName varchar(9)

    )

    DECLARE @tankalt varchar(9), @Position int

    SET @tankAltName = LTRIM(RTRIM(@TankAltName))+ ','

    SET @Position = CHARINDEX(',', @tankAltname, 1)

    IF REPLACE(@tankAltName, ',', '') ''

    BEGIN

    WHILE @Position > 0

    BEGIN

    SET @tankAlt = LTRIM(RTRIM(LEFT(@TankALtName, @Position - 1)))

    IF @TankALt ''

    BEGIN

    INSERT INTO #TempList (tankAltName) VALUES (CAST(@TankALt AS varchar))

    END

    SET @TankAltName = RIGHT(@TankAltName, LEN(@TankALtName) - @Position)

    SET @Position = CHARINDEX(',', @TankAltName, 1)

    END

    END
