    While debugging my sql validation on a question, I noticed that if there is an error in the sql validation, then the default is to let the form proceed successfully.

    This is also the way it is documented.

    "The SQL query should return one column called IsValid. If the column returns 0 or False then the validation error message will be thrown, anything else and the user can continue."

    So anything else can for instance be a failure on that validation execution which will let the data be posted.

    IMHO this is the wrong way round. Success should be criteria for user to continue and anything else should generate an error.

    James.

    HI, can you post your SQL validation script here?
    If "IsValid" = 0, that means that it will throw the error; if "IsValid" = 1, then it will pass validation. So in your script, if it's valid, return "IsValid" = 1; else return "IsValid" = 0. If you post your script here, I can check it out and get it to work for you since I've done this numerous times before. -- David

    Here is the script. My comment came not as a result of the script, but when my dnn account did not have rights to execute the procedure the validation anyway passed on the form.

    CREATE PROCEDURE [dbo].[IsValidAccountName]

    @AccountName nvarchar(15)
    AS
    BEGIN
    -- Script called by Manu DNN user registration form question event
    -- to see that the account name is valid and available.
    -- JC 26.3.2010

    SET NOCOUNT ON;

    SELECT CASE
    WHEN @AccountName in (Select AccountName From Registrations) THEN 0
    WHEN LEN(@AccountName) < 5 THEN 0
    WHEN @AccountName LIKE '%[^0-9,a-z]%' THEN 0
    ELSE 1
    END
    AS IsValid

    END

    Hi James,

    Thanks for your feedback. Ultimately (either way) the SQL/Stored Procedure should take into account and trap or catch if an error that might occur. I can understand your cause for concern though and will review this for future updates.
