Question

I have the following SQL Server error in ASP.net C#:

The conversion of a varchar data type to a datetime data type resulted
in an out-of-range value.

My SQL query is:

string query = @"update Conference set Conference_name='" 
    + name + "',AIMS='" + AIMS + "',Scope='" + scope 
    + "',Submission_Deadline='" + submissionDay 
    + "',Notification_Deadline='" + notificationDay 
    + "',Camera_Ready_submission='" + cameraReadyDay 
    + "',Early_authors_registration='" + earlyAuthorsDay 
    + "',Start_Date='" + startDay + "',End_Date='" + endDay 
    + "',Location='" + location 
    + "' where Conference_ID= '" + id+"'";

Answer 1

Perhaps it is time to add some validation. May I suggest the RangeValidator, with type set to Date?
