I'm using a Typed DataSet with an Insert statement; I have a table that has a smalldatetime field defined to accept null values. When I insert from a .NET 2.0 FormView, I get a "SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM."
Now, I've read this post, and the parameter as sent to the class constructor is defined as
global::System.Nullable<global::System.DateTime> DoB
So, it looks like it should accept a Nullable obj. Additionally, the generated code is testing the value sent.
if ((DoB.HasValue == true)) {
command.Parameters[6].Value = ((System.DateTime)(DoB.Value));
}
else {
command.Parameters[6].Value = global::System.DBNull.Value;
}
Specifically, the error is occurring when generated SqlClient.SqlCommand.ExecuteScalar() runs:
try {
returnValue = command.ExecuteScalar();
}
So, I guess my question is: how do I use a Typed DataSet to set a blank value (passed from a FormView on CommandName=Insert) to a null in a database?
