SP Catch Error

Hi,

I have the following stored procedure which is added to the windows scheduler. When it is run I'm getting an "Invalid use of null error", therefore I need to capture and any errors but I'm not sure how to do this. Can someone help?
Thanks.


Code:

CREATE PROCEDURE [dbo].[usp_Reminders] AS

DECLARE @ReminderSent datetime
DECLARE @getRecords CURSOR
DECLARE @err int

SELECT E.[RL Staff No], E.Forename, E.Surname, C.CourseName, V.CourseDate , E.Email, V.ReminderSent
FROM empdetails.dbo.v_Employee E
INNER JOIN Validation V ON E.[RL Staff No] = V.[RL Staff No]
INNER JOIN empdetails.dbo.v_Course C ON V.CourseCode = C.CourseCode
WHERE V.Completed Is Null AND V.ReminderSent Is Null AND V.CourseDate <= dateadd(dd, -3, getdate())
order by e.[rl staff no]

SET @getRecords = CURSOR FOR

SELECT V.ReminderSent
FROM empdetails.dbo.v_Employee E
INNER JOIN Validation V ON E.[RL Staff No] = V.[RL Staff No]
INNER JOIN empdetails.dbo.v_Course C ON V.CourseCode = C.CourseCode
WHERE V.Completed IS NULL AND V.ReminderSent IS NULL AND V.CourseDate <= dateadd(dd, -3, getdate())
ORDER BY e.[rl staff no]

OPEN @getRecords
FETCH NEXT FROM @getRecords INTO @ReminderSent
WHILE @@FETCH_STATUS= 0
BEGIN
UPDATE Validation
SET ReminderSent = GetDate()
WHERE CURRENT OF @getRecords
FETCH NEXT FROM @getRecords INTO @ReminderSent
END

CLOSE @getRecords
DEALLOCATE @getRecords
GO
