Ok, so my schema is this:
Table: Timesheet_Hours
Columns:
This is an extremely simplified version of the table, but it will serve for the purposes of this explaination. Assume that a person can only ever have one timesheet record.
What I'm trying to do is add records to another table, called WorkLog. Each record here has a time associated with it. When that table is updated, I want to update Timesheet_Hours as well.
Before I update Timesheet_Hours, I want to check first that the relevant Timesheets haven't already been posted, and then I want to check if there is in fact a record to update in the first place.
The first part of the if statement, which checks to see that the timesheets haven't already been posted, works fine. The problem is the second part. It is checking to see that the record it is going to update already exists. The issue is that it always raises an error.
NB: The code below is extracted from a stored procedure run by the update, insert and delete triggers on the WorkLog table. @PersonID is one of the parameters to that table. The stored procedure works fine if I comment out the second part of this statement.
IF EXISTS
(
SELECT 1
FROM Timesheet_Hours
WHERE Posted_Flag = 1
AND Staff_Id = @PersonID
)
BEGIN
RAISERROR('Timesheets have already been posted!', 16, 1)
ROLLBACK TRAN
END
ELSE
IF NOT EXISTS
(
SELECT 1
FROM Timesheet_Hours
WHERE Staff_Id = @PersonID
)
BEGIN
RAISERROR('Default list has not been loaded!', 16, 1)
ROLLBACK TRAN
END

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.
set nocount on
create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)
insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)
declare @PersonID int
set @PersonID = 1
IF EXISTS
(
SELECT 1
FROM Timesheet_Hours
WHERE Posted_Flag = 1
AND Staff_Id = @PersonID
)
BEGIN
RAISERROR('Timesheets have already been posted!', 16, 1)
ROLLBACK TRAN
END
ELSE
IF NOT EXISTS
(
SELECT 1
FROM Timesheet_Hours
WHERE Staff_Id = @PersonID
)
BEGIN
RAISERROR('Default list has not been loaded!', 16, 1)
ROLLBACK TRAN
END
ELSE
print 'No problems here'
drop table Timesheet_Hours
