ok I have been working on a set of code for archiving information in some of the tables we have and with help got this but now i get two errors and I am not sure why they are errors.
here is the code :
-- archiving the information in the database to speed
-- up the indexing and serching of the table
create proc dbo.ArhicvePunchEvent
(
@CutOffDate datetime=null
)
as
begin
Set nocount on
-- tells the program to check the current time stamp and if less then
-- one year not to archive that data.
if @CutOffDate = DateADD (mm,-12,Current_TimeStamp)
end
-- if the data is older the one year then it moves on
else
begin
if @CutOffDate> DateADD(mm,-12, Current_TimeStamp)
begin
Raiserror('cannot delete order then last 12 months',16,1)
return 1
end
end
-- starts the transaction
begin tran
-- selects all the information in the table for archiving
insert into archive.dbo.punchevents
selet *
from dbo.PUNCHEVENT
where PunchDTM<CutOffDate
-- incase of error well coping info
if @@error <> 70
begin
RollBack Tran
raiserror('error occured while copying data to archive.dbo.punchevent' ,16,1)
return -1
end
-- deletes the old records that have been archived
delete dbo.PUNCHEVENT
where PunchDTM < @CutOffDate
-- incase of error well deleting
if @@error <> 70
begin
rollback tran
raiserror ('error occured while deleting data from dbo.PUNCHEVENT',16,1)
return -1
end
-- begin trans count
if @@TranCount> 0
begin
commit Tran
return 0
end
end
here are the errors i am getting:
Msg 156, Level 15, State 1, Procedure ArhicvePunchEvent, Line 15
Incorrect syntax near the keyword 'else'.
Msg 102, Level 15, State 1, Procedure ArhicvePunchEvent, Line 28
Incorrect syntax near 'selet'.

Off the top of my head the problem is that you ended the if. You need a begin - end block with something in it, or delete the end and the else. like this (see caps.)
if @CutOffDate = DateADD (mm,-12,Current_TimeStamp)
BEGIN
DO SOMETHING INTERESTING
end
-- if the data is older the one year then it moves on
else
begin
if @CutOffDate> DateADD(mm,-12, Current_TimeStamp)
begin
Raiserror('cannot delete order then last 12 months',16,1)
return 1
end
end

Here is another way to do what you are trying to accomplish. It is only a framework, but you should be able to adapt it to your needs.
declare @CutoffDate datetime;
set @CutoffDate = getdate();
declare @PurgeData (
-- columns declared as the exist in the current and archive table
);
begin transaction
begin try
delete from dbo.PUNCHEVENT
output deleted.* into @PurgeData
where
PunchDTM < dateadd(mm, -12, dateadd(mm, datediff(mm, 0, @CutoffDate),0));
insert into archive.dbo.punchevents
select * from @PurgeData;
commit transaction
end try
begin catch
rollback transaction
end catch
