Multipls cursors help

Hello,
I am trying to create multiple cursors and update 2 separate tables. But the
data tables seem to be locking after I run them. Is my logic off? My code is
below -
set xact_abort on
declare @.user_id int, @.topic_name varchar(20), @.key_seq_num int
declare GetUserID cursor for
select [user_id] from users where [user_id] not in (select [user_id] from
userdata)
open GetUserID
fetch next from GetUserID into @.user_id
while @.@.fetch_status = 0
begin
begin tran
--new cursor
declare GetUserData cursor for
select topic_name from userdata where [user_id] = 327
open GetUserData
fetch next from GetUserData into @.topic_name
while @.@.fetch_status = 0
begin
begin tran
--new cursor
declare GetNextID cursor for
select key_seq_num from nextkey where key_name = 'userdata_user_data_id'
open GetNextID
fetch next from GetNextID into @.key_seq_num
while @.@.fetch_status = 0
begin
begin tran
insert into UserData(user_data_id, [user_id], topic_name, update_date,
update_user, create_date, create_user)
select @.key_seq_num, @.user_id, @.topic_name, getdate(), 'Default',
getdate(), 'Default'
update nextkey set key_seq_num = @.key_seq_num + 1
from nextkey where key_name = 'userdata_user_data_id'
commit tran
print @.key_seq_num
fetch next from GetNextID into @.key_seq_num
end
close GetNextID
deallocate GetNextID
fetch next from GetUserData into @.topic_name
end
close GetUserData
deallocate GetUserData
fetch next from GetUserID into @.user_id
end
close GetUserID
deallocate GetUserIDAnil,
Can you explain what are you trying to accomplish?

2
and 3 and update them into a table. Cursor 3 has an id that needs to be
incremented each time as it is not an auto number. The way I have laid out m
y
cursors, is that the correct way?
Thanks.

Can you explain it without referencing the cursors?

Looks like the tables which you are accessing is getting locked since you do
all your stuff within a transaction.
You can do 2 things to see if the issue is happening because of a lock
1. Remove all transaction (begin/commit tran) and see if your code actually
works.
2. If your code works after step 1 then use WITH (NOLOCK) clause in your
select statements.
Regards,
Joe.
