Trigger Inserted and Updated Table

Hi Team,

I have a vendor application where a table with 1 million rows get updated without a where condition (all rows). This table is having an update/insert/delete trigger.

Inside the trigger there is TQL statement as below

 Select @NLCount=Count(*) from deleted where NLstatus=1

The update statment is taking 5 to 6 hours, stuck in the above statement with in the trigger.

can somebody help me please?

if i disable the trigger, the update finish in 7 mins
