my question is how to limit update to one row at a time when i have no creteria
my problem is like that i have a table called workq
on this table one ore more work station can read data from
but if one workstation reads the data the outher one must not read the same data
i dont want to use locking becouse that slow the database so what i was thinking was first update a status on the row
and then read it
so it will look something like that:
NOW UPDATE ONLY ONE ROW
Update workq set status = 1
SELECT message TOP 1 from workq where id = @@IDENTITY
