| I’m starting to get some optimistic column locking failures during background db processing soI’m trying to grasp conditions under which I don’t need to lock a column (i.e. put the little lock symbol in EOModeler)
If I have a column in a table that I know is not updated (i.e. changed) by any client except form my personal administrative page, can I get away without locking that column? On unlocked columns is there any where clause checks such as shown below before that column is updated? If not, this should stop the locking errors, right? Any other dangers with this?
update Person set FirstName = 'Robert' where PersonID = 123 and FirstName = 'Bob' and LastName = 'Roberts' Finally, to make this change Is it as simple as unchecking the column and redeploying my EOModel file?
Thanks! Jeff |
