Ms sql view not updating
Presume that the Tickets table has a Ticket Template Id field that indicates what template is to be applied to the ticket.
Once this value has been assigned, the following UPDATE statement could be executed to copy the template's pre-defined values to the non-assigned data points in the Tickets table: UPDATE Tickets SET Priority Id = ISNULL(Tickets.
Ever so often, queries include some aggregates data.
It returns TRUE if a non-NULL value is found, otherwise it returns FALSE.
Creating a view and indexing that view is often an overlooked solution.
However, an indexed view might perform much better with less performance hit (on INSERT, UPDATE & DELETE) compared with an index.
