The execution plan describes the sequence of operations, physical and logical, that SQL ServerTM will perform in order to fulfill the query and produce the desired resultset. The execution plan is produced by a database engine component called Query Optimizer during the optimization phase of query...
Well-designed filtered statistics can improve the query execution plan compared with full-table statistics. For more information about the filter predicate, see CREATE STATISTICS (Transact-SQL). For more information about when to create filtered statistics, see the When to Create Statistics section in...

If one is not found then SQL Server will create a new plan for it, which is a potentially costly operation.Some considerations for T-SQL CPU optimization are:Query plan reuse Reducing compiles and recompiles Sort operations Improper joins Missing indexes Table/index scans Function usage in ...
Specifies one or more table hints that are allowed for the target table. Table hints override the default behavior of the query optimizer for the duration of UPDATE statement. NOLOCK and READUNCOMMITTED are not allowed. For information about table hints, seeTable Hints (Transact-SQL). ...
