Execution Plan Generation,cause the overall time required to execute a query is the sum of the time required to generate the execution plan plus the time required to execute the query based on this execution plan, it is important that the cost of generating the execution plan itself is low or that a plan gets reused from cac

Parameter Sniffing,the many ways to improve the overall performance of the system. One of the best mechanisms for ensuring plan reuse is to parameterize the query, through either stored procedures, prepared statements, or .. All these mechanisms create a parameter that is used instead of a hard-coded value when creati

Query Recompilation,to parameters. This allows execution plans to be reused when the queries are resubmitted with the same or different values for the variable parts. Since stored procedures are mostly used to implement complex business rules, a typical stored procedure contains a complex set of SQL statements, making

Query Design Analysis,res guarantees good performance if your queries are written badly in the first place. The SQL queries may not be able to use the available indexes effectively. The structure of the SQL queries may add avoidable overhead to the query cost. Queries may be attempting to deal with data in a row-by-row f

Query Store, Second, the Query Store creates a mechanism for directly controlling execution plan behavior in a way we’ve never had before. Finally, the Query Store acts as a safety and reporting mechanism for database upgrades that will enable you to protect your systems in new ways.
