In this presentation it will be clarified when and why parameter sniffing is a problem in SQL Server stored procedures. Of course we will offer several solutions for this problem and discuss which solution is applicable in which scenario.
In this section we will show how to avoid performance problems caused by poor query design (functions in WHERE clause, data type conversions…) and explain how local variables and parameters affect the generation of execution plan.
SQL Server optimizer doesn't use and index seek for execution of your query although the query is high selective? What is better, when and why: LIKE vs: SUBSTRING, IN vs. EXISTS, SUBQUERY vs. JOIN. Why you should not use the UPPER or LOWER functions?
In this session we will advice how to avoid common developer mistakes and show how bad designed queries reduce the SQL Server optimizer's capabilities for choosing an optimal execution plan.
Your stored procedure is slow in the application, but works perfect in SSMS! In this presentation it will be clarified why this happens and we will offer several solutions for this problem and discuss which solution is applicable in which scenario.
