Ernest Ostrander About me… Currently living in Bogota, Colombia Using SQL Server since SQL Server 7.0 Certified in SQL Server 2012/2014. Let’s connect: https://www.linkedin.com/in/ernest-ostrander-1913b912/

Sample Tuning Technique: Query Folding What is Query Folding? Combining This: UPDATE dbo.Customers SET CustomerName = rtrim(ltrim(CustomerName)) SET CustomerCity = rtrim(ltrim(CustomerCity)) Into This: UPDATE dbo.Customers SET CustomerName = rtrim(ltrim(CustomerName)) ,CustomerCity = rtrim(ltrim(CustomerCity)) 2 Table Scans 1 Table Scan

Sample Tuning Technique: Refactoring Refactoring code can mean many things… Use a #temp table to replace commonly used inputs. Use EXISTS() clause to replace more expensive subqueries or outer joins. Use @Variables to store intermediate results and “short circuit” execution.

…Tuning Technique: Tracking STATISTICS IO Characteristics of These Tuning Opportunities? No one query shows up on a hit parade of evil queries. Looking at execution plans won’t help. Adding indexes likely just disguises the core issue. Manual detection is key. This technique is for monitoring progress toward a solution, not detecting opportunities.

Tracking STATISTICS IO? Measurement Technique: Statistics IO Limitations of Statistics IO Does not report statistics for operations inside function calls. Pre-SQL2012 SP2, reports incorrect results unless explicitly declaring MAXDOP = 1

Tracking Statistics IO How does this technique help? It helps interpret this……. Table 'StoredProcAudit'.

Tracking STATISTICS IO Power Query…

Power Query: Language Flow Evaluation is like a stored procedure with no body. This Power Query expression (ignore syntax specifics): let Source = Sql.Database("localhost", "AdventureWorksDW2012"), DimEmployee = Source{[Schema="dbo",Item=“DimEmployee"]}[Data], DimRaise = DimEmployee{Salary}*1.05, in DimRaise Translates (ignore syntax specifics) into this: CREATE PROCEDURE PowerQuery @Source = nvarchar(File) ,@Employees = Source{[Salary]} ,@Process = @Employees.Salary * 1.05 RETURNS @Process
