3. 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:

4. 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

5. 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.
to store intermediate results and “short circuit” execution.

6. …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.

7. 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

8. Tracking Statistics IO
How does this technique help? It helps interpret this…….

Power Query…

12. 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)
= Source{[Salary]}
* 1.05

Tips and Tricks
Leverage the UI
Generate steps using the UI, then tweak the code.
Formatting is easier in the UI.
Some things only work through the UI (“auto steps”).
