SQL Server – Slow Finish

Posted on Updated on

As part of optimizing your SQL queries, if you want to line of code to include the execution plan, drag this instruction before execution.


If you want to optimize the recovery of your data in an environment with a default isolation level of Read Committed or SERIALIZBLE, slide this instruction before execution.


As part of query optimization, you can associate a clean SQL query execution plan for you so to override the behavior of the query optimizer, see reference Plan in SQL Server Management Studio, you can create your SEEK FORCE clauses on your favorite index etc.

You can sometimes just be an update statistics 🙂

For the database novice, the positioning of the index is very important and is based on real data collecting tools (Production Environment)

As for the SQL Server after try: Database Engine Tuning Advisor, included in SSMS since the 2012 version.

How to solve the fragmentation problem index?

Use Rebuild or Reorganize index

The result is obtained with function sys.dm_db_index_physical_stats.

Below results  :  

avg_fragmentation_in_percent : The percent of logical fragmentation (out-of-order pages in the index).

fragment_count : The number of fragments (physically consecutive leaf pages) in the index.

avg_fragment_size_in_pages : Average number of pages in one fragment in an index.

If avg_fragmentation_in_percent is greater than 5% and less than 30%

                => ALTER INDEX REORGANIZE

If avg_fragmentation_in_percent value is greater than 30%

Branching By Feature – Team Foundation Server

Posted on Updated on

We have several strategies branching, Foncton life cycle of the product, the number of people, delivery mode etc.
We can mention: Release Management or CodePromotion ..
the objective of this bill is to address one of the most complex, it is the featuring.


An application may include multiple versions while having active or corrective maintenance needs. How to do ?

Parallel developments can be implemented by several teams. How a team without negatively impacting the other?

=> Set up branches developments

However it is essential to establish a branch management policy to avoid manage conflicting versions during development, to prohibit changes to the validated versions etc.

Setting up

The installation requires performing the following tasks:

1. Create a development trunk, the trunk is denominated XYZ

Note: the developments are not directly on the trunk, but are on a child branch called Service Pack.

2. Create from a new branch trunk daughter Service Pack denominated 1.YZ

Note: this branch will host the developments dedicated to the first feature.

Event Project: End of the first iteration (The development team estimates that the developments are completed).

3. Create from Service Pack 1.YZ a new child branch Fix denominated 1.0.Z.

Note: This branch contains all the developments dedicated to future bug fixes following the delivery of the target functionality.

4. Create From Fix 1.0.Z. a new child branch Release, 1.0.0 wording.

Note :

-This Branch will remain read-only.

-This Branch is the only branch deployed in production environment.

-This Branch represents an image of our delivery.

It makes it possible to trace the different deliveries made.

-It Allows for Rollback operations on version if the need arises (Avoid version conflicts files).

Event Project: Delivery of production

5. Deliver the branch Release 1.0.0 on the production environment.

6. Merge Service Pack 1.YZ to XYZ trunk

Note: At this stage all branches are at the same level of evolution.

Event Project: Bugs occurs on the Release 1.0.0

7. Treatment of bugs can be done in two ways as possible:

Judging that the version is not stable
-Conduct Fixes on Fix branch 1.0.Z.

-Create A new branch Release 1.0.1

-Livrer The Release 1.0.1 branch

-Fusionner Fix 1.0.Z to Service Pack 1.Y.Z.

-Fusionner Service Pack 1.Y.Z. to X.Y.Z. trunk

Note: You can iterate many times: 1.0,1, 1.0.2, 1.0.3 etc.

Judging that the version is stable and it is decided to fix bugs on a new delivery.
-Create From Service Pack 1.Y.Z. Fix a new child branch 1.1.Z

-Apporter Fixes on Fix branch 1.1.Z

-Create From Fix 1.1.Z. a new child branch Release, 1.1.0 wording.

-Livrer 1.1.0 branch

Event Project: An important new feature arrives

8. Create from the trunk a new child branch service pack, label 2.YZ
