Fuck Django!

Disclaimer - I use Microsoft Technologies. A few jobs and hacks aside I always have. I am the first person to admit that I know NOTHING about Python, or how the Django framework operates aside from my limited experiences with it. That said...


 

Thats your database, not your Toyota stalling!

November 2, 2012
Turn the key, hear the engine catch go to put it in drive and... shit Darn it golly gee a stall. This is NOT just for cars anymore. One of the biggest performance issue indicators I have ever used in practice to check for DB issues has been an IO Stall test metric. In days of old, you know when 16 bit gaming consoles made you the man if you had one, and Mortal Kombat was THE GAME to play.. (still is now by the way if anyone is on PSN and wants to take a beating ProphetDE come find me) I had n...

Constraints, Columns, and Tables oh My...

October 10, 2012
Over the years I have been guilty so many times of writing a rollback script that rolls column additions to a table. Which is essentially a script that will drop the added columns. When i create a new column with a default value i ALWAYS use a constraint name which i created. In the event you inherit someone else database who does not (not mine of course) :) forgetting to drop the default value constraint (which is something only an inexperienced DBA would do NOT ME of course) :)

As luck woul...

Dumping IO Stats to powershell, and WTF did he just say.

October 7, 2012
Hello All,

A 2 part post this month, i guess i finally removed head from arse and got around to posting updates. First a super useful query for IO stats of log and data files. Please note these are at file level. This may exist already and im sure there are better ways to do this, but since i have been going through a ton of logs and data files at work recently, i figured it was worth a post.

[code]
SELECT
DB_NAME(tblFileStat.database_id) AS databaseName ,
tblFileStat.file_id ,tblMasterFile.phy...

Quick but useful Index Fragmentation

July 13, 2012
Since I happen to be using this right now, I figure i would throw it up. Table not performing the way you would like? Perhaps the index is fragmented to high hell. Usinf this in combination with a Reorganize and Rebuild script should help a great deal.

SELECT ps.database_id, ps.OBJECT_ID,
ps.index_id, b.name,
ps.avg_fragmentation_in_percent
FROM sys.dm_db_index_physical_stats (DB_ID(), NULL, NULL, NULL, NULL) AS ps
INNER JOIN sys.indexes AS b ON ps.OBJECT_ID = b.OBJECT_ID
AND ps.index_id = b.index...

Without further a due...

April 13, 2012
Sorry for my delay. I know i promised to move all of my old blog posts over, I had fully intended to. Finally I have come to the conclusion that I will not. The reason for this is quite simple, I have a new position and would like to post all new coding examples based on SQL 2k8 R2 and SQL 2012. With my new position as a Senior Database Engineer / DBA with incuBET Inc. I am in the privileged position to be able to do so. That being said, stay tuned to this blog for new monthly reviews, coding...
