Some links for scripting SQL Server Backups and setting up maintenance plans

Posted by jpluimers on 2013/10/30

I need to do some research to automate the backups and restore sequences of some SQL Servers.

Here are some links and notes to get started:

SQL Server: “there’s nothing so permanent as temporary”

Posted by jpluimers on 2013/10/24

“there’s nothing so permanent as temporary” can apply to many things, for instance Kitchen and software development (there technical debt is very applicable), the financial top gap measures (which are real debt) of fanfiction. You can apply it to SQL Server as well. The TempDBhas been there since before SQL Server 7, which means it has established a permanent feature for quite some time now.

Your DBA (which might be you) needs to watch the temdb size or space on the separate volume where temdb is stored, or someday the TemDB access patterns will cause havoc.

The most used feature (there are more) in TempDB is temporary tables (often abbreviated to “temp tables”), which – since TemDB got there – has come in three flavours:

The table variables are created and released implicitly. The temporary tables (one of the Special Table Types) can be created either explicitly using a CREATE TABLE, or implicitly using SELECT … INTO. You’d think that temporary tables are indeed temporary. But they are not:

Temporary tables are semi-temporary. Not actually permanent,  but not fully temporary either.

All flavours of temporary tables are not being fully deleted when they go out of scope. When they go out ot scope, they will get an implicit/automatic truncate to empty them (so there is no manual TRUNCATE TABLE or DROP TABLE needed). But the table itself lives on including any cached plan information. They can, and often will be reused. And that’s where you should start reading these links:

One more thing: as of SQL Server 2012, the OBJECT_ID associated with temporary tables is negative.

SQL query to get the deadlocks in SQL SERVER 2005 and up

Posted by jpluimers on 2013/09/05

Darren Davies answered via SQL query to get the deadlocks in SQL SERVER 2008 – Stack Overflow a while ago listing a great SQL statement by Mladen Prajdić that shows how to do without the deprecated SP_LOCKS and SP_WHO2 (which is undocumented, and slightly different from SP_WHO) or the good old SP_LOCK2.

It is the textual equivalent of the Deadlock Graph, which is part of the SQL Server Profiler.
I like that profiler a lot (read this step-by-step intro if you haven’t used it), but some environments consider it too much power for a developer to use.

The SP_LOCKS documentation directs you to the sys.dm_tran_locks documentation, which is the base of the SQL below. It requires the mostly harmless VIEW SERVER STATE permission.

Finding out what to join in order to get some readable results suited for quick troubleshooting is quite an undertaking.
Mladen did all that, and this is his SQL: Read the rest of this entry »
