SQL SERVER – Weekly Series – Memory Lane – #028

Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane.

2007

UDF – Function to Convert List to Table
Article contains UDF written for SQL SERVER 2005. It will also work well with the very big TEXT field. If you want to use this on SQL SERVER 2000 replace VARCHAR(MAX) with VARCHAR(8000) or any other varchar limit. It will work with INT as well as VARCHAR. It will convert the list to table.

Creating Comma Separate Values List from Table – UDF – SP
Script contained in the blog will create common separate values (CSV) or common separate list from tables, convert list to table. Following script is written for SQL SERVER 2005. It will also work well with the very big TEXT field. If you want to use this on SQL SERVER 2000 replace VARCHAR (MAX) with VARCHAR(8000) or any other varchar limit. It will work with INT as well as VARCHAR.

Examples and Explanation for GOTO
GOTO statement can be used anywhere within a procedure, batch, or function. GOTO can be nested as well. GOTO can be executed by any valid user on SQL SERVER. GOTO can co-exists with other control of flow statements (IFELSE, WHILE). GOTO can only go(jump) to label in the same batch, it can not go to label outside of the batch.

Index Optimization CheckList
Index optimization is always interesting subject to me. Every time I receive request to help optimize query or query on any specific table. I always ask Jr.DBA to go over following list first before I take a look at it. Most of the time the Query Speed is optimized just following basic rules mentioned below. Once following checklist applied interesting optimization part begins which only experiment and experience can resolve.

Explanation SQL Command GO
GO is not a Transact-SQL statement; it is often used in T-SQL code. Go causes all statements from the beginning of the script or the last GO statement (whichever is closer) to be compiled into one execution plan and sent to the server independent of any other batches. SQL Server utilities interpret GO as a signal that they should send the current batch of Transact-SQL statements to an instance of SQL Server. The current batch of statements is composed of all statements entered since the last GO, or since the start of the ad hoc session or script if this is the first GO.

2008

Here are two straight to script blog posts where I explain how to do something quickly and easily.

2009

Find Last Date Time Updated for Any Table
If a user wants to finds out when was the last table updated he can query dynamic management view (dmv) – sys. dm_db_index_usage_stats and easily figure out when the table was updated last. Let us comprehend this example by creating a table and updating it. We can use dmv to determine when it was updated last.

Questions and Answers with Database Administrators
Interesting conversation – I recommend everyone to read this.

Q. According to you what goes into making the best Database Administrator?

A. The primary job of DBAs is to secure the data. They should be able to keep it safe as well as reproduce it efficiently, whenever required. So as per my view, a Database Administrator who can fulfill the requirements of Securing Data and Retrieving Data is the best DBA.

When I hire a DBA I always ask them questions about backup strategies and efficient restoring methodologies.

Do we know what kind of lock WITH(NOLOCK) hint takes on object. Answer is Schema Lock. Yes, WITH(NOLOCK) hint takes Schema Lock on the object which is accessed. In this blog post we have working example where I demonstrate the same.

Resource Database ID – 32767
The Resource database is a read-only database that contains all the system objects that are included with SQL Server. SQL Server system objects, such as sys.objects, are physically persisted in the Resource database, but they logically appear in the sys schema of every database.
