SQL SERVER – 2012 RC0: Fix Setup Error: File format is not valid

I recently had long email conversation with one of the blog reader who was struggling with installing SQL Server 2012 RC0 installation. I just thought I will publish what we have done and how we solved problem so if you are facing the same issue, you can avoid the same.

Though our conversation was very long – I have kept only relevant conversation here.

User: While installing the SQL Server 2012 RC0 the error which is displayed is: File format is not valid.
Pinal: Download the iso format idea again.
User: Downloaded the iso media and extracted it again into C Drive and attempted the installation – still the same error.
Pinal: What is the tool you are using to extract the file?
User: (Some tool)
Pinal: Use alternate iso extractor tool or  winrar to extract file.
User: It worked!

The original media was all fine. However, when user was using a software which extract the files from ISO to folder, it was corrupting few files. Well, if you face this issue remember to attempt new software to extract your file. If that does not work, try one more time to download the file.

SQL SERVER – Bad Practice of Using Keywords as an Object Name – Avoid Using Keywords as an Object

Madhivanan is SQL Server MVP and very talented SQL expert. Here is one of the nugget he shared on Just Learned.

He shared a tip where there were two interesting point to learn.

  1. Do not use keywords as an object name
  2. [read DHall's excellent comment below]

He has given excellent example how GO can be executed as stored procedure. Here is the extension of the tip. Create a small table and now just hit EXEC GO; and you will notice that there is row in the table.

Create Stored Procedure
CREATE PROCEDURE GO
AS
SELECT
1 AS NUMBER

Create Table
CREATE TABLE T1 (ID INT)

Now execute following code
INSERT INTO T1(ID)
EXEC GO;

Now when selecting from table it will give us following result:
SELECT *
FROM T1

Now see following resultset:

So without inserting any data we inserted the data, well indeed good puzzle but very bad practical practice. Every body should be aware of this gotcha and avoid it. Thanks Madhivanan for teaching this interesting learning.

SQL SERVER – Error: Deleting Offline Database and Creating the Same Name

Offline database is very interesting subject, and there are a couple of interesting details associated with it, which one must know.

There are two common queries related to offline database:

1)      My hard drive is getting full and I deleted my ‘offline’ databases. After deleting my offline databases, my hard drive is still full and there is no empty space.

2)      I recently deleted the ‘offline’ database, and now, when I am attempting to create database with the same name, it is giving me error that the database file already exists.

I can see why these questions are coming up frequently. The common understanding that seems to prevail is that when any database is deleted, files associated with the database (.mdf, .ndf and .ldf) are deleted automatically. This is true for any database that is an ‘online’ database. However, the behavior is bit different in the case of the ‘offline’ database. When any ‘offline’ database is deleted, files associated with the database are not deleted automatically. All the files related to the ‘offline’ database need to be deleted manually after deleting the offline database.

SQLAuthority News – Microsoft SQL Server ODBC Driver for Linux Available Now

Yesterday I went to watch movie based on recommendation of the readers on my Facebook page. If you think we only discuss SQL on facebook page, it is not correct. We discussion pretty much everything what DBA do in their daily life.

During the movie, someone recognized me from our blog photo. He changed his sit and while I was watching movie and asked couple of quick question. I understand it is a bad manner to talk in movie while others are watching but still answered him quickly. Let us call him Jatin.

Here is our conversation:

Jatin: Are you Pinal Dave?
Pinal: I guess so.
Jatin: Guess?
Pinal: I am.
Jatin: I have one SQL question?
Pinal: Sure – can we talk after the movie is over.
Jatin: This movie is boring any way.
Pinal: Hm… Some may like it too. Any way we should talk afterwords.
Jatin: Answer me when you can – how can I connect from Linux box to SQL Box?
Pinal: Oh… why do you want to do that?
Jatin: Now you are asking me question and prolonging the conversation – see you lost interest from this boring movie.
Pinal: Oh…I did… (silence)… you are correct. Let us talk after the movie.
Jatin: Nice blog by the way, I read it every day.

Well, that was it, after the movie was over – we all rushed outside and never connected. I never met Jatin afterwords, Infact, I do not know what is his real name. I wanted to answer his question and reason why he wanted to use Linux box to connect to SQL Server installed machine. Any way, Jatin if you are reading my blog everyday as you said, here is your answer. Please leave your answer in comment as well – do mention your real name and details so we can continue our conversation.
