To Timfle and VK:

Tim, I for one take great offense as to your "SARCASM", it is truely non-professional, from an individual who claims to have so much time being professional.

Both: the bickering back and forth is doing nothing more than taking bandwidth and showing a narrow-mindness from at least one of you.

As for the links:

msdn - http://msdn.microsoft.com/en-us/library/ms186388.aspx (SS2008, but is applicable to ALL previous versions)

BOL - 2005 ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/udb9/html/4e4f739b-fd27-4dce-8be6-3d808040d8d7.htm

Also - http://www.sql-server-performance.com/articles/dba/System_Databases_in_SQL_Server_p1.aspx

These are just a few.

The model database has worked this way since the creation of the Sybase SQL Server database system, from which MS SQL Server came from.

So can we NOT try to start WWIII and the recreation of the USSR?

SQL Server 2005 has following default settings of model DB.

MDF = 3mb

LDF = 1mb

So infact question is not appropriate.

Just to share my results, i've just tried it on my test environement:

I'm sure my Model Database was not changed.

I Agree

this is not a good question because you can set sql so that a new database is initiated with 1gb of size.

This is the 3d question today which the question or possible answers are not correct, and i don't mean to I answered them wrong.

TomThomson SSC Guru Points: 104773 More actions · Answer 6

I agree with many of the comments so far: this was not a good QOTD.

The correct answer is that the a default create with no parameters supplied other than the name will create a db with primary data file size same as in the model db and log file size 1MB -or maybe not 1MB but something else? I think Hugo gave some strange rules for initial log file sizes which are not the same as those given in the BOL entries for Create Database in T-SQL Reference for SQL2008, for SQL2005, or for SQL2000, and he referenced MSDN documentation for them.

The options for the answer all all just numbers of MB, so the question needs to specify the version of SQL Server (and maybe whether it is an evaluation copy or some beta or the ready to go version), and even then the person trying to answer would have to assume that it was an implied rule that the model database size was as shipped by MS - and even with that assumption the edition of SQL Server as well as the version would have to be stipulated, because the size of the model database files varies from edition to edition: that the sizes of the model database files are not the same in all editions is documented in BOL: for SQLS 2005 in http://msdn.microsoft.com/en-us/library/ms186388(SQL.90).aspx, for SQL 2008 in http://msdn.microsoft.com/en-us/library/ms186388.aspx, and for SQL 2000 in http://msdn.microsoft.com/en-us/library/aa174522(SQL.80).aspx.

Heh... the correct answers are actually missing for all versions.... "Based on Model" and "Too Small". 😛

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Best response yet, IMHO.... 😉

Douglas Elwood SSC Eights! Points: 997 More actions · Answer 10

It appears there is confusion rampant with this question.

It asks how large is the database. The question does *NOT* say anything about what are the total sizes of the files created.

Since the .mdf file is essentially the "database" and the .ldf file is the transaction log, this question is poorly worded, badly formed and subject to existing sizes in the model database - which is well beyond the scope (or probably the intention) of the question.

The version issues (SQL 2000/2005/2008) notwithstanding, this is just someone trying to be cute, not ask a meaningful question.

I love the questions that make me think or teach me something - neither of these attributes were present in this question.

Sorry to be harsh, but questions like this should not be posted.

Not sure where all of these 3mb/1mb numbers are coming from but when I do fresh installs of SQL 2005 or 2008 (which I do a couple of times a month in the classroom from a dvd) the new databases always default to 2mb for mdf and 1mb for ldf and that is for dev, standard or ent editions. I also checked my production servers on 2005 and 2008 and I could not find one that defaulted to anything else... great question and sort of has me thinking, but that creates 2 more questions:

1. Who is going to use a 2MB database?

2. Didn't someone say "size doesn't matter"? 😉

Fascinating isn't the word I would use for this discussion: the number of different wrong answers suggested is amazing, very few people seem to have noticed that there is no correct answer available. Perhaps "Astounding" would be a better word ths time (I hesitate to suggest "Appalling" because there were a few good comments).

Surprising is my word. Just shows how little you need to understand the product to use and administer it. No wonder Microsoft rules the software world and I can be a DBA...
