Database naming convention

Is there database, tables, columns naming convention that I should follow
when I build some information system proposed from Microsoft?
Thanks in advanced
AdnanThere have been many discussions regarding this.

I have a new book, SQL PROGRAMMING STYLE, due out the middle of this
year that deals with this topic.
I bothered to research readability, typography, industry standards,
etc. I also get into some common design flaws, heuristics, software
metrics, etc.
I am hoping that people will pick it up and use it as a guide in their
shops. Even if they don't like it, they will have a single set of
rules. And they can yell at me :)|||Thanks

Database Naming

am doing some testing on a database created by the programming dept of the
company, they named the database '123v10'.
When I run some queries (mostly admin stuff, checking the fragmentation,
space used by the data and log files, etc) in the Query Analyzer, I often
get the error message:
Line 1: Incorrect syntax near '123'.
My guess is that SQL doesn't particularly like database names that start
with numbers, am I correct? If so, will this create any real problems down
the line? I think we are at an early enough stage that the database could
be renamed if this would help.
TIA,

Yes, you are correct. However, it should not cause problems if you code
defensively (which you should be doing anyways). The problem is that the
creator of the name did not follow the rules for regular identifiers. If
you don't follow the rules, then you must take extra steps to properly
delimit the identifier name (this includes all object names - databases,
triggers, procedures, tables, etc.). Obviously, the easiest approach is to
follow the rules.|||"Scott Morris" <bogus@.bogus.com> wrote in message

To add to that. Ensure that you use square brackets [ ] whenever you
reference the db name.
Rick Sawtell|||You may get it to work by using brackets around the db name like [123xxx],
however, somewhere down the road there will perhaps be a query or
application that will choke on it. It would be best to nip it in the bud
now.

database naming

Hello Group,
where does it talk about naming databases in the books online? I thought
that a database name could not have a dash "-" in the name?
Rich
The topic is "Identifiers"
http://msdn2.microsoft.com/en-us/library/ms175874(SQL.90).aspx .See the
section "Rules for Regular Identifiers".
The only way you can includ special characters like a dash is to delimit the
name with [ ] or qoutes. See the topic "Delimited Identifiers" for more
details.
-- This fails
create database my-database
-- This works
create database [my-database]

|||Hello Gail,
here is the command I am running in the QA:
backup log intrel-dev with truncate_only
and the error I get:
Server: Msg 170, Level 15, State 1, Line 1
Line 1: Incorrect syntax near '-'.
I suspect that the database name cannot have the dash in it.
