Best Practice For Data Dictionary In SQL Server 2005
Sep 1, 2006
Hi ,all here,
Would please anyone here give me any guidance and advices for best practice of data dictionary in SQL Server 2005?
I have restored a large insurance claims database with up to more than 300 tables, massively, most of them are empty tables, many of them dont have any keys, contrains, indexes, and more difficult, there is no any data dictionary for the database which gets me stuck in the understanding of the data at the moment. Thus I think data dictionary is very important for a database.
Will anyone gives me advices for that? Really need help.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

Is there any tool for data dictionary? Basically there are no
descriptions/comments to many of the columns (about 99%) in the database. Datawarehouse team does not know exactly what those columns are, where its used, how its used. No comments have been defined in the system tables. We would like to have a tool where SME's/Bussiness analysts enter the description for the columns in the production database. We have SQL Server databases, many oracle dbs, few sybase databases, ACCESS. Sometimes we might have to search for strings in the descriptions entered.

(I tried to search for answers before posting, but had difficulty)
I have read in Microsoft forums that you "can" install SQL 2005 as an instance on a SQL 2000 server (not clustered.)
My decade+ of experience tells me it would be a bad idea, I'd expect the next service pack to fail or some other un-expected result. This is for a high availability application where the vendor requires SQL2000, and our custom coders want to use some SQL2005 featuers.
Does anyone have experience with two instances of different versions in a high visibility production system?
Does anyone have some points I could use to argue against this other than me sounding paranoid.
Thanks!

I need to build a data dictionary for a SQL 7 DB that already exists that has over 16000 columns. What I really need is to add a comment to the table and column names.We use ERWin and have looked at the Microsoft Repository
but I would like a quick interface to create the descriptions which neither one of these have. I scripted out all the table and column objects into tables and built a simple Access Form to handle the updates. Now I need to
commite these updates to the Microsoft Repository. Has anyone seen or tried something like this?
THanks

I am adding tables to a DB. I want to put table and column descriptions in as I go.
1. Is there a "Description" property for the table? I see in the column properties list a "description".
2. Once I have my descriptions all in, indexes set etc, is there a system stored procedure that I can run that will generate the data dictionay? (With a table description.)
Thanks

In SQL 2k5 every db object say table , table fields etc have extension properties . I plan to populate these extension properties with meta data related information like field description , string length , case conversion , field alignment , enum options etc .
I wish to know if anybody has done, anything like this . Can this properties be easily avaialble in .Net development , reporting services , BIDS etc . Can there be significant advantages wrt this .
I would like to get user experiences .

Hi,
I'm thinking of implementing a rudimentary Data Dictionary for a database using extended properties to store table and column descriptions.
Does having this information for every table and column in a database (200 tables; 2000 columns) cause any (negative) impact on database performance? I'm guessing it shouldn't but want to make sure before implementing this in the production environment.
Thanks,
Smitha

Hi, i'm wondering which is the best way to search data in a SQL Server.
I reach data using Data Sources and Data Views and also with OLE DB Source with a Data access mode: Named query.
I have to write the data into a Flat File. So, does any one knows which is the best practice for this? Or any one of the two are good choices?
Thanks for your help.

I'm just wondering if it is bad programming practice to have many data sources on one page. I need a "Matrix" type of page that grabs data from many tables and so far I have 5 data sources. Is this common or is there something I should be doing to make it more efficient?

Hi,
I have a database on sqlserver 2000 which contains some tables which receive Create/Read/Update statements from applications, and +-5 tables which contain a sort of read-only data: the applications are only reading from these tables.
Sometimes these 5 tables need to be updated with new data. Currently I am doing this as follows:
Execute a long-running operation (e.g. 1 week), which will add new data, against a Test-database (which is a restore from a backup of the original database)
Some people do some checks to see if the new data in the Test-database is correct
If (2) is OK, the only thing which needs to be done is copying the data of the 5 tables in testdatabase to the 5 tables of the production-database.For (3), I currently use a DTS-package which consists of a "Copy SQL Server Objects"-task. This task is configured to copy the 5 tables (objects) from testdatabase to productiondatabase. The data in these 5 tables is around 20GB, and this task takes a lot of time compared to a backup/restore of the same size of data. I already tried to speed it up by creating different filegroups and wanted to restore only 1 filegroup but you can read here that making a filegroup backup on a testdatabase and trying to restore it on a production database won't work. Is there some other way to speed this up? Is my current way of working good practice?
Thx!

We are working on converting to SQL 2005 database. During the conversion we are having to rewrite a lot of code and doing a lot of intital testing and development on development data. This is causing our transaction logs to really big. I have created a maint plan that runs nightly that does a back up of database and tran log but throughtout the day the tran logs are getting really big and eating up a ton of disk space. Does anyone have suggestions on what sort of maint plan I can setup to run on my developement data where as at this point I am not concened about being able to roll back the database just keep is small as possible and "healthly"
All ideas are appreciated
Thanks

Hallo I need some hints because I would like to set up my service broker in the proper way.
First: I'm going to setup service Broker between 2 databases on the same sql server instance.
My Goal: I insert the data on table1 in the DB1.On table1 there is a trigger that begin conversation and send the message to the service on the DB2.
On the receiving queue there is an Activation that take the xml message, shred it and save the content on th table 2 on the DB2.
Actually this SP is my main concern because the shred and insert involves also several checks so it could take "a while".
Volume of data: it seems that there are 100-200 daily insert in the table1 on the DB1 and it is possible that some of them arrives at the "same time".
Very quickly:
On the DB1 the trigger:
Notice that I reuse always the same conversation and the send queue as RETENTION = OFF
begin transaction;
begin
set @dialog_handle = (select conversation_handle from sys.conversation_endpoints where far_service='ReceiveService');
if @dialog_handle is null
BEGIN
BEGIN DIALOG CONVERSATION @dialog_handle
FROM SERVICE [SendService]
TO SERVICE 'ReceiveService'
ON CONTRACT [MainContract]
WITH ENCRYPTION = OFF;
END
SEND ON CONVERSATION @dialog_handle
MESSAGE TYPE Message ('uyiuy')
commit;
END
On the DB2
ReceiveQueue is defined as:
CREATE QUEUE [dbo].[ReceiveQueue] WITH STATUS = ON , RETENTION = OFF , ACTIVATION ( STATUS = ON , PROCEDURE_NAME = [dbo].[OnReceivedTrade] , MAX_QUEUE_READERS = 100 , EXECUTE AS N'dbo' ) ON [PRIMARY]
But most important is the Activation's SP and this is the main code:
while (1 = 1)
begin
begin transaction
-- Receive the next available message from the queue
WAITFOR (
RECEIVE top(1)
@message_type=message_type_id,
@message_body=message_body,
@dialog = conversation_handle
FROM ReceivedQueue
)
if (@@ROWCOUNT = 0)
BEGIN
Rollback Transaction
BREAK
END
SET @ErrorSave = @@ERROR ;
IF (@ErrorSave <> 0)
BEGIN
ROLLBACK TRANSACTION ;
SET @ErrorDesc = N'An error has occurred.' ;
END CONVERSATION @dialog
WITH ERROR = @ErrorSave DESCRIPTION = @ErrorDesc ;
INSERT INTO [dbo].[tblLog] VALUES(@ErrorDesc,NULL)
END
ELSE
BEGIN
'this is the SP that does most of the work
exec [dbo].[sp_ShredXMLMessageToRelationalData] @message_body
END
commit transaction
I have to say that everything works fine but I don't think that it is completly performant.
I read several blogs/forums and now I'm confused on the best way to implement service broker messaging:
These are my questions:
1) I read that is the DB's are in the same instance It can improve performances the send the message directly on the Queue2.
Can be useful in my case? How to implement it?
2)In my case it is necessarly that I send a message back to the initiator?
3) In my case the conversation never end. I don't think that this is correct but in case of the data push who has to END the conversation? The target? the initiator? never end to avoid overhead (I read that big overhead is caused by the BEGIN and END DIALOG)?
3) where (initiator or Target) and how to handle the service broker error? In my case my applications are SPs and I need to inform the developer or DBA that something went wrong during the processing ( conversation or shredding stored procedure).
4) In my case is should be a good idea to think about how to solve the possibility of the "poison messages"
for sure I will find out other questions...
Any hint, link is appreciated!
Thank you very much!

Hi All,
I am using SQL Server 2000 Enterprise Edition fully patched. Database is in Simple Recovery mode.
I need to change a column's data type from "int(4)" to "smallint(2)". I know for sure that there will be no data (precision) lost, because I know the possible values that this column could have.
My problem is that the table I am dealing with has 600,000,000 records in it. I dropped all indexes before I tried to alter the table. But still it is taking forever and filling up my 280GB disk with transaction log file.
I know that in Oracle, if I want I can turn off logging and do these kind of modifications relatively faster.
I was wondering if there is a way of disabling logging before running this alter command.
What is the best practice to handle a situation of this sort?
I appreciate your help.
Thanks in advance,
Sinan Topuz

Here is my idea but I am looking for the best practice.
Each record can have 3 possibilites.
I would read and write the data 3 times to different tables and add an identity key on all 3 files then I would reassembe the data back together on the identity key and map the data to a fourth and final table.
Any other ideas?
Thanks,
Larry

I'm developing a report which contains a number of matrixes which are ordered in a hierarchy which can be navigated using a document map. One of the matrixes contains a subreport containing a table which displays a description for the matrix and the corresponding document map label. This is working without problem already in the production environment.
Recently, after updating my machine with numerous updates and patches, this stopped functioning. I now receive the error message, "The given key was not present in the dictionary" when I run this subreport, either as part of the greater report or on its own.
I have seen the posting which recommends deleting the report.rdl.data files. This did not solve the issue.
The data and the dataset are both in sync. When I click the "Print layout" button when previewing the report in Visual Studio .Net 2005, I can view the data. This looks like a bug in the VS.NET 2005 report designer.
I am running SQL Server 2005 SP2.
Any help is appreciated.
Regards,
Bill Mueller

I need to sort my data more than just order it using Order by clause.
I need the, to appear so that they are sorted like in dictionary's order.
example: if I have 0.1 and 0.2 and 0.11
They need to be ordered into 0.1 then 0.11. then 2.0. etc.
I thought I could use Val() function but it wasn't a successful attempt. Anyone can help me please?
I'm using ColdFusion and this is one of the query :
<cfparam name="sort" default="goal_cd">
<cfquery name="GetTheme" datasource="#application.OUSDSN#">
Select goal.*,theme.*
From goal,Theme
Where goal_theme_id = theme_id
Order by #sort#
<cfif sort is "goal_cd">
Order by Val(#sort#) <--------------------- This doesn't work!!!
<cfelse>
Order by #sort#
</cfif>
</cfquery>

What is the usual way to develop ASP.NET websites locally using a database and then migrate everything to the real webserver?
Here's what I'm doing now -- tell me what I should be doing instead (I'm a newbie developer).
