Best Way To Organize Multiple Databases?
Jan 21, 2008
I'm very new to SQL, so you'll have to excuse the nubishness of this question. I've got my trusty O'Reilly book here!
We're using Microsoft SQL Server 2005 on our web server. I'm currently working on a project to get a few MS Access Databases available on the web page.
The web part is actually working fine, with the DBs exported into SQL for performance reasons. (From what I've read pulling data from the .mdb file could cause me problems in the future, so I'm tossing it all onto the SQL server from the start.)
Before I get into the project full-tilt, though, I'm curious about how best to organize all the data?
I'm using the Upsizing Wizard in Access for the conversions, and every new DB gets added under Databases. If this gets approved I may be looking at well over a hundred DBs which will eventually be converted and made web accessible.
I can keep everything neat and tidy on the web server by just tossing things in a few directories, but the menu on the SQL Server Management Studio is going to become a mess really quickly if I let it just keep adding to +Databases.
Is there a way to sort everything into a series of folder/groups, like how System Databases has it?
Thanks in advance,
-Lamune

Dear Readers,Is it possible, like in Access, to link to tables in other SQL databases that are on the same server? I have a query that I originally had in Access that queered from multiply databases. It did this by having those other tables in the other databases linked to the database that had the query.

Hi,
I'm trying to create a database that takes specific information from a number of databases on different servers to make some reporting that we have much easier.
I'm pretty new to SQL so I'm not sure of the best way to proceed. I read an article that suggested I use the OPENROWSET command. The problem is, the version of SQL that came with one of the programmes we use is limited and will not allow you to turn on the allow "Ad Hoc distributed Queries" so the SLQ statement will not execute.
I'm confused why it won't let me to connect through ODBC as I've created a web page that selects data from this database with no problems!
Here is the SQL statement that I've written to make sure it is the correct one (on the msdn library page it said that this was the ODBC connection):
SELECT a.*
FROM OPENROWSET('MSDASQL','DRIVER=(SQL Server);SERVER=APPOLOACT7;UID=sa;PWD=***************',
'SELECT * FROM MDCTestAndDev.dbo.TBL_CONTACT') AS a
I've also created the ODBC connection using the tool on Administration Tools>Data Sources ODBC
Any help would be greatly appreciated (also any ways of selecting from one database and inserting it into another will be helpfull)
Thanks

Hi!
I have 7 source databases and one target database, all using the same structure. The structure is made of 10 tables, with foreign key constraints.
I need to merge the source databases into the target (which won't have any data before that process, but will already have the correct schema), and to keep the relationships between the records.
I know how to iterate over the source databases (with SMO foreach), but I'd like to know if someone can advise the best copy method for that context in SSIS ? (I don't want to keep the primary keys, but I need to keep the relationships...)
Any pointer most welcome!
best regards and thanks

I am trying to restore multiple .bak backup SQL database files onto a new server. However, I have found that it will not allow me to restore multiple databases at once. Is there a way to do this so that I do not have to manually upload one at a time? I tried adding all the .bak files at once to the backup device window but it only did the first one listed. It would be so much easier to restore them all at once so that I do not have to continue this manual process. I am restoring them via device.

Hello,
I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services?
Thanks

Hello,
This is more a informational question. Until now we had over 50 reports ready in our system, we are almost ready to go into production and are starting to link all reports with eachohter. The first problem was that we had them all nicely grouped in different projects so that we could publish in a logical folder-tree. Problem is that we can't jump to reports that are nog in the same folder. Going by url changes the layout and parts of the report manager are gone.
We then started to have a look at Sharepoint but i can't find books on the topic SharePoint & SSRS that describes the possible options. I've seen quite some documents and ways to publish reports but until now we prefer to mail the periodical reports to the users with data-driven subscriptions.
So at this moment we don't know quite wha direction to take. Putting all reports in one folder would solve many linking problems but makes it quite messy for the users.... And the linking issue is a must. As we now will start to create our dashboards with SSRS too.
So, any suggestions on what road to take or what publications to read are welcome.
Kind Regards
Harry

Hello,
I need some advice regarding organizing packages.
I am in starting phase of a data conversion project. As my ETL target, I have to produce around 70 flat files. I am creating one package for each target file. Some target files may be a result of 2-3 packages.
I have some common packages that get called from many other packages.
Before my solution tree grows into unmanageable state, I would like packages to get organized based on their target and purpose of the package.
The ideal solution to this problem would be to organize packages in a folder structure but I couldn€™t see any option to create folders in a solution.
I also noticed that we can€™t easily put package files next to each other even after renaming packages.
I was wondering is there a better or any way to organize packages in solution tree?

Greetings,I have one table, named Article, and one table name Category.The problem is, one Article could be in just one or in several categories.What is the best way to connect data between Article and Category according to fast search performance?I have several ideas:1. To have third cross table Article_Category with fields Article_ID and Category_ID, and search Article_Category table 2. To have several INTEGER columns in Article table (like Category_ID1, Category_ID2,..) and search those columns3. Add one VARCHAR field in Article table where I could write Category ID's delimited by some character (e.g. by comma), and do text search in only that column.What is recommended for solving problems like this?

Is there any way in which I could distinguish a group of Database users from the other users. Say for e.g. store the Database users hierarchically, etc. Adding a Prefix/Suffix to the user name as a distinguish-er will not work in my case. I want to restrict the deletion of these Database users. Even the login with sysadmin or serveradmin rights should not be able to DROP those Database users.

Hey there!
I'm not sure how to explain this but here goes...
I'm a bit stuck, a new project that's come about "requires" me to query multiple databases as if they were tables.
1 Oracle database which stores information on our staff (this database is a part of some MIS software and can't be changed in any way)
1 SQL Server 2005 database which stores information on staff sickness
Basically say theres 1 table in each database
Oracle DB
People
Person_Code
Forename
Surname
SQL DB
Sickness
Person_Code
Daydate
Lets say the query I want to perform is to select all the records from sickness where person code is 22334 and also get their name from the other db, so the output may look like
22334 Dann Rees 01/01/2007
22334 Dann Rees 03/01/2007
22334 Dann Rees 10/02/2007
Now I realise I can write a quick function to pull the information but this is just a basic example. Effectivley what I "need" is to be able to query sickness while sub querying people to get the names, or some kind of pass through query?
Please remember this is just a very simple example and the "actual" queries will be far more complicated, for instance finding all the employees of a certain department who is male and was sick in January. All the data for that example is stored in people (oracle) except for the dates which is stores in sick (SQL 2005). Now these are easy enough if they were tables in 1 database....but their not, their tables in 2 databases, and theres nothing I can do to change that :(
All help appreciated as this is becoming very urgent.
Many thanks
Dann

Hi all:I am trying to create a website which will search and return results that are from multiple tables in different databases. I have the code to search a singular database right now, and I tried to make a connection to a second one, which worked, but I don't know how to send the proper sql commands to the second database or how to link them in the code. Does anyone have any pointers on creating a site which will search different tables in different databases with a known connection between databases? Any help would be really really really really appreciated.-Shrey

Is there any method to automate the change so that the change is reflected in all the databases when a single database structure is changed?

Okay this is a test...actually I am still learning SQL and need some help. Does anyone have any information on being able to move indexes from one database to another. My scenario is I have 3 databases, Development, QA and Production. I want to move/copy indexes I created in Development to the QA database. I have many indexes so I do not want to have to recreated them if I can avoid it. Any suggestions?

Hi,
Currently developping a c# database based application, which will be used in different establishments worldwide. I'm currently a bit confused by the ms sql features offered. Because the huge data amount which will be fetched during application use from the database, the best option is probably to put a ms sql server in each establishment to realise quick data fething. Problem is that the servers, which are all running on the same database design have to be synchronised real-time. I read about datareplication with the merge option which I thought was a nice solution. The subscribers can only have read-only rights on these subscriber databases, because the merging doesn't work appropriate i heard, so this is no good solution. Then I read about distributing transaction coordination. Seems a good solution as well, but what happens if a server system crashes for one day and then comes back online? It won't be up to date anymore... Right now I think about a combination of these 2 features. DTC in combination with merge replication, but there must be a better solution. Fact is that a lot of users will be editing data worldwide non stop, and everyone has to be up to date. Because of huge data fetching I don't think it's a good solution to let everyone work worldwide with one single database. Is there a possibility to realise this with ms sql server? Because I'm getting more and more confused... Thx in advance.

I need some guidance! We are running SQL Server 2000. We have 4 or 5 databases with the same schema, and I need to make sure that their structures all stay synched. We will have more soon. I also need certain tables to have the same data across all the databases.
I need a way to manage changes on the multiple databases! Right now I generate a script in Enterprise Manager, then run it in Query Analyzer on each database, manually. There's too much room for error here.
Any suggestions are appreciated! I am currently evaluating Embarcadero's products, but they are complicated and confusing - I'm not sure yet which of their tools is meant for this purpose.
Thanks,
Avi

Ok, so right now we have a bunch of queries similar to the following:
Code:
use db001 select co#=(001), fieldvalue from tablename where fieldid = '1'
use db002 select co#=(002), fieldvalue from tablename where fieldid = '1'
what i need to find is if there are duplicates of fieldvalue and have it display all in one.
Basically right now we run all these there are 25 databases and we export everything to a file and then open it in excel. we then format it it so its just co# and fieldvalue and then look for duplicates.
i would like to avoid the whole excel part and just run a query that will display any duplicates of fieldvalue across all 25 databases in "tablename"
hope that makes sense. - Thanks

Could anyone possibly help me out with an issue I am having...
I need to copy all my SQL2005 databases from Server1 to Server2. How can I, using SSIS, copy all the databases and not just 1 specific one (database transfer task)???
My actual task is much deeper than this, but this is the main problem I seem to be encountering and I cannot find this anywhere on the web...
Over and above the what I have mentioned, is there a way to also specify a name of the target DB the copy will go through to?
e.g. Server 1 has 3 instances, each one with a different copy of the same DB.
I would like to copy all 3 copies to Server 2 running 1 SQL instance, but to target DB's like DB_dev, DB_prod and DB_test.
The latter section is not so crucial at the moment, but the first part is really an issues I am struggling with at the moment...
Any help would be greatly appreciated.
Thanking You in advance!!!!!

I need to design a system which represents multiple "projects" in SQLServer. Each project has the same data model, but is independent of allothers. My inclination is to use one database to store all projects.Looking at the numbers involved, however, I wonder if I would getbetter performance by storing each project in its own database.Suppose I have 50 projects, each with two users and 10,000 rows; itseems to me I'd rather have 50 x 2 users working in a table with 10,000rows than 1 x 100 users working in a table with 500,000 rows.On the other hand, the single database approach seems more elegant froma design perspective. I wouldn't be creating multiple copies of anidentical data model, and I wouldn't be creating new databases as abusiness procedure, every time a new project is required.Here are my questions:1. For the scenario described above, am I correct to assume I will getbetter performance by using multiple databases, or does SQL Server havesome clever way of achieving the same performance in a single database?2. Is the multiple database approach common? If anyone has tried it,please tell me about how it works in practice.-TC

Hello
we have SQL instance which contains databases (A, B, C...). When ever i configured LS with Standby option, and i want complete restore of database A (Primary) to stand by A (Secondary), then logs will always going to restore...
but SQL server is taking a copy of the Backup like "GJ_Temp_data, GJ_Temp_log" as the default file names, for restore the DB Backups.
if i want to set up for the database B, it is taking "GJ_Temp_data, GJ_Temp_log" again for the database B, and giving error as "the files are already in use".
If i script the Log shipping setup while enabling for Database A, and make sure that i will enabling it for remaining databases B, C, D..
Please advice, and give us best experienceS for enabling LS FOR Multiple databases on the single SQL Instance.
Thanks in advance.

Hello,
This is probably a simple solution but I'm a bit confused about which flows to use.
I have two databases on different servers that contain the same information but for the appropriate server. I want to retrieve data from each of the servers using a "select" statement.
Would I use a ForLoop and change the connection in a Script Task and then execute the SQL statement? Or can a ForEach Loop be used, but I'm not sure which type of enumerator.
Thanks for any help you can give.

Does SQL Server Everywhere supports joins across mutiple SQL/e databases on the same machine ? I have not found any examples that guide to address this issue. can anyone point me to something/help me write queries that join D1.T1 and D2.T2.
