SQL 2012 :: Multiple Databases And Schemas
Jun 9, 2015
I have a SQL Server 2012 Enterprise Edition install that I am needing to do the following:
- Provide db_owner access to a single user. Have the db_owner privilege apply for the user in all Schemas of the database (this is a generic AD account that is being used for an application).
They are wanting me to do this because they do not want to get so granular as to tell me all of the objects that the user will need specific access to in any of the given Schemas of the database(s).I have 8 databases, and each one has additional Schemas. These are all contained in a Default instance.I am finding that without explicitly applying permissions to the various objects in the Schemas that are not the default Schema for this user, I am a bit stuck.Is there any way to have the db_owner permission apply to the single user for all the Schemas in a given database (without making them a Sysadmin)?

I have several distributed databases with identical schemas that I have added to my SQL server as a set of linked servers. For the sake of simplicity consider a schema with single table with one column called Info. I would like to present a view with columns DatabaseName and Info, that presents all the rows from all the databases in a single view.
How can this be achieved this using a SQL Server View?
If not is not possible using Views, what approach you recommend?

Hey folks,
I'm looking to gather ideas on this before I start the project; so what better way to start than to ask here? ;)
The situation is this: we are in the process of replacing a large data driven application with a new one. Before turning the old'un off (that's not for a minimum of 6 months), we need to migrate data between the two entirely different schemas, and I've been tasked with writing the interfaces.
Now, here comes the kicker; they don't just want a "straight-forward data conversion", they want to run a period where they can still update both databases and any changes in the old one are to be pushed into the new db.
Because the schemas are not the same, I believe replication is out of the question so I was looking for advice as to what possibilies I have ahead of me to achieve this.
I fear I may not have expained this well enough; so as always if there are holes in the detail let me know and I'll do my best to fill them in :)
Old db = SQL Server 2000
New db = 2005
Thanks,
George

Hi,
We have two databases right now that house miscellaneous small applications. We have them in place so developers can develop small applications in them without going through the database request process and bother the DBAs. This was set up before I got here - so I wasn't involved in the decision to do such a thing. The obvious drawback to this is that a restore would wipe out data for multiple applications. As we move to a new 2005 server we are re-evaluating our methods and would like some input on this - and some other aspects.
I know that we could use filegroups and put objects related to certain applications within them so restore is independent of other apps. Each application has its own user which is granted execute on it's stored procedures.
Are we missing anything here? I'm almost tempted to try to get separate databases created to uncomplicate it. If a developer can spend hours working on an app, they can spend 10 minutes on a form and wait 30 for us to create it.
Another thing I've noticed it that it can take quite a while to grant permissions to many stored procedures to a user in 2005. In 2000 there was a grid and you could arrow down and hit space, granting execute. You could also use code to do this, be we never really needed to since developers granted as they went and we would script the object and check the 'script obect level permissions' checkbox. This has since disappeared and granting execute is another step for us.
What do you think of 'sub schemas' for each role in the application - which is usually 'User' and 'Admin'? So we would have MylittleApp_User.ProcedureName and MylittleApp_Admin.ProcedureName with execute granted on the schema for each application user. Tables would be placed in MylittleApp schema.
In the past developers simply prefix their procedure with the application name to denote what application it belongs to.
Thanks for your advice on this - we don't want to get headed down the wrong path.

I need a script that will return the mdf & ldf for multiple databases.
I am currently running...
sp_helpdb 'TestDataname'
...and copying the size of the mdf and ldf into an excel spreadsheet.
How can I get the mdf AND ldf file size for all of the databases in an instance? I need the MDF and LDF seperated and I want the actual size of the file as it appears on the file system.

Hi,
I have two databases lets say DB1 and DB2.
Schemas for both databases is same.
In both database schemas there are tables which has identity columns as primary key.
Now i want to merge these two databases in a single database say DB3.
It may also possible that some master records in both databases are common so they should not repeat in DB3
Is there any way so that i can do it quickly and as soon as possible.
Thanks in advance

We have a system with multiple modules, for each module we have a separate database. Is it better to have multiple databases or have multiple schemas. Performance, advantages, disadvantages...
When is too much too much, 10-25-50-100 Schemas???
Course.dbo.table1
Program.dbo.table1
vs.
NEWDB.Course.table1
NEWDB.Program.table1
Thanks

I have an xml task that I have set up to validate my xml using a XSD. It seems to be working OK. However, I have had to wrap my xml in a SOAP envelope before I send it to the validation task so I need to include an additional schema for the soap message header. That "header" schema has an <xsd:import> of the soap envelope schema. When I try to <xsd:include> the message header schema I get this:
"Warning 313 The targetNamespace 'blah blah' of included/redefined schema should be the same as the targetNamespace ' blah blah blah' of the including schema."
Is it not possible to use the Xml Task to validate the entire document including the SOAP Envelope due to the differing target namespaces? Thanks for any suggestions.
(I have SP2 installed.)

Hi,
I have the following scenario: N identical Databases (corresponding to different Fiscal Years, with names <Company Name>.<YEAR>). We want to consolidate the N DBs to a New Datawarehouse.
In SSIS we have designed a Dataflow that reads through a OLE DB Source (Connected to one of the N Databases) and maps to a OLE DB Destination (Connected to the NEW DB).
The question is, how we loop in SSIS through the N identical Connections, so to repeatedly execute the designed Dataflow, each time with a different Connection?
Thanks in Advance,

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

I concatenate multiple rows from one table in multiple columns like this:
--Create Table
CREATE TABLE [Person].[Person_1](
[BusinessEntityID] [int] NOT NULL,
[PersonType] [nchar](2) NOT NULL,
[FirstName] [varchar](100) NOT NULL,
CONSTRAINT [PK_Person_BusinessEntityID_1] PRIMARY KEY CLUSTERED
[Code] ....
This works very well, but I want to concatenate more rows with different [PersonType]-Values in different columns and I don't like the overhead, of using the same table in every subquery ([Person_1]). Is there a more elegant way to do this, without using a temp table or something else?

Hi All
I have a question about having one or multiple databases for a large project. What are the main differences between designing my database as one or breaking in to multiple databases. I should mention that there are many relationships between tables in different DBs in the multiple DBs state?

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

We have a number of databases(on sqlserver 7.0) which has the same structure but with data for different users. We would like to change the structure of the databases with minimum effort and with minimum down time.
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?
Any suggestions in this regard are welcome and urgent

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?
Thanks!

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!!!!!
