I have a problem in that a database I have created required splitting into three databases. The records were similar but reporting and maintenance differed enough that splitting the data seemed the best option. So now I have three databases that are needing to be updated from one file and I am not sure how to do that. See the illustration below. The Machine table is a one to many to the Job table, the Job table is a one to one with the Run Data.
The first idea was to query the first database if the record was not found go to the next. If no match was found in any table drop it in a reject bucket. Then what about perhaps a lookup table with starting and ending Job ranges. I would query it to find the correct database then do another query to update the record. But then I could have some type of joining table. Not sure how that would look across databases.
The tables I am updating or adding new records to has the same fields, unique key across all the databases. I could make one big table which gets rid of the query to find the correct database to update but I still would have to connect this back to the Job table which brings me back to a join table or index table.
hi, i have one database ASPNETDB.MDF created by default when adding a user to my site, and MyData.mds - my database...i want to join the aspnet_Users table with another table created by me (in myData.mds), how can i do that? is hard if i should re-write all the data from myData into the ASPNETDB,i even writed both connectionStrings in the web.config but still with no succes... is there any trick in the SQL statment? please help me thank you
Hi, I want to get the results of a query between 2 tables that exist in the same server but in 2 different databases. I want this query to be executed in a stored procedure (use the reults in a cursor), or if it's possible to be used in an ado dataset or a simple dataset in Delphi. Can this be done also if the two datases (MSSQL) exist in different servers?? Can anyone show an example of how to accomplish these tasks??
I have a basic sql statement, where I have a usersID, and I want to joing that usersID to another table in another database to get the users first and last names. How do I join across databases... each with a different connection string? Here's what I want.. Select usersID from tableA in databaseA, and usersFirstName, usersLastName from table B in database B where the usersID from tableA = the usersID in tableb.
This is the scenario. Is it possible to create views or something (like Oracle DB Links) in a database in Instance 1 which can show data from another database in 2nd Instance ?
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
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.
When uninstalling an instance, is there a parameter on the uninstall (setup.exe /qb REMOVE=ALL INSTANCENAME=XXXXXXXX), to remove all the databases associated with that instance?
Microsoft listed 32,767 as the max # of databases for a SQL 2000 instance but I am curious what is the comfortable # of databases we should have before running into issues such as performance degrading etc.
Scenario: a stored procedure is executed in database ABC. The procedure includes a MERGE statement with objects in the ABC and DEF databases. A Windows login is executing the procedure. Contained users is not enabled anywhere on the instance. And the user is not orphaned in either database, i.e. the login is associated to the user correctly by-sid in each one.
Of course, the Windows login must be authenticated to access database ABC, and authorized to execute the procedure. That is happening. Most of the time, so is the MERGE statement. But every once in a while we're seeing an odd "Network error code 0x2746 occurred while establishing a connection" message. The procedure has a TRY/CATCH retry loop around the MERGE statement, so it enters that loop. Re-read: the procedure is still running, the network error wasn't about the client connection executing the procedure. So what was it about?
Does that MERGE statement, accessing database DEF, require SQL to authenticate the Windows login again, because it's a different database (even though it's on the same instance, and was already authenticated for ABC)? There shouldn't be any other network activity involved in that phase of the execution. Plus, when the process had been using a SQL Server-authenticated login, this never happened.
But before I go blaming our DCs or network... I need to know, are they in fact involved here, or not? I believe they are, but... never had to care enough before to really know. I'm trying to stave off the "let's switch it back to a SQL login" demand that's sure to come soon, if I can't find an appropriate resolution to this.
Is there a way of limiting the "Databases list" to just the databases which I have permission to? My databases is in a hosted environment, and the list of databases on that server is HUGE.
Can someone explain what does this mean? This is from http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx
<quote>However, all these techniques for coordinating client redirection with a database mirroring have an important limitation. Database mirroring occurs only at the database level, not the server level. Be careful if your application relies on querying several databases on a server, or uses multi-part object names to query across several databases. When several databases reside on one server, and they are mirrored to a standby server, it is possible that one of several databases might fail over to the standby but the others remain on the original server. In that case, you might need one connection per database that you are querying, so that you do not attempt cross-database queries on a standby server where only one database is a principal and the remaining are mirrors.</quote>
Also I read somewhere that if one mirrored DB fails, all other mirrored DB should also be transferred to the mirror.
For example: Let's say Srv1 (principle) and Srv2 (mirror) and Srv3(witness) are SQL servers with only default instances. The SQL instance has 4 DBs (DB1, DB2, DB3, DB4) and all of them are mirrored to Srv2.
An ASP.NET application has four seperate connection strings like: objConn1 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB1;Integrated Security=True; objConn1.connect();
objConn2 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB2;Integrated Security=True; objConn2.connect();
objConn3 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB3;Integrated Security=True; objConn3.connect();
objConn4 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB4;Integrated Security=True; objConn4.connect();
If DB2 failsover to Srv2 (mirror), why should all other DBs be failedover?
I have to mirror 3 DBs on my sql server instance . I have restored there full backups and log backups on mirror.I have also created endpoints on principal and mirror using default ports 5022 and 5023.
know if i can use the same endpoint for the databases on principal instance ?
Why are the user databases that were created in the MSSQLSERVER default instance showing up in the newly created ALPHAONE instance? I'm successfully logging into the alphaone database as it shows as "DASAlphaOne,1xxxPport) at the top of the treeview in ssms. I'm logging in as sa and can edit anything.
The issue here is that all the user databases are shown and can even be edited. I created this instance in an effort to hide databases from whoever is not supposed to see.I was expecting a clean instance with only the system databases..Is there something that can be set to keep each instance's databases private into itself?
im trying to measure the amount of CPU used in a backup and restore, using the SQL Server Databases: Backup Restore counter in Perfmon.
I can select The counter, but it does not let me select an instance database to monitor.

I have 3 instances on my machine, 2 sql 2005 and 1 sql 2008. why do these instances not appear? i dont know how to set up this monitoring.
if i type LOCALHOST or 127.0.0.1 in the "Select counters from computer" text box i can see all databases under my sql 2005 instances, but not the ones under the 2008 instances. I have disabled all sql server 2005 services and can confirm none of the sql 2008 instance databases are showing up.
this is a huge problem, especially for when i start stress testing sql server 2008 in preperation for upgrading.
anyone any ideas on why i cannot see sql server 2008 instances in perfmon? I have tried from a remote pc also with the same results.
SQL Server 2012: Out of all the databases in the instance we have a requirement in which we need to maintain a high availability for the databases around (128). Our team believed log shipping will apt for this requirement but not sure on it's limitations, how many databases are allowed or supports this log shipping from a single instance.
I want to get all databases with it's owner Name ,I think I need to join following script result with sys.databases or sys.sysdatabases.I want a result set like this:
DatabaseName db_Owner
master sa pubs valia pubs eli pubs maryam AdentureWork eli
this script get all owners of the database that is in use:
Followed this article to move my model and msdb databes but I think I messed up. http://msdn.microsoft.com/en-us/library/ms345408.aspx The instance will not start because it says one of the files does not match it's primary file (not sure if it's model or msdb)
I can bring the instance up in single user mode (NET START mssqlserver /f /t3608) but when I try to do a query to re-do my alter statements, it says i can't attach because only one seesion is allowed. in 2000 i used to be able to start query analyzer without starting enterprise manager..
When i try and start with a minimal config (sqlservr -c -m) it won't start. I get an error saying that one of my files does not match it's primary file (either model or msbd don't know which) any ideas????????
In our production we have a database by name MyDb.The application team wanted another database by the name MyDbOld which contains the data of Mydb 1 month old. So I created a database MyDbOld in other instance(test) and restored MyDbOld from the one month backup of MyDb in production server. In test instance I backed MyDbOld as MyDbOld.bak...
In the production instance I created a new DB by the name MyDbOld and restored the MyDbOld in the production from the backup of MyDbold.bak in the test instance. Now I have 2 databases in the production instance ie MyDb and 2)MyDbOld. However I find the logical names of both the databases to be the same although the database name and the physical file name to be different.My questions are-:
1) Does it in any manner affect the integrity of the 2 databases if the 2 databases are in the same instance and have the same logical name? 2) Would the dml or data retrieval operations in the 2 databases have any conflict in any manner what so ever? 3) Having a unique database name, and unique file names for the physical files for any database in an instance what is the purpose and significance of additionally having a logical name for a database? 4) Which I could restore a database from the backup of another database in the same instance and at the same time change the logical and physical name of the files to correspond to the new database.
I need to do a inner join on tables from two separate databases. I understand that you can do this by using this type of syntax: select a.col1, b.col2from db1.dbo.tab1 a, db2.dbo.tab2 bwhere a.col1 = b.col2however, how do I reference the two databases in the following code? Thanks, Tim

My environment:XP Home, VWD, SQLEXPRESS.A purely local setting, no network, no remote servers. I try to do a JOIN query between tables in the membership ASPNETDB.mdf and one table in a self created 3L_Daten.mdf. After dragging the tables into the Query Design window and connecting them VWD creates this query (here I added the control declaration): <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringAspNetDB %>" SelectCommand="SELECT aspnet_Users.UserName, aspnet_Membership.Password, aspnet_Membership.Email, aspnet_Membership.PasswordQuestion, aspnet_Membership.PasswordAnswer, aspnet_Membership.CreateDate, aspnet_Membership.LastLoginDate, aspnet_Roles.RoleName, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Age, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Sex, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Area FROM [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten INNER JOIN aspnet_Users ON [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.User_ID = aspnet_Users.UserId LEFT OUTER JOIN aspnet_Roles INNER JOIN aspnet_UsersInRoles ON aspnet_Roles.RoleId = aspnet_UsersInRoles.RoleId ON aspnet_Users.UserId = aspnet_UsersInRoles.UserId LEFT OUTER JOIN aspnet_Membership ON aspnet_Users.UserId = aspnet_Membership.UserId"></asp:SqlDataSource> THIS WORKS, BUT: As you can see the database 3L_Daten.mdf is inserted with its full path, which is not feasible for deployment reasons. My question: How can I address both databases purely by their database names ? Both have been created within VWD and lie under App_Data. (I tried almost everything, I practiced with the SQL Server 2005 Management Studio Express Edition, I tried linked servers, all without success). Thank you for your consideration.

(SELECT AccountDBName FROM Config) ='Acc_mydbname_2008.dbo.'
Below query tells us if guest user is enabled or disabled in a particular database
SELECT dp.name, CASE perms.class WHEN 0 THEN 'Yes' ELSE 'No' END AS 'Enabled' FROM sys.database_principals dp LEFT JOIN (SELECT grantee_principal_id, class FROM sys.database_permissions WHERE class = 0 AND type = 'CO' AND state = 'G') AS perms ON dp.principal_id = perms.grantee_principal_id WHERE dp.name = 'guest';
Do we have a query which can also add the database name to above query output? The output must have columns with data against Name,Enabled,Database name
How to find last login date/time for user DML acitivity on databases on Instance?
Is there any way we can find our the last login date/time for databases?
Note: 1. We can find if the SQL Trace is running and store.This is not good solution 2. Audit logins off/on is also not good solution. 3. Using DMV's also not good option, if reboot sql server instance then historical values can not see.
