View Between Tables In Different Databases
Jun 25, 2007We have created a view that selects from tables in two databases. it looks like something like this:
CREATE VIEW myview AS
SELECT col FROM db1.mytab
UNION SELECT col FROM db2.mytab;
Both tables have col as primary key.
When we executes SELECT col FROM myview WHERE col='SOMEVALUE' we receives the correct result but SQL server does not use any indexes. It performs a index scan on both tables. Wh and what can we do about it? The tables contains millions of rows so the performance is terrible.
The following works fine:
SELECT col FROM db1.mytab WHERE col ='SOMEVALUE'
UNION SELECT col FROM db2.mytab WHERE col ='SOMEVALUE';
Qe are running SQL Server 2000 and TRANSACT SQL

SQL 2012 :: Partitioned View Over Two Databases
Sep 8, 2014I have database with a large table (30 Billion rows) because it is so big I separated the data in quarterly tables and created a partitioned view (with hints for the date column) about 1 billions a quarter. (all in separated filegroups). The tables themselfes are partitioned by date again, so you slice out one day
However the full-backup of grows and grows and the mainpart of it is "old" but needed data.
So I was thinking to put the older data in a separate database (with separated backup) and then point to the table in my view.
While this is technical possible (leaving out the WITH SCHEMABINDING) I wonder what negative consequences it will have.
I already had to lose "with schemabing".
I have to use separate partioning functions - for each database its own - (partition schemas where already separated due to separated filegroups)
What about query optimization, does the optimizer care that there are two databases?
Mirroring Databases Connected Through A View
Oct 12, 2006I have two databases db_A_primary and db_B_primary, both databases are on one Primary server.
db_B_primary has a View into db_A_primary.
Scenario: db_A_primary goes down and failsover to db_A_mirror on the Mirror server.
In this scenario when the View in db_B_primary is accessed will it automatically be redirected to look at the db_A_mirror database on the Mirror server?

Alternative To Creating View With Union In Two Databases?
Jul 20, 2005I attempted to create a view in SQL Server 2000 that Unions twoqueries. The first part of the query gets data from the local server,the second part gets info from a linked server. (The query works finein Query Analyzer.)I received this error when I tried to save the query:ODBC error: [Microsoft][ODBC SQL Server Driver] The operation couldnot be performed because the OLE DB provider 'SQLOLEDB' was unable tobegin a distributed transaction.[Microsft][ODBC SQL Server Driver][SQL Server][OLE/DB providerreturned message: New transaction cannot enlist in the specifiedtransaction coordinator.]After a little reading I discovered the "Database limitation":"A view can be created on a table only in the database the viewcreator is accessing".That's my problem... is there a simple solution or alternative tocreating a view?Thanks,Matt
View 2 Replies View RelatedPermissions With Windows Groups And View To Other Databases
Aug 24, 2007I am having a problem with permissions using Windows groups. I have a database (database1) that has permissions granted via Windows groups. Two groups (group1 and group2) are members of the db_datareader role in database1, and this work fine. Do to the number of tables that get created during our work, using db_datareader is the easiest way to keep up with permissions without creating a maintenance problem. Now I have a table that I want to add to this database, but I only want group2 to have select permission on this one table which is a problem because group1 has the db_datareader role. So I thought I could create a view in this database to the restricted table that I put in database2. Then in database2 I only added group2 as a user with the permission to select from this table. Unfortunately the group membership does not seem to get interpretted correctly in database2 and no one can successfult select from the view in database1.
In other words, user1 who belongs to group1 connects to database1 and cannot select from the restricted view -- this is what I would expect. However, when user2 who belongs to group2 connects to database1 they also cannot select from the restricted view -- not the behvior I would expect. Now, if I make user2 a user in database2 with select on the restricted table then user2 can connect to database1 and successfuly get data from the restricted view. So it looks like the fact that user2 belongs to group2 is never passed to database2 via the select from the view on database1. Is this indeed the way that Windows group security is working or is meant to work in SQL Server?
I realize I could solve this simplified version of the problem by creating my own role in database1 for group1 etc., but I am trying to solve a bigger problem in our environment that has hundreds of databases across numerous servers.
Thanks

View Of Multiple Databases With Identical Schemas
Aug 24, 2006I 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?
SQL Server 2008 :: Create View For Each Table In The Databases?
May 27, 2015We have two databases with same schema and tables (same table names, basically main DB and a copy of the main DB). following is example of table names from 2 DBs.
CREATE TABLE #SourceDatabase (SourceColumn1 VARCHAR(50))
INSERT INTO #SourceDatabase VALUES('TABLE1') , ('TABLE2'),('TABLE3') , ('TABLE4'),('TABLE5') , ('TABLE6')
SELECT * FROM #SourceDatabase
DROP TABLE #SourceDatabase
CREATE TABLE #ArchiveDatabase (SourceColumn2 VARCHAR(50))
INSERT INTO #ArchiveDatabase VALUES('TABLE1') , ('TABLE2'),('TABLE3') , ('TABLE4'),('TABLE5') , ('TABLE6')
SELECT * FROM #ArchiveDatabase
DROP TABLE #ArchiveDatabase
We need a T_SQL statement that can create one view for each table from both the databases(assuming both databases have same number of tables and same table names). so that we can run the T_SQL on a thrid database and the third DB has all the views (one view for each table from the 2 DBs). and the name of the view should be same as the tables name. and all 3 DBs are on the same server.
the 2 temp tables are just examples, DBs have around 1700 tables each. so we ned something like following for each table.
CREATE VIEW DBO.TABLE1 AS SELECT * FROM [SourceDatabase].[dbo].[TABLE1] UNION ALL SELECT * FROM [ArchiveDatabase].[dbo].[TABLE1]
CREATE VIEW DBO.TABLE2 AS SELECT * FROM [SourceDatabase].[dbo].[TABLE2] UNION ALL SELECT * FROM [ArchiveDatabase].[dbo].[TABLE2]
CREATE VIEW DBO.TABLE3 AS SELECT * FROM [SourceDatabase].[dbo].[TABLE3] UNION ALL SELECT * FROM [ArchiveDatabase].[dbo].[TABLE3]
CREATE VIEW DBO.TABLE4 AS SELECT * FROM [SourceDatabase].[dbo].[TABLE4] UNION ALL SELECT * FROM [ArchiveDatabase].[dbo].[TABLE4]
CREATE VIEW DBO.TABLE5 AS SELECT * FROM [SourceDatabase].[dbo].[TABLE5] UNION ALL SELECT * FROM [ArchiveDatabase].[dbo].[TABLE5]
CREATE VIEW DBO.TABLE6 AS SELECT * FROM [SourceDatabase].[dbo].[TABLE6] UNION ALL SELECT * FROM [ArchiveDatabase].[dbo].[TABLE6]

Alter View / Create View
Aug 14, 2000I had given one of our developers create view permissions, but he wants to also modify views that are not owned by him, they are owned by dbo.
I ran a profiler trace and determined that when he tries to modify a view using query designer in SQLem or right clicks in SQLem on the view and goes to properties, it is performing a ALTER VIEW. It does the same for dbo in a trace (an ALTER View). He gets a call failed and a permission error that he doesn't have create view permissions, object is owned by dbo, using both methods.
If it is doing an alter view how can I set permissions for that and why does it give a create view error when its really doing an alter view? Very confusing.
Updating My View Changes My View Content

FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
When ever I open using SQL Entreprise manager to edit it by adding or removing a field i inserts Expr1,2.. and I don t want that. The result I get is:
SELECT dbo.Lk_Feat.Descr AS Expr1, dbo.Lk_Feat.Price AS Expr2, dbo.Lk_Feat.Code AS Expr3, dbo.SubFeat.SubNmbr AS Expr4
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
I don t want Entreprise manager to generate the Expr fields since I use the real fields in my application.

View Works, But The Sql From The View Does Not
Oct 27, 2006I was looking through our vendors views, searching for something Ineeded for our Datawarehouse and I came across something I do notunderstand: I found a view that lists data when I use it in t-sql,however when I try to use the statement when I modified the view (viaMS SQL Server Management Studio) I can not execute the statement. I getThe column prefix 'dbo.tbl_5001_NumericAudit' does not match with atable name or alias name used in the query.Upon closer inspection, I found two ON for the inner join, which I dontthink is correct.So, how can the view work, but not the SQL that defines the view?SQL Server 2000, up to date patches:SELECT dbo.tbl_5001_NumericAudit.aEventID,dbo.tbl_5001_NumericAudit.nParentEventID,dbo.tbl_5001_NumericAudit.nUserID,dbo.tbl_5001_NumericAudit.nColumnID,dbo.tbl_5001_NumericAudit.nKeyID,dbo.tbl_5001_NumericAudit.dChangeTime,CAST(dbo.tbl_5001_NumericAudit.vToValue ASnVarchar(512)) AS vToValue, dbo.tbl_5001_NumericAudit.nChangeMode,dbo.tbl_5001_NumericAudit.tChildEventText, CASEWHEN nConstraintType = 3 THEN 5 ELSE tblColumnMain.nDataType END ASnDataType,dbo.tbl_5001_NumericAudit.nID,CAST(dbo.tbl_5001_NumericAudit.vFromValue AS nVarchar(512)) ASvFromValueFROM dbo.tbl_5001_NumericAudit WITH (NOLOCK) LEFT OUTER JOINdbo.tblColumnMain WITH (NoLock) INNER JOIN---- Posters comment: here is the double ON--dbo.tblCustomField WITH (NoLock) ONdbo.tblColumnMain.aColumnID = dbo.tbl_5001_NumericAudit.nColumnID ONdbo.tbl_5001_NumericAudit.nColumnID =dbo.tblCustomField.nColumnID LEFT OUTER JOINdbo.tblConstraint WITH (NOLOCK) ONdbo.tblCustomField.nConstraintID = dbo.tblConstraint.aConstraintID AND(dbo.tblConstraint.nConstraintType = 4 ORdbo.tblConstraint.nConstraintType = 9 ORdbo.tblConstraint.nConstraintType = 3)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CAST(CAST(vToValue AS decimal(19, 6)) AS nVarchar(512)) ASvToValue,nChangeMode, tChildEventText, 5 AS nDataType,nID, CAST(CAST(vFromValue AS decimal(19, 6)) AS nVarchar(512)) ASvFromValueFROM dbo.tbl_5001_FloatAudit WITH (NOLOCK)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CAST(vToValue AS nVarchar(512)) AS vToValue, nChangeMode,tChildEventText, 2 AS nDataType, nID,CAST(vFromValue AS nVarchar(512)) AS vFromValueFROM dbo.tbl_5001_StringAudit WITH (NOLOCK)UNION ALLSELECT aEventID, nParentEventID, nUserID, nColumnID, nKeyID,dChangeTime, CONVERT(nVarchar(512), vToValue, 121) AS vToValue,nChangeMode,tChildEventText, 3 AS nDataType, nID,CONVERT(nVarchar(512), vFromValue, 121) AS vFromValueFROM dbo.tbl_5001_DateAudit WITH (NOLOCK)

Selecting A View And Selecting FROM A View Is Wildly Different
Feb 21, 2006A colleague of mine has a view that returns approx 100000 rows in about 60 seconds.
He wants to use the data returned from that view in an OLE DB Source component.
When he selects the view from the drop-down list of available tables then SSIS seems to hang without any data being returned (he waited for about 15 mins).
He then changed the OLE DB Source component to use a SQL statement and the SQL statement was: SELECT * FROM <viewname>
In this instance all the data was returned in approx 60 seconds (as expected).
This makes no sense. One would think that selecting a view from the drop-down and doing a SELECT *... from that view would be exactly the same. Evidently that isn't the case.
Can anyone explain why?
Thanks

Two Databases
Sep 24, 2006I have created a site which now has two databases. Firstly is the ASPNETDB.MDF which I beleives get set to manage the security, logon/Roles that I have on my site. The second dataabase "MyDatabase" is one that I have created for all my data withing the site. I would like to combine this to one Database for simplicity and cost. Now I can't see the ASPNETDB.MDF when I use SQL Manager 2005 and I can't see how to change the set up of ASP.Net Configuration if I was to just use mydatabase. Any suggestions

Sep 25, 2006Hi, I have my site set up, but have had difficulty using the data gathered by the aspnet.mdf. I wanted to use the email and username columns from the membership table to send newsletters automatically from the database(but that's a whole other post)I also have my own databse, which will be populated by information gathered from the website, so is currently empty. I'd like to take this opportunity to say that i don't think there's enough information given on how to populate a blank database from a website application. Most tuorials etc are concentrated on retrieving and displaying data, which is all well and good, once you actually have data to play with!I don't need two databases, so can I add tables to the aspnet.mdf ? But then what about relationships etc? I won't damage the current relationships by adding new ones? On the other hand can i copy the aspnet.mdf into my own database, and then assign the relevant permissions to that db? Any help would be greatly appreciated-in language for newbies please! I am relatively new to .asp.net/Visual Basic/ and SQL. It's a steep learning curve!Also....I have used create user wizard, login, password recovery etc within my site, the data is inserted into the correct db tables-without using an sql datasource for some reason...? is that right?I have also created a wizard to collect some more data (because i couldn't work out how to insert the data from the extra steps in create user wizard, into my own database) but when i click submit the data is not inserting into the specified table - (yes the connection string is fine, insert and update has been selected from the advance tab in connections wizard). Would this/could this be because i have assigned a 'finishbutton url'? should i use a Response.Redirect("blahblah.aspx") instead?

Use 1 Or 2 Databases?
Jul 16, 2000Hello,
I’m using VB6 as the client and MS SQL Server 7 as the database. The company I’m consulting for has a proven track record for marketing and getting millions of customers. The parent company would like to create two new companies selling the same product; with 1 million customers per company. How many records can MS SQL Server 7 handle? I’ve been told it can handle 4 terabytes. What does 4 terabytes translate into records? I have already set up an application for company #1. Should I put company #2 in the same MS SQL Server database? Or should I put company #2 in a different database? My VB Application and SQL Server database were designed to handle multiple companies selling the same product. For performance sake; would it be better to separate the databases? Any suggestions? Is anyone currently using MS SQL Server with 2 or more million records?
Thanks,
Denise
