Query multiple database

Hi ALL
I have two databases A and B.
I am working in database A but want to fetch some record from a table which is in database B.
I am using a select query like
select max(end_dt) from log
This log table is in Database B
Please give any suggestion.
Thanks

create a database link on the A database to link to database B:
CREATE DATABASE LINK DB_B
CONNECT TO scott IDENTIFIED BY tiger
USING 'Bl';Then on A you can query the log table on B:
SELECT max(end_dt) FROM log@DB_B;The user that creates the database link on A will need the CREATE DATABASE LINK system privilege.
grant CREATE DATABASE LINK to userOnA.

Questions about Oracle 9I AS, reports.... to query multiple database

Hi friends,
I am working for the HR dept of a big company and our
group will implement some enviornment to present HR reports for the leadership through web interface.
I have checked the Oracle 9iAS page and it seems it is
a pretty nice tool. The reports service is very impressive. We mainly use Java/JSP to do the project,so
this Oracle9i can fit our development team. One of
the problem is that we have multiple databases running
on different machines,including Oracle 7, Oracle 8i and
SQL Server 2000. So, one of the requirements is to query
multiple databases of different verdors.
So my question is:
can Oracle9i AS (especially the reports service) do this
multiple database query? I know with pl/sql, we can create
database link to do this query, but can we do it in
reports tools?

Yes you can do Even in the reports.

Querying Multiple databases on Azure SQL

Does anybody know if there is a way to query multiple Azure sql databases in a query?
I have tested the query on a standard sql server I have setup here and that works fine.
I believe Azure does not support cross database queries and you have to do an elastic database query. Any ideas how this works?
This topic first appeared in the Spiceworks Community

Hello. We currently have a database cluster that has a WSUS database on it. We wanted to setup another WSUS server in our environment, is this possible? I have read some posts saying that there was a 1 to 1 for WSUS DB to SQL Instance
but those were from 2008 and 2011 and I am wondering if it is possible today. If not, what would be the recommendation? Another SQL Instance or just use the Windows Internal Database.
There is still a limitation of 1 WSUS to 1 SQL Instance, because the database name is hardcoded to SUSDB. To use multiple WSUS servers on that same cluster will require the installation of an additional instance.
If that additional server is destined to be a downstream server, though, I would recommend just using the native Windows Internal Database on the local system.

How to define a JPA "Entity" used to query multiple database tables

While using JPA to access database, I have a need to define a generic "Entity" class to use for query different tables. The reason is I have a lot of non-business tables (reference tables) I need to query. I intend to use Native SQL to do the query. Most query will only return 1 - 3 columns. It is tedious to define many JPA entities only to use them sparsely.
For example, if I have two Native query, and define a JavaBean that has 3 properties, how do I implement this in JPA?
Thanks for your help.
query 1:
select LASTNAME as f1, AGE as f2 from PERSON
query 2:
select zipcode as f1 from LOCATION
package model.uti;
public class SimpleBean {
private String f1;
private String f2;
private String f3;
public SimpleBean() {
public void setF1(String f1) {
this.f1 = f1;
public String getF1() {
return f1;
public void setF2(String f2) {
this.f2 = f2;
public String getF2() {
return f2;
public void setF3(String f3) {
this.f3 = f3;
public String getF3() {
return f3;
}

An @Entity is mapped to a specific table. You can't fill it with totally random data from a collection of tables.
If you want to access data from multiple tables within the one entity, then the JPA spec defines an annotation @SecondaryTable, which allows you to specify a
second table and the join condition.
http://java.sun.com/javaee/5/docs/api/javax/persistence/SecondaryTable.html
The JPA spec talks about this as do most good EJB/JPA books.

Multiple databases in a single query

I need to query multiple databases in a single query.
e.g.
Database d1 contains table t1 with column id
Database d2 contains table t2 with column id
I need a query like
SELECT * FROM t1, t2 WHERE t1.id = t2.id;
is this possible in jdbc? if yes can anyone help with some sample code?
thanks,
Ashish Saraf

It is not possible using the JDBC API to query tables in two or more databases using a single query. The reason is that a JDBC Connection is made to a single data source.
However, some databases support the idea of federations or linked tables. What you do is inside the database manager link or federate a table that is present in another DBMS. Then, pose a single JDBC query to the one DBMS which will have its own table and links to the external tables.
Another approach is to use a special JDBC driver with a built-in integration engine that will perform a query across multiple databases. In effect, the system poses separate queries to the different databases and integrates and joins the data together for you automatically on the client-side. That is much easier than doing it yourself in code, but that is also possible for simple queries.
As part of my research program, we have released a shareware version of the UnityJDBC driver that can query multiple databases using a single SQL query. For more information, see:

Need to get data from multiple database instances in a single query

Hi,
I need a small favour from you guys. The prob is as follows:
I need to get name, row_id from table A from schema 1 and gbu_name, name from table B from schema 2 where a.name = b.name. I wrote the query in the following manner:
SELECT a.name, a.row_id, b.gbu_name
FROM Schema1.A as a, Schema2.B as b
Where a.name = b.name
But this query is not working and the error is like " The table does not exists".
Please update me how to avoid the error and get the right sort of result.
Thanks & Regards,
Debabrata

Ah, youre actually asking different things.
In your topic title, you say youre running separate instances
In your body text, you say you are under different user/schema
So tell me, do you have more than one database or not? How many entries in your TNS file?
I would say, for "multiple database instances"
SELECT
a.id, b.id
FROM
tableA a
INNER JOIN
tableB@OTHER_DATABASE_LINK_NAME b <--NOTE!
USING(id)And of course you will have to look up CREATE PUBLIC DATABASE LINK sql..

SELECT query from multiple databases

Hi,
Is it possible to run a SELECT query using multiple DBs' tables, like outer joining them. One of the DBs is Sybase.
Thanks in advance

A TopLink session can span multiple databases if they can be accessed through a single connection. A single select would require the database to handle the aggregation as mentioned in the other post.
Alternatively TopLink's session broker will support making a single session present persistent types from multiple independent databases. This approach will not support a single SELECT spanning the databases though.

Query multiple rows

Hi, need some help on XML and XSD.
say I have a table in the database with 3 columns: a, b, c
on my XDP form, I have a table, like a spreadsheet, with 3 columns too: x, y, z
and it has 10 rows.
I want to pre-fill the form with 10 rows of data,
so, in my Process's action profile,
I use JDBC's query multiple rows to get the first 10 records of my database table.
how do I put these 10 rows of data into the table on my form?
TIA for helping me.
Happy New Year!

Step1: Use SQL Query Multiple results as XML activity
Step2: Define the output of SQL activity to look similar to
<table>
    <row>row1 value</row>
    <row>row2 value</row>
    <row>row3 value</row>
    <row>row4 value</row>
    <row>row5 value</row>
    <row>row6 value</row>
    <row>row7 value</row>
    <row>row8 value</row>
    <row>row9 value</row>
    <row>row10 value</row>
</table>
Step3: arrange your forms fields (Table and rows) in the same way as mentioned above.

How to access multiple database present in single instance

Hi Team,
In oracle 11.2, can there be multiple databases in an instance??? In one of our environment, I could see multiple databases in an instance. Could you please help me in giving the data dictionary or query to access those databases?
Actually, querying v$database, I could see only one database which is same as instance name. But in inventory, there are multiple database in an instance?
I am still not exactly clear about this. Can someone help me with this?
Thanks!
Vidhya

In Oracle one instance manages one (1) database. A database consists of multiple *schemas*.
Other vendors erroneously call a schema 'database'.
So, no, you didn't see multiple databases.
There is also one datadictionary, consisting of a set of views.
All views beginning with dba_ list the entire database, all schemas.
All views beginning with all_ list the objects you have access to.
All views beginning with user_ list your own objects.
The view DICT show you the contents of the datadictionary.
Oracle also has online documentation at http://docs.oracle.com
From your question it is clear you should read the document called the 'Oracle Concepts Manual'.
You can find all documentation for 11gR2 here Oracle Database Online Documentation 11g Release 2 (11.2)
Too many people here don't make any effort to read it. This is probably the reason why you got no response.

Can join queries in Oracle 8i and above span multiple databases

Hi,
In Oracle 8i and above, can join queries span multiple databases??
For eg., I have two databases A and B, and say database A has table A_T and
database B has table B_T. Assume that both the databases are on the same
server.
Can I run a join query from my application using OCI calls that spans across
tables from multiple databases, namely, A_T and B_T?
My query probably looks like this - Select * from A.A_T, B.B_T;
Thank you,
Sashi

select * from A.A_T, B.B_T@dbB where A.A_T.PK = B.B_T.PK@dbB
The Oracle manuals should have the information you need on creating a database link.

Multiple database users, ORM, entity framework, best practices

Hello everyone!
You've already helped me several times, however I must ask for an advice once more.
I was assigned to develop .NET application with Data Access Layer and I've decided to use Oracle Database Software to provide sample data.
As I'm absolute novice considering creating DAL I'd be grateful if you can examine my plan in terms of security and reliability:
My database:
1) I've created database with sample tables and relations between them. All tables belongs to databaseAdmin.
2) I've created HR and Manager database users and granted them some privileges on certain databaseAdmin's tables. My intention is to reduce access to unnecessary tables. If my application user want to make some changes to Customers table it should be enough to connect to database as HR.
And now I'd like to map my database using Entity Framework in my application. And that's where I have a problem:
-If I create Entity Model basing on databaseAdmin tables I get perfect model, however every Entity SQL query would be executed on behalf of databaseAdmin, which breaks my idea of hiding unnecessary tables.
-If I create Entity Model for HR and Manager users, my models could overlap on tables that both users have access to and no connection between tables would be generated (as from their point of view those tables are just some tables that belong to databaseAdmin)
Could you help me with this deadlock? Or maybe my assumptions about multiple database users are incorrect? Please, bear in mind I'm a novice.
I was trying to find a solution in web, and there're tons of data discussing technical aspects of Entity Framework etc., but not so many documents about conceptual model of database.

hi Michael,
Thanks for you posting!
Sorry for I am not totally understanding your issue. Maybe two points need your confirm:
1. I confuse with the "Service controller"? IS your meaning MVC controller? Or ServiceController(http://www.codeproject.com/Articles/31688/Using-the-ServiceController-in-C-to-stop-and-start
2.whether The type of ID in the model is match to the database ? In other words, Is the type of IDin .edmx matched to the database?
By the way, it seems that this issue is more related to EF. You could post this issue on EF discussion for better support.

Using Single Datasource to Access Multiple Databases

Hi,
We would like to know the pros and cons of accessing multiple
databases through a single datasource, versus accessing each
database through its own datasource. Our environment includes
multiple web servers w/ the latest version of ColdFusion MX 7,
clustered through a load balancer. Each web server has 800+ dsns
pointing to different SQL databases on the same SQL server. We have
noticed that the ColdFusion administrator is taking a long time to
display or verify all datasources and sometimes it even times out.
Another problem is that sometimes the neo-query file gets corrupted
(for unknown reasons) which results in the deletion of one, or
more, or all datasources on the web server.
Because of the issues above we are researching the
possibility of removing most of the datasources, and then accessing
each database through a single bridge datasource. In that regard we
plan to change our queries by inserting the sql db name and user in
front of each table in the query such as:
<cfquery name="query" datasource="single_dsn_name">
select * from [#dbname#].dbo.tableName
</cfquery>
In the example above, obviously #dbname# would be a variable
that will hold the name of the requested database. The code above
would similarly apply to queries using, update, insert and join
words.
Are there any limitations or negatives from scalability,
performance, and reliability perspective in implementing the above
scenario versus having one datasource for each database.
Also, if there is a better way of accomplishing this, we
would love to hear about it.

Here is my opinion, because I work with both schemas. The
main advantage to use one datasource for all DBs in a SQL Server is
the simplicity of administration.
But the main disadvantage is security, because you are using
a single user to access all DB in a server, you don't have
isolation, and a user that knows your schema can access data of
other DBs that he sould not be authorized.
Another issue is is a user must access 2 differents DB with
different permissions (a DB only read and the other read/write),
you'll have to create another datasource, user, etc for it.
But the decision depends in the enviroment. If you are a
hosting company, I would use 1 datasource for user or DB. If the
servers and DBs are of the same company, I could use one datasource
for each SQL server.
Best regards

Outer joins across multiple databases

I'm trying to join three tables: 2 from data warehouse and 1 from Siebel database in OBIEE. I create the physical and logical joins (no errors or warnings). The model looks like this: Account Address (table 1) -> Account (table 2) -> Siebel Customer Data (table 3)
I create two queries in Answers:
(1) Account.Number and Siebel.Address (the query works)
(2) Account Address.Zip, Account.Number, and Siebel.Address (the query gets the following error):
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 42019] Join condition, D901.c3 <> 0, contains predicates that are currently not supported for outer joins across multiple databases. (HY000)
Can someone help me understand why the join between the two databases works for the first query but when I add a second table it fails?
thanks...

Either you can link the Oracle DB into Access (by using File/Get External Data/Link Tables)
or you have to simulate the join in Java by doing two separate queries and looping through the results.

Avoiding WITH clause when querying Multiple Facts

OBIEE 10.1.3.4
We have a report which requires that we query multiple facts, which share the same Item dimension.
When we run the report, the BI Server generates a query using the WITH clause -
WITH SAWITH0 ( SELECT.............)
SAWITH1( SELECT .............)
SELECT .........
FROM SAWITH0 FULL OUTER JOIN SAWITH1
The above query errors out with ORA-918 Column Ambiguously Defined. I cannot find any issue in the query that has been generated.
The query does fail from SQL Plus with the same ORA error. But each of the select statements executed properly and the complete statement executes when I replace the FULL OUTER JOIN with INNER JOIN.
I can only assume that this is a bug in Oracle Database.
Now at times I have seen OBIEE generate separate queries when querying multiple facts and then combine the data together in memory.
Is there a way that I can force OBIEE to avoid using WITH clause and run separate SELECT statements ? How does the BI Server choose between using a WITH clause or running separate queries ?
Any help would be appreciated.

I do not have a multi-dimensional data source.
My connection pool seems fine to me, I am not sure I need to do anything with the connection pool.
Hi Turribeach,
I understand that BI Server uses WITH clause for multiple facts. But I have also seen it issue separate queries against the database.
So what I am looking to understand under what situation does it issue separate queries i.e. No WITH clause ?
Thanks

Multiple Database Links

I have created a database link in Oracle 9i to access the data stored in a remote MSSQL Server machine. Can I create multiple database links in Oracle 9i to access different remote MSSQL Server machines? If yes, please advise how to accomplish this. Thanks.

From A, you can query synonym on B linked to table on C. Then grant select on this synonym to user user used for the dblink connection.
