Left join from different database

Hi,
I had a scenario where I need to write a query that gets records from SQL Server Database but having a left join on Oracle table, I know we can achiev this through DB link between Oracle and SQL but my DB team are not willing to create DB links, Is there a way probably from Data Templates we can write a query which can call Oracle table too?

Hi
Thanks for your reply, but my situation is I do not have two queries, I have a single query which is pulling columns from SQL server based on a left join on one of the column of Oracle Table (cURRENTLY THERE IS db LINK BETWEEN TWO).
For E.g.
SELECT customers.first_name,customers.last_name from customers,orders
Where
Customers.Order_ID=Orders.Order_ID,
The situation here is suppose the Orders is in Oracle DB and Customers in the SQL Server DB, How am I gonna achieve this using BI publisher If I do not have DB link.

Data from different databases in the same report.

Hi Everyone,
I am trying to build a reconciliation report in which I need to show the data from the source and target, side by side.
Source and target are both different databases, although being oracle only
Whenever a new data model is created, it gets attached to a data source and in the report we need to choose a specific data model.
Can we have data from different databases in the same report ?

Yes, it is possible.
One way Is to use dataTemplates. There you can make queries from any number of different databases (The max I have done is 5).
It looks something like that:
<dataTemplate name="NameOfTemplate">
<dataQuery>
     <sqlStatement name="Q1" dataSourceRef="Connection1">
          <![CDATA[     select * from table1]]>
     </sqlStatement>
     <sqlStatement name="Q2" dataSourceRef="Connection2">
          <![CDATA[     select * from table2]]>
     </sqlStatement>
</dataQuery>
<dataStructure>
     <group name="RESULT1" source="Q1">
          <element name="P_FIRST_NAME" value="P_FIRST_NAME"/>
     </group>
     <group name="RESULT2" source="Q2">
          <element name="P_DATE" value="P_DATE"/>
     </group>
</dataStructure>
</dataTemplate>dataStructure is very important when you get data from different places, if you don't define those elements, then only the result from Q1 is shown.
The second possible way is to make as two different data models, each containing their own query and then set Main Data Set as concatenated SQL Data Source.
Best of luck,

Select data from different database

hi,
may I know how to select data from different database?
for example,
I've 2 databases, OracleDB and OracleAR
Connect with OracleAR in SQL*Plus
select * from OracleDB.TableName
does Oracle support this kind of query?
how can I retrieve data from other database while im connecting with
other database?

Hi,
Yes, it's possible. No, your syntax won't work.
First of all you have to define a DATABASE LINK inside the DB where you are already connected (in this case OracleAR). Read docs how to do that.
Second thing is the query. It will look like
SELECT * from TableName@<NameOfDatabaseLink>Greetings,

Single query to get data from different databases

i need to capture certain fields from certain tables in database 1 and certain fields from certain tables in database 2 into one file using a single SQL statement.
i tried searching on the net
i found that dblinks can help
but iam not sure if ill be able to create dblinks in my situation which is:
i need to get data from oracle to be copied to mysql
this is not a replication acitivity, but i need certain fields from one database and certain from the other
so what iwas thinking is, if i use an sql query to get all the fields (i need around 40) from the different oracle databases and create a singlefile with one insert per select, i can then read that file into mysql
instead of creating multiple sql queries for each table and creating separate files and eventually separate tables in mysql.
can anyone help me here?
or maybe suggest another approach.
thanks

Hi,
I think dblink is the only option available to get data from different databases. It will work for your case too.
CREATE DATABASE LINK db_link CONNECT TO user_name IDENTIFIED BY password USING 'instance_name'you must have the system privilege 'create database link' to create db links. This way you can get the required data and put it in a table in oracle. But i dont know how to put this data from oracle table to Mysql.

Help needed to insert data from different database

Hi ,
I have a requirement where i need to fetch data from different database through database link .Depending on user request , the dblink needs to change and data from respective table from mentioned datbase has to be fetched and populated .Could i use execute immediate for this, would dblink work within execute immediate .If not , could pls let me know any other approach .

What does "the dblink needs to change" mean?
Are you trying to dynamically create database links at run-time? Or to point a query at one of a set of pre-established database links at run-time?
Are you sure that you really need to get the data from the remote database in real time? Could you use materialized views/ Streams/ etc to move the data from the remote databases to the local database? That tends to be far more robust.

Select query based on joining of tables from different database is taking too long

Hi Team,
Select query on table with millions of records is taking very long time. It took 50mins, the below query is joining on multiple table from two databases DB1.dbo.Table1 contains 100 million records and also Table3 and Table4 (of different database) might
contain close to 1million records.
Select T1.*
From DB1.dbo.Table1 T1
Join DB1.dbo.Table2 T2 on RTRIM(T1.Col3) = RTRIM(T2.Col3)
Join Table4 CA on RTRIM(T1.Col1) + T2.Col2 = CA.Col1
Join Table3 U on CA.Col2 = U.Col2 AND RTRIM(T2.Col2) = U.Col3
Where U.Col4 NOT IN ('A1', 'A2', 'A3', 'A4', 'A5', 'A6','A7','A8','A9')
And (T1.flg IS NULL OR T1.flg = 'N')
And LTRIM(RTRIM(T2.Col2)) NOT IN ('B1','B2')
How can i improve the performance of this query. Actual thing is update the data in Db1.dbo.table1 based on the conditions but if the select is taking close to 1hr then update will take hours together. Indexes already implemented on all the tables.
Thanks,
Eshwar.

Thanks.
Join Table4 CA on RTRIM(T1.Col1) + T2.Col2 = CA.Col1
This join is not working with spaces if Rtrim is not used.

How to join tables from different databases (DBLink/DB connection )

Hello,
i have an issue and i hope you could help me to solve it. My problem is: I want to create native sql select which joins two tables from different DB (both of them are ORACLE, one of them internal, another one - external). I have found several notes and posts, but without any success. Db connection exists in dbcon table, so this part of my problem has been solved.
I would like something like that:
select * from table1@xxx inner join table2.
i can not split this select into two separate ones, because both tables store over 30 mln. entries and i do not want to create any copies of them.
Br,

Hi,
you might need to create a DB-Link on DB level and use EXEC SQL.

Dealing with tables from different databases?

Hi. I'm a newbie to Visual Studio 2012 and stuck on how to interact with different datasets.
I am building a report that is associated with with two tables, each from a different database. The
master_flat table with the primary key matter_number is from the first database and it contains all the columns I need that should show up in the report layout I've built. However,
billing_table with the primary key matter_number contains a flag that I go by which I must use to determine whether each matter should come through in the reporting or not.
I've set the master_flat as dataset1 and the billing_table as dataset2. Now, what is the best way in Visual studio 2012 to filter by the matters that has flag "N" in dataset2?
Thanks

We are way out of sync. Lets synchronize. I'm not sure which question you are refering to. Is it the "C# or VBnet" question or is it the "One or two database Question". It seem like it would be the database question since you
should know which programming language you are using.
Open SQL Server Management Studio (SSMS). After login, there is an explorer where you can browse the databases, tables, and fields in the tables. You should be able to view how you build the database. If you right click any tables and then
"Script Table As : Select To : New Query Editor Window". There is an execute button to run the query. You can aslo edit the query. I usually test all my qeuries in SSMS before actually using them in an application. I would get a JOIN
SQL working in SSMS.
If you let me know if you are using VBnet or C# I will write a simple LINQ. Even better if you supply me the names of the columns of the two tables.

How to migrate files from different databases to sharepoint 2013?

Hello everyone,
I need to migrate files of various formats from two databases to SharePoint 2013 ? How should I pursue? Please explain..
Scenario : Two different databases on different systems have loads of files. I need to migrate them to SharePoint?
Any suggestions/ Answers

Hi,
You need to copy the database into your network shared folder or SharePoint Server where you wanted to attach this content DB to your newly created web application.
Hope and Afraid,
Same Domain has been used. I mean if you move the content db from the server 1 which using the AD1 for authenticate the users,
So your new server 2 and web application must have configured to authenticate the AD 1 users.Otherwise user not found exception will be thrown.
If not still you can change the site collection administrator for the site which is migrated from the server 1.

Database restore from different Database Sid

I have installed sap ecc6 sr3 on db2 version 9.1 fp5 which is running on WIn2003 Enterprise x64 edition which is working fine. It is my Quality server Database Sid Q11.
Now i want to restore database from Development server D11 (offline backup) to quality server Q11.
Development server database Sid is D11.
How to restore from Different Sid. (In DB2 database).
Please tell me how to restore database from another Sid.

Hi,
what you have to do is a so called "redirected restore".
The recommended way to that in an SAP-DB2 environment, is to use the tool brdb6brt shipped together with the SAP kernel. For details how to use this tool refer to the DB2-UDS Database Administration Guide.
kind regards

Restore RMAN from different Database Rman backup

Hi Everybody
I am practicing Rman so I have one query that how to restore rman backup from another database.
For Example :
1. I have Rman backup of DB1 with level 0 and level 1 cumulative database plus archievelog
2. I need to import or restore Rman backup of DB1 to another database DB2.
What is the procedure for doing the above queries. Please anyone one help me out.
I have using oracle 10g r2 running in windows server 2003.
Thanks in advance.

These are the steps ; you need to write the appropiate commands for each step: Hope it helps!
1) Take appropriate RMAN backup of the database db1. Note that you should turn on the CONTROLFILE AUTOBACKUP configuration so that we have the controlfile backed up after the database backup. When we restore the controlfile on new host from this autobackup piece, it will have the information of the latest backup.
2) Create a PFILE for the destination database db2 using the database db1
3) Move the backup pieces and the modified INIT.ORA file to the new host. Starting from 10g it is NO longer compulsory to copy the RMAN backup pieces to exactly the same location on the new host as the production location.
4) Use the pfile created above to STARTUP NOMOUNT the database on the new host
5) Now invoke RMAN and restore the controlfile specifying the location where the controlfile autobackup piece is restored on this new server. You can mount the database once the controlfile is restored successfully.
6) You can skip this step if you have restored the RMAN backup pieces to exactly the same location they were backed up on database db1. If this is not the case then you need to catalog the RMAN backup pieces to make RMAN aware of thier new location on the new host. Note that CATALOG BACKUPPIECE command is available only starting from 10g.
7) Having determined the point up to which media recovery should run, start the restore/recovery using for example:
RMAN> run {
2> set until sequence 59 thread 1;
3> set newname for datafile 1 to '/new_location/system01.dbf';
4> set newname for datafile 2 to '/new_location/undotbs01.dbf';
5> set newname for datafile 3 to '/new_location/sysaux01.dbf';
6> set newname for datafile 4 to '/new_location/users01.dbf';
7> restore database;
8> switch datafile all;
9> recover database;
10> }

Hi,
I have a Subject Area which is built on Essbase cube. I have a requirment where I have to use a Lookup on Flat file and/or Database Table.
I followed below steps
1. Created a Logical Column in BMM Layer for a cube dimension
2. Opened the LTS Properties --> Column Mapping and gave below formula
Lookup(SPARSE "Function1"."E:\502125500".""."Function2.txt"."ALIAS", 'NA', "TNWD06613.genpitfi01.og.ge.com"."GOGREP".""."GOGREP"."Gen5,Functions" )
where
Function1"."E:\502125500".""."Function2.txt"."ALIAS" ---> Column from File (Created File DSN and imported in RPD)
"TNWD06613.genpitfi01.og.ge.com"."GOGREP" ---> Essbase Cube
3. Dragged the Column to Presentation for Subject Area on Cube
When I try to create a report on this column I get below error.

Can anybody help me on the same?

You can script schemas from all DBs and in case of conflicts you will have to decide what to do.
For example if you have the same SP or UDF on two DBs that does different things, you need to decide what to do with them.
Only if the conflict is tables with the same structure and without KEY constraints and you can also script data and go on.
If you have PK-FK relationships (which I bet is the case) you really need to design your changes based on them and I suspect you will end up scripting instead of putting boxes on SSIS.
It really is a migration job for an experienced DBA and am afraid SSIS can do that much as
Integrate.. not Migrate.
