SELECT data from two databases

I have two databases that I need to select data from in a
single SELECT. Using DWs Advanced window for creating the select I
don't see any way to select more than 1 Connection. Both databases
have unique user and passwords but reside on the same server. Any
idea how I can write a single SELECT to get data from both dbs. I
assumed it would be similar to selecting data from multiple tables
within the same db but the connection part is stumping me. Any
ideas would be greatly appreciated.

That's the basic technique for joining two tables in the same
database.
The original poster has tables in different databases that
have
different user accounts and passwords.
Although it's possible to join two databases, you cannot do
it unless
you have one user account with the same privileges on both
databases.

WHERE pspnr in p_no and prpspsphi = projpspnr.
but there is error in from clause ..please help me....
Advance thanx....

Hi,
check the sample code bellow above two reply will solve out your problem but one more extra line in your code pointed out bellow.
TABLES: prps, proj.
TYPES: BEGIN OF ty_test,
        pspnr LIKE prps-pspnr,
        objnr LIKE prps-objnr,
        psphi LIKE prps-psphi,
        ernam LIKE proj-ernam,
        erdat LIKE proj-erdat,
        END OF ty_test.
DATA: itab TYPE STANDARD TABLE OF ty_test WITH HEADER LINE.
SELECT-OPTIONS: p_no FOR prps-pspnr.
SELECT prps~pspnr
        prps~objnr
        prps~psphi
        proj~ernam
        proj~erdat
*        proj~pspnr " No need for this you have selected this in
*     the first line because it is commone so you only need to select from any one
        INTO TABLE itab
FROM prps INNER JOIN proj ON ( prps~pspnr = proj~pspnr )
WHERE prps~pspnr IN p_no.

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,

Selecting data from two tables

I am trying to select data from two tables. The only problem that I am running into, is that i am only seeing results from my 'uploads' table. there is also a record in documents where user = 1 that should show up. here is my sql:
$userIDNum = 1;
$sql="Select *
from uploads, documents
WHERE uploads.user = documents.user AND uploads.user = $userIDNum
ORDER BY uploads.title ASC, documents.title ASC";

You'll need to explain a little more about your data and what you are trying to accomplish. Your current sql will select all columns from both the uploads and documents tables but only rows where the user id in both tables match, AND the user id equals 1. Is that not what you are seeing? Where's the code that outputs the results?

Get data from two databases?

Hello all,
Do anyone know if it's posible to get data from two databases while I'm running SBO in one of them? I need this because our client wants to be able to print reports with all the information stored in both companies. I searched this forum trying to find if this is possible but I did't find any information about this.
Can someone help me?
Thanks and regards,
Mariana Mazzero

Hi Mariana,
What you can do is use two company objects to retrieve the data. As far as I know you're not restricted to one company connection.
You can also just use a standard read only connection (like ADO/ODBC) to retrieve the data for the reports.
Hope it helps,
Adele

Select data from another database

Hi,
Is it possible to retrieve data from a table from another database?
For instance, I have two databases db_1 and db_2
I login to the database db_1 using
sqlplus username/psw@db1
and to the database db_2 using
sqlplus username/psw@db2
In SQL> db1 I would like to use select statement from a table in the db2. Is it possible?
Another question:
I have two tablespaces TP1 and TP2 in the database db1
The TP1 is my default tablespace.
Can I switch from TP1 to TP2 tablespace in the sqlplus?
If not, how can I select all tables obtained in the TP2? Or how can I select data from a table in the TP2?
Thanks

I don't know how to create a db link. 
SQL Reference Guide - CREATE DATABASE LINK 
There are some examples in the doc above. 
 
What about if db1 and db2 have the same table name? No problem, exactly like when you have two same table name accross two schemas on same database. The table suffixed by the dblink name come from the other schema of other database (schema which you use to connect through the dblink to the other database).

Fetch Data from two Database

I want to fetch data from two tables which are in two separate database. Is it possible to fetch similar from two schemas of same database.
Pls help with query.

Hi,
Say you have two schema S1 and S2 in the same database 'xyz' then you can create two database links to these two schemas from any third schema as ::
CREATE database link s1link connect to S1 identified by <password of S1> using 'xyz' ;
CREATE database link s2link connect to S2 identified by <password of S2> using 'xyz' ;
Now say if there is a table called tab1 in schema S1, then you can get data from it as ::
SELECT T1.*
FROM tab1@s1link T1
WHERE < you can put conditions here> ;
Similarly for the columns of a table of schema S2.

Selecting data from two different tables.

Do we need to use join two tables with primary/foreign key while trying to use select statement for getting data from those to table.? If no who can i go about do it.

If i am using From clause to get data from two different tables, is it necessary that both tables have column of identical data in them.In general, they ought to (or you need to join in a third table that tells you how to map rows from one table to rows of the other table).
It is not strictly necessary that there be any join condition between tables. If you don't provide a join condition, Oracle has to do a Cartesian product. That means that if there are n rows in one table and m rows in the other, the result set will have n * m rows. It is very rarely a good idea to write queries that do Cartesian products but it does occasionally happen.

What is best method to retrieve data from two databases

I'm writing a report that needs data from two sql databases. Not the same brand. Grouping and sorting fields come from both databases, so I can't just read one and retrieve data from the other. It seems to me I have to extract data from each data base using crystal reports, merge the two files using crystal reports and feed the merged file into crystal reports. I've not found a simpler or better method in the Crystal Reports documentation. Is there documentation about doing this process on the web site or with crystal reports documentation? My method seems cumbersome so I'm wondering if there is a better method.

Jeffrey,
A cheap and effective solution, for a periodic transfer would be using XML.
If you have the DDL for all of the objects in the database, you can just duplicate it on whatever RDBMS engine you want, and then, extract the data, table per table into XML files from the target server, and then load the files into the target server.
Otherwise, if you are going to do this in an ongoing basis, then, use SAP Replication Server. The best asynchronous, real time, heterogeous replication solution in the industry, exploited with a great deal of success by many critical mission financial applications with global topologies and sub second latency.
My two cents.
I hope they help.

Jean-Pierre

How do you Select data from two tables with similar data amd merge the output together.

I have two Tables containing Sales Data. I want to read the Table a sort by date and accumulate dollars by order date. Then I want to read the second table and accumulate these dollar amounts by date and then merge the records together so that I gave 1 row

Select data from database tables with high performance

hi all,
how to select data from different database tables with high performance.
im using for all entries instead of inner joins, even though burden on data base tables is going very high ( 90 % in se30)
hw to increase the performance.
kindly, reply.
thnks

Also Check you are not using open sql much like distict order by group by , use abap techniques on internal table to acive the same.
also Dont use select endselect.
if possible use up to n rows claus....
taht will limit the data base hits.
also dont run select in siode any loops.
i guess these are some of the trics oyu can use to avoid frequent DATA BASE HITS AND ABVOID THE DATA BASE LAOD.

Select data from table where field is initial

I have table that has 10 million records.
I want to select data from this table where certain date field is blank.
*SELECT * FROM table*
INTO TABLE internal table
WHERE PSTNG_DATE = BLANK.
Does anybody know how to select data from data base table when certain field is blank.
I cont select all data once and delete which i dont want, the table is big, it will blow up app server.
thanks in advance,
Sachin

Respect the forum rules and common sense, and you will be respected.
"how to select data from a database table when the field is blank" is very basic, and basic questions will be locked, because they have been asked many times and you can find the answer yourself with a little effort. There is nothing disrespectful about it.

Creating BAM report using data of two database tables. Say "EmployeeTable" and "DepartmentTable

I want to populate data from two database tables into a BAM report. I have created two data objects for the tables and want to create 3rd data object so that it can take the data from the other data objects automatically. Is there any such facility within BAM?

Hi
1. I am not sure if you have option to combine multiple DataObjects like that.
2. For your scenario, on Database side itself, I would recommend Create a VIEW that joins these 2 Tables and pull the required Columns and add required conditions. Verify the VIEW has all the rows expected.
3. Then create DataObject for this View. Once you have DataObject, create the Report.
Thanks

APEX Application accessing data from two different databases

Hi All,
Currently as we all know that APEX Application resides in database and is connected to the schema of that database.
I want APEX Application to be running and accessing data from two different databases. Elaborating my question,
Currently, my APEX Production Application is connected with XXXX Schema of DB1 Database(Where APEX Resides). Now I want to add some pages into this APEX Application for REPORT Purpose, But I want to connect this REPORT APEX Pages to get data from Different Schema YYYY for Database DB2.
Is it possible to configure this scenario?
The reason for doing this is to avoid the REPORT related (adhoc queries) resource utilization effect on Production DB1 Database.
Thanks
Nil

1. If you do the joining of two or more tables in DB1 then all data is pulled over to DB1 and then the join is executed: so more data over the databaselink and more work for DB1. Better keep the joining stuff where the data resides and just pull exactly that data over that you need.
2. Don't know about your different block sizes. Seems a nice question for one of the other forums (DBA or SQL).
3. I mean create synonyms on DB1 for reports VIEWS in DB2.
Hope all is clear!
