EPM tables in relational database

Hi,
Can you please let me know when is the tables are actually created within the SCHEMA( Shared services or EAS ) in the relational database. Is it during the EPM configuration that the tables are created in the database automatically?
Appreciate your input and thanks for your time.
Thanks,
Hari

Yes the tables are automatically created and populated at the point of configuration.
Cheers

Insert XML file into Relational database model without using XMLTYPE tables

Dear all,
How can I store a known complex XML file into an existing relational database WITHOUT using xmltypes in the database ?
I read the article on DBMS_XMLSTORE. DBMS_XMLSTORE indeed partially bridges the gap between XML and RDBMS to a certain extent, namely for simply structured XML (canonical structure) and simple tables.
However, when the XML structure will become arbitrary and rapidly evolving, surely there must be a way to map XML to a relational model more flexibly.
We work in a java/Oracle10 environment that receives very large XML documents from an independent data management source. These files comply with an XML schema. That is all we know. Still, all these data must be inserted/updated daily in an existing relational model. Quite an assignment isn't it ?
The database does and will not contain XMLTYPES, only plain RDBMS tables.
Are you aware of a framework/product or tool to do what DBMS_XMLSTORE does but with any format of XML file ? If not, I am doomed.
Constraints : Input via XML files defined by third party
Storage : relational database model with hundreds of tables and thousands of existing queries that can not be touched. The model must not be altered.
Target : get this XML into the database on a daily basis via an automated process.
Cheers.
Luc.

Luc,
your Doomed !
If you would try something like DBMS_XMLSTORE, you probably would be into serious performance problems in your case, very fast, and it would be very difficult to manage.
If you would use a little bit of XMLType stuff, you would be able to shred the data into the relational model very fast and controlable. Take it from me, I am one of those old geezers like Mr. Tom Kyte way beyond 40 years (still joking). No seriously. I started out as a classical PL/SQL, Forms Guy that switched after two years to become a "DBA 1.0" and Mr Codd and Mr Date were for years my biggest hero's. I have the utmost respect for Mr. Tom Kyte for all his efforts for bringing the concepts manual into the development world. Just to name some off the names that influenced me. But you will have to work with UNSTRUCTURED data (as Mr Date would call it). 80% of the data out there exists off it. Stuff like XMLTABLE and XML VIEWs bridge the gap between that unstructured world and the relational world. It is very doable to drag and drop an XML file into the XMLDB database into a XMLtype table and or for instance via FTP. From that point on it is in the database. From there you could move into relational tables via XMLTABLE methods or XML Views.
You could see the described method as a filtering option so XML can be transformed into relational data. If you don't want any XML in your current database, then create an small Oracle database with XML DB installed (if doable 11.1.0.7 regarding the best performance --> all the new fast optimizer stuff etc). Use that database as a staging area that does all the XML shredding for you into relational components and ship the end result via database links and or materialized views or other probably known methodes into your relational database that isn't allowed to have XMLType.
This way you would keep your realtional Oracle database clean and have the Oracle XML DB staging database do all the filtering and shredding into relational components.
Throwing the XML DB option out off the window beforehand would be like replacing your Mercedes with a bicycle. With both you will be able to travel the distance from Paris to Rome, but it will take you a hell of lot longer.

Help creating a relational database table

Hi,
I need help creating a relational database data. I am suppose to enter the following information in the workstation:

I entered the information in the workstation but I have no idea what to do with this command-------->SELECT TABLE_NAME FROM USER_TABLES;
Pleaaaassssse help me.
Thanks in advance,

Thanks for responding so quickly. I'm sorry if I said
it wrong, this is completely new to me. This is what
I am suppose to do:
Directions:
1. Login to the DVOLUSER (select this from the
Connection Identifier drop down window) Oracle
instance using the username and password provided to
you.
2. Use the following SQL syntax to create the patient
table in the database:
CREATE TABLE patient (
MedRecNo number (4),

3. Query (using the syntax below) the database to
ensure that you have created the table:
SELECT TABLE_NAME FROM USER_TABLES;ETA: I also do not know how to enter this into the data base. I mean I enter the following information into the database and then I click execute but once I do that, what do I do with the SELECT TABLE_NAME FROM USER_TABLES;

How to create a view consisting of data from tables in2 different databases

Using Oracle 10.2g
I have 2 databases Gus and haggis on Comqdhb schema.
glink indicates a databse link between Haggis and Gus
In Gus there are tables student,subject,grade,school containing columns like upn...
STUDENT
upn
academicYear
SUBJECT
subject
GRADE
examlevel
grade
SCHOOL
sn
In HAGGIS there are tables student,grade,teacher containing columns upn...desc below.
STUDENT
upn
GRADE
grade
upn
academicyear
level
Create view in your HAGGIS database which will join all of the exam grades together. You should have one view which will produce the following relation :
examGrade(upn, subject, examlevel, sn, grade,academicYear)
so I need to create a view which gets the data from both the tables in both the databases.
create view as examGrade(upn, subject, examlevel, sn, grade,academicYear) as select s.upn
But i am not getting how to select a column from 2 tables in different databases
I mean if i said
select upn from comqdhb.student@glink,comqdhb.student;
select upn from comqdhb.student@glink,comqdhb.student
ERROR at line 1:
ORA-00918: column ambiguously defined
help me out,Thank you.

Thank you for the reply will follow up the code format
Create views in your HAGGIS schema database which will join all of the exam grades together. You should have one view which will produce the following relation :
examGrade(upn, subject, examlevel, sn, grade,academicYear)

Another problem i am having which i am trying to solve and written up my ideas but haven't been getting the expected results.Hope you can help.Thank you.
Information:
=======
All children take exams at the age of 16 called a General Certificate of SecondaryEducation (GCSE).
They have to study and take exams in Mathematics, English and Science, and can take other subjects such as History, French, Art etc. Most students will study between 5 and 10 different subjects before taking their GCSEs.
For each exam, a student is awarded a grade from A*, A, B,C,D,E,F,G,U,X An A* grade is the best grade achievable and an X is the worst grade.
In order to analyze how students have performed, each grade is mapped to a numeric value as follows:
Grade Numerical score
A* 8
A 7
B 6
C 5
D 4
E 3
F 2
G 1
U 0
X 0
Now why i need this avgGCSE is because i have to create a view containing avgGCSE of the students it is used in the next question where a condition is avgGCSE is between 6.5 and 7
In order to calculate the avgGCSE the idea is to calculate the grades of the students and map the grades to their corresponding scores/values
add them all up and div by the total no of grades to get the avg.
desc comqdhb.STUDENT@glink;
STUDENT

I have a opinion that xgcse in STUDENT table refers to the avgGCSE which i want to calculate as when i asked my professor as to what xgcse he said that he forgot to take it out of the table and it is not necessary while creating avggcse.
select *
from comqdhb.student@glink
where xgcse<6.5; Displaying a result
returns:

select *

where xgcse between 6.5 and 7 and upn = 1386; Displaying a result
returns:

===========================================================================
1386 STEPHANIE AANNESSON 15-JAN-79 f none 6.88873 2 2 so if xgcse is the avgGCSE then upn 1011 has avggcse<6.5 and 1386 has avggcse >6.5
my idea was backward strategy like so now if we find out upn 1368 has suppose xgcse(avggcse)>6.5 how to extract the avggcse for the particular upn We need to map grades from GRADEVALUES to grade in STUDENTINGROUP and map upn from studentingroup to upn in student to output the values for the corresponding grades from GRADEVALUES
select grade
from comqdhb.studentingroup@glink
where upn = 1011;
Result:
GRADE
=====
D

C

8 rows selected. Mapping each grade to the corresponding value and calculating we get
32/8=4 total(values to corresponding grades)/no of grades.
But the xgcse for upn 1011 is 3.935 and i am getting 4!! maybe xgcse isn't avggrade but ? is the procedure by me correct for calculating avggcse
select grade
from comqdhb.studentingroup@glink
where upn = 1386;
Result:

Limitation on the number of tables in a Database Schema!

Hi All,
Is there a limitation on the number of tables present in a schema that can be fetched in Designer while creating a universe.
Customer is using Oracle schema which contains 22000 tables and while trying to insert tables in Designer XIR2 (or trying to get the table browser) Designer hangs.
In BO 6.5 there are no issues while retrieving the tables from the schema in Designer.
Is there a way to retrieve only a certain amount of tables in Designer XIR2?
Thanks for your help!

Hi Ganesh,
Following are the Answers regaring your queries:
Query : 1
There is no limitation on the number of components (objects, classes, tables, joins, hierarchies, lov's, etc) in a universe. But of course as the number of components increases, you could run into problems related to performance.
This depends on available RAM and the processing speed.
Query 2:
There is NO such option to select the number of table to be automatically inserted in to the universe because Suppose if you have 22000 tables in DB and you want only 1000 table ,you entered 1000 tables as the value to insert tables in Universe then How Designer will come to know which tables you want to take in Schema to build the Universe?
It all depends on the DBA and Universe Designer which tables are important for organizations reporting needs.
When you create connection to the DB then Connection will fetch all table from the database and we canu2019t limit DB data retrieval.
I hope this Helps...
Thanks...

Access table directly from database in BO 4.0 WebI Report without using Universe

Can i use the table avilable in database directly to make BO 4.0 WebI Report without create any universe.
I realy appeiciate your help.
Thank you in advance.

You need to create a universe for Relational SQL databases. Universe is a must. The reason you create universe is for the end users. WebI is designed for end users to create their own reports. It is a self service reporting tool. In order to do that, you need universe which allows users to query database using SQL without knowing SQL language.
If you don't want to create a universe for reporting then you can use Crystal Reports instead of WebI

I don't have the option to create a new table in my database

Hi, I have SQL 2014, for some reason, a few weeks ago I was able to create a new table for my databases, now, I don't have the option to do so, all I get when I right click on tables is "Tables..." instead of "New Table", when I select
"Tables..." it allows me to write my codes but it doesn't save except in a text files witch doesn't want to open when I want to resume my work.
Is there any option in SQL to activate the "New Table" by right clicking on Tables? I have all the rights and permissions available to my use as it's my computer and my own server.
To fix the issue I tried
-Re-installing SQL
-Changed for 4 different versions
-Allowing more than necessary permissions
-Making it public to use (it's only to test it, anyway, I'm in the learning phase)
Any kind of help or advice will be welcome and much appreciated.
Thank you!

I don't know the reason why you are experiencing this, so what I am describing below are just some steps that you can take to diagnose the problem if it is related to a permissions issue.
1. If you are not already on the computer where SQL Server is installed, login on that box and launch SQL Server Management Studio and run it as Administrator.
2. Connect to the Server and open up the object explorer and expand the Security node that is directly under the Sever tab.
3. Under logins, find your login, right-click properties and see what kind of server level permissions you have, and which databases you are mapped to and what kind of permissions you have on those.
It may just be that this is not related to permissions at all, but I can't think of what that would be. To test whether it is a SSMS GUI problem or not, open up a query window and select a database on which you think you have permissions to create tables.
Then create a test table using T-SQL, for example:
create table dbo.MyTestTable( col1 int);

Unable to copy table in same Database

I m using jdbc:odbc bridge to connect to MS access database. i am trying to create a table by copying data from another table in same database. the code is
Statement stmt = mycon.createStatement();
String query = "create table " + temp1 + " as select * from " + temp2;
stmt.executeUpdate(query);
But java is throwing exception as:
java.sql.SQLException: [Microsoft][ODBC Microsoft Acces Driver] Syntax error in
CREATE TABLE statement.
Simple create and select are working fine. Is there something like MS Access doesnt support such queries?
Thanx for help
Viney

Hi Viney_yadav,
First a general suggestion: The error message you got states that is a SQL syntax error. This tells you that you should try running the SQL that is failing directly through Access and correct the syntax problem there. That will help you verify the SQL syntax and avoid any complications related to Java.
And now some specific help (cut/paste from a previous life): Different DBMS's handle the SELECT INTO... differently. SELECT INTO... in Microsoft Access actually creates a new table. If the table already exists (in Access) then you would use the INSERT INTO..SELECT... statement.
EXAMPLE to create and populate a new table in Access (sorry didn't test this):
select temp2.* into temp1 from temp2

In which table invoices related to a purchase order are stored ?

Hi all,
We need to make an ABAP program and I need to know in which table the invoices made by MIRO related to a purchase order are stored.
I can see them in the purchase order history tab in the transaccion ME23N but giving F1 and getting the table names gives me a structure table but not the actual table in SAP database. I tried the BSEG table but it doesn't store the purchase order number. Any information will be highly appreciated.
Thanks !!

Hi
You can get the Link of PUrchase order & the Invoice from Table EKBE.
You can also get the data by joining the table RBKP & RSEG, as the Purcahse order details are stored in RSEG & posting date details are stored in RBKP
Thanks & Regards

How to store, in an effective way, analyzer data into a relational database?

We want to store the "sweep traces" of a network analyzer in a relational database in a way that it saves as much as possible space without loosing resolution.
The solutions were we thinking on are to separate the x-axes information from the y-axes information and store it in different tables of the database.
Because the repeating character of the measurements the data in the x-axes will be nearly all ways the same. So we want to store only new data in the x-axes table as a different x-axes is detected.
In a third table we want to save the relation between the x and y data and other data that belongs to the measurement.
Question is are there other or better possibilities to solve this proble
m?

Hi Ben,
Thanks for you help.
The use of a third table that links the X-axe and y-axe table together depends on if I store the datapoints in the y-axe table sequential, so I need an identification of the points belonging together and I can have a varying number of data-points, (i.e. 401 of 801 ...) or I save it in one record.
The problem here is I have to save a varying nummer of points in tables with a lot of "datapoint columns".
Another solution is save the datapoints as a semicolon ( separated text string in one field.
Problem now is the limitation in the max. text field length.
In my Oracle Rdb database I can use "Varchar" fields.
(is here no limitation??)
In other databases a "Note field" will maybe give a solution.
The question sti
ll is: What is the best solution and uses the smallest amount of space?
In the next week I will do some tests with the solutions mentioned.
Please let me know what DSC is??
Greetings Huub

How to search all columns of all tables in a database for a keyword?

Dear Team,
i have an requirement that : i want to search all the columns of all the tables in the particular database based on the specific key word or an free text.
example :
table 1: columns data
empname sam
empid 01
table 2 columns data
deptname sam
departmentid 10
table 3 columns data
organization name sam
organization id 1
when i search for text " SAM"
it should search me from the entire database, all tables and columns of it and display the result
output : tablename cloumn value
table1 empname sam
table2 deptname sam
table3 organizationame sam
the example is just an sample not the real data .
please help me with sample code or any link related to it .
thanks in advance

Hi justin , thanx for the reply
the basic requirement that we required is ,
the user will just type the keyword( value in the coumn) he required and it should search all the tables and columns of the table in the database and i have to show this in the front ent in the table format. here the user will analyse the information based on the search .
it is just like the google search we does( type the keyword in free text) it will display the result.
so for that i have to search entire table and columns in the whole database.
please if any one provides me the solution it will be help full for me.
thanx in advance

What is te best way to copy a table from a database to another?

Hello friends:
I have two databases: an Access database and an Oracle database. I must copy the data from al tables from the Access database to the oracle database. The tables in the both databases are equal (number of columns, type, etc).
I read an resultset from acces (select * from table1) and I insert every row in the Oracle database with an while loop (while (r.next)...). It works fine when there are a few rows, but I have a table with over 200000 rows, and when I'm copying the row number 30.000, the system goes very slow...
How can I copy tables from a database to another more quickly?
Thanks!

CASE #1
The most efficient method would be to copy all the rows from Microsoft Access and write them to a text file using Access's native interface (not JDBC), then use Oracle's SQL Loader utility (not JDBC) to insert the data.
You can insert 200,000 rows of 80 bytes each in 30 seconds or less even on a modest Oracle system using SQL Loader. The extract from Access is very dependent on the size of the CPU and the available memory.
Hint 1: Avoid explicit or implict network traffic.
Hint 2: Extract and load from local drives rather than networked or shared drives on other services
Please note that this is done for efficiency of load, but has issues related to error checking, and operational scripting.
Anything else you do or use will be slower than the method (above).
CASE #2
If you want to integrate this into a single JDBC program which will provide better operational management of the process, then you can simply connect to both databases in your Java program, then read the rows one at a time from Access, insert them using the Batch mechanism of JDBC to Oracle. You will also want to set the FetchSize in Oracle to a larger value then the default (i.e set it to 100 vs 10).
Hint #3 You may want to look into alternative JDBC drivers for accessing MS Access, rather than the JDBC-ODBC bridge which is not optimized for MS Access. You may also want to consider using the OCI8 driver from Oracle rather than the thin driver. Both provide Type 4 functionality but I have heard (not experienced) that the OCI8 driver is better for managing batch style of processing like yours
Good luck!
