Tables and Joins used in constructing SQL

I am new to OBIEE. I contructed my physical layer table joins etc.
In my logical layer I have a source that is using a few physical tables. I have defined the joins (some right outer etc.). I go into Answers to display some info. When I examine my SQL source in NQQuery.log I see tables being used that I have not defined in my source. It is picking some from my other Logical tables. Why is that? Is it from the way I joined things in the Business Model?

Double post:
Outer Joins with multiple columns
The two post are similar. You have first to understand the logic of OBIEE.
And first which table is your fact table ?

List of SQL tables and attributes used in SSRS reports

Hi,
I have around 450-500 reports deployed in SSRS reporting server.
All these reports are built on SQL from multiple databases, and these databases are having unnecessary tables and attributes.
My requirement is to clean the unused tables and attributes from the databases. For this, I need the list of SQL tables and attributes used in these 450-500 SSRS reports.
Is there any way to get this data?
Regards,
RK

Hi RK,
According to your description, you want to get a list of the tables and attributes used in all reports.
In your scenario, you can query the ReportServer.dbo.Catalog table to get Report name, data source name, dataset name, and query used in the dataset with query below:
WITH XMLNAMESPACES ( DEFAULT 'http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition', 'http://schemas.microsoft.com/SQLServer/reporting/reportdesigner' AS rd )
SELECT ReportName = name
,DataSetName = x.value('(@Name)[1]', 'VARCHAR(250)')
,DataSourceName = x.value('(Query/DataSourceName)[1]','VARCHAR(250)')
,CommandText = x.value('(Query/CommandText)[1]','VARCHAR(250)')
,Fields = df.value('(@Name)[1]','VARCHAR(250)')
,DataField = df.value('(DataField)[1]','VARCHAR(250)')
,DataType = df.value('(rd:TypeName)[1]','VARCHAR(250)')
--,ConnectionString = x.value('(ConnectionProperties/ConnectString)[1]','VARCHAR(250)')
FROM ( SELECT C.Name,CONVERT(XML,CONVERT(VARBINARY(MAX),C.Content)) AS reportXML
FROM ReportServer.dbo.Catalog C
WHERE C.Content is not null
AND C.Type = 2
) a
CROSS APPLY reportXML.nodes('/Report/DataSets/DataSet') r ( x )
CROSS APPLY x.nodes('Fields/Field') f(df)
ORDER BY name

Sql query parsing (retrieve tables and columns used in query)

Hi,
1. Is there any view in Oracle which can tell me, which tables and columns were used in the last ran query, no matter how complex the query is.
2. Secondly I can get table names, used in stored procedures and views, using USER_DEPENDENCIES VIEW, however this System View does not return column names, used in that procedure / view, any idea please .
Thanks and Regards,
Luqman

2. Secondly I can get table names, used in stored procedures and views, using USER_DEPENDENCIES VIEW, however this System View does not return column names, used in that procedure / view, any idea please .Oracle added fine grained dependency tracking in 11g, but didn't expose any views to query this information. However, it has been reverse engineered a bit: About Oracle: DBA_DEPENDENCY_COLUMNS

Dimension build using SQL table and process to fill the SQL table

I have a dimension in a cube that is manually* built by one of our power users. Now I have to get all the member information of that dimension into a SQL table(example : with columns...level0,level0property,level1,level1property etc....) to use that table in STUDIO for member load.
Is there any easy process to do this? Currently I am building each and every row manually in that SQL table and there are 1100+ members in that manually built dimension. Please advice.

Thank you so much Glenn!! That worked!! You make our lives so much easier!!

Tables and Columns used in Universe (BO 6.5)

Hi All,
Please help me out with the below queries:
1. Is there any automated way to find out which report is using which universe? (may be through a SQL fired in BO repository)
(Note: As per the BO Documentation, OBJ_X_DOCUMENTS This is the only table in the document domain. It stores the binary content of all documents sent to the repository (through the user actions Publish to corporate documents, Send to users or Send to Broadcast Agent). The document contents are stored as BLOBs (Binary Large Objects) stored in slices.)
2. I need to identify the universes which use certain tables and columns.
I fired the following SQL in BO repository:
SELECT
UNV_UNIVERSE.UNI_FILENAME,
UNV_UNIVERSE.UNI_LONGNAME,
UNV_TABLE.TAB_NAME,
UNV_COLUMNS.COLUMN_NAME
FROM UNV_UNIVERSE, UNV_TABLE,UNV_COLUMNS
WHERE
UNV_UNIVERSE.UNIVERSE_ID = UNV_TABLE.UNIVERSE_ID
AND UNV_TABLE.TABLE_ID = UNV_COLUMNS.TABLE_ID
But as 'UNV_COLUMNS' table is empty, no data is returned. My question is is this table supposed to be empty in BO repository?
Is there any other way to find out this (identify the universes which use certain tables and columns)?
Many Thanks & Regards,
Sandeep

Hi,
Please find the below list of tables created in the BO repository, which helps you to retrieve the information related to reports, universes, users e.t.c.

Inserting in multiple tables and joining data

I am using DW8, PHP and MySQL.
I've created a database for software inventory. One table is
a list of software products and the other is the licensing
information. I set it up this way because we have a product such as
Windows XP that will have different licenses. But the end result
will be someone clicking on Windows XP and seeing all licenses for
that product.
I've created a page to insert into the software table and one
for the licensing information. Now I need to make a third page so
that the user can select the product from a dropdown menu and then
enter the licensing information. I have join setup between the
tables in the MySQL backend. How do I tell Dreamweaver that the
license being entered is related to the correct product?
Thanks!

Nevermind, I figured out how to do this.

Expand the Warehouse tables X adding physical tables and joins

I was questioned about these options:
a) Add physical tables (from other DBs) and modifying the physical model with new joins + modifying logical model to include new columns
b) Expand warehouse tables to include new columns in the tables. Doing a complementar ETL in order to feed the additional columns with data. Logical model would be updated but the idea in this option is to avoid joins in the physical layer.
My understanding is that option a) despite the joins in the physical layer would be a better strategy.
Pls. I'd appreciate any comments on the performance side or in the amount of effort to create the complementar ETL...
Txs.
Antonio

Hi Lombo,
I am not sure about what you mean with option a. In my understanding, you are asking for a comparison between:
a) adding data from an additional source in the RPD:
This means that you have to create an additional data source in the physical layer. I do not think you can create relations between physical tables sourced from different data sources in your physical layer. This means that the data is related in the logical layer. By doing this, the BI Server has to join the data from both sources for each front-end request. Also, it will have to perform the last aggregations instead of shipping it to the database. This is a big performance hit in terms of response time.
However! It can be much and much faster in terms of development effort required to support this. If it's only a limited number of columns and tables being added, this may be a valid option. You can also use this approach to prototype option b.
b) adding data from an additional source using ETL:
Quite some work in terms of development effort. However, all complexity and performance hits are moved to the bottom of the stack and process: database and ETL. You will need to create an additional data source in the DAC, additional custom folder(s) in Informatica and the ETL logic to update the existing tables and/or load new tables.
Additionaly, you need to expand the RPD with the new columns / tables, just as you would do in option a. However, now it will be sourced from the same datasource: less work for the BI Server to deliver the dataset to satisfy the request.
So basically, I would consider:
- How does the system currently perform: response times in the front end ( bad -> go for option b )
- How many columns will be added and how often will they be used in the front-end
- Informatica / DAC / OBI expertise available
- How long do you have to facilitate reporting on data from the 2nd source
Good luck!

How to search tables and views used in the code of oracle fmb 6i from another form???

Hii guys, this is a very interesting question and i hope that it will have ample amount of answers.
My requirement is to know the number of tables and views and backend functions/procedures which are used in the code written in the oracle forms 6i,
all i want is to display whole views, tables or functions/procedures which are written in the code of a particular fmb, i do have the path of that fmb and i want to read the code and search through it's entire code for the tables/views/backend procedures/functions written in the code. So how to search through the entire code of a particular form (6i) and make it display through another form.
I am using oracle forms 6i.

How to query 2 hierarchical tables and join?

Hi
I've been bashing my head against a well to get this to work efficiently in 10g. I can solve the following writing some pretty horrible SQL, but can't figure out how to do it elegantly and optimally.
We have two hierarchical tables as follows:
select * from data_categories dac
dac_code name parent_dac_code
10 MANAGEMENT
20 MEDICATION 10
30 PROCEDURE 10
40 SURVEY
50 ASSESS
60 NATURE 50
70 OBSERVE 60
select * from data_elements des
des_id name parent_des_id dac_code display_seq
100 DOSE MEDICATION 1
110 1MG 100 1
120 2MG 100 2
130 3MG 100 3
140 ROUTE MEDICATION 2
150 ET 140 1
160 EM 140 2
170 RESPONSE MEDICATION 3
180 IMPROVED 170 1
190 NOCHANGE 170 2
200 FILED MANAGEMENT 1
210 INPUT OBSERVE 1
You'll note:
1) We have hierarchies in both tables, and a fk from data_elements to data_categories via the dac_code.
2) The depth of both data_categories and data_elements is unlimited.
3) There is no single root node record in either table.
4) The appropriate PK and FK indexes exist.
We need to write a query that returns the following results:
root_dac_code parent_dac_code des_level des_id name display_seq
ASSESS OBSERVE 1 210 INPUT 1
MANAGEMENT MEDICATION 1 100 DOSE 1
MANAGEMENT MEDICATION 2 110 1MG 1
MANAGEMENT MEDICATION 2 120 2MG 2
MANAGEMENT MEDICATION 2 130 3MG 3
MANAGEMENT MEDICATION 1 140 ROUTE 1
MANAGEMENT MEDICATION 2 150 ET 1
MANAGEMENT MEDICATION 2 160 EM 2
MANAGEMENT MEDICATION 1 170 RESPONSE 3
MANAGEMENT MEDICATION 2 180 IMPROVED 1
MANAGEMENT MEDICATION 2 190 NOCHANGE 2
MANAGEMENT MANAGEMENT 1 200 FILED 1
You'll also note we need to return the data in order of the root_dac_code, then parent_dac_code, followed by the display_seq.
Does anybody know how to write this query in an elegant and optimal manner?
Many thanks for any help!
Cheers,
CM.

Flakey model.
Why does data_elements.dac_code appear to refer to data_categories.name rather than data_categories.dac_code?
You do not appear to be ordering by root_dac_code, parent_dac_code and display_seq (if you were MANAGEMENT/MANAGEMENT would not be at the end). Did you perhaps mean ORDER BY root_dac_code, des_id, display_seq?
Something like this perhaps?

Use SQL to INSERT a record into an Access table and populate using variables

I am having difficulties with the following code:
'Get my username
UserNameWindows = GetUserName
'Assemble my name and request corrections
MsgBoxTitle = "What name do you want to use?"
NewDefault = Replace(UserNameWindows, ".", " ")
NewDefault = StrConv(NewDefault, vbProperCase)
MyValue = InputBox(Message, MsgBoxTitle, NewDefault)
RealName = MyValue
'Assemble your email address
MsgBoxTitle = "What is your email address?"
NewDefault = UserNameWindows & "@calibreglobal.com.au"
MyValue = InputBox(Message, MsgBoxTitle, NewDefault)
EmailAddress = MyValue
MsgBox "Your UserNameWindows value is " & UserNameWindows & "."
'Insert UserNameWindows into the tblAuthorisedPeople table
strSQL = "INSERT INTO tblAuthorisedPeople (Person, RealName, EmailAddress) VALUES (" & UserNameWindows & ",""" & RealName & """, """ & EmailAddress & """)"
DoCmd.RunSQL (strSQL)
It asks me to enter the value for the Person field into a dialogue box instead of using the value of UserNameWindows.
After entry, it accepts the other values and enters the record correctly.
I have also tried this SQL string without success
strSQL = "INSERT INTO tblAuthorisedPeople (Person, RealName, EmailAddress) VALUES (" & Forms!frmCreateNew!UserNameWindows & ",""" & RealName & """, """ & EmailAddress & """)"
Any comments?
Barry Cuthbertson

Found the error. I had used the rules for the syntax from a web forum reply which appears to have been incorrect!
strSQL = "INSERT INTO tblAuthorisedPeople (Person, RealName, EmailAddress) VALUES (""" & UserNameWindows & """,""" & RealName & """, """ & EmailAddress &
This seems to be working well as the moment
All finished.

Now i want to create trigger when new record get inserted in employee table wanted to update person_id in employee_resources table.
So i want to match ems_candidate.name with employee.full_name , ems_candidate.ems_job_id with employee.ems_job_id. And if it matched then update person_id in employee_resources table else through an exception and insert record in temp table.
If anybody has an idea can u please help me.
Thanks,
Gayatri.

I created below trigger
CREATE TRIGGER emp_resources_upd_person_id
AFTER INSERT ON ems.employee
FOR EACH ROW
BEGIN
    UPDATE ems.employee_resources
       SET person_id = :new.person_id
     WHERE candidate_id = (SELECT ems_candidate_id
                             FROM ems.ems_candidate cand, ems.employee emp
                            WHERE TRIM(UPPER(emp.first_name)) = TRIM(UPPER(SUBSTR (cand.name, 1, INSTR (cand.name, ' ') - 1)))
                              AND TRIM(UPPER(emp.last_name)) = TRIM(UPPER(SUBSTR (cand.name,INSTR (cand.name, ' ') + 1,DECODE (INSTR (SUBSTR (cand.name, INSTR (cand.name, ' ') + 1), ' '),0,LENGTH (cand.name),(INSTR (SUBSTR (cand.name, INSTR (cand.name, ' ') + 1), ' ') - 1)))))
                              AND emp.person_id = :new.person_id);
EXCEPTION
WHEN OTHERS THEN
    INSERT INTO ems.update_person_id_exception(person_id,first_name,last_name,full_name) VALUES(:new.person_id,:new.first_name,:new.last_name,:new.full_name);
END;
Now when i am trying to insert row in ems.employee table it gives me an error
ORA-04091
table string.string is mutating, trigger/function may not see it
Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.

Can anybody please help me to come out from these error.

Kindly let me know if you need further info.

Issue identified. The datatypes of the stream order id and the one from the tables differ.
The Long could not be casted to the bigint format of CQL.
On changing the datatype of ORDER_ID in the CorpInterfaceEvent to int, the join is successful.

How to find Tables and Fields from R3 that some InfoSource use

Hi people,
I already know how to get the table or fields from R3 that some InfoSource use by "Portal SAP" that our friend here answered.
Now, I would like to know if there is some way to get this but using some transaction in the ECC6 (R3) or BW.
I ask by that because I will be some situation that I will have to know tables and fields that some InfoSource use and maybe there isn't in the Portal SAP.
Obs.: I don't know ABAP, so I would like some way that doesn't use Debug (ABAP), if it is possible.
Thank you,
Rosana.

Hi Rosanna
In many cases you will be able to get documentation from help.sap.com regarding the tables and fields used by standard datasources. For example for all the Sales and Distribution datasources you can refer the below link
http://help.sap.com/saphelp_nw70/helpdata/en/17/cd5e407aa4c44ce10000000a1550b0/frameset.htm
Here you can click on the different datasources and see both the table and field names. If you are looking for any specific datasource let me know...may be i can help.
Thanks.

Drag-n-n-drop query joins uses WHERE, not INNER JOIN syntax

When I highlight a few tables and drag them onto the sql worksheet, it will build a select statement for me and join the tables by their foreign keys.
That's a nice feature, thanks!
Three questions. Is it possible to:
1. get it to use the INNER JOIN and LEFT OUTER JOIN syntax instead of joining the tables in the WHERE clause?
2. control the table aliases so that it will automatically use the "standard alias" for the table instead of A, B, C, etc.?
3. get it to not put the schema name into the query?
Thanks!
Edited by: David Wendelken on Nov 22, 2008 1:48 PM. Grammar mistake.

Hi Gopi,
Your code is Good.
But try to avoid Inner join with more number of Tables ...because this is a performance issue..
try to use..
select (primary key fields mainly,other fields) from LIKP into itab where bolnr in p_bolnr(paramater).
next try to use for all entries option..
select (primary key fields mainly,other fields) from VBFA for all entries in itab where (give the condition)....
simillarly do for the other select ....ok this will try to reduce the performance issue....
