Data to fetch from file

Dear All,
which parameter decides how data to fetch from file ?
Regards

I think either friend is asking you command (not parameter) to fetch the data from datafile; so it is SQL's Select command which will read the datafile as user process on the db server.

How the data is fetched from the cube for reporting - with and without BIA

hi all,
I need to understand the below scenario:(as to how the data is fetched from the cube for reporting)
I have a query, on a multiprovider connected to cubes say A and B. A is on BIA index, B is not. There are no aggregates created on both the cubes.
CASE 1: I have taken RSRT stats with BIA on, in aggregation layer it says
Basic InfoProvider     *****Table type      ***** Viewed at      ***** Records, Selected     *****Records, Transported
Cube A     ***** blank ***** 0.624305      ***** 8,087,502      ***** 2,011
Cube B     ***** E ***** 42.002653 ***** 1,669,126      ***** 6
Cube B     ***** F ***** 98.696442 ***** 2,426,006 ***** 6
CASE 2:I have taken the RSRT stats, disabling the BIA index, in aggregation layer it says:
Basic InfoProvider     *****Table Type     *****Viewed at     *****Records, Selected     *****Records, Transported
Cube B     *****E     *****46.620825     ****1,669,126****     6
Cube B     *****F     ****106.148337****     2,426,030*****     6
Cube A     *****E     *****61.939073     *****3,794,113     *****3,499
Cube A     *****F     ****90.721171****     4,293,420     *****5,584
now my question is why is here a huge difference in the number of records transported for cube A when compared to case 1. The input criteria for both the cases are the same and the result output is matching. There is no change in the number of records selected for cube A in both cases.It is 8,087,502 in both cases.
Can someone pls clarify on this difference in records being selected.

Hi,
yes, Vitaliy could be guess right. Please check if FEMS compression is enabled (note 1308274).
What you can do to get more details about the selection is to activate the execurtion plan SQL/BWA queries in data manager. You can also activate the trace functions for BWA in RSRT. So you need to know how both queries select its data.

Jens

Hi Jay,
Thanks for sharing your analysis.
The only reason I could think logically is BWA is having information in both E and F tables in one place and hence after selecting the records, it is able to aggregate and transport the reords to OLAP.
In the second case, since E and F tables are separate, aggregation might be happening at OLAP and hence you see more number of records.
Our Experts in BWA forum might be able to answer in a better way, if you post this question over there.
Thanks,
Krishnan

Can data be fetched from Oracle Database to ApEx websheets?

Hi,
Oracle 11g R2
ApEx 4.2.2
We are in need of giving an MRU form for the customized data by the users. The number of columns will be defined dynamically by the end user. We thought of using apex's standard tabular forms, but they cannot have dynamic columns. We also thought of having manual tabular forms using apex collections, but there is a limitation that the collection can have maximum of 50 character datatypes, 5 numeric, 5 date and 1 each for clob and blob. The number of columns at runtime may exceed these numbers. so we ruled out this. We then thought of using apex websheets. We know that the data can be fetched from Oracle database to websheet reports, but the reports cannot be edited. We know that the data grid gives option to edit the data, but I couldnt find a way to fetch the data from database to it. I understand that the data in the apex websheets can be queried from apex's meta tables apex$_ws_... views and somehow in a back door way of doing these can be updated to the business tables. But we also need to fetch the data from Oracle database to the grid. I do not want to insert into the apex$_ws tables as Oracle does not support it. Is there any other possibility?
Thanks in advance.

Natarajan

Thanks for your reply. Actually it is a data that is fully customized by the end user. These custom attributes are really stored as rows and a complex code returns them as columns at run time. So the number of columns is different user to user based on the number of rows they have.
They'd never have got that far if I'd been around...
They now want to edit them in a tabular form as well.
Well once you've implemented one really bad idea, one more isn't going to make much difference.
It rather sounds like you've got people who know nothing about relational databases or user interfaces responsible for the design of both. You need to be very, very, worried.

How to Read specific data from file and do a calculation and display on the output

FYI: Below is the function use for the writing:
-OpenFile(use ASCII)
-sprintf
-WriteFile
Example: Output from the doc file
…EndTime: 09:34:48 program time: 0.567663 sec
…EndTime: 09:36:48 program time: 0.666666 sec
My objective is to read data 0.666666 (FYI: is last sentence of the file) to do some calculation. How can we read specific data(specific location) from file..
Any advice or help?
What is the function needed?

I would consider counting line feeds and checking for end-of file to isolate the last line, which then can be read using fscanf...
Have a look at getc...
character = fgetc ( stream );
if ( character == '\n' ) // new line
if ( character == EOF ) // end-of-file

Pick value from file in FOR loop

Hello All,
I was trying to delete records from database day by day and commit. Is it possible to pick the dates from file and then delete the database record for that day. Something like below.
For day IN <File.txt>
LOOP
delete from table where date = '<1st value from File.txt>';
commit;
END LOOP;
I have to do this from unix box, so i can place the file (with list of dates as input) in the path from where i am issuing sqlplus.
Please suggest any other way to delete it day by day is most welcome.
Thanks.

Something like below.You an use EXTERNAL TABLE (Or SQL Loader, if the file cannot be moved to the DB server) to read from a file and it can be used in your DELETE statements just as a normal table.
>

LOOP
delete from table where date = '<1st value from File.txt>';
commit;
END LOOP;
LOOP is a bad idea.. You could do it in a single statement..
delete from table where date in (select the_date_coumn from the external_table);
And COMMIT inside LOOP is again not a good idea..

How to ensure that the query results are fetched from the BW acclerator.

Hi Experts,
Suppose if i want to execute the query with BIA option, I can achieve it in RSRT .
1)But is there some query settings or properties where we can make sure that whenever a query(say Q1) is executed, always the data should be fetched from the BIA index.
2)Suppose the BIA indexing has failed due to some reasons, will the data be fetched from the previously updated BIA index??
regards
akshay

Hi man,
1)But is there some query settings or properties where we can make sure that whenever a query(say Q1) is executed, always the data should be fetched from the BIA index.
If you have built up BIA index on a cube, then every query on the cube or MultiProvider will automatically use BIA index. No additional settings required. You can use the following way to test whether a query is using BIA or not:
Go to RSRT, input query name, click 'execute and debug' and check 'Display Statistics Data' and 'Do Not Use Cache'. Execute. After the query result press F3, now you should be able to see statistics. There's a tab 'BIA Access'. If you see something there then it means BIA index is used.
2)Suppose the BIA indexing has failed due to some reasons, will the data be fetched from the previously updated BIA index??
If BIA rollup is failed, then the last request(s) would not available in reporting and query will use BIA index for earlier requests. You can consider it like aggregate. But if initial fill of BIA failed then you would not be able to use BIA index.

Frank

Read table data and fetch file from path specified in table column

Hi,
I have a situation where file path information is stored in database table along with other columns - I need to read data from SQL Server table row by row, go to the path identified by the record, check for existance of the file - if the file is available copy it to a staging area, then read the next record. Repeat this process until the last record is fetched from the table. At the end, zip all the files found and FTP to a different location. If the file is not found in the path specified, write the database record to a seperate text file.
At end of the process, send an email with records for which files were not found at specified location.
Thanks

Hi,
That is not complex to solve at ODI.
Try the following.
1) Create a package
2) create a variable to receive the path as parameter and drag and drop it at package as "Declared"
3) drag and drop the ODI Tool "odiFileMove" using and let the variable as patch at ODI Tool parameter.
Use the parameters -ACTION=MOVE -TIMEOUT=100 and -NOFILE_ERROR=NO (take a look at ODI Toos Reference for other parameters)
3) Create a "KO" (error) flow to write the variable at a text file. That will allow the process knows what file is missing
4) generate a scenario of this package
5) create a procedure
6) at first step, put the query from SQL Server (set the Logical Schema to the right connection)
7) at Target tab, put the call to the scenario generated using the returned value from query parameter. Plus, let the -SYNC_MODE=1. That will call one scenario by time.
8) create a new step to zip the files at stage directory
9) create a step to make the ftp
10) create a step to mail the txt generated with files not founded. If you wish, you can make a validation on the file to see if is necessary to send the mail, it means, if there is any file missing.
Does it help you?

Some music files do not show up in google play music app library. I did clear cache/data and restarted phone. The music is stored on the SD card. Most of the music in the library is in the same folder on the sd card. I can play the song from file mana

some music files do not show up in google play music app library. I did clear cache/data and restarted phone. The music is stored on the SD card. Most of the music in the library is in the same folder on the sd card. I can play the song from file manager, but it still is not in the music library in play music.

Cyndi6858, help is here! We'd be happy to help figure this out. Just to be sure though, the Droid Maxx should not have an SD card. Is this the Droid Razr Maxx? How did you add the music to the device? Are you able to see the files and folders located on the SD card or device when plugged in?

How to view data in Xcelsius from an external Excel file

Hi Everyone,
i wonder if you know How to view data in Xcelsius from external Excel file and not depend only on the emebded excel sheet.

Hi,
As per my understanding, excel has to be imported in Xcelsius to draw up the dashboard. Your aggregated data sits in the xlf file. Using an external excel file will not be possible (I guess).
One of the ways to connect to an external excel, is the use XML Maps but then your data has to be in the form of XML which will be pulled into excel first and then needs to be brought in Xcelsius using Data Manager.
You can explore XML Maps in xcelsius in SDN.
