Unload dynamic data using JDBC into a file

Hi,
I have to download the result of a dynamic SELECT query into a file.
The query will be provided at runtime. So I am unsure of the number of columns and the data types of the columns.
Also I am unable to use io on the returned resultset object.
So basically i have to persist the data from the resultset object into a file.
Any hints
Thanks in advance

Also I am unable to use io on the returned resultset object.What do you mean by this?
See the JDBC tutorial: http://java.sun.com/docs/books/tutorial/jdbc/index.html
and the file I/O tutorial: http://java.sun.com/docs/books/tutorial/essential/io/index.html

DISPLAY SPATIAL DATA USING JDBC ON A JAVA FRAME

I am trying to set up some spatial data and need help in getting some sample
code for displaying the data on a Java Frame using JDBC.
The shapes I am setting up are simple polygons, lines, circles. I was going
through the samples in the demo directory under $ORACLE_HOME/md/demo/examples, but could not find any JDBC
I would really appreciate if you can point me towards some sample code and any other spatial resources.

Here you go. It uses JDBC to fetch geoms, convert them into Java JGeometry objects, which then create Java2D shapes (these are functions of the public sdoapi.jar library). It then uses some class in the sdovis.jar library (the rendering engine of MapViewer) to setup the necessary viewport transform. If you know how to setup the viewport transform, then you dont even need sdovis. sdovis.jar is found in an deployed MapViewer's WEB-INF/lib directory. Or you can extract it from the mapviewer.ear's web.war file.

How can I import data using .dmp into the table which has more columns then in import

I am building the history for warehouse purpose on Oracle 8i database and want to use the old import (.dmp) files (from oracle 7.3.4) to import data but the underlying table is having few more columns which are not in my old DMP file .. how can I import the data into these altered tables while using the same *.imp files .
Any solutions ?

That is the most obvious solution .. but think of the case when my operational database which is the source of my data is undergoing changes every quarter i.e after every 3 months there are some changes on underlying table structures which means structures of my import files will always be different after evry quarter .. you can imagine the number of temporary import structures I need to create .. can't there be a solution wherein I can write an SQL over the import file to read the data in required format ..

Writing CLOB data using UTL_FILE to several files by settingmaxrows in loop

Hey Gurus,
I have a procedure that creates a CLOB document (in the form of a table in oracle 9i). I need to now write this large CLOB data (with some 270,000 rows) into several files, setting the row max at 1000. So essentially ther would be some sort of loop construct and substr process that creates a file after looping through 1000 rows and then continues the count and creates a another file until all 270 xml files are created. Simple enough right...lol? Well I've tried doing this and haven't gotten anywhere. My pl/sql coding skills are too elementary I am guessing. I've only been doing this for about three months and could use the assistance of a more experienced person here.
Here are the particulars...
CLOB doc is a table in my Oracle 9i application named "XML_CLOB"
Directory name to write output to "DIR_PATH"
DIRECTORY PATH is "\app\cdg\cov"
Regards,
Chris

the xmldata itself in the CLOB would look like this for one row.

How to get sql query data and write into csv file?

I am writing to seek help, in how can I create bat. script which can execute the following logic:
connection to the database
run sql query
create CSV file
output query data, into CSV file
save the CSV file
osql
-S 84.18.111.111
-U adw
-P rem
-i "c:\query.sql"
send ""
sed -e 's/,\s\+/,/g' MCI_04Dec2014.csv > localNoSpaces.csv
-o "c:\MCI_04Dec2014.csv"
This what i have so far, and I am little struggling with the logic after creating CSV file. I am unable to get the above script to work, please advice further, where I may be going wrong.
Can you create if statement logic within window's script, to check for null parameters or data feeds?
Any hints would be most appreciated.

Thank you for your reply.
Apology for posting the code irrelevant to the forum, as I am still novice scripting user.
My goal is to create window's script which can compute the above logic and send the final output file (csv), to FTP folder.
Can this logic be implemented via bat. script, if so, is there a example or tutorial i could follow, in order to achieve my task.
Any help would be much appreciated.

Retrive Japanese data and store into a file

Hi,
I have a table which contains japanese data. My database charset is AL32UTF8. I am able to insert japanse data into oracle table also I am able to view inserted data into oracle table using sql*plus.
I wrote a java program to write a file with table stored data. To fetch that data I am using sql query. When I use ojdbc14.jar of version 9.0.2.0.0. Then I am able to write japanse data file but when I use ojdbc14.jar of version 10.2.0.3.0. Then I found junked data into data file.
Please help me out to solve this problem.

Initialize a date using eCATT and a file

We are trying to clear the values in a date field (MBEW-ZKDAT), i.e. we're trying to update the field from some date to the initial value.
We have an eCATT that has been working fine when there is some value in the date field. But when we try to put any other value (00/00/0000, 00000000 or just leave it blank) in the file, we're getting 'Invalid date' error.
I've looked in FAQ, SAP Help, but can't find any useful information on this. Does anyone know what we need to enter in the date field to make it blank (=initialize)?
Thank you.

Not able to fetch updated data using jdbc and oracle 10g

Whenever i m updating the data and fetching the same record after updating i m not able to get the fresh/new updated data , old record is fetched every time, but when i checked in database the record gets updated successfully , even if i fire the query two times after 10 seconds using Thread.sleep even then problem persist.
Please help me out!!!!!!!!
Implementation has been stucked up!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :(

Well its okWhat is OK? Your stuff working now?
i m doing the same thing Apparently not.
please go thru the below code fragment:
code for Update :::
DataAccessBean1 partsHistoryDataAccessBean = new
DataAccessBean1(context);
partsHistoryDataAccessBean.setData(data);
partsHistoryDataAccessBean.update();
After Updating i m forwading it to the other servletForwarding what? Why do you need another servlet? Just do the query, put the new data into the response object, and return.
According to your assumption i should get the updated
data on the other screen but Nope, you don't understand what I'm saying.

This error message is displayed when the call is made to get the character stream from the Clob object.
Do I need to any server side setup before I can access CLOB data from the database?
thanks.

Assigning an exact time to poll data using JDBC Sender?

Hi,
Can I set an exact time to poll data from DB table?
I means, I want to poll data every 6 pm.
But I cannot find fields to set starting time.
There exist only poll interval fields in JDBC Sender.
Regards,
hiyoung.

Hi,
This might help you out.
To run a scenario exactly once in a specific time every day / schedule a adapter
Note:You will need to have the authorizations of the user group SAP_XI_ADMINISTRATOR with the role modify.
Go to Runtime Workbench -> Component Monitoring -> Communication Channel Monitoring
Locate the link Availability Time Planning on the top right corner of your Communication Channel Monitoring page.
In your case, the requirement is to schedule the Sender file adapter daily once at 12:00 at midnight.
In Availability Time Planning, choose the Availability time as daily and say create.
Provide the details like the time 12:00
Then select the communication channel , goto the Communication Channels tab and filter and add the respective channel (File Sender).
Once all the above has been done 'Save' the changes.

How do I insert the Date in time into my file?

Temperature_Testing_Modified.vi ‏71 KB

Give the operator a front panel control to enter the Save Interval. Use a shift register on your While loop (initialized to a Double = 0) to hold the Last Time Saved. In your loop, call the Get Date/Time in Seconds function (from the Time & Dialog palette). If the current time - Save Interval > Last Time Saved, save the data and update the Last Time Saved.
See the attached LabView 6.1 example.

Need a suggestion in getting data using JDBC

Hi,
There is a Emp table in database.
     And there is a corresponding Value Object(Contains getter and setter
     methods for columns of Emp table).
     If i fire a query to Emp, then the records will be stored in ResultSet.
     I am passing the table as a paremeter to a method.(so that no. of columns
     should vary)
     Now my problem is how can i initialize each column value getting from
     ResultSet into corresponding VO setter method.

Like this probably: vo.setX(rs.getInt("X"));

Need suggestion in getting data using JDBC

     please do the needful.

Hello inform2csr,
Your question is not so clear.
