How to retrive data from the database by using resultset metadata

Hi
I am very new to java programing.please help me anyone...
In my table 20 fields are there.I want to retrive those fields and put it into arraylist.and return the arraylist.
regards
guru

First get Column count by using      getColumnCount() method
Then Get The Column name by using getColumnName(int column)
By using column name You can retrieve values
eg:
String columeName=null;
int count = mymetadata.getColumnCount();
for(int i=1;i<=count;i++) {
columeName = getColumnName(i);
//Retrive values from resultset buy using columeName
}

  • How to retrieve data from the Database after deleting rows from VO ?

    Hello,
    I am using Jdeveloper 11.1.2.1.0
    I have a master and a child .
    So according my use case when a value in the master vo changes the corresponding child has to be deleted.
    but when i change back to any other value i want to undo the delete operation and get back the values in the child.
    Is there any way to do it?

    Hi all,
    I want to do a validation based on a SelectOneChoice List Value.
    Based on which value in the select one choice is being selected, thedata from the VO should be DELETED or NOT-DELETED.
    To do this I wrote a Managed Bean and the delete part is working fine if a particular value of the SelectOneChoice is selected.
    Since the rows are deleted from the VO, after I change the SelectOneChoice value to the previous one I cannot retrieve the rows.
    I thought of two ways:
    1. As the Deleting option in the SelectOneChoice is selected the rows should be deleted from the VO and when reverted back to not-Deleting option the Rollback of Transaction method written in the Managed Bean should take place.
    2. As the Deleting option is selected the data should be deleted from the VO and when reverted back to non-Deleting option, a query should be made from the Database.
    The first plan was dropped because it is not VO-specific. If there are more than 1 VO in the page then whatever changes are made in the page will be reverted back as soon ad Rollback of transaction is done.
    So the now i am left to go with the second plan.
    Is there any way to implement the second plan?
    If so...Will it compromise the performance of the application?
    Or else, Is there any other way to implement my Use-Case ???

  • How to get data from the called program using SUBMIT in a background job?

    Hi Experts,
    I've a program which creates a background job using JOB_OPEN and JOB_CLOSE function modules.
    Between the above function modules I need to call a program using SUBMIT VIA JOB statement.
    My problem is, How do I fetch some data in an internal table in the called program to the calling program after the SUBMIT statement?
    I tried to EXPORT and IMPORT the data, but they are giving a failed sy-subrc when using this background job.
    Kindly let me know your inputs and valuable suggestions.

    Kumar,
    When we execute a program as a background job then the output will be sent to Spool which needs to be fetched again.I guess we need to use Submit via spool as mentioned by Rajat.
    Check these threads to get some idea
    submit report to spool & import spool id

  • Failed to retrieve data from the database/invalid argument provided when employing link between two web services datasources

    Post Author: vpost
    CA Forum: Data Connectivity and SQL
    I am trying to join information from two related web services within CR XI. I have successfully set up the web services as data sources have been able to get to the point where I get good data back. However, when I try to pull in certain fields, I get an error that says "Failed to retrieve data from the database/invalid argument provided". Here's the scenario:
    The web services are structured as follows:Web Service 1 (Artist) has attributes of Artist Name and Date of Birth.Web Service 2 (CD) has attributes of CD Title and Release Date. Underneath each CD are songs, each of which have a Song Title and Artist Name.
    I have defined both web services and defined a link between Artist.Artist Name and CD/Song.Artist Name. I am able to run a report with Song Title and Date of Birth that crosses web services. I am able to run another report with Song Title and CD Title that crosses the different levels in the second web service. However, if I add CD Title to the first report or Date of Birth to the second (both of which effectively force CR to employ the link between the two web services AND the CD/Song hierarchical structure in the second web service, I get the aforementioned error.
    Any assistance understanding how multiple web services can be linked in this manner would be greatly appreciated.
    Thanks in advance.

    Not sure about your exact situation, but having similar problem with another application and have tracked down to security. Added user to group Domain Admin and it works fine. It appears to be accessing a subdirectory which it does not have permission to use and then times out and returns the "invalid....". Seems that once the query just over a certain size (and I'm not sure what triggers this) it needs to make use of temparory file disk, intead of ram.
    I'm still trying to track down which temporary it's trying to uses - so if you have any ques.

  • Crstal Reports: "Failed to retrieve data from the database"

    Running a report in crystal report from SAP 8.81 using the following parameters: CardCode, GroupCode, Date gives the following error: "Failed to retrieve data from the database" "Conversion failed when to converting the nvarchar value to data type int 12/31/2005 [Database vendor code: 245] ".
    The store procedure in SQL Server executes smoothly and  If you run the report with the date = 12/31/2005 in the parameter also returns expected results.

    Hello,
    Is this in Business One? If so CR is an OEM build and that forum/product supports that version.
    Please post your question to: http://forums.sdn.sap.com/index.jspa#44
    It could simply be you need to use a formula to convert the field. Click on the Formula Editor and the hit the F1 key and search on "date". Lots of info on how to convert todate and from date tostring...

    Hi Jamie,
    When you are trying to Browse Data of a field it is not poping up any window menas, it is unable to interact with database and get the data from database.
    Try to create a new report using ODBC with Xtreem Sample Database.  If you get the data in your report without any error then your connector is not working / unable to pull the data into your report.
