How to get varchar size using ResultSetMetaData.getColumnTypeName()?

I am querying a table in my DB and I can get the SQL Datatype of varchar for a particular column, but how can I get the length?
i am using the method ResultSetMetaData.getColumnTypeName(i)

doh! i overlooked that method in the javadocs. kept thinking it was getColumnCount. Thanks a lot!

    the first line of information always off chart, so I usually do a few interval to get constant result.
    if you use linux

    Hi,
    As above, how to get the size of a hard disk by using Java.
    Thanks you!
    Alex

    I would be interested in the answer of this question, too.
    In core Java there is no way to find it out in a platform independent manner because of the hardware abstraction of the VM. So my only idea is to write a native library for doing this and colling it via JNI

    Hi,
    Am facing the same issue stated above that I couldnt get all the records in the table that am querying in the Proxyservice.
    For example:
    fn-bea:execute-sql('EsbDataSource', 'student', 'select Name from StudentList' ) is the query that am using to fetch the records from the table called StudentList which contains more than one records like
    Id Name
    01 XXX
    02 YYY
    03 ZZZ
    I tried to assign the result of the above query in a variable and while trying to log the variable, I can see the below
    <student>
    <Name>XXX</Name>
    </student>
    I want to have all the records from my table in xml format but it's not coming up. I get the value only from the first row of my table.
    Please suggest.
    regards,
    Venkat

    I referred PLKO got the Task List Type (PLNTY), Group(PLNNR), Group Counter(PLNAL), Plant(werks).

    How to get the ARBID with respect to Groupcounter 1 alone.
    If a get the ARBID , I can get the ARBPL from CRHD.

    HI,
    Use PLAS Table also.  you have to use PLKO> PLAS> PLPO.
    Pass PLNNR & PLNAL in PLAS and get PLNNR & PLNKN.
    Then pass these into PLPO.

    This question looks like it is really for the Oracle RDBMS and not for Berkeley DB. In BDB, we do not have a notion of tablespace size. What database product are you using?
