ResultSet to Array/Vector

Does anyone have some code that read's data from a resultSet and puts it into a 3D array or Vector that I could look at? (3D array examples would be better).
The code I have is giving me a few problems and I was wondering how other people have implemented the above.

Try that buddy. this is similar taking it from an object and adding it to a vector and the only reason i am returning it cause i am using the vector in a jsp page...
public Vector getRecordE(String ProjectID){
               ResultSet TPRO_E=null;
               try{
               PreparedStatement P_TPRO=conOrcl.prepareStatement("select * from recorde where PROJ_EXT_PROJ_ID=?");
          //assign the ? to the argument passed
               P_TPRO.setString(1,ProjectID);
          //execute the statement
               P_TPRO.execute();
          //execute the query
               TPRO_E= P_TPRO.executeQuery();
          //looping through the resultSet
          while (TPRO_E.next()){
          //create an instance of the class
               JavaBeans ItemE = new JavaBeans();
          // set it to the Bean
               ItemE.setTwinId(TPRO_E.getString("twin_proj_id"));
               ItemE.setprojPhaseCode(TPRO_E.getString("proj_phase_cd"));
               ItemE.setEfund_cd(TPRO_E.getString("fund_cd"));
          //add the object to the vector
     V_itemsE.addElement(ItemE);
          }catch(SQLException w){
               System.out.println(w.getMessage());
          //returning the vector
                    return V_itemsE;
hope it helps... pretty close

  • Why is conversion from array/vector of chars to jcharArray not working?

    This really is an array/vector of chars, not a string (i.e. not a char* string).
    jcharArray convert(JNIEnv* env, const std:vector<char> vect)
         int size = vect.size();
         jcharArray arr = env->NewCharArray( size );
         env->SetCharArrayRegion( arr, 0, size, ( jchar * ) &( vect[ 0 ] ) );
         return arr;
    }It returns garble to Java instead of the characters put into the vector. What am I doing wrong?

    Presumably you have some reason to think that vect[ 0 ] is going to represent a contigous memory segement for the rest of the characters.
    A java "char" and C "char" are not the same size.

  • Converting a ResultSet to a Vector

    hiya i gota question...(my code is below)...im doing a search query which searches the database for the search field and then these gets the results into a ResultSet.
    i then need to print these out in a table kinda thing but at the moment the results are bunched together. this is a problem cos the <A HREF> link is highlighting all the results whereas each result needs to be linked to another page.
    THEREFORE i think i need to convert the resultset to a vector and then print out the vector one by one onto the jsp page.
    Enumeration enum = v.elements();
    while(enum.hasMoreElements()) {
    String s = (String) enum.nextElement();
    query = "SELECT * FROM Login_Details LD, Personal_Details PD, Education E, Work_Experience WE, Skills S WHERE

  • Array, Vector, or Hashtable?

    I'm wondering what the best way to populate a names list for a chat program is. I need it to be able to set a unique identification to whoever joins the chat. It has to be able to tell who left, and be able to take just that persons name out of the list.

    A Hashtable would let you match up user IDs to sockets, if that's your underlying design....

  • Can you store the resultSet from a query into a vector?

    I am totally frustrated. How the heck does one store the results of a query (resultSet) in a vector so that I can get the vector from my jsp page to display in a table.? searchRS is my resultSet from stmt.executeQuery().
    public Vector storeResultSet ()throws SQLException
    int dataType;
    Vector rows = new Vector();

  • Size restrictions on arrays and vectors

    Hi all!!!
    I want to know whether there is any restriction on maximum size of array and vectors.
    If I have thousands of records to be displayed on browser through JSP, can I initialise the arrays/vectors with that no.
    Whether it will have adverse effect on performance.
    Thanks in anticipation

    Array lists (and vectors) use an array as backing data store. And since array indices are ints, the maximum number of elements in an array list is Integer.MAX_VALUE (2 ^ 31 - 1).
    About the performance: if you know how many elements you are going to add (albeit not precisely), you can create the array list with an initial capacity. This will improve performance because a new array is created when an element is to be added but the capacity has been reached.
    Kind regards,
      Levi

  • Can Vector contain ResultSet which is a Interface

    What i am trying is to execute 3 different SQL in a Bean and try it to transfer in a JSP.I am using Vector for this work.I am putting the ResultSet in the Vector and transfer that Vector to the Jsp,In which i am displaying the Result.
    I wanted to know that Is it possible to do the thing in this way.Or some other way is there.
    Could any one tell me the Solution.

    May be I 'm wrong, but the objets implementing the ResultSet interface
    must be serializable and have a public default constructor if you want
    to serialize/deserialize them. I don't think the most know drivers
    are offering you these features.
    Even if it's feasible, I don't think serializing a whole data set is
    really a good idea, because of the big overhead of doing this.
    You'd better convert the resultSet into smaller objects and
    only pass a set of them to your jsp only under request,
    not the whole thing once.
    Hope this helps

  • Add Vector or ResultSet to JComboBox

    i now got the 1.5 to work without the invocation errors, the whole reason i needed the array is as such
    setting array

    icl.updateTime(rows);
    but still getting a error with the bloody array saying "type java.util.vector does not take parameters". i no you guys are really good at java, so tried not to have a go just need to be pointed to a tutorial or some code that might explain this better to me.

  • Comparing two ResultSet

    Hi Everybody,
    Can anybody tell me is there any method to compare the contents of two ResultSets and decide whether they are same or not.
    Thanks

    Yes,
    Create a method that takes the two result sets, get the metada of the table and compare field by fiel.
    Another alternative is to copy the ResultSet to a Vector and than compare it.

  • ResultSet from Java Stored Procedures

    Hi,
    How do I obtain a resultset from a Java Stored Procedure?
    My stored procedure, deployed in Oracle8i, has Database package as sample.Have published setConnection() and getDept() methods.
    Code for Java Stored Procedure:
    package SPPackage;
    import java.sql.*;
    public class StoredProcApplication {
    protected static Connection connection = null;
    protected static Statement stmt = null;
    protected static ResultSet res = null;
    public static void setConnection() throws SQLException {
    connection = new oracle.jdbc.driver.OracleDriver().defaultConnection();
    public static void getDept(Object[] obj) throws SQLException {
    if (connection == null) {
    setConnection();
    if (stmt == null) {
    stmt = connection.createStatement();
    if (res == null) {
    res = stmt.executeQuery("select * from DEPT");
    obj[0] = res;
    Code for TesterApplication :
    package SPPackage;
    import java.sql.*;
    public class TesterApplication {
    private static final String URL = "jdbc:oracle:thin:@sandeep:1521:oracle8i";
    private static final String userId = "sandeep";
    private static final String password = "sandeep";
    private Connection connection;
    private CallableStatement stmt;
    private ResultSet res;
    public void setConnection() throws ClassNotFoundException,SQLException {
    Class.forName("oracle.jdbc.driver.OracleDriver");
    connection = DriverManager.getConnection(URL,userId,password);
    public void getResultFromSP() throws SQLException {
    //prepare to call the stored procedure
    stmt = connection.prepareCall("{call sample.getDept(?)}");
    //register the OUT parameters
    stmt.registerOutParameter(1,Types.OTHER);
    //execute the query
    stmt.execute();
    ResultSet res = (ResultSet)stmt.getObject(1);
    while (res.next()) {
    System.out.print(res.getInt(1) + " | " );
    System.out.print(res.getString(2) + " | " );
    System.out.print(res.getString(3) + " \n " );
    public TesterApplication() throws SQLException,ClassNotFoundException {
    try {
    setConnection();
    getResultFromSP();
    } finally {
    if (res != null) { res.close(); res = null; }
    if (stmt != null) { stmt.close(); stmt = null; }
    if (connection != null) { connection.close(); connection = null; }
    public static void main(String[] args) {
    try {
    TesterApplication ta = new TesterApplication();
    } catch (Exception e) {
    System.err.println("Error while executing stored procedure " + e.getMessage());
    e.printStackTrace();
    When I run the TesterApplication, I get the following exception :
    java.sql.SQLException: Invalid column type: get_internal_type
    at oracle.jdbc.dbaccess.DBError.check_error(Compiled Code)
    at oracle.jdbc.driver.OracleStatement.get_internal_type(Compiled Code)
    at oracle.jdbc.driver.OracleCallableStatement.registerOutParameter(Compiled Code)
    Also, if I want to execute the ResultSet in the stored proc itself, and return the values as Arrays of int[], and String[], how do I do it?By default the you can populate only int[0], String[0] , i.e. only one value!!!
    if my statement is unknown, i.e, it might return a combination of updates and resultsets, how do I go about processing the result?
    Please advise!!

    Hi kkirk,
    I found the post you mentioned.Well it dates back to November 1999 - "Problem returning resultset or ARRAY from java stored proc" by Stuart Popejoy ([email protected]).Too bad, it is still not solved!!
    I am not very good at PL/SQL.However, it would still be helpful, if you could post the code here, or at my email address.
    Meanwhile, I was trying this during the week-end.There seems to be a glimmer of hope!!
    Let me know, if this makes sense :
    CallableStatement cs = connection.prepareCall("begin open ? for select * from dept; end");
    try {
    cs.registerOutParameter(1,OracleTypes.CURSOR);
    ResultSet res = ((OracleCallableStatement)cs).getCursor(1);
    while (res.next()) {
    //get the values
    } catch (Exception e) {
    e.printStacktrace();
    However, I am getting an exception trace

  • JDBC:Count Array. SQL query works but fails in JDBC

    Hi,
    I'm using the following SQL query
    "SELECT red.id, name, count(green.id) FROM red, green WHERE area = 'northeast' AND red.id = zid GROUP BY name"
    It executes perfectly from the DB command line giving me the results.
    However when I call it from within JDBC i am getting null values.
    My JDBC call ia as follows( Where lst is the above query)
    rs = st.executeQuery(lst);
    while(rs.next()){
    nidV.addElement(rs.getString("red.id"));
    nnmV.addElement(rs.getString("name"));
    nnumV.addElement(rs.getString("count(green.id)"));
    I do realize that many folks use Integer for count queries but I pull them with as Strings all the time so that's not it.
    The one diffrence between this and my other count queries is that this one returns an array (Vector) of counts.
    Any ideas?

    the problem is probably:
    SELECT red.id, name, count(green.id) ...
    nnumV.addElement(rs.getString("count(green.id)"));you can either use an alias for the column;
    SELECT red.id, name, count(green.id) COUNT_VAR
    nnumV.addElement(rs.getObject("COUNT_VAR"));or use getObject(3) as suggested by drclap.
