Help me to solve the simple but complicated problem ??

Question

I wanted to use oracle stored function in my programme(inserts/update the data into multiple tables based certain values in related tables). I need to pass many values from java to calling function is there any way to pass my java values into oracle function as an array of values or by any other means and use the same values in my stored function? (Except val1, val2, val3, .. etc to function) .
Advance thanks to every body trying to reply

Answer 1

Oracle JDBC driver is JDBC 2.0 compliant. Right ?
And in JDBC 2.0 there exists the interface java.sql.Array
Oracle JDBC provides the class oracle.sql.ARRAY Have you thought of using it ? It may be what you are looking for.
Here is an example that comes with Oracle JDBC driver...
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.oracore.Util;
import oracle.jdbc.driver.*;
import java.math.BigDecimal;
public class ArrayExample
  public static void main (String args[])
    throws Exception
    // Register the Oracle JDBC driver
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
    // Connect to the database
    // You need to put your database name after the @ sign in
    // the connection URL.
    // The sample retrieves an varray of type "NUM_VARRAY",
    // materializes the object as an object of type ARRAY.
    // A new ARRAY is then inserted into the database.
    Connection conn =
      DriverManager.getConnection ("jdbc:oracle:oci8:@",
                                   "scott", "tiger");
    // It's faster when auto commit is off
    conn.setAutoCommit (false);
    // Create a Statement
    Statement stmt = conn.createStatement ();
    try
      stmt.execute ("DROP TABLE varray_table");
      stmt.execute ("DROP TYPE num_varray");    
    catch (SQLException e)
      // the above drop statements will throw exceptions
      // if the types and tables did not exist before. Just ingore it.
    stmt.execute ("CREATE TYPE num_varray AS VARRAY(10) OF NUMBER(12, 2)");
    stmt.execute ("CREATE TABLE varray_table (col1 num_varray)");
    stmt.execute ("INSERT INTO varray_table VALUES (num_varray(100, 200))");
    ResultSet rs = stmt.executeQuery("SELECT * FROM varray_table");
    showResultSet (rs);
    //now insert a new row
    // create a new ARRAY object   
    int elements[] = { 300, 400, 500, 600 };
    ArrayDescriptor desc = ArrayDescriptor.createDescriptor("NUM_VARRAY", conn);
    ARRAY newArray = new ARRAY(desc, conn, elements);
    PreparedStatement ps =
      conn.prepareStatement ("insert into varray_table values (?)");
    ((OraclePreparedStatement)ps).setARRAY (1, newArray);
    ps.execute ();
    rs = stmt.executeQuery("SELECT * FROM varray_table");
    showResultSet (rs);
    // Close all the resources
    rs.close();
    ps.close();
    stmt.close();
    conn.close();
  public static void showResultSet (ResultSet rs)
    throws SQLException
    int line = 0;
    while (rs.next())
      line++;
      System.out.println("Row "+line+" : ");
      ARRAY array = ((OracleResultSet)rs).getARRAY (1);
      System.out.println ("Array is of type "+array.getSQLTypeName());
      System.out.println ("Array element is of type code "+array.getBaseType());
      System.out.println ("Array is of length "+array.length());
      // get Array elements           
      BigDecimal[] values = (BigDecimal[]) array.getArray();
      for (int i=0; i<values.length; i++)
        BigDecimal value = (BigDecimal) values;
System.out.println(">> index "+i+" = "+value.intValue());
