我的代码:
--创建表
CREATE   TABLE   T  
(COL1   NUMBER   PRIMARY   KEY,   COL2   VARCHAR2(10));
insert   into   t   values   (1,   'Hello ');
insert   into   t   values   (2,   'World ');
--创建包和声明函数
CREATE   OR   REPLACE
PACKAGE   T_PKG   AS
    G_COUNT     NUMBER   :=   0;
    FUNCTION   GET_VALUE(p_col1   NUMBER)   RETURN   VARCHAR2;
    PROCEDURE   GET_VALUE2(p_col1   NUMBER,   p_col2   OUT   VARCHAR2);
END;

--创建包中函数的实现
create   OR   REPLACE
PACKAGE   BODY   T_PKG   AS
    FUNCTION   GET_VALUE(p_col1   NUMBER)   RETURN   VARCHAR2
    IS
        v_value   VARCHAR2(10);
    BEGIN
        g_count   :=   g_count   +   1;
        SELECT   col2   INTO   v_value   FROM   t   WHERE   col1   =   p_col1;
        RETURN   v_value|| ',   Execution   Count   =   '||g_count;
    END;    
    PROCEDURE   GET_VALUE2(p_col1   NUMBER,   p_col2   OUT   VARCHAR2)
    IS
    BEGIN
        g_count   :=   g_count   +   1;
        SELECT   col2   INTO   p_col2   FROM   t   WHERE   col1   =   p_col1;
        p_col2   :=     p_col2|| ',   Execution   Count   =   '||g_count;
    END;
END;
--在java中的实现------------
import   java.sql.*;
import   oracle.jdbc.driver.OracleDriver;

public   class   JDBCDemo     {
    static   Connection   conn;
   
    public   static   void   main(String[]   args)   {
        try   {
            DriverManager.registerDriver(   new   OracleDriver());
            conn   =   DriverManager.getConnection( "jdbc:oracle:thin:@localhost:1521:orcl ",   "ora15 ",   "oracle ");
