| 一、先在oracle中編寫測試過程 1、首選建一個測試表 -- Create table
create table BOOK
(
BOOKID VARCHAR2(50) not null,
BOOKNAME VARCHAR2(50) not null,
PUBLISHER VARCHAR2(50) not null,
PRICE VARCHAR2(50) null
) 2、編寫ORACLE測試過程 CREATE OR REPLACE PACKAGE pkg_test
AS
TYPE myrctype IS REF CURSOR; PROCEDURE get (p_id VARCHAR2, p_str OUT VARCHAR2, p_rc OUT myrctype);
END pkg_test; / CREATE OR REPLACE PACKAGE BODY pkg_test
AS
PROCEDURE get (p_id VARCHAR2, p_str OUT VARCHAR2,p_rc OUT myrctype)
IS
sqlstr VARCHAR2 (500);
BEGIN
p_str := ‘Hello,may~‘;
IF p_id = ‘all‘ THEN
OPEN p_rc FOR
SELECT *
FROM BOOK;
ELSE
sqlstr :=
‘select *
from BOOK where BOOKID=:w_id‘;
OPEN p_rc FOR sqlstr USING p_id;
END IF;
END get;
END pkg_test; / 在這里我們建立了一個輸入參數(shù)，為普通類型，兩個輸出參數(shù)，其中一個為普通VARCHAR2型，另一個為特殊的記錄集類型。 （注：在數(shù)據庫端測試一下這個過程，以確保沒有問題，開始下面的操作~：） 二、編寫JAVA代碼測試過程 /*

import java.sql.*;
import oracle.jdbc.driver.*; public class proctest {
public static void main(String[] args) {
proctest pc = new proctest();
pc.ShowContent();
}
String sDBDriver="oracle.jdbc.driver.OracleDriver";
String sConnStr="jdbc:oracle:thin:@10.3.8.48:1521:ORADB";
Connection connect=null;
ResultSet rs = null;
public proctest(){
try{
Class.forName(sDBDriver);
}
catch(ClassNotFoundException e){
System.err.println(e.getMessage());
}
}
public ResultSet ShowContent()
{
try{
connect = DriverManager.getConnection(sConnStr,"SHUIBJ","SHUIBJ");
CallableStatement stmt = connect.prepareCall("{call PKG_TEST.GET(?,?,?)}");
stmt.setString(1,"all"); //輸入參數(shù)
stmt.registerOutParameter(2,Types.CHAR); //輸出參數(shù)為普通參數(shù)
stmt.registerOutParameter(3,OracleTypes.CURSOR); //輸出參數(shù)為結果集參數(shù)
stmt.executeQuery();
rs = ((OracleCallableStatement) stmt).getCursor(3); //得到輸出結果集參數(shù)
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount(); String str = stmt.getString(2);
System.out.println("第二個參數(shù)為:"+str);
System.out.p |
