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，為普通類型，兩個輸出參數，其中一個為普通VARCHAR2型，另一個為特殊的記錄集類型。

（注：在數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

package JDBC;

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
????
????stmt.registerOutParameter(2,Types.CHAR); //輸出參數為普通參數
????stmt.registerOutParameter(3,OracleTypes.CURSOR); //輸出參數為結果集參數
?????
????stmt.executeQuery();
????
????rs = ((OracleCallableStatement) stmt).getCursor(3); //得到輸出結果集參數
????
????ResultSetMetaData rsmd = rs.getMetaData();
????int numberOfColumns = rsmd.getColumnCount();

????String str = stmt.getString(2);
????
??
????System.out.println("第二個參數為:"+str);
????System.out.println("結果集列數"+numberOfColumns);
????
????//列出結果集中的記錄
????ResultSetMetaData md = rs.getMetaData();
????int nColumns = md.getColumnCount();
????for (int i=1;i<=nColumns;i++){
?????System.out.print(md.getColumnName(i)+((i==nColumns)?"\n":"\t"));
?????if(i==2) System.out.print("\t");
????}
????
????while (rs.next()){
?????for(int i=1;i<=nColumns;i++){
?????System.out.print(rs.getString(i)+((i==nColumns)?"\n":"\t"));
????}
?????
????}
???}
???catch(SQLException ex){
????System.err.println(ex.getMessage()+"連數據庫有問題!");
???}
???
???return rs;
???
??}
??
}
?
?輸出結果為：

第二個參數為:Hello,may~
結果集列數4
