用Java调用Oracle存储过程总结(一)

一、无返回值的存储过程

测试表:

-- Create table

create table TESTTB

ID VARCHAR2(30),

NAME VARCHAR2(30)

tablespace BOM

pctfree 10

initrans 1

maxtrans 255

storage

initial 64K

minextents 1

maxextents unlimited

);


例: 存储过程为(当然了,这就先要求要建张表TESTTB,里面两个字段(I_ID,I_NAME)。

):

CREATE OR REPLACE PROCEDURE TESTA(PARA1 IN VARCHAR2, PARA2 IN VARCHAR2) AS

BEGIN

INSERT INTO BOM.TESTTB(ID, NAME) VALUES (PARA1, PARA2);

END TESTA;



在Java里调用时就用下面的代码:

package com.yiming.procedure.test;

import java.sql.CallableStatement;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

public class TestProcedureDemo1 {

public TestProcedureDemo1() {

}

public static void main(String[] args) {

String driver = "Oracle.jdbc.driver.OracleDriver";

String strUrl = "jdbc:Oracle:thin:@10.20.30.30:1521:vasms";

Statement stmt = null;

ResultSet rs = null;

Connection conn = null;

CallableStatement proc = null;

try {

Class.forName(driver);

conn = DriverManager.getConnection(strUrl, "bom", "bom");

proc = conn.prepareCall("{ call BOM.TESTA(?,?) }");

proc.setString(1, "100");

proc.setString(2, "TestOne");

proc.execute();

} catch (SQLException ex2) {

ex2.printStackTrace();

} catch (Exception ex2) {

ex2.printStackTrace();

} finally {

try {

if (rs != null) {

rs.close();

if (stmt != null) {

stmt.close();

}

if (conn != null) {

conn.close();

}

}

} catch (SQLException ex1) {

}

}

}

}



二、有返回值的存储过程(非列表)

例:存储过程为:

CREATE OR REPLACE PROCEDURE TESTB(PARA1 IN VARCHAR2, PARA2 OUT VARCHAR2) AS

BEGIN

SELECT NAME INTO PARA2 FROM TESTTB WHERE ID = PARA1;

END TESTB;


在Java里调用时就用下面的代码:

package com.yiming.procedure.test;

import java.sql.CallableStatement;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

import java.sql.Types;

public class TestProcedureDemo2 {

public static void main(String[] args) {

String driver = "Oracle.jdbc.driver.OracleDriver";

String strUrl = "jdbc:Oracle:thin:@10.20.30.30:1521:vasms";

Statement stmt = null;

ResultSet rs = null;

Connection conn = null;

CallableStatement proc = null;

try {

Class.forName(driver);

conn = DriverManager.getConnection(strUrl, "bom", "bom");

proc = conn.prepareCall("{ call BOM.TESTB(?,?) }");

proc.setString(1, "100");

proc.registerOutParameter(2, Types.VARCHAR);

proc.execute();

String testPrint = proc.getString(2);

System.out.println("=testPrint=is=" + testPrint);

} catch (SQLException ex2) {

ex2.printStackTrace();

} catch (Exception ex2) {

ex2.printStackTrace();

} finally {

try {

if (rs != null) {

rs.close();

if (stmt != null) {

stmt.close();

}

if (conn != null) {

conn.close();

}

}

} catch (SQLException ex1) {

}

}

}

}

注意,这里的proc.getString(2)中的数值2并非任意的,而是和存储过程中的out列对应的,如果out是在第一个位置,那就是proc.getString(1),如果是第三个位置,就是proc.getString(3),当然也可以同时有多个返回值,那就是再多加几个out参数了。
