用java调用oracle存储过程跟函数
创建测试用表：
CREATE TABLE USER
(
I_ID VARCHAR(50) NOT NULL,
I_NAME VARCHAR(50) NOT NULL
);
一：无返回值的存储过程
1，建立存储过程：
CREATE OR REPLACE
PROCEDURE TESTA(
PARA1 IN VARCHAR2,
PARA2 IN VARCHAR2)
AS
BEGIN
INSERT INTO USER
(I_ID,I_NAME
) VALUES
(PARA1, PARA2
);
END TESTA;
2，Java程序：
package com.hyq.src;
public class TestProcedureOne {
public TestProcedureOne() {
}
public static void main(String[] args ){
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521: hyq ";
Statement stmt = null;
ResultSet rs = null;
Connection conn = null;
CallableStatement cstmt = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(strUrl, " hyq ", " hyq ");
CallableStatement proc = null;
proc = conn.prepareCall("{ call HYQ.TESTA(?,?) }");
// proc = conn.prepareCall("begin HYQ.TESTA(?,?); end;");
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）
1，建立存储过程：
CREATE OR REPLACE
PROCEDURE TESTB(
PARA1 IN VARCHAR2,
PARA2 OUT VARCHAR2)
AS
BEGIN
SELECT I_NAME INTO PARA2 FROM TESTTB WHERE I_ID= PARA1;
END TESTB;
2，Java程序：
package com.hyq.src;
public class TestProcedureTWO {
public TestProcedureTWO() {
}
public static void main(String[] args ){
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:hyq";
Statement stmt = null;
ResultSet rs = null;
Connection conn = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(strUrl, " hyq ", " hyq ");
CallableStatement proc = null;
// proc = conn.prepareCall("{ call HYQ.TESTB(?,?) }");
proc = conn.prepareCall("begin HYQ.TESTB(?,?); end;");
proc.setString(1, "100");
proc.registerOutParameter(2, oracle.jdbc.OracleTypes.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) {
}
}
}
}
}
三：返回列表
由于oracle存储过程没有返回值，它的所有返回值都是通过out参数来替代的，列表同样也不例外，但由于是集合，所以不能用一般的参数，必须要用pagkage了.它是把游标（可以理解为一个指针），作为一个out 参数来返回值的.所以要分两部分:
1，建一个程序包：
CREATE OR REPLACE
PACKAGE TESTPACKAGE
AS
TYPE Test_CURSOR
IS
REF
CURSOR;
END TESTPACKAGE;
2，建立存储过程：
CREATE OR REPLACE
PROCEDURE TESTC(
PARA1 IN VARCHAR2,p_CURSOR OUT TESTPACKAGE.Test_CURSOR)
IS
BEGIN
OPEN p_CURSOR FOR SELECT * FROM HYQ.TESTTB WHERE I_ID= PARA1;
END TESTC;
3，Java程序：
package com.hyq.src;
public class TestProcedureTHREE {
public TestProcedureTHREE() {
}
public static void main(String[] args ){
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:hyq";
Statement stmt = null;
ResultSet rs = null;
Connection conn = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(strUrl, "hyq", "hyq");
CallableStatement proc = null;
proc = conn.prepareCall("{ call hyq.testc(?,?) }");
// proc = conn.prepareCall("begin hyq.testc(?,?); end;");
proc.setString(1, "100")
proc.registerOutParameter(2,oracle.jdbc.OracleTypes.CURSOR);
proc.execute();
rs = (ResultSet)proc.getObject(2);
while(rs.next())
{
System.out.println("<tr><td>" + rs.getString(1) + "</td><td>"+rs.getString(2)+"</td></tr>");
}
}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) {
}
}
}
}
四：调用函数返回列表
1，建一个程序包：
CREATE OR REPLACE
PACKAGE TESTPACKAGE
AS
TYPE Test_CURSOR
IS
REF
CURSOR;
END TESTPACKAGE;
2，建立函数：
CREATE OR REPLACE
FUNCTION TESTD(
PARA1 IN VARCHAR2)
RETURN TESTPACKAGE.Test_CURSOR
IS
rc TESTPACKAGE.Test_CURSOR;
BEGIN
OPEN rc FOR SELECT * FROM HYQ.TESTTB WHERE I_ID= PARA1;
return rc;
END TESTD;
3，Java程序：
package com.hyq.src;
public class TestProcedureTHREE {
public TestProcedureTHREE() {
}
public static void main(String[] args ){
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:hyq";
Statement stmt = null;
ResultSet rs = null;
Connection conn = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(strUrl, "hyq", "hyq");
CallableStatement proc = null;
proc = conn.prepareCall("{ call ? :=HYQ.TESTD(?) }");
// proc = conn.prepareCall("begin ? :=HYQ.TESTD(?); end;");
proc.registerOutParameter(1,oracle.jdbc.OracleTypes.CURSOR);
proc.setString(2, "100")
proc.execute();
rs = (ResultSet)proc.getObject(1);
while(rs.next())
{
System.out.println("<tr><td>" + rs.getString(1) + "</td><td>"+rs.getString(2)+"</td></tr>");
}
}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) {
}
}
}
}
