用java调用oracle存储过程和函数
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) {
????? }
??? }
? }
}
