使用Java调用Oracle数据库的存储过程实例

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 T_TEST (I_ID,I_NAME) VALUES (PARA1, PARA2);
END TESTA;
2、相应的JAVA程序
import java.sql.*;
import java.io.OutputStream;
import java.io.Writer;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import oracle.jdbc.driver.*;
public class TestProcedureOne {
public TestProcedureOne() {
}
public static void main(String[] args ){
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@192.168.10.216:1521:ctbu";
Statement stmt = null;
ResultSet rs = null;
Connection conn = null;
CallableStatement cstmt = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(strUrl, "dbname", "password");
CallableStatement proc = null;
proc = conn.prepareCall("{ call dbname.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）
1、存储过程为
CREATE OR REPLACE PROCEDURE TESTB(PARA1 IN VARCHAR2,PARA2 OUT VARCHAR2) AS
BEGIN
SELECT INTO PARA2 from TESTTB WHERE I_ID= PARA1;
END TESTB;
2、JAVA代码
public class TestProcedureTWO {
public TestProcedureTWO() {
}
public static void main(String[] args ){
String driver = "oracle.jdbc.driver.OracleDriver";
String strUrl = "jdbc:oracle:thin:@192.168.10.216:1521:ctbu";
Statement stmt = null;
ResultSet rs = null;
Connection conn = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(strUrl, "dbname", "password");
CallableStatement proc = null;
proc = conn.prepareCall("{ call HYQ.TESTB(?,?) }");
proc.setString(1, "100");
proc.registerOutParameter(2, Types.VARCHAR);
proc
