JAVA调用oracle存储过程实例

1、创建添加存储过程

CREATEORREPLACEPROCEDURE stu_proc(v_id INNUMBER, v_name INVARCHAR2, v_age INNUMBER) AS
BEGIN
INSERTINTO student(id, sname, age) values (v_id, v_name, v_age);
commit;
END;

JAVA调用添加存储过程



package com.ljq.test;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.SQLException;

publicclass ProceTest {

public static void main(String[] args) throws Exception {
Connection conn =null;
CallableStatement statement =null;
String sql ="{call stu_proc(?, ?, ?)}";
try {
conn = ConnUtils.getConnection();
statement = conn.prepareCall(sql);
statement.setInt(1, 6);
statement.setString(2, "laoli");
statement.setInt(3, 45);
//如果第一个结果是ResultSet对象，则返回true；如果第一个结果是更新、添加、修改或者没有结果，则返回 false
boolean issuccess=statement.execute();
//成功返回true，失败返回false
System.out.println(issuccess);
} catch (SQLException e) {
e.printStackTrace();
} finally {
ConnUtils.free(null, statement, conn);
}
}

}



创建删除存储过程语句



CREATEORREPLACEPROCEDURE stu_proc(v_id INNUMBER, v_msg OUT VARCHAR2) IS
v_flag NUMBER:=1;
BEGIN
SELECT o.id INTO v_flag FROM student o WHERE o.id=v_id;
DELETEFROM student o WHERE o.id=v_flag;
commit;
v_msg:='删除成功';
EXCEPTION
WHEN OTHERS THEN v_msg:='删除失败';
END;



java调用删除存储过程



package com.ljq.test;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Types;

publicclass ProceTest {

public static void main(String[] args) throws Exception {
Connection conn =null;
CallableStatement statement =null;
String sql ="{call stu_proc(?, ?)}";
try {
conn = ConnUtils.getConnection();
statement = conn.prepareCall(sql);
statement.setInt(1, 4);
statement.registerOutParameter(2, Types.VARCHAR);
statement.execute();
String msg=statement.getString(2);
System.out.println(msg);
} catch (SQLException e) {
e.printStackTrace();
} finally {
ConnUtils.free(null, statement, conn);
}
}

}



创建修改存储过程



CREATEORREPLACEPROCEDURE stu_proc
(
v_id INNUMBER,
v_name INVARCHAR2,
v_msg OUT VARCHAR2
) AS
v_flag number;
BEGIN
SELECT o.id INTO v_flag FROM student o WHERE o.id=v_id;
UPDATE student o SET o.sname=v_name WHERE o.id=v_id;
commit;
v_msg:='修改成功';
EXCEPTION
WHEN OTHERS THEN v_msg:='修改失败';
END;

statement.setInt(1, 3);

System.out.println(msg);

}
}
