oracle与jdbc的结合

import java.sql.SQLException;
import java.sql.Statement;

}

callableStatement.setint(1,值)//参数位置
callableStatement.setint("参数名",值);//参数名为定义的形参名字


注意过程调用中的参数命名表示法
位置、名称、混合(当出现名称时后面剩下的只能是名称表示)
但是JDBC中只能是位置或者名称

通过参数名称设置值，只能通过参数名称获得值

callableStatement.setInt("empno_p", 8888);
// out类型的参数
callableStatement.registerOutParameter("ename_p", Types.VARCHAR);
callableStatement.registerOutParameter("sal_p", Types.INTEGER);
boolean ex = callableStatement.execute();
System.out.println("ex=" + ex);
// if(callableStatement.execute()){
String ename = callableStatement.getString("ename_p");
int sal = callableStatement.getInt("sal_p");

同理：通过位置设置参数，只能通过位置获得对应out参数的值
