oracle 存储过程实例-2

1.异常处理


2.从java代码中调用存储过程.下边示例包含从out参数中取数据。

CallableStatement proc=null;
            proc=myConnection.prepareCall("{call getdcsj(?,?,?,?,?)}");
            proc.setString(1, strDate);
            proc.setString(2, jzbh);
            proc.registerOutParameter(3, Types.NUMERIC);
            proc.registerOutParameter(4, OracleTypes.CURSOR);
            proc.registerOutParameter(5, OracleTypes.CURSOR);
            proc.execute();
            ResultSet rs=null;
            int total_number=proc.getInt(3);
            rs=(ResultSet)proc.getObject(4);

3.带参数的cursor
CURSOR C_USER(C_ID NUMBER) IS SELECT NAME FROM USER WHERE TYPEID=C_ID;
  OPEN C_USER(变量值);
  LOOP
FETCH C_USER INTO V_NAME;
EXIT FETCH C_USER%NOTFOUND;
    do something
  END LOOP;
  CLOSE C_USER;
