SQLTask使用样例

Account account = new AliyunAccount(S_AliyunAccount.AccessKey, S_AliyunAccount.SecretKey);

Odps odps = new Odps(account);

odps.setEndpoint("http://service.odps.aliyun.com/api");

odps.setDefaultProject("mplogchisal");

Instance instance;

try

{

instance = SQLTask.run(odps, "select theindex,thevalue,thetime from result_table order by theindex desc limit 100;");//一次最多返回10000条数据

instance.waitForSuccess();

List<Record> recordList = SQLTask.getResult(instance);

for (Record record : recordList)

{

System.out.println(record.get(0).toString()+","+record.get(1).toString()+","+record.get(2).toString());

}

instance = SQLTask.run(odps, "select count(theindex) from result_table;");

instance.waitForSuccess();

recordList = SQLTask.getResult(instance);

for (Record record : recordList)

{

System.out.println(record.get(0).toString());

}

}

catch (OdpsException e)

{

e.printStackTrace();
