1. 开通Data Lake Analytics与OSS服务
如果您已经开通，可以跳过该步骤。如果没有开通，可以参考：https://help.aliyun.com/document_detail/70386.html
进行产品开通服务申请。
2. 下载TPC-H测试数据集
可以从这下载TPC-H 100MB的数据集：
https://public-datasets-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/tpch_100m_data.zip
3. 上传数据文件到OSS
登录阿里云官网的OSS控制台：https://oss.console.aliyun.com/overview
规划您要使用的OSS bucket，创建或选择好后，点击“文件管理”，因为有8个数据文件，为每个数据文件创建对应的文件目录：
创建好8个目录如下：
点击进入目录，上传相应的数据文件，例如，customer目录，则上传customer.tbl文件。
上传好后，如下图。然后，依次把其他7个数据文件也上传到对应的目录下。
至此，8个数据文件都上传到了您的OSS bucket中：
oss://xxx/tpch_100m/customer/customer.tbloss://xxx/tpch_100m/lineitem/lineitem.tbloss://xxx/tpch_100m/nation/nation.tbloss://xxx/tpch_100m/orders/orders.tbloss://xxx/tpch_100m/part/part.tbloss://xxx/tpch_100m/partsupp/partsupp.tbloss://xxx/tpch_100m/region/region.tbloss://xxx/tpch_100m/supplier/supplier.tbl
4. 登录Data Lake Analytics控制台
https://openanalytics.console.aliyun.com/
点击“登录数据库”，输入开通服务时分配的用户名和密码，登录Data Lake Analytics控制台。
5. 创建Schema和Table
输入创建SCHEMA的语句，点击“同步执行”。
CREATE SCHEMA tpch_100m with DBPROPERTIES( LOCATION = 'oss://test-bucket-julian-1/tpch_100m/', catalog='oss');
（注意：目前在同一个阿里云region，Data Lake Analytics的schema名全局唯一，建议schema名尽量根据业务定义，已有重名schema，在创建时会提示报错，则请换一个schema名字。）
Schema创建好后，在“数据库”的下拉框中，选择刚刚创建的schema。然后在SQL文本框中输入建表语句，点击同步执行。
建表语句语法参考：https://help.aliyun.com/document_detail/72006.html
TPC-H对应的8个表的建表语句如下，分别贴入文档框中执行（LOCATION子句中的数据文件位置请根据您的实际OSS bucket目录相应修改）。（注意：目前控制台中还不支持多个SQL语句执行，请单条语句执行。）
CREATE EXTERNAL TABLE nation ( N_NATIONKEY INT, N_NAME STRING, N_ID STRING, N_REGIONKEY INT, N_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'oss://test-bucket-julian-1/tpch_100m/nation';CREATE EXTERNAL TABLE lineitem ( L_ORDERKEY INT, L_PARTKEY INT, L_SUPPKEY INT, L_LINENUMBER INT, L_QUANTITY DOUBLE, L_EXTENDEDPRICE DOUBLE, L_DISCOUNT DOUBLE, L_TAX DOUBLE, L_RETURNFLAG STRING, L_LINESTATUS STRING, L_SHIPDATE DATE, L_COMMITDATE DATE, L_RECEIPTDATE DATE, L_SHIPINSTRUCT STRING, L_SHIPMODE STRING, L_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'oss://test-bucket-julian-1/tpch_100m/lineitem';CREATE EXTERNAL TABLE orders ( O_ORDERKEY INT, O_CUSTKEY INT, O_ORDERSTATUS STRING, O_TOTALPRICE DOUBLE, O_ORDERDATE DATE, O_ORDERPRIORITY STRING, O_CLERK STRING, O_SHIPPRIORITY INT, O_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'oss://test-bucket-julian-1/tpch_100m/orders';CREATE EXTERNAL TABLE supplier ( S_SUPPKEY INT, S_NAME STRING, S_ADDRESS STRING, S_NATIONKEY INT, S_PHONE STRING, S_ACCTBAL DOUBLE, S_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'oss://test-bucket-julian-1/tpch_100m/supplier';CREATE EXTERNAL TABLE partsupp ( PS_PARTKEY INT, PS_SUPPKEY INT, PS_AVAILQTY INT, PS_SUPPLYCOST DOUBLE, PS_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'oss://test-bucket-julian-1/tpch_100m/partsupp';CREATE EXTERNAL TABLE customer ( C_CUSTKEY INT, C_NAME STRING, C_ADDRESS STRING, C_NATIONKEY INT, C_PHONE STRING, C_ACCTBAL DOUBLE, C_MKTSEGMENT STRING, C_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'oss://test-bucket-julian-1/tpch_100m/customer';CREATE EXTERNAL TABLE part ( P_PARTKEY INT, P_NAME STRING, P_MFGR STRING, P_BRAND STRING, P_TYPE STRING, P_SIZE INT, P_CONTAINER STRING, P_RETAILPRICE DOUBLE, P_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'oss://test-bucket-julian-1/tpch_100m/part';CREATE EXTERNAL TABLE region ( R_REGIONKEY INT, R_NAME STRING, R_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'oss://test-bucket-julian-1/tpch_100m/region';

Data Lake Analytics支持“同步执行”模式和“异步执行”模式。“同步执行”模式下，控制台界面等待执行结果返回；“异步执行”模式下，立刻返回查询任务的ID。
点击“执行状态”，可以看到该异步查询任务的执行状态，主要分为：“RUNNING”，“SUCCESS”，“FAILURE”。
点击“刷新”，当STATUS变为“SUCCESS”时，表示查询成功，同时可查看查询耗时“ELAPSE_TIME”和查询扫描的数据字节数“SCANNED_DATA_BYTES”。
8. 查看查询历史
点击“执行历史”，可以看到您执行的查询的历史详细信息，包括：
1）查询语句；
2）查询耗时与执行具体时间；
3）查询结果返回行数；
4）查询状态；
5）查询扫描的字节数；
6）结果集回写到的目标OSS文件（Data Lake Analytics会将查询结果集保存用户的bucket中）。
查询结果文件自动上传到用户同region的OSS bucket中，其中包括结果数据文件和结果集元数据描述文件。
{QueryLocation}/{query_name}|Unsaved}/{yyyy}/{mm}/{dd}/{query_id}/xxx.csv
{QueryLocation}/{query_name}|Unsaved}/{yyyy}/{mm}/{dd}/{query_id}/xxx.csv.metadata其中QueryLocation为：
