MaxCompute常用语句汇总(更新ing)

CREATE TABLE table_name (name string); 

创建内部表,并指定分区字段

CREATE TABLE table_name (name string) PARTITIONED BY (dt string); 

CREATE TABLE table_name (name string) 
PARTITIONED BY (dt string) LIFECYCLE 365;

CREATE EXTERNAL TABLE IF NOT EXISTS table_name
(
a type,
)
STORED BY 'com.aliyun.odps.CsvStorageHandler' -- (1)
WITH SERDEPROPERTIES (
'odps.properties.rolearn'='acs:ram::1811270634786818:role/aliyunodpsdefaultrole'
) -- (2)
LOCATION 'oss://oss-cn-shanghai-internal.aliyuncs.com/oss-odps-test/Demo/'; -- (3)(4)

CREATE TABLE  IF NOT EXISTS  table_name (name string); 

SHOW TABLES;

ALTER TABLE table_name ADD COLUMNS (col_name1 type1)

ALTER TABLE table_name RENAME TO new_table_name;

DROP TABLE table_name;

ALTER TABLE table_name CHANGE COLUMN old_col_name RENAME TO new_col_name;

1、创建一张表，结果为预期的表结构；

CREATE TABLE table2 (xxx);

2、把数据从原表导入到目标表，可以用SQL,比如:

INSERT OVERWRITE TABLE table2 SELECT * FROM table1;

3、更换表名：

ALTER TABLE table1 RENAME TO table1_bak;

ALTER TABLE table2 RENAME TO table1;

tunnel upload -fd '\t' E:\file.txt table_name  ;

desc table_name
