Hive表操作的源程序代码是基于Hadoop MapReduce框架的,使用Java语言开发。以下是一个简单示例:
创建表:
CREATE TABLE table_name (
column1 data_type,
column2 data_type,
...
)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY ','
STORED AS TEXTFILE;
查询表:
SELECT column1, column2, ...
FROM table_name
WHERE condition;
插入数据:
INSERT INTO table_name (column1, column2, ...)
VALUES (value1, value2, ...);
更新数据:
UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;
删除数据:
DELETE FROM table_name
WHERE condition;
删除表:
DROP TABLE table_name;
