php-check:检查您的代码是否存在语法错误和错误
这段代码存在一些语法错误。在使用INSERT OVERWRITE语句时,需要指定目标表,而你的代码中没有指定目标表。此外,你还需要使用INSERT语句来将查询结果插入到指定的目录中。
以下是修正后的代码:
```sql
INSERT OVERWRITE DIRECTORY '/home/map/chenlinyu/task2'
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
SELECT t2.city_name, COUNT(*) AS count
FROM map_huiyan_short_stay t1
JOIN map_huiyan_long_stay_with_area t2 ON t1.cuid = t2.cuid
WHERE t2.event_day = 20230605
AND t1.loc_x > 12993523
AND t1.loc_x < 13012467
AND t1.loc_y > 4773079
AND t1.loc_y < 4789463
GROUP BY t2.city_name;
```
请确保将目标表替换为你想要插入数据的实际目录,并执行修正后的代码。
