select * from city limit 5,10

I'm sorry, as an AI language model, I don't have access to any database to execute SQL queries. However, I can explain what this query does:

The query selects all columns from the table "city" and limits the result set to return 10 rows, starting from the 6th row (skipping the first 5 rows).

In other words, it retrieves data from rows 6 to 15 of the "city" table.

hive> select * from weathe limit 10; OK 2023-04-01 m 22 12 � W� 3� � 2023-04-02 � 20 13 �~4 � 4� � 2023-04-03 18 9 �~� � 2� � 2023-04-04 � 12 6 � � 2� � 2023-04-05 17 9 �~� � 0� � 2023-04-06 � 18 5 �~t � 3� � 2023-04-07 � 16 4 t � 3� � 2023-04-08 m 22 8 t~� W� 4� � 2023-04-09 � 22 10 � W� 2� � 2023-04-10 28 11 � W� 1� � Time taken: 0.136 seconds, Fetched: 10 row(s)

这段代码执行了一个查询语句，从weathe表中选择所有列，并限制结果集大小为10行。查询结果显示了weathe表中的前10行数据。每行数据包括w_date、hmax、hmin、weathertype、windy和city列的值。这里出现了一些乱码，可能是因为输出编码方式不正确或者涉及到的数据存在问题。

SELECT *, @rownum := @rownum + 1 AS tmp, @incrnum := CASE WHEN @rowtotal = ${field} THEN @incrnum WHEN @rowtotal := ${field} THEN @rownum END AS rownum FROM (SELECT * from (SELECT * from aqi_hour_site WHERE 1=1 <if test="cityCode != null and cityCode != ''"> AND city_code = #{cityCode} </if> <if test="arrayList!=null and arrayList.size()>0"> AND site_code in <foreach collection="arrayList" item="item" index="index" open="(" separator="," close=")">#{item}</foreach> </if> ORDER BY data_time desc LIMIT 2000) d GROUP BY site_code <if test="dataSort==1">ORDER BY ${field} asc</if> <if test="dataSort==2">ORDER BY ${field} desc</if> ) as a, (SELECT @rownum := 0, @rowtotal := NULL, @incrnum := 0) b

这段代码看起来像是一个SQL查询语句，其中包含了一些参数以及条件筛选。具体来说，它查询了一个叫做aqi_hour_site的表，并根据一些条件进行筛选，比如cityCode和site_code。查询结果按照data_time进行降序排列，并且只取前2000条数据。然后，再对结果按照site_code进行分组，并且使用MySQL的变量来计算每个分组的行号，以便于后续的排序。最后，根据参数dataSort的值，对结果进行升序或降序排序。
