Insert Interval Given a set of non-overlapping intervals, insert a new interval into the intervals (merge if necessary). You may assume that the intervals were initially sorted according to their start times. Example 1: Given intervals [1,3],[6,9],
Name: 'INTERVAL' Description: Syntax: INTERVAL(N,N1,N2,N3,...) Returns 0 if N < N1, 1 if N < N2 and so on or -1 if N is NULL. All arguments are treated as integers. It is required that N1 < N2 < N3 < ... < Nn for this function to work co
最近实现一个按日期范围查询列表,例如输入的是日期 2015-11-01到2015-11-03,想得到1号到3号的数据, 执行 select * from table where create_date between '2015-11-01' and '2015-11-03' 结果是1号到2号的数据,这是因为时间范围是1号0时0分0秒到3号0时0分0秒之间的数据, 只需要把后面的日期加一天即可. 修改,使用date_add方法 select * from table where create_d
在Hiredmyway中: SELECT if(LENGTH(company_name) > 30, concat(SUBSTRING(company_name, 1, 27), '...'), company_name) AS org_name, count(id) AS num, org_id AS value
看到有一些博客说 between and 有不含边界的情况,于是测试了一把,记录如下.先说结论:between and 不存在不含边界的情况 1. between and 是包含边界的 id between 3 and 5 等价于 id >=3 and <=5; mysql> select * from t1; +----+--------+------+ | id | name | age | +----+--------+------+ | 1 | siri01 | 200 | |
