java months between,ORACLE函数MONTHS_BETWEEN

因系统折旧月份是按当月是否满15天来算是否为一个月,故此研究了下MONTHS_BETWEEN已适应折旧的逻辑 官网函数说明: MONTHS_BETWEEN returns number of months between dates date1 and date2. MONTHS_BETWEEN返回日期date1和date2之间的月数。如果date1晚于date2,则结果为正数。如果date1早于date2,则结果为负。 ’) ) “Months” FROM DUAL; Months 1.03225806` months_between算法为01-01-2020到02-02-2020,2020年一月份算一个整月,不整的为 2月份的两天, 于是 MONTHS_BETWEEN (TO_DATE(’02-02-2020′,’MM-DD-YYYY’),TO_DATE(’01-01-2020′,’MM-DD-YYYY’) ) =

SQL谓词 BETWEEN

SQL谓词 BETWEEN 大纲 scalar-expression BETWEEN lowval AND highval 参数 scalar-expression - 一种标量表达式(最常见的是数据列 注意,必须按升序指定BETWEEN值; 例如BETWEEN 21 AND 18这样的谓词将返回空字符串。 如果标量表达式的值都不在指定的范围内,则BETWEEN返回空字符串。 与大多数谓词一样,BETWEEN可以使用NOT逻辑运算符进行反转。 BETWEEN和NOT BETWEEN都不能用于返回NULL字段。 返回NULL字段使用IS NULL。 NOT BETWEEN的示例如下: SELECT Name,Age FROM Sample.Person WHERE Age NOT BETWEEN 20 AND 55 ORDER BY Age 这将返回 排序类型 BETWEEN通常用于按数字顺序排序的数值范围。 但是,BETWEEN可用于任何数据类型值的排序规则序列范围。 BETWEEN使用与它所匹配的列相同的排序规则类型。

    sql 中 between 的边界问题 ---- between 边界:闭区间,not between 边界:开区间

    BETWEEN 用以查询确定范围的值,这些值可以是数字,文本或日期 。 BETWEEN 运算符是闭区间的:包括开始 和 结束值 。 如下: 我有一个表只有4行数据: 用 between 查,是包含前后边界值的: not between 则是不包含前后边界的 补记: 日期边界问题,如:'2010-04-21 16:42:39', '2010-04-23 16:42:39' 如果用 between '2010-04-21' and '2010-04-23' ,这样'2010-04-23 16:42:39' 这条记录查不到 因为它的边界值是

    Oracle中BETWEEN ... AND的作用

    我们看下Oracle中,是如何操作BETWEEN ... AND的。 官方手册上,BETWEEN ... AND定义如下, expr1 [ NOT ] BETWEEN expr2 AND expr3 其中expr可以是数字、字符、或者日期表达式。 这两种表达,是等价的, expr1 NOT BETWEEN expr2 AND expr3 NOT (expr1 BETWEEN expr2 AND expr3) 这两种表达,是等价的,expr2 less 若朋友们使用其他的数据库,可以留言告诉我们在不同的数据库中,BETWEEN ... AND都出现怎样不同的现象? 参考: https://www.w3school.com.cn/sql/sql_between.asp

    months_between用于计算两个日期之间相差的月数 语法:months_between(date1,date2) 举例a 20210201与20210301 select months_between yyyy-mm-dd'))diff from dual --函数的两个参数都是时间格式,可以通过to_date()函数转为时间格式 举例b 20210201与20210302 select months_between ,'yyyy-mm-dd'),to_date('20210302','yyyy-mm-dd'))diff from dual 举例c 20210201与20210128 select months_between

    BI-SQL丨BETWEEN

    BETWEEN操作符 BETWEEN操作符属于WHERE语句的补充。通常与AND搭配使用,可以用来限定数据范围。 可以是数值,可以是文本,也可以是日期。 相较于PowerBI而言,SQL中的BETWEEN更加灵活。PowerBI中除了日期函数系列有类似的函数以外,并没有单独的BETWEEN函数。 基础语法 SELECT 列名称(*) FROM 表名称 WHERE 列名称 BETWEEN 条件1 AND 条件2 注意事项 BETWEEN...AND的语句表达属于数据库通用语句之一,在大部分的数据库中此语句都是可用的 不同的数据库BETWEEN...AND取值是有区别的,有的是包含两端,有的不包含两端,有的只包含一端,因此在使用的时候需要确认当前数据库语言的取值区别。 SELECT * FROM 产品表 WHERE 成本 NOT BETWEEN 10 AND 50 结果如下: 这里是白茶,一个PowerBI的初学者。
