这是我的MySql代码, BETWEEN DATE_SUB(CURDATE(), INTERVAL (IF(DAYNAME(CURDATE()) = 'Monday',3,1)) DAY) AND DATE_SUB(CURDATE(), INTERVAL (IF(DAYNAME(CURDATE()) = 'Monday',1,1)) DAY) 在Sql Server2008中,我知道如何在没有时间的情况下拉出前一天的数据,但我一直无法将这行代码从MySql转换...
我们发现 代码中的每一句都有分号; 而;是SQL语句结束的意思 所以MySQL编程时 我们要改变MySQL的结束符 delimiter // 2)定义变量 declare 变量名 数据类型 default 默认值; 3)赋值 set 变量名=值; 4)函数参数 create function ad(a1 int,a2 int) returns int declare 声明 default 默认的 delimiter 分隔符 定...
InSQLServer, you can use DATEADD function to add an interval in the specified units to the datetime value. In MySQL, you can use TIMESTAMPADD function. Note that unit values can be different inSQLServer DATEADD and MySQL TIMESTAMPADD functions. SQLServer: -- Add 3 daysSELECTDATEADD(dd,3,'...

总结: SQL dateadd和datediff是两个常用的日期和时间函数,用于在SQL语句中对日期进行计算和间隔的计算。dateadd函数用于向指定日期或时间添加指定的时间间隔,而datediff函数用于计算两个日期或时间之间的时间间隔。它们在数据库开发中应用广泛,可以帮助开发人员实现各种日期和时间相关的业务逻辑。相关...
SQL provides a DATEADD() function that adds a date or time interval to a specific date and returns the updated date. Similarly, MySQL and MariaDB have DATE_ADD() and ADDDATE() functions to add an interval to a date/time, and SQLite provides a DATE() function that can be used to add...
