DATEADD() in SQL Server, DATE_ADD() in MySQL, ADDDATE() in MariaDB, etc. However, In Postgres, there is no such function that offers the same functionality. Now the question is how to Add intervals to the DateTime value in Postgres. Well!
这些知识不仅适用于SQLite,也适用于其他关系型数据库如MySQL和PostgreSQL,只需调整连接方式和SQL语法。在日常开发中,掌握时间数据的存储和管理,将对你处理复杂的数据任务有极大的帮助。希望这篇文章能够为你在数据处理过程中提供一些启发和便利。
在ZonedDateTime类中,根据传递给它的参数,有三种类型的now()方法。now()ZonedDateTime 类的now() 方法用于从默认时区的系统时钟中获取当前日期时间。该方法将返回基于默认时区的系统时钟的ZonedDateTime,以获取当前日期时间。区域和偏移量将根据时钟中的时区来设置。
PostgreSQL:TO_CHAR(NOW(), 'YYYY-MM-DD') Oracle:TO_CHAR(SYSDATE, 'YYYY-MM-DD') 日期比较 存储过程常用于执行日期比较,以实现如“查找过去一周内的记录”等功能,这通常涉及到使用日期函数来生成时间范围,并在WHERE子句中使用这些范围。 动态日期计算 ...

it was supposed to receive -3 too, this is causing a problem in a postgresql driver implementation that receives for example the value microseconds 774702600000000 which is the local time "2024-07-19 11:10:00" from the postgresql driver and when I convert it to DateTime in dart gets wrong...
