使用GETDATE() +或-来计算附近的日期

SELECT GETDATE() - 1 -- yesterday, 1 day ago, 24 hours ago
SELECT GETDATE() - .5 -- 12 hours ago
SELECT GETDATE() - .25 -- 6 hours ago
SELECT GETDATE() - (1 / 24.0) -- 1 hour ago (implicit decimal result after division)

您可以用一个插入语句插入多行数据。

INSERT INTO Colors (id, Color)
VALUES (1, 'Red'),
       (2, 'Blue'),
       (3, 'Green'),
       (4, 'Yellow')

下面是一些我喜欢的SQL Management Studio隐藏特性。

我喜欢的一点是，如果你在高亮显示信息时按住ALT键，你可以选择柱状信息，而不仅仅是整行。

在SQL Management Studio中，你有预定义的快捷键:

Ctrl+1运行sp_who Ctrl+2运行sp_lock Alt+F1运行sp_help Ctrl+F1运行sp_helptext

因此，如果您在编辑器中突出显示表名并按Alt+F1，它将显示表的结构。
