注：使用的是微軟提供的AdventureWorks2017.bak

1.獲取某表中所有欄位

declare @s nvarchar(4000) = '';
--Object_ID: Schema.Table, Schema預設為dbo
select @s = @s + [name] + ','  FROM sys.columns WHERE Object_ID = Object_ID(N'HumanResources.Department') ;
set @s = left(@s,len(@s)-1);
select @s;

補充：也可以直接將該表下面的列拖動到查詢視窗。

2.獲取所有含某欄位的表

select [name] from AdventureWorks2017.[dbo].sysobjects 
where id in(select id from AdventureWorks2017.[dbo].syscolumns Where name='ModifiedDate')

3.獲取所有表的行數

SELECT a.name, b.rows FROM sys.sysobjects AS a 
INNER JOIN sys.sysindexes AS b ON a.id = b.id
WHERE (b.indid IN (0, 1)) AND (a.type = 'u')
ORDER
 
 BY a.name, b.rows DESC

4.獲取所有儲存過程的建立時間和修改時間。

SELECT name, create_date, modify_date FROM sys.objects
WHERE type = 'P'
ORDER BY modify_date DESC

補充：可以更改type獲取表，檢視等的建立時間和修改時間。

5.獲取資料中所有索引的資訊
