查詢Sql Server數據庫對象結構

1. 查詢數據庫
2. 查詢架構
3. 查詢表
4. 查詢列
5. 查詢存儲過程
6. 查詢視圖

---

1.查詢某一服務器下所有數據庫

select t.[name] as 數據庫
from sys.databases as t
order by name

2.查詢某一數據庫的架構

select name as 架構,
	schema_id as 架構Id
	--,principal_id
from sys.schemas
where principal_id = 1;

3.查詢某一數據庫的表

select s.name+'.'+t.name as 表,
	t.object_id as 表Id
from sys.tables as t
inner join sys.schemas as s on t.schema_id = s.schema_id and s.principal_id=1 	

4.查詢某一數據庫的所有的列

select
	s.name as 架構,
	d.NAME as 表,
	A.NAME as 列,
	COLUMNPROPERTY( a.id,a.name,'IsIdentity') as 是否為自增, --0非自增 1自增
	B.NAME AS 數據類型,
	COLUMNPROPERTY(A.ID,A.NAME,'PRECISION') AS 精度,
	ISNULL(COLUMNPROPERTY(A.ID,A.NAME,'Scale'),0) AS 保留位,
	A.ISNULLABLE AS 是否為空, -- 0空 1非空,
	ISNULL(E.TEXT,'') as 默認值,
	ISNULL(g.[value],'') AS 列說明
FROM syscolumns a  
LEFT JOIN systypes b ON a.xtype=b.xusertype
INNER JOIN sys.objects d ON  a.id=d.object_id AND d.type='U'AND d.name<>'dtproperties' 
inner join sys.schemas as s on d.schema_id=s.schema_id
LEFT JOIN syscomments e ON a.cdefault=e.id 
LEFT JOIN sys.extended_properties g ON a.id=g.major_id AND a.colid=g.minor_id 
LEFT JOIN sys.extended_properties f ON d.object_id=f.major_id AND f.minor_id =0

5.查詢存儲過程

select 
	s.Name as 架構,
	p.Name as 存儲過程,
	sm.definition as 存儲過程內容		 
from sys.procedures as  p
inner join sys.sql_modules sm ON p.object_id = sm.object_id
inner join sys.schemas as s on p.schema_id=s.schema_id

6.查詢視圖

select 
	s.name+'.'+t.name as 視圖,
	t.object_id as 視圖Id
from sys.views as t
inner join sys.schemas as s on t.schema_id = s.schema_id and s.principal_id=1
