如何高效进行SQL Server数据库巡检？
摘要：查询所有表名 select name from sysobjects where xtype='u' select * from sys.tables 查询所有表名及对应架构 select t
查询所有表名
select name from sysobjects where xtype='u'
select * from sys.tables
查询所有表名及对应架构
select t.[name] as tablename, s.[name] as [schema] from sys.tables as t,sys.schemas as s where t.schema_id = s.schema_id
查询数据库中所有的表名及行数
SELECT a.name, b.rows
FROM sysobjects AS a INNER JOIN sysindexes AS b ON a.id = b.id
WHERE (a.type = 'u') AND (b.indid IN (0, 1))
ORDER BY b.rows DESC
查询所有的表及空间占用量\行数
select
object_name(id) tablename,
8*reserved/1024 reserved,
rtrim(8*dpages)+'kb' used,
8*(reserved-dpages)/1024 unused,
8*dpages/1024-rows/1024*minlen/1024 free,
rows--,*
from sysindexes
where indid=1
order by tablename,reserved desc
查询数据库中所有表名及行数 --带架构名
SELECT s.name,a.name, b.rows
FROM sys.tables AS a
INNER JOIN sysindexes AS b ON a.object_id = b.id
LEFT JOIN sys.schemas as s on a.schema_id = s.schema_id
WHERE (a.type = 'u') AND (b.indid IN (0, 1))
ORDER BY b.rows DESC
数据库文件信息
SELECT a.name [文件名称]
,a.type_desc AS [文件类型]
,cast(a.[size]*1.0/128 as decimal(12,1)) AS [文件设置大小(MB)]
,CAST( fileproperty(s.name,'SpaceUsed')/(8*16.0) AS DECIMAL(12,1)) AS [文件所占空间(MB)]
,CAST( (fileproperty(s.name,'SpaceUsed')/(8*16.0))/(s.size/(8*16.0))*100.0 AS DECIMAL(12,1)) AS [所占空间率%]
,CASE WHEN A.growth =0 THEN '文件大小固定，不会增长' ELSE '文件将自动增长' end [增长模式]
,CASE WHEN A.growth > 0 AND is_percent_growth = 0 THEN '增量为固定大小'
WHEN A.growth > 0 AND is_percent_growth = 1 THEN '增量将用整数百分比表示'
ELSE '文件大小固定，不会增长' END AS [增量模式]
,CASE WHEN A.growth > 0 AND is_percent_growth = 0 THEN cast(cast(a.growth*1.0/128as decimal(12,0)) AS VARCHAR)+'MB'
WHEN A.growth > 0 AND is_percent_growth = 1 THEN cast(cast(a.growth AS decimal(12,0)) AS VARCHAR)+'%'
ELSE '文件大小固定，不会增长' end AS [增长值(%或MB)]
, CASE WHEN a.max_size=-1 then -1 ELSE cast(a.[max_size]*1.0/128 as decimal(12,1)) end as [文件增长最大大小(MB)]
,a.physical_name AS [文件所在目录]
FROM sys.database_files a
INNER JOIN sys.sysfiles AS s ON a.[file_id]=s.fileid
LEFT JOIN sys.dm_db
