filegrowth=1
)
log on(
name=testdb_log,
filename='d:	estdb_log.ldf',
size=1,
maxsize=unlimited,
filegrowth=10%
)

查看数据库信息

execute sp_helpdb testdb1

或 sp_helpdb

sp_helpdb testdb1

alter  database testdb1
add file(
name=testdb1ndf1,
filename='d:	estdb1ndf1.ndf',
size=5mb,
maxsize=10mb,
filegrowth=6mb
) to filegroup mygroup

alter database testdb1
add log file(
name=testdb3_log,
filename='d:	estdb3.ldf',
size=5mb,
maxsize=10mb,
filegrowth=10%
)

alter database testdb1
modify file(name=testdb1,size=21mb)
go
alter database testdb1
modify file (name=testdb_log,size=21mb) 

alter database testdb1
add filegroup mygroup
go

sp_helpfilegroup

设置数据库只可以读

属性→选项→状态→数据库只读 true

use test
go
alter database test set read_only -- read_write
go

--sp_dboption test, 'read only','false'

sp_helpdb test

use test
go
alter database test set read_write
go

alter database test
modify file(name=te,size=15mb)

use test
go 
dbcc shrinkfile(te,10)
go

任务→收缩→数据库

选中数据库→重命名→要改数据库名字→回车

sp_renamedb 原数据库名，新数据库名

drop database test
