要求该存储过程返回database_name ,database_size ,unallocated space 这三个值
declare @dbname sysname
declare @dbsize dec(15,0)
declare @logsize dec(15)
declare @bytesperpage dec(15,0)
declare @pagesperMB dec(15,0)
select @dbsize = sum(convert(dec(15),size))
from dbo.sysfiles
where (status & 64 = 0)
select @logsize = sum(convert(dec(15),size))
from dbo.sysfiles
where (status & 64 <> 0)
select @bytesperpage = low
from master.dbo.spt_values
where number = 1
and type = E
select @pagesperMB = 1048576 / @bytesperpage
select database_name = db_name(),
database_size =
ltrim(str((@dbsize + @logsize) / @pagesperMB,15,2) + MB),
unallocated space =
ltrim(str((@dbsize -
(select sum(convert(dec(15),reserved))
from sysindexes
where indid in (0, 1, 255)
)) / @pagesperMB,15,2)+ MB)
print
参数后带output就行
