데이터베이스의 크기 만 가져 오기 위해 SQL 서버를 어떻게 쿼리 할 수 있습니까?
나는 이것을 사용했다 :
use "MY_DB"
exec sp_spaceused알 겠어 :
database_name database_size unallocated space
My_DB 17899.13 MB 5309.39 MB필요하지 않은 여러 열을 반환합니다.이 저장 프로 시저에서 database_size 열을 선택하는 트릭이 있습니까?
나는 또한이 코드를 시도했다 :
SELECT DB_NAME(database_id) AS DatabaseName,
Name AS Logical_Name,
Physical_Name,
(size * 8) / 1024 SizeMB
FROM sys.master_files
WHERE DB_NAME(database_id) = 'MY_DB'결과는 다음과 같습니다.
DatabaseName Logical_Name Physical_Name SizeMB
MY_DB MY_DB D:\MSSQL\Data\MY_DB.mdf 10613
MY_DB MY_DB_log D:\MSSQL\Data\MY_DB.ldf 7286그래서 나는 이것을 썼다 :
SELECT SUM(SizeMB)
FROM (
SELECT DB_NAME(database_id) AS DatabaseName,
Name AS Logical_Name,
Physical_Name,
(size * 8) / 1024 SizeMB
FROM sys.master_files
WHERE DB_NAME(database_id) = 'MY_DB'
) AS TEMP나는 : 1183
그래서 작동하지만 이것을 얻을 수있는 적절한 방법이 있습니까?

또한 결과를 다음 쿼리의 결과와 비교하십시오.
EXEC sp_helpdb @dbname= 'MSDB'다음과 유사한 결과를 생성합니다
