MSSQL 查询数据库总条数和空间使用情况

查询所有表对应的数据量

1.GROUP

SELECT A.NAME AS 表名, MAX(B.ROWS) AS 记录条数
FROM SYS.SYSOBJECTS AS A INNER JOIN SYS.SYSINDEXES AS B ON A.ID = B.ID AND (A.XTYPE = 'U')
GROUP BY A.NAME
ORDER BY 记录条数 DESC

2.FILTER

SELECT A.NAME AS 表名, B. ROWS AS 记录条数
FROM SYS.SYSOBJECTS AS A INNER JOIN SYSINDEXES AS B ON A.ID = B.ID AND (A.TYPE = 'U') AND (B.INDID IN(0, 1))
ORDER BY 记录条数 DESC

查询数据库总条数

SELECT SUM(记录条数) 总条数
FROM (
    SELECT A.NAME AS 表名, B.ROWS AS 记录条数
    FROM SYS.SYSOBJECTS AS A INNER JOIN SYSINDEXES AS B ON A.ID = B.ID AND (A.TYPE = 'U') AND (B.INDID IN(0, 1))
) V

查询空间使用情况

sp_spaceused

-- database_name    数据库大小    保留未使用空间
-- 已使用空间    数据使用空间    索引使用空间    保留未使用空间

Reference：

sp_spaceused (Transact-SQL)
