sql-server - 表使用的空间

Question

此过程是否准确显示数据库中使用的空间？我怀疑结果。

DECLARE @TableName VARCHAR(100)    --For storing values in the cursor

--Cursor to get the name of all user tables from the sysobjects listing
DECLARE tableCursor CURSOR
FOR 
select [name]
from dbo.sysobjects 
where  OBJECTPROPERTY(id, N'IsUserTable') = 1
FOR READ ONLY

--A procedure level temp table to store the results
CREATE TABLE #TempTable
(
    tableName varchar(100),
    numberofRows varchar(100),
    reservedSize varchar(50),
    dataSize varchar(50),
    indexSize varchar(50),
    unusedSize varchar(50)
)

--Open the cursor
OPEN tableCursor

--Get the first table name from the cursor
FETCH NEXT FROM tableCursor INTO @TableName

--Loop until the cursor was not able to fetch
WHILE (@@Fetch_Status >= 0)
BEGIN
    --Dump the results of the sp_spaceused query to the temp table
    INSERT  #TempTable
        EXEC sp_spaceused @TableName

    --Get the next table name
    FETCH NEXT FROM tableCursor INTO @TableName
END

--Get rid of the cursor
CLOSE tableCursor
DEALLOCATE tableCursor

--Select all records so we can use the reults
SELECT * 
FROM #TempTable order BY tablename

--Final cleanup!
DROP TABLE #TempTable

对这篇文章的格式感到抱歉。 StackO 确实有问题 - 今天没有格式化工具栏。

您的代码给出了所用空间的逐 TableView 。您也可以只运行不带参数的 sp_spaceused 来了解整个数据库的大小。是什么让您怀疑结果？
