Sql server Sql Server文件流总文件大小

是否有查询可以获取磁盘上FILESTREAM文件夹中文件的总文件大小？

以下查询将返回FILESTREAM列的长度（以字节为单位）：

Remus解决方案的一个缺点是，它不包括可用于垃圾收集的文件的旧版本。它们将不再是逻辑数据库的一部分，但仍将占用磁盘空间，直到Filestream垃圾收集器删除它们

从Sql Server 2008 R2开始，您可以查询sys.database_文件的size列，以获得给定filestream容器使用的大致大小，即磁盘空间

use <DATABASE_NAME_HERE>
declare @table as nvarchar(100);
declare @columnName as nvarchar(100);
declare @query as nvarchar(500);
declare @sizeValue as nvarchar(100);
declare @generalValue as decimal(38);
declare @generalValueInMb as decimal(15,2);
set @generalValue = 0;

DECLARE tableCursor CURSOR FOR
(
SELECT DB_NAME()+'.**<schemaname_here>**.' + OBJECT_NAME(object_id) AS [FullTableName], name As [ColumnName]
FROM sys.columns
WHERE is_filestream = 1 
)

Open tableCursor

fetch next from tableCursor into @table, @columnName

while @@FETCH_STATUS = 0
begin
set @query = 'select @sizeValue = (select sum(Datalength('+@columnName+')) FROM ' + @table +')';
exec sp_executesql @query, N'@sizeValue int output', @sizeValue output;

if @sizeValue is not NULL
begin
set @generalValue = @generalValue + @sizeValue
end

fetch next from tableCursor into @table, @columnName
end

close tableCursor
deallocate tableCursor

select @generalValueInMb = round(@generalValue / 1024 / 1024, 2)

select @generalValueInMb

请注意，您需要在上述代码的适当位置键入架构名称。

我正在运行SQL 2008 R2 SP0 CU8，filestream的size列始终为0。

use <DATABASE_NAME_HERE>
declare @table as nvarchar(100);
declare @columnName as nvarchar(100);
declare @query as nvarchar(500);
declare @sizeValue as nvarchar(100);
declare @generalValue as decimal(38);
declare @generalValueInMb as decimal(15,2);
set @generalValue = 0;

DECLARE tableCursor CURSOR FOR
(
SELECT DB_NAME()+'.**<schemaname_here>**.' + OBJECT_NAME(object_id) AS [FullTableName], name As [ColumnName]
FROM sys.columns
WHERE is_filestream = 1 
)

Open tableCursor

fetch next from tableCursor into @table, @columnName

while @@FETCH_STATUS = 0
begin
set @query = 'select @sizeValue = (select sum(Datalength('+@columnName+')) FROM ' + @table +')';
exec sp_executesql @query, N'@sizeValue int output', @sizeValue output;

if @sizeValue is not NULL
begin
set @generalValue = @generalValue + @sizeValue
end

fetch next from tableCursor into @table, @columnName
end

close tableCursor
deallocate tableCursor

select @generalValueInMb = round(@generalValue / 1024 / 1024, 2)

select @generalValueInMb
