检查文件内容 SQL Server 2008 R2

Question

我们有一个接口，每天创建三个文件，名称格式如下：

FileAYYYYMMDD（示例：FileA20170925）
FileBYYYYMMDD（示例：FileB20170925）
FileCYYYYMMDD（示例：FileC20170925）

需要有人手动检查这些文件是否为空。我想自动执行此步骤。

我想知道的：有没有办法通过 SQL 查询或 SQL 作业来确定这些文件是否为空（是或否就足够了）？

Answer 1

根据 MatSnow 的建议，我能够 find/create spFileDetails 存储过程。使用这个存储过程，我能够创建 SSRS 报告，这将帮助我自动化该过程。此外，我什至可以通过传递日期参数来评估历史文件：

declare @FileDATE AS VARCHAR(8) 
select @FileDATE = (SELECT CONVERT(VARCHAR(10), @ReportDate, 112))

DECLARE @FolderLocation as varchar(200) 
select @FolderLocation =  ( '\share\Validation\File' + @FileDATE + '.txt')

DECLARE @FolderLocationA as varchar(200) 
select @FolderLocationA = ( '\share\Validation\FileA' + @FileDATE + '.txt')

DECLARE @FolderLocationB as varchar(200) 
select @FolderLocationB = ( '\share\Validation\FileB' + @FileDATE + '.txt')


DECLARE @TempTable Table(
[Path] varchar(300),    
ShortPath   varchar(300),
[Type]  varchar(20),
DateCreated  date,
DateLastAccessed date,  
DateLastModified    date,
Attributes  int , 
size int)

INSERT INTO @TempTable
Execute dba.dbo.uspGetFileDetails  @FolderLocation
INSERT INTO @TempTable
Execute dba.dbo.uspGetFileDetails  @FolderLocationA
INSERT INTO @TempTable
Execute dba.dbo.uspGetFileDetails  @FolderLocationB

Select * from @TempTable

您应该能够使用存储过程 spFileDetails 从此 site.

获取文件大小

如果文件大小为 0，则文件为空。这是存储过程的副本。感谢"Phil Factor"
