Upload multiple files to SQL Server Image column

December 14, 2004

This article examines how to upload multiple files to a SQL Server table. There are many ways to do this. The method I would like to introduce takes advantage of the OSQL.exe utility and the TEXTCOPY.exe utility.

Pre-requisite

1. SQL Server 2000 client is installed on the machine where you are running this batch file
2. SQL Login used has at least DBO permission on the database

Step 1

Create C:\Upload folder

Step 2

Copy TextCopy.exe from \Program Files\Microsoft SQL Server\MSSQL\Binn to C:\Upload folder [Ref Fig 1.0]

Step 3

Copy and paste the code below into C:\Upload\Upload.bat

@ECHO off
cls
REM ECHO on
REM Objective: To upload all the files in the folder to SQL server as a table
REM Created by: MAK
REM Date: Nov 3, 2004
REM Contact: mak_999@yahoo.com
REM Check parameters
if "%1"=="" Goto noparmErr
if "%1"=="/?" Goto Help

REM assign variables
set Sourcefolder=%1
set servername=%2
set Databasename=%3
set loginname=%4
set password=%5
set LogFile=%6

Date/t > %6
time /t >> %6

REM Export DIR listing to C:\upload\Dirlist.txt
dir %1 /b > C:\upload\Dirlist.txt

OSQL /S%2 /U%4 /P%5 /d%3 /Q"if exists (select * from %3.dbo.sysobjects where id =
 object_id(N'[Myuploadtable]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) drop table
 %3.dbo.[Myuploadtable] " >> %6

OSQL /S%2 /U%4 /P%5 /d%3 /Q"create table %3.dbo.Myuploadtable (id varchar(500), 
 ImageFiles Image)" >> %6

FOR /F "usebackq delims==" %%i in (C:\upload\Dirlist.txt) 
  do OSQL /S%2 /U%4 /P%5 /Q"insert into %3.dbo.Myuploadtable (id,ImageFiles) 
  values('%%i',' ') " >> %6


FOR /F "usebackq delims==" %%i in (C:\upload\Dirlist.txt) 
  do c:\upload\textcopy.exe /S%2 /U%4 /P%5 /D%3 /Tmyuploadtable /CImagefiles 
    /F"%1%%i" /I /W"where [id]='%%i'" >> %6

GOTo END2

Download upload.bat

Step 4

Execute the batch file. [Ref Fig 1.1]

[Fig 1.1]

Step 5

Execute the batch file with the correct parameters [Ref Fig 1.2]. When executed with the correct parameters, this batch file calls the OSQL utility and creates [Myuploadtable] on the given database. Then, using the same OSQL utility it inserts rows into the table. The number of rows and the number of source files will be same, the values in the column is the same as the name of the files in the folder [Ref Fig 1.4, 1.5. Then it calls the TEXTCOPY utility and uploads every file in the source folder [Ref Fig 1.3] to the SQL server table.

[Fig 1.2]

Parameters Explained

[Fig 1.3]

Select ID from Myuploadtable.

select * from Myuploadtable

Step 6

Rename the table.

sp_rename 'Myuploadtable','Prod_ImageTable'

When you run the batch file again, it will drop and recreate the [Myuploadtable] table. That is why we are renaming the table.

The batch file also creates a log file as shown below.

Conclusion

As mentioned earlier, the intent of this article has been to guide SQL Server developers and administrators in uploading multiple files to a SQL Server table.
