I would like to extract a file from a database. The file is stored in a BLOB format
Can I extract the BLOB file from the database using an SQL code/command or is there another way in which I can extract the file?
The file is stored as a BLOB but is actually a ZIP file (if that makes any difference)
What is the normal method of extracting a BLOB file?
Hi All,
I am not sure whether this is the right place to post this question. But I am unable to figure out what is the best solution to retrieve and display an image in a html file(stored in varbinary(max) column). I have a list of images in the file and I am supposed to display them. Can anybody please let me know what is the best way to do this?
Thanks a lot!!
Hello,
I had a problem.
I need to transfert tables between from and SQl Server V7 to and Oracle 8I database.
One of my MS-SQL table look like this:
table mySQLtable(
id int,
filetype nvarchar(5),
binaryfile image)
My Oracle destination table is :
table msOracletable(
id number not null,
filetype varchar2(64),
bynaryfile blob)
;
How can I extract datas from my SQL table, specially the binaryfile and
import datas into my Oracle table ?
Can somebody help me ?
I was putting a database together (its a C# application MSSQL) the application will handle a few hundred customers records and save maybe a couple of thousand word docs/images/other doc files wondered if the way to go was blob or filestream, I see the medium and larger databases seem to go for filestream but just wondered as not much mentioned about smaller dbs.I do not think security/disk space/super fast access will be a big issue.

View 5 Replies View RelatedI am required to send an XML file of our clients to head office in Belgium for comparison against a database of known undesirables. The data is in a legacy system with a custom database so I have created an SSIS package that extracts the tables I need into SQL Server and have developed a program that reads from a text source and creates the XML then Secure FTPs it to Hong Kong who will handle it from there.
My problem lies in actually extracting enough data to avoid too many false positives. The scanning will check name, identity (passport number, etc.), town/city and country. We don't hold an identity number and the town/city and country are buried in free format fields. A quick analysis of the 419,000 records shows that the spelling is terribly unreliable, too. In most cases country has not been entered because the clients are local and even when they are overseas, sometimes only the city has been entered. That is often misspelt, too e.g. Kuala Lumpar or Melboure.
The addresses are held in 3 equal length fields called Address_1, Address_2 and Address_3. There's no guarantee that I will find the town/city or country in any particular one of these fields. In some cases, the street number and name are in Address_3 because the first two hold a company name and a C/O line.
So I'm not going to fret over the ones where the address information is nonsense or missing but I would like to try and extract valid country names and town/city names, where present and this is where I get stuck. I'm from a COBOL programming background and although I'm loving getting used to the power of SQL, I'm still a bit stumped when I come across a problem like this probably because I keep thinking of the solution in procedural terms.
I have a feeling that the solution will be to create two separate reference tables, one of towns/cities and the other of countries. I would then somehow search the 3 fields looking for those keywords and if found, entering them in the appropriate part of the output text file to represent town/city and/or country. I did also think about destringing to find the separate words but that doesn't help where the name consists of two words such as NEW ZEALAND.
I would love to hear from anyone who has dealt with a similar problem and has a neat solution to this using SQL.

I am brand new to SQL. Have limited coding experience w/ Visual Basic and database ops w/ Access.
I have come into possession of a SQL 2005 database. The problem is that the designer tried to re-invent the wheel and code a very very poor LMS back end for tracking and reporting. I would like, if possible, to save the database and as far as I am aware - should be able to import into Access and generate statistics and reports to my hearts content.
I have tried w/out success to save the database going through SQL Server Management Studio Express.
Any help or information that could be provided would be appreciated. Any additional information that I can provide, please let me know.
Thanks - Will
I have read access to a database that appears to store files as "BLOBS".I am trying to create a VB macro that extracts the blob file to a location (lets say... my desktop) as an easy way of viewing the content of that file.
I am using Oracle SQL Developer with Read access to the database. The BLOBS can be located but I am unable to find a SQL string that will convert the blobs back into files located on my desktop.I can locate the blob in the database and obviously it appears appears as a text string. I have heard of two keywords: DBMS_LOB and UTL_File.I am not only new to databases but also new to storing files as strings in a database.
We are currently working on a method to store Visio drawings in a SQL Server database. One approach we looked at was to take and store the coordinates of each individual object in the drawing in a table, and then pull those coordinates back out when we need to render the drawing.
The second approach we are examining is the use of BLOB's; specifically, store the entire Visio drawing as a BLOB in SQL Server 7.
We have only been able to find examples utilizing ADO. Is anyone aware of any method to save BLOB's using stored procedures? We'd like to use this method fore simplicity and maintenance sake.
Any hepl would be appreciated.
Thank You.

Hi
I have to populate some datas from sql server database and display it directly in a CSV Format or CSV file. When i run the project it should provide me an option to whether open or save or cancel the file. when i click open it should be opened and be viewed in a excel sheet in CSV format and when i click save it should ask the destination folder and should be saved there in CSV format and when i click cancel it should be cancelled and the application should be closed. pls note that all these actions should happen in the same browser and should not be redirected to anyother page. Can anybody give me the detailed description and code in Asp.Net using C# .It's very Urgent.
RegardsVijay.
Hi,
Can we insert a blob in the database(eg: doc, jpeg, pdf, etc) from the sqlcmd prompt. I want to insert few files into my table having varbinary(max) column and i dont want to use any front end tool for making such insertions. What i am thinking of is providing a file system path for a particular file(eg: doc, jpeg, pdf, etc) to a stored procedure so that it can be inserted into the database, something that we can do via Oracle's sqlldr tool.
Regards
Salil

Hi,
I want to load a file into a blob column using a stored proc. The file will be on a UNC path on the network. Is there a system stored proc or any utility that can be fired off from the sp, using xp_cmdshell that will take a file path from the filesystem and load it into a blob column in a database table.
I have worked with blob fields in the past but in those instances I loaded the blobs into the database from front end ADO.net code. This time around I need to pull this off stricktly from a stored proc.
Any help will be appreciated.
thank you.
All,
I work with Microsoft SQL Server 2005 on windows XP professional.
I'd like to create stored procdure to add image to my database (jpg file).
I managed to do it using VARCHAR variable in stored procedure
and then using EXEC, but it don't work directly.
My Table definiton:
CREATE TABLE [dbo].[Users](
[UserID] [int] IDENTITY(1,1) NOT NULL,
[Login] [char](10),
[Password] [char](20),
[Avatar] [image] NULL,
CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED
(
[UserID] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
My working solution using stored procedure:
ALTER PROCEDURE [dbo].[AddUser]
@Login AS VARCHAR(255),
@Password AS VARCHAR(255),
@AvatarFileLocation AS VARCHAR(255),
@UserId AS INT OUTPUT
AS
BEGIN
SET @Query = 'INSERT INTO USERS ' + CHAR(13)
+ 'SELECT '''+ @Login + ''' AS Login, ' + CHAR(13)
+ '''' + @Password + ''' AS Password,' + CHAR(13)
+ '(SELECT * FROM OPENROWSET(BULK ''' + @AvatarFileLocation + ''', SINGLE_BLOB) AS OBRAZEK)'
EXECUTE (@Query)
SET @UserID = @@IDENTITY
END
I'd like to use statement in the stored procdure:
ALTER PROCEDURE [dbo].[AddUser]
@Login AS VARCHAR(255),
@Password AS VARCHAR(255),
@AvatarFileLocation AS VARCHAR(255),
@UserId AS INT OUTPUT
AS
BEGIN
DECLARE
@Query AS VARCHAR(MAX)
SET @AvatarFileLocation = 'C:hitman1.jpg'
INSERT INTO USERS
SELECT @Login AS Login,
@Password AS Password,
(SELECT * FROM OPENROWSET(BULK @AvatarFileLocation, SINGLE_BLOB) AS OBRAZEK)
SET @UserID = @@IDENTITY
END
It generates error:
Incorrect syntax near '@AvatarFileLocation'.
My question is:
Why it does not work and how to write the stored procedure code to run this code without errors.
Thanks for any reply
I have the file with binary data on my hard disk.
Also I have the table in the database with image field.
I want to load binary data from file to this field. Does any body know how can i do it?
I want to do it using only T-SQL, without any С# (etc.) coding - only sql script is properly.
Hi All,
I am stuck at one place, where I have to convert CSV format file data into SAP IDOC format file. In SSIS we don't have any such SAP adapter (though we have .NET Data Provider for mySAP suite [SSIS SAP Adapter] but this is still not fully supported by Microsoft, plus it doesn't have feature to convert data into IDOC format) that can do this. Can someone here please provide me some pointers on any third party adapters available in market to do this job or if anyone has already developed some custom approach to achieve this task?
Your quick response on this is highly appreciated.

Hi all,
I have a replicated table with a column which is used to store sound files - it is of type varbinary(MAX).
What is the best way to store a file from the filesystem inside this column on the PDA side (i.e. inside SQL Server CE) without loading the whole file into the PDA's memory, i.e. using some sort of buffering?
On full SQL Server 2005 I make use of UPDATE.WRITE() to save buffers inside the column - is there an alternative to this on SQL Server CE? Can anyone provide sample code / point me to samples that deal with SQL Server CE & BLOBs.
Thanks for your help!
Is there a way to extract the zip file and use the textfile within it to transform data.
Please let me know
I keep having the file is corrupt when extracting. I download it many times from MSDN without luck. I just reimage my system with minimum. Please help.
System:
Windows Vista Ultimate 64-Bit
Visual Studio 2008
SQL Server 2005.
A little background on what I am trying to achieve first. We are moving to Azure virtual machines and we will have 8 disks on the SQL Server box. I am adding more files to the primary file group and each file will go on its own drive. I am then rebalancing data across these files by rebuilding all of the indexes on the tables which is working fine. No problems so far all is good.
I now have an additional problem. If there is a lob or blob column on the table, rebuilding the clustered index and all the non clustered indexes doesn't rebalance the blob or lob data across the disks such as it does with in row data.
I cannot find any articles on rebalancing lob or blob data because all the articles say to move to a new file group. I do not want a new file group, I just want to use the primary file group where the data already resides, and just redistribute it evenly in the same way that I can in row data which is working fine.
One solution I thought about was to BCP data out of the table, truncate the table and then BCP back into the table which I imagine would have the desired effect of distributing the data evenly over the files.
My goal is to write a DR plan where i am restoring all user databases onto a diffrent server in a event of hardware failure. I was trying to figure out a way to extract DDL of user accounts and their permissions on all user databases so i can simplify my DR documentation.
This is the plan I came up with...to restore all system and user dbs on a different Physical SQLServer.
1. build named instance $PROD
2. restore master database
- startup sqlserver in single user mode -m or DAC sqlcmd -S ServerName -U sa -P<xxx> –A
net stop MSSQLSERVER$PROD
net start MSSQLSERVER$PROD -m
- restore database master from disk e:master.bak with replace;
3. start sqlserver normally
4. stop SQLServer agent
5. restore msdb
-restore database msdb disk e:msdb.bak with replace;
6. restart SQLServer
7. Restore User Databases.
8. Run Sp_change_users_login for all users
-Sp_Change_users_logins 'auto_fix','username'
Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.

Hi,
I have a dataflow task which has 3 oledb source objects connected to each data conversion object and these are connected to a union all and finally to a flat file destination.
The purpose of this one is to extract data and pump them to the flat file.
If i run this in production during the time users are doing transactional processes (typical, add, edit delete), will it have an impact?
