Hi,
How do I create a large column type in MSSQL similar to the Blob field in MySql.
I trying to upload data to mssql but keep on receiving the error tat the columns buffer size is not big enough ?
I've tried using varchar with size 8000, but stil NOT working
Any ideas ????
Thanks
Hi all!
I'm trying importing a MySQL database to my MSSQL server. I've donwloaded the MySQL ODBC drivers and I can connect succesfully throught a DSN to my MySQL server. Everything works fine EXEPT my BLOB field. I'm using a BLOB field for storing a binary file.
When I choose preview while importing my bob field is empty.
I'm desperate!
:eek:
Does anyone have any experience of this type of data please? I have been asked to work on a project where it looks like we will be taking MS Office files and scanned images and storing them in a SQL 2000 db so that they can be aquired by a third party application. I am most intereested in the size of the records as the server may need upgrading, for space and performance.
I am also interested in how a BLOB record is created, is it a particular save process from Word / Excel etc or can you specify to import as a BLOB from a SQL script?
Any info welcomed as i really dont know where to start !!!
TIA
I have a column in my table that is an Image (blob). The data storedin this blob is basically pdf files. I need a query to determine thetotal size of these blob's in the database. Here is what ishappening, if I run it as below I get 23736000 for a result.select sum(datalength (cast(document AS binary(8000)))) fromplan_reportIf I run it like this select sum(datalength (cast(document ASvarbinary(8000)))) from plan_reportI get 23736000 also as a resultIf I run it like this select sum(datalength (cast(document ASvarbinary))) from plan_reportI get 89010 this as a resultIf I run this: select datalength(document) from plan_report then Iget a result for each row and when I sum those rows I get 5584452854this as a result.I do not believe the first 3 queries are returning correct result setsdue to the limit on the fields (binary/varbinary) and since this is animage field I cannot convert to anything else.....I am out of ideas, and any help you can give me will be greatlyappreciated...

I am trying to store binary datafiles into a SQl Express table. However I can not find the BLOB data type when I am designing the table. Are we limited to using that kind of data type in the Express edition? Thanks.

I am using SqlServer 2000 and Jdbc connectivity in my application on windows.So, when i execute a query on Sqlserver database as :
Select * from DBO.RS_TABLELOB where Rep_sync_id > 15 and Rep_server_name != 'replicator' order by Rep_sync_id;
This problem is only with the BLOB data types in table RS_TABLELOB.
Then i got an error as:

Hi! I tried to save some image data, but it get truncated at 8000 (the table column is defined as Image). I then wrote a converter to try ntext-datatype instead, but it gets truncated at 4000.
Error message:
System.Data.SqlServerCe: @3 : String truncation: max=4000, len=4168
The code uses only ADO entity framework for database access. Is there a way to store binary data larger than 8000 bytes? I am running SQL Compact 3.5 sp 1 BETA.

Hello, I cannot find out to create enum data type in SQL Server 2005 Express. Can I easily create the enum type just like the MySQL does.(please the MySQL example below)
CREATE TABLE myTable
(
myid INT UNSIGNED NOT NULL,
myclass ENUM('FIRST','SECOND','THIRD') DEFAULT 'FIRST'
PRIMARY KEY(myid)
);
I am having a problem with MMSQL BLOB with VB, Sorry to say I am new in Programming using VB 6 and MSSQL and I have never touch BLOB in my live.
I just wish anyone could give me any ideal, like, white pages, or manual on how do I insert BLOB data (Images) to MSSQL 2000 database using VB 6. I need to know exspecially the VB Code and the SQL Portion if you have a store procedure code for that it will be nice.
:confused:
We are debating what is industry “best practice� for serving huge numbers of images in an industrial scale website. More directly, which approach produces the best performance and the best scalability? For example, how do sites like ebay, Amazon, and other large sites handle the millions or billions of images they must deal with?
Store as BLOB in sql server?
Store in /images folder and store url text into sql server?
We always assumed that the second approach is what most sites must do. But do they?
One developer on our team maintains that storing one million or more image files in a directory will most certainly result in poor performance, because the server must scan the directory, searching for the correct file, each time a web request is made. The directory is not indexed (?) so performance must eventually suffer.
Other developer counters that storing millions of images as BLOBs into sql server will result in poor performance and HUGE database. An additional layer of access (webserver to sql server, back to webserver, then to client) causes a delay and performance hit.
Who is right? What do the gurus as the world class sites do?

I have an internal Project Management and Scheduling app that I wrote internally for my company. It was written to use MySQL running on a Debian server, but I am going to move it to SQL Server 2000 and integrate it with our Accounting software. The part I am having trouble with is the user login portion. I previously used this:
PHP Code:
$sql = "SELECT * FROM users WHERE username = "$username" AND user_password = password("$password")";
Apparently the password() function is not available when accessing SQL Server via ODBC. Is there an equivalent function I could use isntead so the passwords arent plaintext in the database? I only have 15 people using the system so a blank pwd reset wouldn't be too much trouble.
I have had an application running successfully in production for two years. In the last three months the app has become a document management system as well. During the addition of images, it was decided that no images would be stored in the database but on the file system. We now have over 500,000 images averaging in size of 92k each. I had to upgraid the raid once and I can only assume that I will again. I am not expecting the image count to exceed 700,000 in the next 6 months; By this time next year, I am expecting 1.2 million.
Should I reconsider storing the images in the database?
If they are stored in the database, what are the effects on performance?
Thanks in Advance

Does sql server has the data type similar to BLOB (Binary largerobject)which is available to DB2. BLOB in DB2 can support up to 2 G(variable-length data )if it does have, which one offers better functionalitiesany advice will be greatly appreciated!
View 4 Replies View RelatedHi,One of our third-party software vendors is planning to implement BLOBin their database for storing certain documents. We are not toothrilled about it, since it can be a drain on our resources, but Iwould like to get the expert opinion out there on the pros and cons ofimplementing this.Also, the database is in Full recovery mode and we back up thetransaction log every 15 minutes. We also do a process similar to logshipping. We have two servers to which these transaction logs arerestored to periodically. What will the impact on the transaction logsdue to changes to the BLOB fields.If you could also point me to any resources that talks in detail aboutperformance, backup and recovery in relation to BLOB that would begreat.Thanks in advanceKR
View 3 Replies View RelatedHi,
can anyone help ,me out here with some design consideration reguarding importing of BLOB data to a SQL server 2000 using T-SQL statements?
I want to make an import of some documents which are stored in a Access database, to an Ms SQL server 2000. The documents are stored in the access database as a OLE Object, by now I thought of using the base64String function to convert the data from the access field and write it to the T-SQL statements which will written in a text batch file. And then I apply the SQL Convert function something like:
INSERT INTO testBin VALUES(convert(image,'base64sting_encoded'))
go
Does this work? Is it correct what I am doing?
Thanks.

I'm trying to transfer a table from a sql 7 server to an sql 6.5 server. When I try to select OLE db as the destination it gives me an error saying I can't do OLE DB unless I have sql 7.... So I chose ODBC
When it tries to transfer the table I get this error:
QUERY BASED INSERTION OR UPDATING OF BLOB VALUES CAN NOT BE SUPPORTED
what the hell? Is this due to the transfer from 7 to 6.5? How do I get around this?
-----
What I'm trying to do is change the datatype of a table in this 6.5 database from smallint to integer... (I wasn't the idiot that designed this database with a smallint primary key) There is not enough room to copy the table into a new table, and when I ran through the above process it dropped the table and I can't restore it because I'm not the admin. Is there a way of changing the primary key datatype without using up a large amount of database space? or can I do a transfer from 7-6.5 some how?
This is a nightmare... I wish my client would just upgrade to 7 then this would have taken 5 seconds instead of all day long
Hi,
I know in Mysql one can use a blob field(instead of varchar) to insert big amounts of data into a field - e.g User Notes or Long detailed descriptions
How do I create a field using Enterprise Manager(MSSQL) to be able to handle this amounts of data ???
I can't seem to find the BLOB-option upon creating a field in MSSQL, am I missing something here ???
Many thanks
Hello,
I currently have a problem with blobs being cut off.
From powerbuilder, I am trying to pull in an image that is stored as a blob. This has always worked fine in our software, until a more recent version, and is now presenting me with this problem. Here are the details...
When the software is installed with a Sybase Database, everything is working great. It pulls in the full size, and there are no problems here.
However, when the software is installed with a SQL Server DB, problems arise.
The main problem: When using a ADO.NET DBMS interface to the SQL Server DB, the select statement is only pulling in 32000 bytes.
Secondary problem: This one may present a problem in the future, if and when i fix the first problem. To narrow it down to see if it was the ADO.NET interface giving me the problem, i connected to the same table on the same server, but using an ODBC interface as opposed to ADO.NET. This gave me the first 32768 bytes.
So a) ADO.NET when interfacing with SQL Server is only giving me the first 32000 bytes in my selectblob statement. I have narrowed it down to ADO.NET, as the code works fine with Sybase, and ODBC interfacing with SQL Server does not limit it at 32000 bytes.
and if I get a solution to that, something may then be limiting the blob read in size at 32768. Maybe, maybe not... but it is happening with ODBC|SQL Server.
Does anyone have any ideas. This is driving me wild. I have pounded google searching for ADO.NET known blob limitations but cannot find anything.
I'm dying here. Anyone who can help me out would be great. Thanks

Hi,
I have a conversion application which convertts an access database to an sql server(different versions). I'm using stored procedures. The thins is that I export the OLe Object form access to SQL varbinary. what I do is to convert the binary data from the OLE Object to string using ToBase64String. The thing is that when I execute the SQL statement I get the following error:
Error:Operand type clash: text is incompatible with varbinary.
Can anyone tell me what I do wrong and how can I fix this? Thanks.

I'm trying to retrieve an image that I have stored in a SQL Server db, and display it in an .aspx page. It's supposed to retrieve just one image, according to a unique key that's passed. However, when I view the page, nothing appears... just the Internet Explorer missing image placeholder.
I've tried code from several diff tutorials, and can't seem to get it to work.
I'm aware that some people think it's not a good idea to store images in a db, but I have to in this case, since the requirements for this project are that the images are stored in the database. I already know how to store references to file paths of images located in a server folder. I've just never done it this way... storing the whole images in the database. The table has 3 columns, one for the id, "FileType" stores the image type, and the "ImageBinary" is the image itself.
If anyone can shine some light on why my code doesn't display anything, I'd greatly appreciated your help.
