Using C# with SQL Server Express/Standard

Posted on 2009-04-10

I'm building a program in C# with a local database backend.  I was going to try to use MS SQL Server Express.  However I need to store binary files in the database and the byte limit of Server Express is 8000 bytes.  I was wondering if the standard edition would allow me to store files around 100 KB in size to binary fields.  And if so can I use the Standard edition to deploy with my program as a local database.

To store binary files You should use BLOB type. In SQL server it's called varbinary(max). There is no type difference between Express and Standard SQL Server.

Is it just a limitation of the GUI tool that came with the engine?  varbinary is there but it won't let me put a size larger than 8000 bytes.

Okay so in the designer I can make a varbinary(max) field but in the import tool, I'm trying to import from a mediumblob in a mysql database to this MS SQL database.  Maybe I'll just have to reimport the data?  It just won't let me put varbinary(max) as the destination type using the import.

If You have problem with import wizard, You should try workaround.
Try varchar(MAX) instead of varbinary(MAX).
or
You can try to transfer binary files other way than Import Wizard. With c# program or similar like this:

As a workaround consider importing temporarily into an Image column and then copying from there to a varbinary(MAX)
