I want to store images in a sql database. The size of the image is between 50kb to 1mb. I was reading about a FileStream and a FileTable but I don't know which to choose. Each row will have 2 images and some other fields.
The images will never be updated/deleted and about 3000 rows will be inserted a day.
Which is recommend in this situation?
Originally it was always a bad idea to store files (= binary data) in a database. The usual workaround is to store the filepath in the database and ensure that a file actually exists at that path. It wás possible to store files in the database though, with the varbinary(MAX) data type.
sqlfilestream was introduced in sql-server-2008 and handles the varbinary column by not storing the data in the database files (only a pointer), but in a different file on the filesystem, dramatically improving the performance.
filetable was introduced with sql-server-2012 and is an enhancement over filestream, because it provides metadata directly to SQL and it allows access to the files outside of SQL (you can browse to the files).
Advice: Definitely leverage FileStream, and it might not be a bad idea to use FileTable as well.
