Hi Rolleiv, 

You can try SqlExecutor.ExecuteAsync to execute a SQL UPDATE statement to update byte[] to the database table.

E.g.:

        public async Task<int> UpdateProductPhotoAsync(int productPhotoId, byte[] photo)
        {
            string sql = "UPDATE Production.ProductPhoto SET LargePhoto = :phote WHERE ProductPhotoID = :productPhotoId";
            
            return await _context.SqlExecutor.ExecuteAsync(sql, photo, productPhotoId);
        }

Regards,

Logan

Hi Rolleiv,

If what you want is to to add an update function to a table that includes a blob column, then whether you use SnapDevelop or not, is irrelevant. What matters is the framework you're using for the REST API allows you to do so (which it most likely does) and whether or not you know how to do this. SnapDevelop is just the IDE.
