Hi RichardSa,
Refer below sample.
Database
CREATE TABLE [dbo].[tblFiles](
[id] [int] IDENTITY(1,1) NOT NULL,
[Name] [varchar](50) NOT NULL,
[ContentType] [nvarchar](200) NOT NULL,
[Data] [varbinary](max) NULL,
CONSTRAINT [PK_tblFiles] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
I have inserted few record in the table.
For more details on insert refer below article.
