Binary Data Storage In SQLServer

With the advances of digital communication and big data, binary data storage in data bases become more and more important. SQLServer is a popular commercial relational database, which provides a range of data types to store binary data. In this article, I will discuss how to store binary data in SQLServer.

SQLServer provides several data types for storing binary data. Depending on the size of the binary data, the data type can be selected either as varbinary, image or varbinary(max). Varbinary is designed to store up to 8000 bytes of data while image is designed to store up to 2 GB of data. Varbinary(max) is the latest data type designed to store data up to 2^64 – 1 bytes.

To store binary data in SQLServer, the following steps can be followed. Firstly, create a table in SQLServer with a column of type varbinary or image. The data type should be selected depending on the size of the binary data. Secondly, use the following T-SQl command to store the binary data.

INSERT INTO File_name
VALUES(@data)

Here @data is the binary data stored as a parameter of the SQLServer command. This command can be used in a loop if binary data from a list of files need to be inserted in the table. Finally, the binary data is retrievable from the table with the following T-SQl command:

SELECT data
FROM file_name

It is important to note that the binary data should be prepared in the right format if we want to store it in SQLServer. For example, when we convert a file to a binary stream, we need to ensure the encoding format to be the same as the one used by the server.

In conclusion, with the help of our discussion, we now understand how to store binary data in SQLServer. This also helps us to better understand the data types that SQLServer provides and the commands that can be used to manipulate the binary data stored in the database table.
