How to avoid ntext text and image in SQL Server?

How to download SQL Server Base64 in image format?
You can then leverage SQL Server Data Tools (SSDT) to loop and download all the decoded Base64 content to the file system in image format. In this tip, we will run through the actual mechanics to the solution using XQuery and SSDT.
Where is Base64 encoded data stored in SQL Server?
Solution. Base64 encoding schemes are commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data. From this definition, we would expect the Base64 content is stored in a VARCHAR(max) data type in SQL Server.
