What is the difference between text and Ntext in SQL?
Unicode (ntext) has the capability to store characters from all languages, while text typically uses a local code page and can only use local characters. SQL Server uses 2 bytes per character for n-type text columns, while the not-n-type columns use 1 (at least for latin-based languages).
Is Ntext deprecated SQL Server?
ntext, text, and image data types will be removed in a future version of SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.
When might you use Ntext instead of Nvarchar?
ntext will always store its data in a separate database page, while nvarchar(max) will try to store the data within the database record itself. So nvarchar(max) is somewhat faster (if you have text that is smaller as 8 kB). I also noticed that the database size will grow slightly slower, this is also good.
What is the difference between VARCHAR and text in SQL Server?

What is difference between VARCHAR CHAR and TEXT?

Should I use Nchar or NVARCHAR?
When to use what? If your column will store a fixed-length Unicode characters like French, Arabic and so on characters then go for NCHAR. If the data stored in a column is Unicode and can vary in length, then go for NVARCHAR. Querying to NCHAR or NVARCHAR is a bit slower then CHAR or VARCHAR.
