How to get paragraph size data from sql server database?

If you want to store large amounts of text in a SQL database, then you want to use either a varchar(max) or a nvarchar(max) column to store that data. In case you don't know the difference, nvarchar will support Unicode characters. If you aren't sure if you will need Unicode support, that means you probably will so use nvarchar. If you know for absolute certainty that you won't need it then use varchar (uses half the space). These column types work like any other column in how you read and write to them. The only difference is that if the data gets too large, SQL will store it on disk outside the normal storage. That will make the retrieval process take longer.
 
I would recommend you look into these options and carefully think through what is best for your situation.
