Hi,

You can use the NVARCHAR data type to store the special characters. While inserting the data into the database table you need to Use the following format. "N'your data here'".

In the above example you can see only a prefix "N" before your data. This will allow you to save the special characters into the database table.

You can use Var-char/text datatype to store this type of characters in sqlDB.
i think you are decoding the output when fetching from database using HtmlDecode() method.

e.g: Want to insert data like: a>b

C#

cmd.Parameters.Add("@Message", SqlDbType.VarChar, 50).Value = Server.HtmlEncode(txtBIAttenNurse.Text.Trim().Replace("'", "''"));

your code is fine for data insertion.
but when you are fetching the data then be careful what you really want to showing.

if you want to show like a>b then use HtmlDecode() otherwise use plain text.no need to decode the output.
