Solution 1

Google for two things. First, "Sql Injection Attack" to find out why what you're doing is so dangerous to your database and then "C# sql parameterized query" to find out how to mitigate that problem to a very large degree and fix your INSERT problem at the same time.

Yes, please follow the Solution #1. You can cause the SQL Injection[^]. Always go with parameterized query.

And the solution:

SQL

sql = "INSERT INTO table (name, email, description) VALUES ('myname', 'email', 'I can''t insert here with don''t or can't with the word has '' in it')"

You need to escape the single quote with the single quote ;)

Try this & let me know if it works.
