Scenario:
"This is today's example"
You need to insert following text as value into MySQL:
MySQL doesn't allow us to insert single quote ('), so simply use escape characters.
"This is today''s example"
OR
"This is today\'s example"
//C#
// if you are using textbox value use String.Replace()
string str= textbox1.text
.Replace("'","''");
OR
string str= textbox1.text
.Replace("'","\'");
