How To Select Data From Database With Many Filter Options?

You should always prefer filtering data on database instead of bringing unwanted data to your application and filtering with code.

In the string below you add a WHERE clause and pairs of column = value or column = expression

 string query = "SELECT * FROM MyTable WHERE column1=somevalue AND column2 > somevalue AND ...";
