How to give ADO.NET Parameters

Question

I want to create a SQL command that adds record to DB. I tried the following code but it doesn\'t seem to be working:

SqlCommand comand = new SqlCommand(\"IN         


        

Answer 1

In your case, it looks like you're using .NET. Using parameters is as easy as:

C#

 string sql = "SELECT empSalary from employee where salary = @salary";
 SqlConnection connection = new SqlConnection(/* connection info */);
 SqlCommand command = new SqlCommand(sql, connection);

 command.Parameters.AddWithValue("salary", txtSalary.Text);
