Question

I want to know how to execute more than one SQL command at once.

At this moment I’m doing it like this:

using (SqlConnection sqlConnection1 = new SqlConnection(connectionString))
{
    using (SqlCommand cmd = new SqlCommand())
    {
        cmd.CommandText = "SELECT nome FROM teste";
        cmd.CommandType = CommandType.Text;
        cmd.Connection = sqlConnection1;

        sqlConnection1.Open();

        // execute the command
        SqlDataReader rdr = cmd.ExecuteReader();
        while (rdr.Read())
        {
            listBox1.Items.Add(rdr["name"].ToString()); 
        }
    }
}

But how can I do to execute

use [databaseX]
SELECT nome FROM teste

in my c# program?

Answer 1

Separate multiple statements with a semicolon (;).

(BTW, the use statement is generally not needed because it’s set in your connection string.)
