Question

I want to create a ASP.NET page which contains a multi-line textbox. Whatever query i will write in it for my db , the query should get executed.

Like if I want to update a stored procedure then also i should be able to do that.
How to achieve this?

Answer 1

I suppose you know about security issues. Use standard SqlConnection and SqlCommand classes.

using(var cnn = new SqlConnection("-my-connection-string-")){
    using(var cmd = cnn.CreateCommand()) {
        cmd.CommandText = this.txtSqlCommand.Text;
        cmd.ExecuteNonQuery();
    }
}
