Question

I am new to C# Windows Application coding and using Enterprise library.

I want to insert records into SQL Server 2008 database using Enterprise Library 4.1

I am getting confused between SQLCommand and DBCommand which one to use and when to use.

Answer 1

You don’t need to use EntLib, just use old good ADO.NET:

using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlCommand command = connection.CreateCommand())
{
    command.CommandText = "INSERT INTO table (column) VALUES (@param)";

    command.Parameters.AddWithValue("@param", value);

    connection.Open();
    command.ExecuteNonQuery();
}

Here’s the class signature on MSDN:

public sealed class SqlCommand : DbCommand, ICloneable

SqlCommand derives from DbCommand
