Remarks

The MagentoCommand class provides the following methods for executing commands against Adobe Commerce:

Item	Description
ExecuteReader	Executes commands that return rows.
Devart.Common.DbCommandBase.ExecutePageReader	Returns a specific subset of rows when paging through the results of a query.
ExecuteNonQuery	Executes SQL commands such as INSERT, DELETE, UPDATE.
ExecuteScalar	Retrieves a single value (for example, an aggregate value) from a data source.

If execution of the command results in a fatal MagentoException, the MagentoConnection may close. However, the user can reopen the connection and continue.

Example

The following example uses the ExecuteReader method of MagentoCommand, along with MagentoDataReader and MagentoConnection, to select rows from a table.

public void ReadMyData(string myConnString)
{
  string mySelectQuery = "SELECT customer_id, lastname FROM Customers";
  MagentoConnection adobe commerceConnection = new MagentoConnection(myConnString);
  MagentoCommand adobe commerceCommand = new MagentoCommand(mySelectQuery,adobe commerceConnection);
  adobe commerceConnection.Open();
  MagentoDataReader adobe commerceReader = adobe commerceCommand.ExecuteReader();
  try
  {
    while (adobe commerceReader.Read())
    {
      Console.WriteLine(adobe commerceReader.GetInt32(0).ToString() + ", " + adobe commerceReader.GetString(1));
    }
  }
  finally
  {
  // always call Close when done reading.
  adobe commerceReader.Close();
  // always call Close when done reading.
  adobe commerceConnection.Close();
  }
}
