Remarks

A BigcommerceConnection object represents a unique connection to BigCommerce. Use it in conjunction with BigcommerceCommand, BigcommerceDataReader, BigcommerceDataAdapter or other components for convenient interoperation with BigCommerce.

When you create an instance of BigcommerceConnection, all properties are set to their initial values. For a list of these values, see ConnectionString.

If the BigcommerceConnection goes out of scope, it is not closed. Therefore, you must explicitly close the connection by calling Devart.Common.DbConnectionBase.Close.

Note that BigcommerceConnection instance is not guaranteed to be thread safe. You should avoid using the same BigcommerceConnection in several threads at the same time. It is recommended to open a new connection per thread and to close it when the work is done. Actually, connections will not be created/disposed every time with the Pooling=true; connection string option - connections will be stored at connection pool. This boosts performance greatly.

A single BigcommerceConnection can be used by many BigcommerceCommand objects on the assumption that all operations will be done consecutively. In other words, you can not execute a SQL statement while an asynchronous operation is in progress.

This class supports cross-form data binding with the InterForm Technology.

Example

The following example creates a BigcommerceCommand and a BigcommerceConnection. The BigcommerceConnection is opened and set as the Connection property. The example then calls ExecuteNonQuery method, and closes the connection. To accomplish this, the ExecuteNonQuery is passed a connection string and a query string that is SQL INSERT statement.

csharp

public void InsertRow(string bigcommerceConnectionString)
{
  // If the connection string is empty, use default.
  if(bigcommerceConnectionString == "")
  {
    bigcommerceConnectionString = 
        "Server=https://bigcommerce-store.mybigcommerce.com/api/v2/;User Id=User;Authentication Token=qweASDzcx1234567890rtyuiqweASDzcx1234567;";
  }
  BigcommerceConnection myConn = new BigcommerceConnection(bigcommerceConnectionString);
  string myInsertQuery = "INSERT INTO customers (firstname, lastname, email) VALUES ('John','Smith','[email protected]')";
  BigcommerceCommand bigcommerceCommand = new BigcommerceCommand(myInsertQuery);
  bigcommerceCommand.Connection = myConn;
  myConn.Open();
  try
  {
    bigcommerceCommand.ExecuteNonQuery();
  }
  finally
  {
    myConn.Close();
  }
}

Visual Basic

Public Sub InsertRow(bigcommerceConnectionString As String)
  ' If the connection string is empty, use default.
  If bigcommerceConnectionString = "" Then
    bigcommerceConnectionString = _
        "Server=https://bigcommerce-store.mybigcommerce.com/api/v2/;User Id=User;Authentication Token=qweASDzcx1234567890rtyuiqweASDzcx1234567;"
  End If
  Dim myConn As New BigcommerceConnection(bigcommerceConnectionString)
  Dim myInsertQuery As String = "INSERT INTO customers (firstname, lastname, email) VALUES ('John','Smith','[email protected]')"
  Dim bigcommerceCommand As New BigcommerceCommand(myInsertQuery)
  bigcommerceCommand.Connection = myConn
  myConn.Open()
  Try
    bigcommerceCommand.ExecuteNonQuery()
  Finally
    myConn.Close()
  End Try
End Sub
