Connection Property (MySqlCommand)

In This Topic

Gets or sets the MySqlConnection used by this instance of the MySqlCommand.

Syntax

Visual Basic
C#

'Declaration
 
Public Shadows Property Connection As MySqlConnection

public new MySqlConnection Connection {get; set;}

Property Value

The connection to a data source. The default value is a null reference.

Remarks

MySqlConnection specified in this property will carry out all operations executed with this MySqlCommand.

This property supports the InterForm technology.

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

Example

The following example creates a MySqlCommand and sets some of its properties.

csharp

public void CreateCommand()
{
  string mySelectQuery = "SELECT * FROM Test.Dept ORDER BY DeptNo";
  MySqlCommand myCommand = new MySqlCommand(mySelectQuery);
  myCommand.Connection = new MySqlConnection(
    "User Id=root;Host=localhost;Database=Test;");
  myCommand.CommandType = System.Data.CommandType.Text;
}

Visual Basic

Public Sub CreateCommand()
  Dim mySelectQuery As String = _
    "SELECT * FROM Test.Dept ORDER BY DeptNo"
  Dim myCommand As New MySqlCommand(mySelectQuery)
  myCommand.Connection = New MySqlConnection( _
    "User Id=root;Host=localhost;Database=Test;")
  myCommand.CommandType = System.Data.CommandType.Text
End Sub
