Namespace: System.Data.OracleClient
Assembly: System.Data.OracleClient (in

Public Property Connection As OracleConnection
Dim instance As OracleCommand
Dim value As OracleConnection

value = instance.Connection

instance.Connection = value
/** @property */
public OracleConnection get_Connection ()

/** @property */
public void set_Connection (OracleConnection value)

public function get Connection () : OracleConnection

public function set Connection (value : OracleConnection)

Property Value

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

Exception typeCondition


The Connection property was changed while a transaction was in progress.

You cannot set the Connection, CommandType, and CommandText properties if the current connection is performing an execute or fetch operation.

If you set Connection while a transaction is in progress and the Transaction property is not null, an InvalidOperationException is generated. If you set Connection after the transaction has been committed or rolled back, and the Transaction property is not null, the Transaction property is then set to a null value.

The following example creates an OracleCommand and sets some of its properties.

Public Sub CreateOracleCommand()
    Dim queryString As String = _
       "SELECT * FROM Emp ORDER BY EmpNo"
    Dim command As New OracleCommand(queryString)
    command.CommandType = CommandType.Text
End Sub
