ExecuteReader(CommandBehavior) Method

Sends the CommandText to the Connection, and builds a OracleDataReader using one of the CommandBehavior values.

[Visual Basic]
Overloads Public Function ExecuteReader( _
   ByVal behavior As CommandBehavior _
) As OracleDataReader

[C#]
public OracleDataReader ExecuteReader( 
   CommandBehavior behavior
);

Parameters

behavior: One of the CommandBehavior values.

Return Type

A OracleDataReader object.

Remarks

The OracleDataReader supports a special mode that enables large binary values to be read efficiently. For more information, see the SequentialAccess setting for CommandBehavior.

Example

The following example creates a OracleCommand, then executes it by passing a string that is SQL SELECT statement, and a string to use to connect to the database. The CommandBehavior is then set to CloseConnection.

[C#]

public void CreateOracleDataReader(string mySelectQuery,string myConnectionString) 
{ 
  OracleConnection myConnection = new OracleConnection(myConnectionString); 
  OracleCommand myCommand = new OracleCommand(mySelectQuery, myConnection); 
  myCommand.Connection.Open(); 
  OracleDataReader myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection); 
  while(myReader.Read()) 
  { 
    Console.WriteLine(myReader.GetString(0)); 
  } 
  myReader.Close(); 
}

[Visual Basic]

Public Sub CreateOracleDataReader(mySelectQuery As String, _
 myConnectionString As String)
   Dim myConnection As New OracleConnection(myConnectionString)
   Dim myCommand As New OracleCommand(mySelectQuery, myConnection)
   myCommand.Connection.Open()
   Dim myReader As OracleDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection)
   While myReader.Read()
     Console.WriteLine(myReader.GetString(0))
   End While
   myReader.Close()
 End Sub
