IDbCommand.ExecuteReader Method (CommandBehavior)

.NET Framework 1.1

Executes the CommandText against the Connection, and builds an IDataReader using one of the CommandBehavior values.

[Visual Basic]
Function ExecuteReader( _
   ByVal behavior As CommandBehavior _
) As IDataReader
[C#]
IDataReader ExecuteReader(
   CommandBehavior behavior
);
[C++]
IDataReader* ExecuteReader(
   CommandBehavior behavior
);
[JScript]
function ExecuteReader(
   behavior : CommandBehavior
) : IDataReader;

Parameters

behavior
One of the CommandBehavior values.

Return Value

An IDataReader object.

Remarks

The caller must call the Open method of the Connection property.

When the CommandType property is set to StoredProcedure, the CommandText property should be set to the name of the stored procedure. The command executes this stored procedure when you call ExecuteReader.

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

While the IDataReader is in use, the associated IDbConnection is busy serving the IDataReader. While in this state, no other operations can be performed on the IDbConnection other than closing it. This is the case until the Close method of the DataReader is called. If the DataReader is created with CommandBehavior set to CloseConnection, closing the DataReader closes the connection automatically.
