OracleCommand::ExecuteReader Method (CommandBehavior)

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

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

public:
OracleDataReader^ ExecuteReader(
	CommandBehavior behavior
)

Parameters

behavior
Type: System.Data::CommandBehavior

One of the CommandBehavior values.

If you expect your SQL statement to return only a single row, specifying SingleRow as the CommandBehavior value may improve application performance.

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

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

More than one OracleDataReader can be open at any given time.

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

No code example is currently available or this language may not be supported.
