OracleCommand Class

Represents an SQL statement or stored procedure to execute against a database. This class cannot be inherited.

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

public final class OracleCommand extends DbCommand implements ICloneable

The OracleCommand class provides the following methods for executing commands against a data source:




Executes commands that return rows.


Executes an SQL statement against the Connection and returns the number of rows affected.


Executes commands such as SQL INSERT, DELETE, UPDATE, and SET statements.


Retrieves a single value (for example, an aggregate value) from a database as a .NET Framework data type.


Retrieves a single value (for example, an aggregate value) from a database as an Oracle-specific data type.

You can reset the CommandText property and reuse the OracleCommand object.

If execution of the command results in a fatal OracleException, the OracleConnection may close. However, the user can reopen the connection and continue.


Unlike the Command object in the other .NET Framework data providers (SQL Server, OLE DB, and ODBC), the OracleCommand object does not support a CommandTimeout property. Setting a command timeout has no effect and the value returned is always zero.

The following example uses the ExecuteReader method of OracleCommand, along with OracleDataReader and OracleConnection, to select rows from a table.

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

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
