OdbcCommand Methods

The OdbcCommand type exposes the following members.

  Name Description
Public method Cancel Tries to cancel the execution of an OdbcCommand. (Overrides DbCommand.Cancel().)
Public method CreateObjRef Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public method CreateParameter Creates a new instance of an OdbcParameter object.
Public method Dispose() Releases all resources used by the Component. (Inherited from Component.)
Public method Equals(Object) Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public method ExecuteNonQuery Executes an SQL statement against the Connection and returns the number of rows affected. (Overrides DbCommand.ExecuteNonQuery().)
Public method ExecuteNonQueryAsync() An asynchronous version of ExecuteNonQuery, which executes a SQL statement against a connection object.Invokes ExecuteNonQueryAsync with CancellationToken.None. (Inherited from DbCommand.)
Public method ExecuteNonQueryAsync(CancellationToken) This is the asynchronous version of ExecuteNonQuery. Providers should override with an appropriate implementation. The cancellation token may optionally be ignored.The default implementation invokes the synchronous ExecuteNonQuery method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellation token. Exceptions thrown by ExecuteNonQuery will be communicated via the returned Task Exception property.Do not invoke other methods and properties of the DbCommand object until the returned Task is complete. (Inherited from DbCommand.)
Public method ExecuteReader() Sends the CommandText to the Connection and builds an OdbcDataReader.
Public method ExecuteReader(CommandBehavior) Sends the CommandText to the Connection, and builds an OdbcDataReader using one of the CommandBehavior values.
Public method ExecuteReaderAsync() An asynchronous version of ExecuteReader, which executes the CommandText against the Connection and returns a DbDataReader.Invokes ExecuteDbDataReaderAsync with CancellationToken.None. (Inherited from DbCommand.)
Public method ExecuteReaderAsync(CancellationToken) An asynchronous version of ExecuteReader, which executes the CommandText against the Connection and returns a DbDataReader. This method propagates a notification that operations should be canceled.Invokes ExecuteDbDataReaderAsync. (Inherited from DbCommand.)
Public method ExecuteReaderAsync(CommandBehavior) An asynchronous version of ExecuteReader, which executes the CommandText against the Connection and returns a DbDataReader.Invokes ExecuteDbDataReaderAsync. (Inherited from DbCommand.)
Public method ExecuteReaderAsync(CommandBehavior, CancellationToken) Invokes ExecuteDbDataReaderAsync. (Inherited from DbCommand.)
Public method ExecuteScalar Executes the query, and returns the first column of the first row in the result set returned by the query. Additional columns or rows are ignored. (Overrides DbCommand.ExecuteScalar().)
Public method ExecuteScalarAsync() An asynchronous version of ExecuteScalar, which executes the query and returns the first column of the first row in the result set returned by the query. All other columns and rows are ignored.Invokes ExecuteScalarAsync with CancellationToken.None. (Inherited from DbCommand.)
Public method ExecuteScalarAsync(CancellationToken) This is the asynchronous version of ExecuteScalar. Providers should override with an appropriate implementation. The cancellation token may optionally be ignored.The default implementation invokes the synchronous ExecuteScalar method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellation token. Exceptions thrown by ExecuteScalar will be communicated via the returned Task Exception property.Do not invoke other methods and properties of the DbCommand object until the returned Task is complete. (Inherited from DbCommand.)
Public method GetHashCode Serves as the default hash function. (Inherited from Object.)
Public method GetLifetimeService Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method InitializeLifetimeService Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public method Prepare Creates a prepared or compiled version of the command at the data source. (Overrides DbCommand.Prepare().)
Public method ResetCommandTimeout Resets the CommandTimeout property to the default value.
Public method ToString Returns a String containing the name of the Component, if any. This method should not be overridden. (Inherited from Component.)

Explicit interface implemetation Private method IDbCommand.CreateParameter Creates a new instance of an IDbDataParameter object. (Inherited from DbCommand.)
Explicit interface implemetation Private method IDbCommand.ExecuteReader() Executes the CommandText against the Connection and builds an IDataReader. (Inherited from DbCommand.)
Explicit interface implemetation Private method IDbCommand.ExecuteReader(CommandBehavior) Executes the CommandText against the Connection, and builds an IDataReader using one of the CommandBehavior values. (Inherited from DbCommand.)
