메소드 설명
BigQueryCommand ( ) : System

Initializes a new instance of the BigQueryCommand class with default settings.

BigQueryCommand ( BigQueryCommand command ) : System

Initializes a new instance of the BigQueryCommand class with the specified prototype.

BigQueryCommand ( string commandText ) : System

Initializes a new instance of the BigQueryCommand class with the specified command text.

BigQueryCommand ( string commandText, BigQueryConnection connection ) : System

Initializes a new instance of the BigQueryCommand class with the specified command text and connection settings.

Cancel ( ) : void

Cancels the execution of the current BigQueryCommand.

ExecuteNonQuery ( ) : int

Executes a non-query SQL statement and returns the number of rows affected.

ExecuteNonQueryAsync ( CancellationToken cancellationToken ) : Task

Asynchronously executes a non-query SQL statement. The asynchronous result contains the number of rows affected.

ExecuteScalar ( ) : object

Executes a SQL statement and returns the first column of the first row of the resulting data.

ExecuteScalarAsync ( CancellationToken cancellationToken ) : Task

Asynchronously executes a SQL statement. The asynchronous result contains the first column of the first row of the resulting data.

Prepare ( ) : void

Creates a prepared (or compiled) version of the command on the data source. This implementation always throws NotSupportedException.
