A basic operation performed against a database (i.e., a query or command).
| def Library.DataSource.Databases.ADataOperation.__init__ | ( | Self, | |
| params | |||
| ) |
Construct a new data operation that will operate on the specified data source.
The constructor expects the following items to be provided in params:
DataSource – a reference to the instance of ADataSource on which the data operation is to take place. | def Library.DataSource.Databases.ADataOperation.execute | ( | Self | ) |
Execute the operation.
This routine should be implemented by descendants of ADataOperation. It should return a status code to indicate whether the command or query was accepted and executed by the data source. It should also store this status code in the public 'result' attribute. A status code of zero (0) should be used to indicate success.
This method generates the execute event.
| def Library.DataSource.Databases.ADataOperation.handle | ( | Self | ) |
Retrieve the handle assigned to the operation by the data source.
| def Library.DataSource.Databases.ADataOperation.message | ( | Self | ) |
Retrieve the message generated by the data source while executing the operation, if any.
| def Library.DataSource.Databases.ADataOperation.result | ( | Self | ) |
Retrieve the result code returned by the data source after executing the operation.
| def Library.DataSource.Databases.ADataOperation.runtime | ( | Self | ) |
Retrieve the amount of time elapsed while executing the operation.
| def Library.DataSource.Databases.ADataOperation.Source | ( | Self | ) |
Retrieve the data source used by the operation.
