Method Detail

executeUpdate

void executeUpdate(UpdateScript update)

Submits an UpdateScript for execution on the DataContext. Since implementations of the DataContext vary quite a lot, there is no golden rule as to how an update script will be executed. But the implementors should strive towards handling an UpdateScript as a single transactional change to the data store.

Parameters:

update - the update script to execute
