/**
 * Represents an exception during {@link JdbcDataContext#executeUpdate(org.apache.metamodel.UpdateScript)} which was
 * rolled back at the JDBC layer. This particular exception type can typically be caught and the update can be retried
 * to retry the transaction (assuming that the script is designed in a way that makes it idempotent and has not
 * side-effects on state outside of the {@link JdbcDataContext}).
 * 
 * Note that the cause of this will always be a {@link SQLException} since it only applies to JDBC.
