executeSelectForUpdate

protected void executeSelectForUpdate(String statement,

Specified by:

executeSelectForUpdate in class DbSqlSession

executeDbOperations

public FlushResult executeDbOperations(List<DbOperation> operations)

Description copied from interface: PersistenceSession

Attempts to perform the operations in order and returns a flush result. The result indicates if there are operations that were not successful (via FlushResult.getFailedOperations() and if some operations were not executed (via FlushResult.getRemainingOperations(). The remaining operations must be a suffix of the parameter (e.g. for operations [a, b, c, d], [c, d] is a valid list of remaining operations, [b, c] is not).

This method modifies the operation's state, i.e. DbOperation.getState() will be updated by calling this method:

• Successful operations: DbOperation.State.APPLIED
• Failed operations: DbOperation.State.FAILED_ERROR or DbOperation.State.FAILED_CONCURRENT_MODIFICATION.
• Remaining operations: DbOperation.State.NOT_APPLIED

In addition, the number of affected rows and failure (if any) is updated in the operation.
