A computer-implemented method dynamically detects and corrects an error in a query. The method includes identifying an error in a first query. The method further includes generating a set of alternate execution structures for the first query. The method includes running each of the alternate execution structures, including generating a set of results corresponding to each set of alternate execution structure, comparing each of the set of results against each other of the set of results, and storing each of the set of alternate execution structures to include a result of the set of results, for each alternate structure. The method further includes selecting, from the set of alternate execution structures, a first alternate execution structure based on a predetermined criteria, and implementing the first alternate structure in place of the first query.
