Last week, Ola published a very useful update to his Backup, Integrity Check and Index Optimization scripts: the solution now supports updating statistics. There are several options, such as only updating when the data has been modified and using the RESAMPLE and NORECOMPUTE options. An example call:
EXEC dbo.IndexOptimize @|/4/>Databases = 'USER_DATABASES', @FragmentationHigh_LOB = 'INDEX_REBUILD_OFFLINE', @FragmentationHigh_NonLOB = 'INDEX_REBUILD_ONLINE', @FragmentationMedium_LOB = 'INDEX_REORGANIZE_STATISTICS_UPDATE', @FragmentationMedium_NonLOB = 'INDEX_REORGANIZE_STATISTICS_UPDATE', @FragmentationLow_LOB = 'STATISTICS_UPDATE', @FragmentationLow_NonLOB = 'STATISTICS_UPDATE', @UpdateColumnStatistics = 'Y', @OnlyModifiedStatistics = 'Y';
If you haven't already tried Ola's maintenance solution, I highly suggest you check it out.
