The optimizer may get more accurate estimates of selectivity if you can create histograms with a sufficiently large number of buckets You may also be able to work around some problems by creating function-based indexes that restate the data in the correct type if you can also change the SQL to match Applications that use special values instead of nulls in columns are liable to produce poor execution plans if the columns are used in range-based predicates Again, a histogram on the critical column may make an enormous difference Applying functions to columns that do not participate in function-based indexes can lead to some unexpected selectivities You may even find that restating the same clause in a different way can lead to a significant change in selectivity because of some of the inconsistencies of the fixed constants used for the selectivity in these cases. vb.net code 39 reader C# .
