I´m having a problem with count of null values fields and indexes...

I have a table (tb_Propose) with around 8 million lines.

A field Dt_flag -- Datetime

An index Ix_Dt_flag, nonclustered, with field Dt_flag, only

When I do the "select count(*) from tb_Propose where Dt_Flag is null", the results comes so different from real... When I do "reindex",...
