Fix for bug#47963: Wrong results when index is used
Problem: using null microsecond part (e.g. "YYYY-MM-DD HH:MM:SS.0000")
in a WHERE condition may lead to wrong results due to improper
DATETIMEs comparison in some cases.
Fix: as we compare DATETIMEs as strings we must trim trailing 0's
in such cases.
