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