I will need to find the last movement (higher) for a given date ordering by numeric code ascending to find the price field.
Suppose that i will have 3 movement with the same date, ex. 31.07.2015 where the first numeric code is 9, the secund is 10 and finally
the last is 25.
I need to write

Select max(datalc) from mytable where max(datalc) ="31.07.2015" order by numeric code desc

How to compare max(datalc) with the given date?
Max(datalc)=ctod('31.07.2015'), is this correct?

Thanks for your Help.
Best regards,
Luis
