I got it working , thank you.
I only could do what I wanted to do in multisteps however. I couldn't
figure out the nested querying , and it's bugging me.
Here's how I issued it.
mysql> update tableDummy set newDate=(select
str_to_date('(concat(DayVal,".",MonthVal,".",YearVal))','%d.%m.%Y'));
That's because there is no nested querying needed here. The syntax is SET col = newvalue. This would have worked if you'd simply left out the "select".
Also, there would be no need for STR_TO_DATE() if you use CONCAT() to put the string in the correct form in the first place.
Try
UPDATE tableDummy SET newDate = concat(YearVal,"-",MonthVal,"-",DayVal)
instead.

And although I got an error, it did give all zero values for the date(e.g 0000-00-00)
no big deal now that I have what I want, but if someone can pick out my error, would be greatly apreciated.

Hello, I have a table with separate integer values for the day, month and year. I would like to group them all under one field of type date. I tried a few commands but I haven't captured the right syntax yet.
so if the field names are dayVal,monthVal and YearVal in talbeDummy
I am doing the following select str_to_date(DayVal.MonthVal.YearVal,'%d.%m.%Y') from tableDummy;
CONCAT(DayVal, ".", MonthVal, ".", YearVal)
