I have date written like this : 01/12/2013 -- how can I display only the first two letter using REGEXP. Thanks
You could use SUBSTRING_INDEX function instead of a regexp:
SELECT SUBSTRING_INDEX(column, '/', 1)
FROM yourtable
You can also use LEFT function
SELECT LEFT(datecol,2) FROM `table`

Can anybody provide me regular expression for multiple of 100.
we want to validate value in multiple of 100 .
Regards,
Pradeep
I'd use this:
^[1-9]+[0-9]*00$
First number must be from 1 to 9, then any number of random digits, and it must end in two 0's.
In future looking up a bit of regex would be a good first step, this is very very simple and can be worked out (even by a complete novice) in very little time.
what about this
([0-9]*00)|0
you can check above expression here

I firstly trying to show the records with this query, which is no way near to the solution.

Any help will be appriciated.

Are you looking for something like this?
UPDATE question
SET questionLink = REPLACE(questionLink, '.jpg', '.png');
