I am writing an application in Perl to handle data from a MySQL database.

  • 0

I am writing an application in Perl to handle data from a MySQL database. I need to select only records that have a valid ISO format date, YYYY-MM-DD. However a lot of the records don’t have a value for the month or day, so they are like this 1999-00-00. I need to filter these out.

I could do it with Perl, but I think the best way to do it would be to use the REGEXP function in the SQL statement; however I’m not sure if this is the best way; nor do I know how I would regex the data.

Thanks for any suggestions!

    You could always just use:

    where DATE_COL not like '%-00-00'
