Re: Filtering Entries by Complex Date

[Christopher Esbrandt]

The only change had been to the CASE WHEN END from what I originally posted:

SELECT needDate FROM courses WHERE CASE WHEN needDate IS NULL THEN '20120101' WHEN CHAR_LENGTH(needDate) > 6 THEN DATE_FORMAT(STR_TO_DATE(needDate, '%m/%d/%Y'), '%Y%m%d') WHEN CHAR_LENGTH(needDate) > 4 THEN DATE_FORMAT(STR_TO_DATE(needDate, '%Y%m'), '%Y%m01') ELSE DATE_FORMAT(STR_TO_DATE(needDate, '%Y'), '%Y0101') END BETWEEN DATE_FORMAT(STR_TO_DATE('11/29/2013', '%m/%d/%Y'), '%Y%m%d') AND DATE_FORMAT(STR_TO_DATE('06/17/2014', '%m/%d/%Y'), '%Y%m%d');

That's the latest attempt with the updated CASE...WHEN...END and trying to format it in a manner where it should be easily sortable.
