xyph Posted December 16, 2011 Share Posted December 16, 2011 The AND clause shouldn't be there. You should check out the error function of whatever database flavor you're using. In MySQL, it's mysql_error. That will contain an error message, if any should occur.

xyph Posted December 16, 2011 Share Posted December 16, 2011 My guess is there isn't a row where `ApID` = '33236' Link to comment https://forums.phpfreaks.com/topic/253275-gps-coordinates-and-float-issue-lengthvalue/#findComment-1298635 Share on other sites More sharing options...

xyph Posted December 19, 2011 Share Posted December 19, 2011 It won't update the row if it doesn't need to. Change one of the values, and it will update.

Pikachu2000 Posted December 28, 2011 Share Posted December 28, 2011 Real simple test: does "SELECT * WHERE ApID = '33236'" return any results?

Pikachu2000 Posted December 30, 2011 Share Posted December 30, 2011 If you actually ran the select query and it produced results, then I don't see any reason for the UPDATE query to fail.

dflow Posted January 1, 2012 Author Share Posted January 1, 2012 If you actually ran the select query and it produced results, then I don't see any reason for the UPDATE query to fail. yep i dont get it myself, i have 0 affected rows ... i thought it's something to do with the float structure.

Pikachu2000 Posted January 1, 2012 Share Posted January 1, 2012 One last thought. Make sure the fields for latitude and longitude are set as UNSIGNED.
