Str To Date Not Working

[Alicia]

Hi guys,

 

can somebody give me an idea why this query doesn't work? thanks

 

SELECT SUM(credit) AS usage,  STR_TO_DATE(`created`, '%m/%d/%y'),STR_TO_DATE(`expiry`, '%m/%d/%y') FROM `suax` WHERE  STR_TO_DATE(`created`, '%m/%d/%y') >= '11/5/2012' AND STR_TO_DATE(`expiry`, '%m/%d/%y') = '11/15/2012' LIMIT 0 , 30

 

my created and expiry format is a string like this 1/15/2012 04:05:22

 

 

Please advise.thanks

In what way does it not work, pray tell?

[Alicia]

i just want to filter the records by referrring to the date i have in the column but currently it is in varchar so i couldn't filter by date range

Again, in what way is it not working?

[Alicia]

i am not sure... there is a syntax error when i run the query

One problem I see is that 1/15/2012 04:05:22 is NOT '%m/%d/%y'. 1/15/2012 would be %m/%d/%y. I've NEVER used that function so I don't know if that it is.

 

However, you got a syntax error, and you didn't post it...why exactly?

So many errors!

 

You are not correctly defining the current format to be converted (see Jessica's reply)

You are converting to mysql date format yet comparing against your string format (use >= 'yyyy-mm-dd' etc)

You logic is screwed - you look for those greater than one date AND equal to another (only ever returning the latter)

You need column aliases for your converted dates

 

EDIT:

The time element will be ignored

mysql> select STR_TO_DATE('22/01/2012 09:30:00','%d/%m/%Y') as dob;
