select all years between two dates

[fife]

Im trying to create a repeated list of all the years forms have been filled in, in my database.  The database has been running for 4 years and the row creation_date is unixtime.

 

I want a list that looks as follows

 

2010

2011

2012

2013

 

to create this list I understand Im after creation_date between the highest and lowest value of Year in unixtime.  So I wrote the following query

 

 mysql_select_db($database_dbconnet, $dbconnet); $query_rs_frmyear = sprintf("SELECT creation_date FROM customer_details WHEREcreation BETWEEEN (SELECT MIN(DATE_FORMAT(FROM_UNIXTIME(creation_date), 'Y')) AS lowyear FROM customer_details)AND (SELECT MAX(DATE_FORMAT(FROM_UNIXTIME(creation_date), 'Y')) AS highyear FROM customer_details)"); $rs_frmyear = mysql_query($query_rs_frmyear, $dbconnet) or die(mysql_error());     //echo the yearsdo {echo $row_rs_frmyear['creation_date'];   } while($row_rs_frmyear = mysql_fetch_assoc($rs_frmyear));

 

 

Which fell flat on its face!!! Any ideas anyone?

SELECT DISTINCT(DATE_FORMAT(FROM_UNIXTIME(creation_date), 'Y')) AS year FROM customer_details ORDER BY creation_date

Hi Jessica. Unfortunately that doesn't work and echos nothing when I run the loop.

 

Awesome how you think in such simple terms Jessica thank you for your help. It still amazes me how complicated I tend to try and make things for myself.

There's no need to find the highest and lowest values, just leave the condition out of the where clause and it will grab everything:

edit:added from unixtime

SELECT 
   YEAR(FROM_UNIXTIME(creation_date)) as year
FROM customer_details 

You should also be using a while loop, not a do/while loop. You need to fetch the row first, then process it. A do/while loop works the other way and tries to process it then fetch it.

Brill thanks all. It now works using

 

SELECT DISTINCT YEAR(FROM_UNIXTIME(creation_date)) as year FROM customer_details ORDER BY creation_date ASC
