adding dates, DATEADD function

[rodrigo21]

Hello,

I have one form with a field for entering a date 'orderdate' and another field for entering a days interval 'range'.
This form is used to preform a query on a travel tickets database, so that I can search for tickets with dates from ('orderdate') till ('orderdate' + 'range').

For achieving this I have the followiong code:
[php]
"SELECT * FROM viajes WHERE viajes.fecha BETWEEN DATEADD(Day,'". $_GET['rango'] ."','". $_GET['orderdate'] ."') AND '". $_GET['orderdate'] ."'";
[/php]
but Iam getting this error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(Day,'4','2008-03-29') AND '2008-03-29' LIMIT 0, 10' at line 1

I dont know if maybe I should use the mysql function DATE_ADD instead of sql DATEADD function,?

Any help is welcome.

note: at least the information from my form seems to be correctly coded in the query: 2008-03-29, as the error shows

Hi, es, your query syntax is worng to add the date. So try with the following query.
[code=mysql]
SELECT *
FROM viajes
WHERE
viajes.fecha BETWEEN orderdate AND DATE_ADD(orderd ate,INTERVAL rango DAY);[/code]
Here,
[php]rango = $_GET['rango']
orderdate = $_GET['orderdate'][/php]
So u can format the query as per the PHP concatination syntax.
For general, date add function

Syntax:
[code=mysql]DATE_ADD(date,I NTERVAL expr unit);[/code]
Example:[code=mysql]SELECT DATE_ADD(DATE(N OW()),INTERVAL 2 DAY) AS DT;[/code]I hope.. this will help you...
Good Luck...

Ok thanks a lot, it works now. This is the code I use:

[code=mysql]"SELECT * FROM viajes WHERE viajes.fecha BETWEEN '". $_GET['orderdate'] ."' AND DATE_ADD('". $_GET['orderdate'] ."',INTERVAL '". $_GET['rango'] ."' day)";[/code]

Could you tell me why I had to use the DATE_ADD instead of the DATEADD function? I think I am lost in between SQL and MYSQL

DATEADD does not exist as a MySQL function, DATE_ADD is the correct one.

Btw rodrigo21: what is your comment on the reply to a previous thread of yours at this link http://www.thescripts.com/forum/post3115825-16.html ?
