Question

in my table i have a column current_date the value is 2012-11-27.

heres my code

$query = QModel::query("SELECT * FROM transaction WHERE current_date='$order_date'"); 

The value of $order_date is year-month only “2012-10“, how can i split the current_date into year-month only “2012-10“…

should I use CHARINDEX to split the current_date??? how please…

thanks

Answer 1

well if you need to select all records within one month you can do follows:

SELECT * 
FROM table
WHERE current_date >= convert(datetime, '20121001', 112) and current_date < convert(datetime, '20121101', 112)

I cannot advice to use month and year functions because your indexes will not work

update: AFAIK, in MySQL it will be

SELECT * 
FROM table
WHERE current_date >= str_to_date('20121001', '%y%m%d') and current_date < str_to_date('20121101', '%y%m%d')
