I'm trying to leverage 'date_trunc' function in a query and it returns the below error
FUNCTION database.date_trunc does not exist.
Please advice
You could use DATE_FORMAT(created_at ,'%Y-01-01') to get first day of year:
SELECT DATE_FORMAT(created_at ,'%Y-01-01') AS `year`, COUNT(*) AS cnt
FROM sales_order
GROUP BY DATE_FORMAT(created_at ,'%Y-01-01')
ORDER BY `year`;
DATE_TRUNC is supported by PostgreSQL.

Mysql to select month-wise record even if data not exist
(2 answers)

I have a table with a column date and a column ID (to keep it simple). I am doing a query to count the total and group by week
SELECT MONTH(table1.Date_1st), YEAR(table1.Date_1st), COUNT(table1.Id)
FROM table1 as table1
WHERE Date_1st BETWEEN '2013-04-01' AND '2013-07-25'
GROUP BY WEEK(Date_1st)
the problem is there is no results on specific week the result is not taken into consideration. I already try ifnull(table1.Id,0)
Try ISNULL or other NULL SQL functions:
NULL functions
ISNULL returns a 0 if the value is null.
