I'm trying to get a date value with: - Current year - Current month - Day number from one select
the query
SELECT rat_data FROM rate_unita WHERE rateid = 1
as a result one INT value.
When I try to execute the following:
SELECT DATE(CONCAT(YEAR(NOW())),(MONTH(NOW())), (SELECT rat_data FROM rate_unita WHERE rateid = 1))
Mysql mark my syntax as incorrect near ' ( MONTH( NOW( ) ) ) , ( SELECT rat_data FROM rate_unita WHERE r
I think that there is something wrong with the way I'm calling the SELECT in the CONCAT, what is the correct query to reach my goal?
Thanks L
You're closing the concat function too early. Remove some extra parentheis
SELECT DATE(CONCAT(YEAR(NOW()),
MONTH(NOW()),
(SELECT rat_data FROM rate_unita WHERE rateid = 1)
))
But you need to add some hyphens to make it a true date value
SELECT DATE(
CONCAT(
YEAR(NOW()),
'-',
MONTH(NOW()),
'-',
(SELECT rat_data FROM rate_unita WHERE rateid = 1)
)
)
This should result in a date of YEAR-MONTH-rat_data
Here's a working SQL Fiddle
Use DATE_FORMAT function. Here are a few examples: http://www.w3schools.com/sql/func_date_format.asp http://www.mysqltutorial.org/mysql-date_format/
