How can I select records from next month if I have a column called "month" that contains string representations of the actual month names?
SELECT * FROM minutes WHERE year = YEAR(CURDATE()) AND month =
Got it, never mind:
SELECT * FROM minutes WHERE year = YEAR(CURDATE()) AND month = MONTHNAME(now() + INTERVAL 1 MONTH)

From this database, I want to select those data which payment_date is current month but the service_date is any month except this month.
Database sample
One way to check if 2 dates are in the same month is with the use of the function last_day(), because if for 2 dates the last day of their month is the same then they are in the same month:
select *
from tablename
where last_day(payment_date) = last_day(curdate())
and last_day(service_date) <> last_day(curdate())
If you want the results for any month and not for the current month only:
select *
from tablename
where last_day(payment_date) <> last_day(service_date)
I am trying to introduce a new column for my query, it currently counts sum of expenses in this month, the new column should display last months expences. I am not quite sure where to place it.
SELECT cat.id_kat,
cat.nazwa,
coalesce(exp.tot, 0) AS PriceTotal
FROM wydatki_kategorie cat
LEFT JOIN
(SELECT wydatki_wpisy.kategoria,
sum(wydatki_wpisy.brutto) AS tot
FROM wydatki_wpisy
LEFT JOIN wydatki ON wydatki_wpisy.do_wydatku = wydatki.id_wydatku
WHERE MONTH(wydatki.data_zakupu) = MONTH(CURRENT_DATE())
AND wydatki.id_kupujacy = 1
GROUP BY wydatki_wpisy.kategoria) exp ON cat.id_kat = exp.kategoria
Possibly might be needed ( if I'm not wrong ) - Where clause for the previous month.
wydatki.data_zakupu >= DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 2 MONTH)), INTERVAL 1 DAY) AND
wydatki.data_zakupu<= DATE_SUB(NOW(), INTERVAL 1 MONTH)
SQL Fiddle example
Two things.
First, if you stop using WHERE MONTH(wydatki.data_zakupu) = MONTH(CURRENT_DATE()) to choose your dates you'll get three benefits.
Your date searching will become sargable: an index will speed it up.
You'll get a more general scheme for choosing months.
If you have multiple years' worth of data in your tables, things will work better.
Instead, in general use this sort of expression to search for the present month. You already figured out most of this.
WHERE wydatki.data_zakupu >= LAST_DAY(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 1 MONTH
AND wydatki.data_zakupu < LAST_DAY(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 0 MONTH
This looks for all datetime values on or after midnight at the first day of the present month, and before, but not on <, midnight at the first day of next month.
It generalizes to any month you want. For example,
WHERE wydatki.data_zakupu >= LAST_DAY(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 2 MONTH
AND wydatki.data_zakupu < LAST_DAY(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 1 MONTH
gets you last month. This also works when the current month is January, and it works when you have multiple years' worth of data in your tables.
These expressions are a little verbose because MySQL doesn't have a FIRST_DAY(date) function, only a LAST_DAY(date) function. So we need all that + INTERVAL 1 DAY monkey business.
Second, pulling out a previous month's data is as simple as adding another LEFT JOIN ( SELECT... clause to your table, like so. (http://sqlfiddle.com/#!9/676df4/13)
SELECT ...
coalesce(month1.tot, 0) AS LastMonth
FROM wydatki_kategorie cat
LEFT JOIN
...
LEFT JOIN
(SELECT wydatki_wpisy.kategoria,
sum(wydatki_wpisy.brutto) AS tot
FROM wydatki_wpisy
LEFT JOIN wydatki ON wydatki_wpisy.do_wydatku = wydatki.id_wydatku
WHERE wydatki.data_zakupu >= LAST_DAY(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 2 MONTH
AND wydatki.data_zakupu < LAST_DAY(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 1 MONTH
AND wydatki.id_kupujacy = 1
GROUP BY wydatki_wpisy.kategoria
) month1 ON cat.id_kat = month1.kategoria
As you can see, the date range WHERE clause here gets the previous month's rows.
what will be the smartest way to select all rows from MySQL table for the past 3 months if the table has the following columns:
| id (int) | year (int)| month (int) |
Considering that if the current month & year are for example 2.2016 I need to select all records for 11.2015 & 12.2015 & 1.2016
It is easy if the current month is greater than 3 because all months that I need to select are in the same year so I can subtract 3 from the current month and run simple query
SELECT * FROM mytabe where year=2016 and month >= xx
Select * from mytable where STR_TO_DATE(concat(year,"-",month,"-01"),'%Y-%m-%d')>date_sub(curdate(),Interval 3 month) ;
The above query will get fetch year and month from date 3 months before today
You can select three Months records by these queries follow this.
The columnName means which column data want you select.
The tableName means which table data want you select.
The dateColumnName means which column date base you want to select data.
It would return Last Month data from today.
SELECT columName FROM tableName WHERE dateColumName BETWEEN ( DATE(NOW()) - INTERVAL 1 MONTH) AND Date(Now())
It would return Second Last Month data from today.
SELECT columName FROM tableName WHERE dateColumName BETWEEN ( DATE(NOW()) - INTERVAL 2 MONTH) AND ( DATE(NOW()) - INTERVAL 1 MONTH)
It would return Third Last Month data from today.
SELECT columName FROM tableName WHERE dateColumName BETWEEN ( DATE(NOW()) - INTERVAL 3 MONTH) AND ( DATE(NOW()) - INTERVAL 2 MONTH)
May It help to others.
Please try this
Select * from mytable where STR_TO_DATE(concat(year,"-",month,"-01"),'%Y-%m-%d')>date_sub(curdate(),Interval 3 month) ;
my datefield (artists.onlineDate) is yyy-mm-dd hh:mm:ss
right now I got:
-- Today
SELECT * FROM artists WHERE DATE(artists.onlineDate) = CURDATE()
-- Current Week
SELECT * FROM artists WHERE WEEK(artists.onlineDate, 3) = WEEK(CURDATE(), 3)
-- Current Month
SELECT * FROM artists WHERE MONTH(artists.onlineDate) = MONTH(CURDATE())
-- Current Year
SELECT * FROM artists WHERE YEAR(artists.onlineDate) = YEAR(CURDATE())
But what I need is exact: Yesterday, Last Week, Last Month, Last Year
I try to explain. if we got wednesday, and I use SELECT * FROM artists WHERE DATE(artists.onlineDate) = CURDATE(), then I get monday to wednesday.
I would like to have the monday to sunday of the last week. the calendar week before.
And the same for the month and year.
I thins SUB_DATE is not the right way.
Any suggestions?
OK I found what I was looking for at:
MySQL Query to select data from last week?
SELECT * FROM testwoche
WHERE WEEK (datum, 3) = WEEK(current_date, 3) - 1
AND YEAR(datum) = YEAR(current_date) ORDER BY datum DESC
same for month
SELECT * FROM testwoche
WHERE month (datum) = month(current_date) - 1
AND YEAR(datum) = YEAR(current_date)
ORDER BY datum DESC
This gives back the last week from monday to sunday and the last month
Thanks everybody for helping!
I think you can use the SUBTIME function: https://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_subtime
I haven't had time to really test it, but I think you get the idea:
Yesterday:
SELECT * FROM artists WHERE DATE(artists.onlineDate) = SUBTIME(CURDATE(),'1 0:0:0');
Last Week
SELECT * FROM artists WHERE WEEK(artists.onlineDate, 3) = WEEK(SUBTIME(CURDATE(),'7 0:0:0'), 3)
Last Month
SELECT * FROM artists WHERE MONTH(artists.onlineDate) = MONTH(SUBTIME(CURDATE(),'31 0:0:0'))
Last Year
SELECT * FROM artists WHERE YEAR(artists.onlineDate) = YEAR(SUBTIME(CURDATE(),'365 0:0:0'))
To get a specific week/month/year (which still works when your db contains several years worth of data and when your current time is the start of a new year), this should work:
SELECT * FROM testwoche WHERE
((YEAR(CURDATE())-YEAR(datum)))*52-WEEK(datum,3)+WEEK(CURDATE(),3) = 1;
If you want two weeks ago, you could change it to =2 (if you want current week, from Monday to current day: =0). If you want last month, you change the WEEK function to MONTH.
I have a table in my database with two columns: month (1-12) and year (yyyy).
I need to select records between two dates, for exemple
select * from Calendar a where SOMEDATE between STARTDATE and ENDDATE.
So the question is: how can I create the STARTDATE and the ENDDATE from this two columns I have?
...where SOMEDATE between
STR_TO_DATE(CONCAT_WS('-',STARTYEAR,STARTMONTH,1),'%Y-%m-%d')
and
DATE_SUB(
STR_TO_DATE(CONCAT_WS('-',ENDYEAR,ENDMONTH + 1,1),'%Y-%m-%d')
, INTERVAL DAY 1
)
Note that we convert both parts to type date, and use date_sub to subtract a single day from ENDMONTH + 1, since we don't know how many days there are in the relevant month.
You can use this solution to make date from the year and month fields-
SELECT MAKEDATE(year, 1) + INTERVAL month - 1 MONTH FROM calendar;
The apply this one to WHERE condition, e.g. -
SELECT * FROM Calendar a
WHERE
MAKEDATE(year, 1) + INTERVAL month - 1 MONTH BETWEEN
#STARDATE - INTERVAL EXTRACT(DAY FROM #STARDATE) - 1 DAY
AND
#ENDDATE
But I have to ask you about the STARTDATE and ENDDATE criterias. What to do if STARTDATE is '2012-09-20'? Should the query return records with month = 9?
