I am trying create a mysql query which will return the result only if like
Today's date is between 25th and end of the month.
I couldn't find a solution or idea how to go about it.
example:
SELECT m.member_name
FROM member m, `club_name` c
WHERE m.cabinet = 1 and c.wmmr_report=0 and m.club_name=c.id and date(curdate) between ...
Thanks
Actually you need only the day, not the whole date, so you may use
SELECT m.member_name
FROM member m, `club_name` c
WHERE m.cabinet = 1 and c.wmmr_report=0 and m.club_name=c.id and DAY(NOW()) >24

I wrote a simple query, it aggregates transaction amount on each user ID for every 3 days,
select user_id, sum(tran_amt) as tot_amt from transaction_table
where tran_dt>=cast('2016-12-31' as date) - INTERVAL '2' DAY
and tran_dt<='2016-12-31'
I want to calculate 3-day aggregated transaction amount for the whole month, from 12/01 to 12/31. I know how to do it in SAS, just replace the date '2016-12-31' with a macro variable, for example &tera_dt., something like this
%do i=1 %to 31;
call symput('tera_dt', "'"||put(intnx('day','1Jan2017'd,-&i,'b'),yymmdd10.)||"'")
But how can I create this date macro variable in Teradata? Thank you!
Or put it in another way, how to create a list of variables in Teradata? I want to create a macro variable called tera_dt, this variable contains dates from '2016-10-01' to '2016-10-31' total 31 dates, then I will run my query against this macro variable tera_dt. Thanks!
I don't think you need code generation for this problem. You can join with a query against the system view sys_calendar.calendar. Something like this:
select a.user_id
, b.calendar_date as date
, sum(a.tran_amt) as tot_amt
from transaction_table a
inner join
(select calendar_date from sys_calendar.calendar
where year_of_calendar=2016 and month_of_year=12) b
on a.tran_dt>=b.calendar_date - INTERVAL '2' DAY
and a.tran_dt<=b.calendar_date
group by 1,2
I want to take all the records from a specific year.
My table is race_details and the year is a part of the date in race_date (in unix timestamp)
SELECT *
FROM race_details AS r
WHERE r.race_date=(SELECT MAX(YEAR(FROM_UNIXTIME(race_date)))
FROM race_details)
Unless there's more to the problem, I think you're overcomplicating your query:
SELECT *
FROM race_details AS r
WHERE YEAR(race_date) = 2014;
Substitute 2014 for the year to look up, and if it's a variable, remember to parameterize!
You need to compare the year of the race_date, not the whole race_date:
WHERE YEAR(race_date) = (SELECT ...)
I have a table with a list of tasks. Each task has a datetime field called "completedTime". Basically everytime a task is marked completed that field gets updated with the correct time.
Now I need to do a graph (using jQuery) for this result where the x axis is the months of the year (jan-dec) and the y axis is a number.
What is the sql query can I use so it would spit out 12 columns (Jan-Dec) with a number in each depending on how many tasks have a completedTime in that month.
I don't want to run the query below 12 times or each month.
SELECT * FROM `tasks` WHERE month(completedTime) between '02' and '03';
Any ideas?
If I understand correctly, your want it to return 12 rows (one for each month) with a count of the number of tasks.
If that is correct, then something like this should work. I added the year, which could be parametrized.
SELECT Count(*)
FROM Tasks
WHERE Year = 2011
GROUP BY Month(completedTime);
Revised with name for Month
SELECT Count(*) as total,
DateName(month, DateAdd(month, Month(completedTime), 0 ) - 1 ) as Month
FROM tasks
WHERE year(completedTime) = '2011'
GROUP BY Month(completedTime)
I have some problems when coding SQL group by week.
I have a MySQL table named order.
In this entity, there are several attributes, called 'order_id', 'order_date', 'amount', etc.
I want to make a table to show the statistics of past 7 days order sales amount.
I think first I should get the today value.
Since I use Java Server Page, the code like this:
Calendar cal = Calendar.getInstance();
int day = cal.get(Calendar.DATE);
int Month = cal.get(Calendar.MONTH) + 1;
int year = cal.get(Calendar.YEAR);
String today = year + "-" + Month + "-" + day;
then, I need to use group by statement to calculate the SUM of past 7 day total sales amount.
like this:
ResultSet rs=statement.executeQuery("select order_date, SUM(amount) " +
"from `testing`.`order` GROUP BY order_date");
I have problem here. In my SQL, all order_date will be displayed.
How can I modify this SQL so that only display past seven days order sale amount?
Besides that, I discover a problem in my original SQL.
That is, if there is no sales on that day, no results would be displayed.
OF course, I know the ResultSet does not allow return null values in my SQL.
I just want to know if I need the past 7 order sales even the amount is 0 dollars,
Can I have other methods to show the 0?
Please kindly give me advices if you have idea.
Thank you.
Usually it occurs to create with a script or with a stored procedure a calendar table with all dates.
However if you prefer you can create a table with few dates (in your case dates of last week) with a single query.
This is an example:
create table orders(
id int not null auto_increment primary key,
dorder date,
amount int
) engine = myisam;
insert into orders (dorder,amount)
values (curdate(),100),
(curdate(),200),
('2011-02-24',50),
('2011-02-24',150),
('2011-02-22',10),
('2011-02-22',20),
('2011-02-22',30),
('2011-02-22',5),
('2011-02-19',10);
select t.cdate,sum(coalesce(o.amount,0)) as total
from (
select curdate() -
interval tmp.digit * 1 day as `cdate`
from (
select 0 as digit union all
select 1 union all
select 2 union all
select 3 union all
select 4 union all
select 5 union all
select 6 union all
select 7 ) as tmp) as t
left join orders as o
on t.cdate = o.dorder and o.dorder >= curdate() - interval 7 day
group by t.cdate
order by t.cdate desc
Hope that it helps. Regards.
To answer your question "How can I modify this SQL so that only display past seven days order sale amount?"
Modify the SQL statement by adding a where clause to it:
Where order_date >= #date_7days_ago
The value for this #date_7days_ago date variable can be set before your statement:
Select #date_7days_ago = dateadd(dd,-7,getdate())
Adding that where clause to your query will return only those records which order date is in the last seven days.
Hope this helps.
You can try using this:
ResultSet rs = statement.executeQuery(
"SELECT IFNULL(SUM(amount),0)
FROM table `testing`.`order`
WHERE order_date >= DATE_SUB('" + today + "', INTERVAL 7 DAY)"
);
This will get you the number of orders made in the last 7 days, and 0 if there were none.
I'm trying to work with a database of unemployment figures from the department of labor statistics' data (available at ftp://ftp.bls.gov/pub/time.series/la/)
I need to get the last 12 months of data for any given state, which is trickier then just selecting all data from the last year as they don't always have the last few months of data in yet (right now, the last month's worth of data is November 2010).
I know which record is the newest, and the date fields I have in the database to work with are:
period_name (month name)
year
period (M01, M02, etc for January, February)
My current SQL, which pulls data from a bunch of JOINed tables, is:
USE unemploymentdata;
SELECT DISTINCT series.series_id, period_name, year, value, series.area_code,
footnote_codes, period_name, measure_text, area_text, area_type_text
FROM state_overview
LEFT JOIN series ON state_overview.series_id=series.series_id
LEFT JOIN footnote ON state_overview.footnote_codes = footnote.footnote_code
LEFT JOIN period ON state_overview.period = period.period
LEFT JOIN measure ON series.measure_code = measure.measure_code
LEFT JOIN area ON series.area_code=area.area_code
LEFT JOIN area_type ON area.area_type_code=area_type.area_type_code
WHERE area_text = 'State Name' AND year > 2009
ORDER BY state_overview.period, measure_text;
Any idea?
Since you have textual values to work with for month and year, you'll need to convert them to MySQL-formatted DATE values and can then let MySQL calculate the last year interval like so:
SELECT ... WHERE STR_TO_DATE(CONCAT(period_name,' 1 ',year),'%M %d %Y') >= DATE_SUB(STR_TO_DATE(CONCAT(most_recent_period_name,' 1 ',most_recent_year),'%M %d %Y'), INTERVAL 1 YEAR) ...;
The CONCAT() function is just building a string like "Month 1 YYYY", and the STR_TO_DATE() function is taking that string and a formatting string to tell it how to parse it, and converting it into a DATE.
Note: This query probably sucks index-wise but it should work. : )
I think a few changes to WHERE clause should do it, but for effeciency/simplcity you should also add MAX(year) to the SELECT section.
SELECT ...... MAX(year) as max_year .....
WHERE area_text = 'State Name'
AND year >= max_year - 1
AND period >= (SELECT MAX(period) WHERE year = max_year)
ORDER BY state_overview.period, measure_text;
You can store the year and month as a date, even though you don't have the day information. Just use the first of each month.
{2009, 'M1'} => 2009-01-01
{2009, 'M2'} => 2009-02-01
{2009, 'M3'} => 2009-03-01
This makes date arithmetic much easier than dealing with substrings of (potentially dirty) data. Plus (and this is big), you can index the data much more effective. As a bonus, you can now extract a lot of extra goodies using DATE_FORMAT such as month names, nr of days in month etc.
Does all states have data for all months, and is the data updated at the same time? The answer to that question dictates what query strategy you should use.
The best way is to take the strtotime ($a) of correct 1 year ago and then, when fetching the value from database then find the strtotime ($b) of the date in each result. Now
if($b < $a){
continue;
}
else {
//do something.
}
