SELECT date_trunc('month', txn_date) AS txn_month, sum(amount) as monthly_sum
FROM yourtable
GROUP BY txn_month
Is there a way to get months that have no results to show in the query?
So let's say I have :
id transDate Product Qty
1234 04/12/2019 ABCD 2
1245 04/05/2019 ABCD 1
1231 02/07/2019 ABCD 6
I also need to the the third Month returns with a 0 value
MonthYear totalQty
02/2019 6
03/2019 0
04/2019 3
Thanks,
---- UPDATE ---
Here is the final query that that gets last 24 months from the current date. with year and month ready for any charts.

Left join to a list of months:
SELECT t.txn_month,
coalesce(sum(yt.amount),0) as monthly_sum
FROM generate_series(date '2019-02-01', date '2019-04-01', interval '1 month') as t(txn_month)
left join yourtable yt on date_trunc('month', yt.transdate) = t.txn_month
GROUP BY t.txn_month
Online example
In your actual query you need to move the conditions from the WHERE clause to the JOIN condition. Putting them into the WHERE clause turns the outer join back into an inner join:
SELECT t."ItemId",
y."transactionDate" AS txn_month,
-coalesce(SUM(t."transactionQty"),0) AS "TotalSold"
FROM generate_series(date '2018-01-01', date '2020-04-01', INTERVAL '1 month') as y("transactionDate")
LEFT JOIN "ItemTransactions" AS t
ON date_trunc('month', t."transactionDate") = y."transactionDate"
AND t."ItemTransactionTypeId" = 1
AND t."ItemId" = 10606
-- this WHERE clause isn't really needed because of the date values provided to generate_series()
WHERE AND y."transactionDate" >= NOW() - INTERVAL '2 year'
GROUP BY txn_month, t."ItemId"
ORDER BY txn_month DESC;
Attendance is sorting according to date, that is fine, but I want to sort date along with the month name January should come at the bottom, and December at the top.

Attendance is sorting according to date, that is fine, but I want to sort date along with the month name January should come at the bottom, and December at the top.
I run this report Mon-Fri for the previous day's data and I am trying to figure out how to hard code TO_CHAR(TRUNC(SYSDATE-3) if today is
Monday (day the report is run) or use TO_CHAR(TRUNC(SYSDATE-1) for any other workday (mon - fri). I am assuming that this will require an IF, THEN, ELSE statement but am unsure of how to include that properly into my query.
SELECT
RRA.LAST_MODIFICATION_DATE AS "LAST MODIFICATION DATE",
TO_CHAR(TRUNC(SYSDATE-1),'DD-MON-RR') AS "DATA_DATE"
FROM PHOENIX.R_REFERRAL_ACTIVITY RRA
Where 1=1
AND RRA.LAST_MODIFICATION_DATE
BETWEEN TO_CHAR(TRUNC(SYSDATE-1),'DD-MON-RR') AND TO_CHAR(TRUNC(SYSDATE),'DD-MON-RR')
Aha; OK then, it seems that you'd need to use CASE along with TO_CHAR function which will tell you which day is "today". Have a look, see if it helps.
TEST is just a simple calendar, several days in this February. I'm removing Saturdays and Sundays (as you said you're interested in mon - fri only).

I have the following query. I need an output which would look like this
ea_month case ea_year zone_id
January 0 2013 4001
February 0 2013 4002
March 1 2013 4001
January 0 2014 4001
February 0 2014 4001
March 1 2014 4001
February 0 2014 4002
March 1 2014 4002
SELECT ea_month,CASE WHEN ea_month = (SELECT to_char(now(), 'Month')) THEN 1 ELSE 0 END,ea_year,zone_id FROM staging_ea.stg_circle_zone_billedamount_rollup
In my table I have my values for ea_month in the form of January, February, March.
After running the above query, the result-set that I am getting is something like this:
ea_month case ea_year zone_id
January 0 2013 4001
February 0 2013 4002
March 0 2013 4001
January 0 2014 4001
February 0 2014 4001
March 0 2014 4001
February 0 2014 4002
March 0 2014 4002
Can anyone suggest me where am I going wrong? Its for a PostgreSQL query.
This is caused by the to_char() function padding the month name with spaces. This can either be fixed by applying a trim() on the result or using the FM modifier in the format mask:
SELECT ea_month,
CASE
WHEN ea_month = to_char(current_date, 'FMMonth') THEN 1
ELSE 0
END,
ea_year,
zone_id
FROM staging_ea.stg_circle_zone_billedamount_rollup;

How can i do that in SQLServer2008R2. I have tried using DenseRank, RowNuber, Partitioned but all in vain.
Tru using Ntile:
--select * from #t
SELECT * ,
ROW_NUMBER() OVER ( PARTITION BY FYear, Qt ORDER BY FYear ) Qtp
from
(SELECT FYear,[Month],
NTILE(4) OVER ( PARTITION BY FYear ORDER BY FYear ) AS Qt
FROM #t) PERIOD
ORDER BY FYear ,Qt ,ROW_NUMBER() OVER ( PARTITION BY FYear, Qt ORDER BY FYear)
I propose dynamically populating a table with date values from Dec 2013 going down to the year that you like (you can alter the #COUNT_Y Variable to add more years).
SQL has some interesting datetime functions like DATEPART which can tell you which quarter a month is in etc.
** Answer changed due to question change **
DECLARE #DATES TABLE
(
xDATE DATETIME
)
DECLARE #STARTDATE DATETIME = '12-31-2013'
DECLARE #COUNT_X INT = 0
DECLARE #COUNT_X_MAX INT = 11
DECLARE #COUNT_Y INT = 0
DECLARE #COUNT_Y_MAX INT = 2
WHILE (#COUNT_Y <= #COUNT_Y_MAX)
BEGIN
SET #COUNT_X = 0
WHILE (#COUNT_X <= #COUNT_X_MAX)
BEGIN
INSERT INTO #DATES
SELECT DATEADD(MONTH, -#COUNT_X, DATEADD(YEAR,-#COUNT_Y, #STARTDATE))
SET #COUNT_X = #COUNT_X + 1
END
SET #COUNT_Y = #COUNT_Y + 1
END
SELECT * FROM
(SELECT
DATEPART(YEAR, D.xDATE) AS [YEAR],
DATEPART(MONTH, D.xDATE) AS [MONTH],
