This might help you You show data already in sequence, so there is no need to sort the data itself, which makes SUM FIELDS= with SORT a poor solution if anyone suggests it (plus code for the formatting).
MERGE with a single input file and SUM FIELDS= would be better, but still require the code for formatting.
code :
 OPTION COPY 
 OUTFIL NODETAIL, 
        REMOVECC, 
        SECTIONS=(1,7, 
                  TRAILER3=(1,7, 
                            ' ==> ', 
                            COUNT=(M10,LENGTH=3),
                            ' Records'))

it should still fix some issue I have simple table in database where are columns error_id, error_group_id and message. I want to show listing in UI which shows Message and occurrences of each error group. , You can add a COUNT in your current query:
code :
SELECT message, error_group_id, cnt
  FROM (SELECT error_id,
               message,
               error_group_id,
               rank() OVER (PARTITION BY error_group_id ORDER BY error_id) rank,
               count(*) OVER (PARTITION BY error_group_id) cnt
          FROM cc_errors)
 WHERE rank <= 1;

it helps some times I've following table: , In Oracle you can use:
code :
select * from 
  (SELECT your_column_name 
   FROM table_name 
   order by EFFECTIVE_END_DATE desc) 
where rownum=1;
SELECT *
FROM (
  SELECT your_columns, row_number() over (order by EFFECTIVE_END_DATE desc) EED
      FROM table_name)
WHERE EED = 1
 SELECT *
    FROM table_name as t1
    WHERE EFFECTIVE_END_DATE = (
        SELECT MAX(t2.EFFECTIVE_END_DATE)
        FROM table_name as t2
        WHERE t1.PERSON_ID = t2.PERSON_ID)

will help you When I want to fetch data from table it_Service_ticket. The error is , I think you just want where, not having:
code :
SELECT Assignedto, COUNT(Assignedto) as TC,
       CONCAT(AVG(STATUS = 'CLOSE') * 100, '%') as SC,
       CONCAT(AVG(STATUS = 'PENDING') * 100, '%') as PC,
       SUM(TIMESTAMPDIFF(MINUTE, Request_Date, Xetr))/60 as WH ,
       (540-SUM(TIMESTAMPDIFF(MINUTE, Request_Date, Xetr)))/60 as VH,
       COUNT(Feedback_Rate)/COUNT(Assignedto)*100 as Feed_Percent,
       SUM(Feedback_Rate)/(count(Feedback_Rate)*5)*5 as AVG_Feedback
FROM it_service_ticket st INNER JOIN
     it_problem` p
     ON st.it_problem_id = p.it_problem_id INNER JOIN
     `city_master` cm
     ON st.cityid = cm.city_id
WHERE st.xetr BETWEEN '2017-01-01 00:00:00' AND '2017-03-31 12:00:00'
GROUP BY Assignedto;

wish help you to fix your issue Beginning with MySQL 5.6, the old default behavior of allowing columns in SELECT expressions (or related ORDER BY) which did not also appear in GROUP BY when using aggregates changed to be more strict (and more like other RDBMS).
Since you have MONTH(created_at) in the ORDER BY to sort months numerically but do not have an equivalent expression in SELECT and GROUP BY, you violate MySQL's requirements for GROUP BY. The solution is to add the numeric MONTH() expression to the SELECT and the GROUP BY so the grouping can properly aggregate. This should not affect performance.
code :
def self.archives
    # Include a MONTH() expression in SELECT
    Post.unscoped.select("YEAR(created_at) AS year, MONTHNAME(created_at) AS month, MONTH(created_at) AS monthnum, COUNT(id) AS total")
        # Group with it as well
        .group("year, month, monthnum")
        # sort with the column alias
        .order("year DESC, monthnum DESC")
end
def self.archives
    Post.unscoped.select("YEAR(created_at) AS year, MONTHNAME(created_at) AS month, COUNT(id) AS total")
        # Add the expression to GROUP BY but not SELECT
        .group("year, month, MONTH(created_at)")
        .order("year DESC, MONTH(created_at) DESC")
end

seems to work fine Relating to my comment in re: preventing the duplicates from appearing in the first place - I'd guess that there are multiple rows in LivestockDetails that relate to the same species. And yet, in your query, you're not accessing any data from that table.
If you only want to report species for which you do have at least one row in LivestockDetails, use an EXISTS check instead:
code :
SELECT
    LS.id                                           AS livestock_species_id,
    LS.parent_livestock_species_id                  AS parent_livestock_species_id,
    LS.livestock_species_name_en                    AS livestock_species_name_en,  
    LSN.livestock_species_name                      AS livestock_species_name,
    LSN.description                                 AS description,
    LS.image_link                                   AS image_link

FROM LivestockSpecies                         AS LS
LEFT JOIN LivestockSpeciesName                     AS LSN
      ON LSN.livestock_species_id = LS.id AND LSN.language_id = 3          
WHERE
     EXISTS (SELECT * from LivestockDetails LD
             WHERE LD.live_stock_species_id = LS.id
             and LD.ls_vaccination_id is not null)
SELECT
    LS.id                                           AS livestock_species_id,
    LS.parent_livestock_species_id                  AS parent_livestock_species_id,
    LS.livestock_species_name_en                    AS livestock_species_name_en,  
    LSN.livestock_species_name                      AS livestock_species_name,
    LSN.description                                 AS description,
    LS.image_link                                   AS image_link

FROM (SELECT DISTINCT live_stock_species_id
      FROM LivestockDetails
      WHERE ls_vaccination_id is not null)          AS LD
INNER JOIN LivestockSpecies                         AS LS
      ON LD.live_stock_species_id = LS.id
LEFT JOIN LivestockSpeciesName                     AS LSN
      ON LSN.livestock_species_id = LS.id AND LSN.language_id = 3
