I've got a sql where I need to constantly look back 4 days. This code would run once a week so I need to look 7 days back. My where clause is set stationary and looks between two dates, However I need it to look back 7 days all the time.
Here is a snippet of my code:

specifically, I'm needing to change this snippet here:
WHERE
to_date(gtrips.trip_date) >= "2020-12-11" --Needs to be rolling 7 days
AND
to_date(gtrips.trip_date) <= "2020-12-17"
I tried converting the date but it's falling over in Hive. Can someone assist with this?
You can use current_date:
WHERE
to_date(gtrips.trip_date) >= date_sub(current_date, 7) --7 days back
AND
to_date(gtrips.trip_date) <= current_date
Or pass current date as a -hiveconf parameter:
WHERE
to_date(gtrips.trip_date) >= date_sub(to_date('${hiveconf:current_date}'), 7) --7 days back
AND
to_date(gtrips.trip_date) <= to_date('${hiveconf:current_date}')
I need help. Currently below scripts will return more than 1 row if seafarer have more than 1 visa.
However, I need it to return single row, despite how many visa does seafarer have.

I have 2 queries that are almost identical. One executes in just a couple of minutes, the other either times out or takes over 20 minutes. Researched but didn't find online a comparison between Inner join vs Having (only find Where vs Inner Join, or Where vs Having). I would like to understand why one works a lot faster than the other. The 1st query is the one that works OK, the 2nd is the query that is not working properly :

This is my 1st post on the forum. Usually I was able to find what I needed - but to tell the truth - I am not really sure how to ask a correct question to the issue. Therefore, please accept my apologies if there already is an answer on the forum and I missed it.
I am running the following code in an Oracle database via Benthic Software:
SELECT
T1."REGION"
, T1."COUNTRY"
, T1."IDNum"
, T1."CUSTOMER"
, T1."BUSSINESS"
, T3."FISCALYEARMONTH"
, T3."FISCALYEAR"
, SUM(T4."VALUE")
,"HISTORICAL_PURCHASE_FLAG"
FROM
"DATABASE"."SALES" T4
, "DATABASE"."CUSTOMER" T1
, "DATABASE"."PRODUCT" T2
, "DATABASE"."TIME" T3
WHERE
T4."CUSTOMERID" = T1."CUSTOMERID"
AND T4."PRODUCTID" = T2."PRODUCTID"
AND T4."DATEID" = T3."DATEID"
AND T3."FISCALYEAR" IN ('2016')
AND T1."COUNTRY" IN ('ENGLAND', 'France')
GROUP BY
T1."REGION"
, T1."COUNTRY"
, T1."IDNum"
, T1."CUSTOMER"
, T1."BUSSINESS"
, T3."FISCALYEARMONTH"
, T3."FISCALYEAR"
;
This query provides me with information on transactions. As you can see above, I would like to add a column named "HISTORICAL_PURCHASE_FLAG".
I would like the query to take CUSTOMER and FISCALYEARMONTH. Then, I would like to check if there are any transactions registered for the CUSTOMER, up to 2 years in the past.
So lets say I get the following result:
LineNum REGION COUNTRY IDNum CUSTOMER BUSSINESS FISCALYEARMONTH FISCALYEAR VALUE HISTORICAL_PURCHASE_FLAG
1 Europe ENGLAND 255 Abraxo Cleaner Co. Chemicals 201605 2016 34,567.00
2 Europe FRANCE 123 Metal Trade Heavy 201602 2016 12,500.00
3 Europe ENGLAND 255 Abraxo Cleaner Co. Chemicals 201601 2016 8,400.00
LineNum 1 shows transaction for Abraxo Cleaner Co. registered on 201605. And LineNum 3 is also for Abraxo Cleaner Co. but registered on 201601. What I would need the query to do, is to flag LineNum 1 as 'Existing'. Because there was a previous transaction registered.
On the other hand, LineNum 3 was the first time transactions was registered for Abraxo Cleaner Co. so the line would be flagged as 'New'.
To sum up, I would like for each row of data to be treated individually. And to check if there are any previous records of data for CUSTOMER & FISCALYEARMONTH - 24 months.
Thank you in advance for the help.
You can use LAG function:
SELECT
"REGION"
, "COUNTRY"
, "IDNum"
, "CUSTOMER"
, "BUSSINESS"
, "FISCALYEARMONTH"
, "FISCALYEAR"
, SUM("VALUE")
, MAX(CASE WHEN to_date(prev_fym,'YYYYMM') >= ADD_MONTHS (to_date("FISCALYEARMONTH",'YYYYMM'), -24) THEN 'Existing'
ELSE NULL END) "HISTORICAL_PURCHASE_FLAG"
FROM
(
SELECT
T1."REGION"
, T1."COUNTRY"
, T1."IDNum"
, T1."CUSTOMER"
, T1."BUSSINESS"
, T3."FISCALYEARMONTH"
, T3."FISCALYEAR"
, T4."VALUE"
, LAG ("FISCALYEARMONTH", 1) OVER (PARTITION BY T1."IDNum" ORDER BY T3."FISCALYEARMONTH" DESC) prev_fym
FROM
"DATABASE"."SALES" T4
, "DATABASE"."CUSTOMER" T1
, "DATABASE"."PRODUCT" T2
, "DATABASE"."TIME" T3
WHERE
T4."CUSTOMERID" = T1."CUSTOMERID"
AND T4."PRODUCTID" = T2."PRODUCTID"
AND T4."DATEID" = T3."DATEID"
AND T1."COUNTRY" IN ('ENGLAND', 'France')
AND T3."FISCALYEAR" IN ('2014','2015','2016')
)
WHERE "FISCALYEAR" IN ('2016')
GROUP BY
"REGION"
, "COUNTRY"
, "IDNum"
, "CUSTOMER"
, "BUSSINESS"
, "FISCALYEARMONTH"
, "FISCALYEAR"
;
Using a simplified "input" table... You can use the LAG() analytic function and a comparison condition to populate your last column. I assume your fiscalyearmonth is a number - if it is a character field, wrap fiscalyearmonth within TO_NUMBER(). (It would be much better if in fact you stored these as true Oracle dates, perhaps date 2016-06-01 instead of 201606, but I worked with what you have currently... and took advantage that in numeric format, "24 months ago" simply means "subtract 200").
with inputs (linenum, idnum, fiscalyearmonth) as (
select 1, 255, 201605 from dual union all
select 2, 123, 201602 from dual union all
select 3, 255, 201601 from dual union all
select 4, 255, 201210 from dual
)
select linenum, idnum, fiscalyearmonth,
case when fiscalyearmonth
- lag(fiscalyearmonth)
over (partition by idnum order by fiscalyearmonth) < 200
then 'Existing' else 'New' end as flag
from inputs
order by linenum;
LINENUM IDNUM FISCALYEARMONTH FLAG
---------- ---------- --------------- --------
1 255 201605 Existing
2 123 201602 New
3 255 201601 New
4 255 201210 New
Another solution might be to outer Join "DATABASE"."SALES" T4 a second time as T5, wilter the fiscal year via WHERE to < t4.FiscalYear-2. If the Column is NULL, the record is new, if the outer join results in a value, the record is historic.
You can achieve using row_number() function as below... modify as per your need...I assumed 2 years (means previous 24 months from sysdate ).
You can run the sub-queries separately to check how its working.
Select
"REGION"
,"COUNTRY"
,"IDNum"
,"CUSTOMER"
,"BUSSINESS"
,"FISCALYEARMONTH"
,"FISCALYEAR"
,"VALUE"
, ( case when ( TXNNO = 1 or TOTAL_TXN_LAST24MTH = 0 ) then 'New' else 'Existing' end ) as "HISTORICAL_PURCHASE_FLAG" -- if no txn in last 24 month or its first txn then 'new' else 'existing'

Below the query I created to get certain itemnumbers, qty ordered and price and others from the database. The problem is that sometimes an order doesn't contain 20 itemsnumbers but only 2. Now my question is if it's possible to fill the spaces with other itemnumbers random from the DB. It doesn't need to be correct because it's just for testing.
So can anybody help?

Without being able to really test this, you might try something like this. Replace the inline view 'x' with this:
FROM (
WITH q AS (
SELECT LEVEL r, TO_CHAR(TRUNC(dbms_random.value*1000,0)) item
, TRUNC(dbms_random.value*100,0) qty_ordered
, TRUNC(dbms_random.value*10,2) unit_cost
FROM dual CONNECT BY LEVEL <= 20
)
SELECT COALESCE(x1.r, q.r) r, supplier, order_no, written_date
, COALESCE(x1.item, q.item) item
, COALESCE(x1.qty_ordered, q.qty_ordered) qty_ordered
, COALESCE(x1.unit_cost, q.unit_cost) unit_cost
FROM (SELECT ROW_NUMBER() OVER (PARTITION BY oh.order_no ORDER BY ol.item ASC) r
, oh.supplier
, oh.order_no
, oh.written_date
, ol.item
, ol.qty_ordered
, ol.unit_cost
FROM ordhead oh JOIN ordloc ol ON oh.order_no = ol.order_no
WHERE NOT unit_cost IS NULL) x1 RIGHT JOIN q ON x1.r = q.r
) x
GROUP BY x.order_no
The WITH clause will give you a table with 20 rows of random data. Outer join that with your old 'x' data and you will be guaranteed 20 rows of data. You might not need to cast the item as a varchar2 depending on data. (N.B., I finally found a query that it makes sense to use a RIGHT JOIN with. See this SO question)
I'm not quite sure what you're trying to do with the GROUP BY and MAX stuff? In the future it would be helpful to condense your examples into something others can easily test, a minimal case that gets your point across.
I also incorporated #Kevin's good suggestion to use ROW_NUMBER instead of RANK.
very difficult to understand...
i think you might be ok if you put a 0 instead of null in the price values...
, max(decode(r,18,x.unit_cost,0)) PRICE18
and
, max(decode(r,20,x.qty_ordered,0)) QTY20
then at least the math should work.
Rank will not guarantee a sequential count of the items in the groups there, may be gaps when you have several rows with the same value.

I think you need to use row_number
