I am looking to add 'if else' condition within a where clause, but not sure how would I do it. Looking at the below table set, I am trying to filter the results where the query would extract all the Product line subtypes and add a condition only when the [Product Line Subtype] = 'Marine'. When it is Marine, then it should consider only two combinations of Section and Profit Code while omitting other combinations.
Combination 1 When Prod line Subtype = Marine then Section = Inland and Profit Code = Builders
Combination 2 When Prod line Subtype = Marine then Section = Ocean and Profit Code = Stocks
My actual table has larger sets of distinct combinations than showed in the below table when Prod line Subtype = Marine, but I just want to filter only the above two combinations to my results set. Any help would be much appreciated!
Main table
+--+------------------+-------------+-----------------+
| |Prod line Subtype | Section | Profit Code |
+--+------------------+-------------+-----------------+
| | Marine | Inland | Builders |
| | Marine | Ocean | Stock |
| | Property | General | Transport |
| | Energy | Source | Others |
| | Property | General | Transport |

Expected Results
+--+------------------+-------------+-----------------+
| |Prod line Subtype | Section | Profit Code |
+--+------------------+-------------+-----------------+
| | Marine | Inland | Builders |
| | Marine | Ocean | Stock |
| | Property | General | Transport |
| | Energy | Source | Others |
| | Property | General | Transport |
| | Energy | Source | Transport |
+--+------------------+-------------+---------------- +
My query attempt:
select *
from #Step1
where c1.row_ord = 1
and c1.[Prod Line Subtype] = 'Marine' AND (
(c1.[Section] = 'Inland' AND c1.[Profit Code] = 'Builder')
OR (c1.[Section] = 'Ocean' AND c1.[Profit Code] = 'Stock')
)
What about:
Select * from [Your table]
Where ([Prod line Subtype]<>'Marine' Or
(Section='Inland' And [Profit Code]='Builders') Or
(Section='Ocean' And [Profit Code]='Stocks')
)
Can omit the [Prod line Subtype]='Marine' from or conditions

I'm fairly new to pivot tables. How could I write a query to translate and summarize the data?
Thanks!
If your Oracle version is 11.1 or higher (which it should be if you are a relatively new user!) then you can use the PIVOT operator, as shown below.
Note that the result of the PIVOT operation can be given an alias (I used p) - this makes it easier to write the SELECT clause.
I assumed the name of your table is geological_data - replace it with your actual table name.
select p.*
, open_pit_tonnage + underground_tonnage as combined_tonnage
, open_pit_au_gt + underground_au_gt as combined_au_gt
, open_pit_au_oz + underground_au_oz as combined_au_oz
from geological_data
pivot (sum(tonnage) as tonnage, sum(au_gt) as au_gt, sum(au_oz) as au_oz
for area in ('Open Pit' as open_pit, 'Underground' as underground)) p
;
Conditional aggregation is a simple method:
select Property, Zone, Category,
max(case when area = 'Open Pit' then tonnage end) as open_pit_tonnage,
max(case when area = 'Open Pit' then Au_gt end) as open_pit_Au_gt,
max(case when area = 'Open Pit' then Au_oz end) as open_pit_Au_ox,
max(case when area = 'Underground' then tonnage end) as Underground_tonnage,
max(case when area = 'Underground' then Au_gt end) as Underground_Au_gt,
max(case when area = 'Underground' then Au_oz end) as Underground_Au_ox
from t
group by Property, Zone, Category
SQL Server PIVOT operator is used to convert rows to columns.
Goal is to turn the category names from the first column of the output into multiple columns and count the number of products for each category
This query reference can be taken into account for you above table:
SELECT * FROM
(
SELECT
category_name,
product_id,
model_year
FROM
production.products p
INNER JOIN production.categories c
ON c.category_id = p.category_id
) t
PIVOT(
COUNT(product_id)
FOR category_name IN (
[Children Bicycles],
[Comfort Bicycles],
[Cruisers Bicycles],
[Cyclocross Bicycles],
[Electric Bikes],
[Mountain Bikes],
[Road Bikes])
) AS pivot_table;
Consider the following sample table("Customer") with these records

I have these records and many more records dumped into SQL database and wanted to find top 10 similar customer based on the attribute value. For example customer-1 and customer-19 have atleast one column value matching .i.e "att-a-7" so the output should give me 2 customer-id's or top similar customer that are customer-1 and customer-19.
P.S - there can be one or more columns similar across rows.
I'm using windowing technique to find top 10 similar customer and im not sure if I'm correct.
following is my approach I used in my query :
row_number() over (partition by att-a, att-b,..,att-j order by customer-id) as customers
is this correct. ?
Given a set (lat, long) I am trying to find the maximum speed using "max_speed" and street type using "highway".
I have loaded my database (Postgres and Postgis) as follows:
$ osm2pgsql -c -d gis --slim -C 50000 /var/lib/postgresql/data/germany-latest.osm.pbf
The closest related question I could find was How to query all shops around a certain longitude/latitude using osm-postgis?. I have taken the query, and plugged in a (lat, long) that I found in google maps for the city center of Munich (as the post was also related to city center Munich and I have the map for Germany). The result turns up empty.
gis=# SELECT name, shop FROM planet_osm_point WHERE ST_DWithin(way ,ST_SetSrid(ST_Point(48.137969, 11.573829), 900913), 100);
name | shop
------+------
(0 rows)
Also when looking into the planet_osm_nodes, which contains (lat, long) pairs directly, I end up with no results:
gis=# SELECT * FROM planet_osm_nodes WHERE ((lat BETWEEN 470000000 AND 490000000) AND (lon BETWEEN 100000000 AND 120000000)) LIMIT 10;
id | lat | lon | tags
----+-----+-----+------
(0 rows)
I verified the data is in my database:
gis=# SELECT COUNT(*) FROM planet_osm_point;
count
---------
9924531
(1 row)
and
gis=# SELECT COUNT(*) FROM planet_osm_nodes;
count
-----------
288597897
(1 row)
So ideally, my question would be
Q: How can I find the "max speed" and "highway" given a set (lat, lon)
alternatively, my questions is:
Q: How do I get the query from the other stack overflow post to work?
My best guess is that I need to transform my (lat, lon) in some way, or that I simply have the wrong data for whatever reason.
Edit: added sample data as requested:
gis=# SELECT * FROM planet_osm_point LIMIT 1;

Geometry in PostGIS has a different ordering of (lat long) first is going longitude then latitude.
Also if you want to transform a point from one SRID to another use st_transfrom(), not ST_SetSrid.
ST_Transform relly transform your data from one coordinates system to another.
select st_astext(st_transform(ST_SetSrid(ST_Point(11.573829,48.137969), 4326),900913))
ST_SetSrid - just change SRID for the object.
select st_astext((ST_SetSrid(ST_Point(11.573829,48.137969),900913)
So, you have to change your SQL that way
SELECT name, shop
FROM planet_osm_point
WHERE ST_DWithin(way,st_transform(ST_SetSrid(ST_Point(11.573829,48.137969), 4326),900913), 100);
I'm considering aerospike for one of our projects. So I currently created a 3 node cluster and loaded some data on it.
Sample data
ns: imei
set: imei_data
+-------------------+-----------------------+-----------------------+----------------------------+--------------+--------------+
| imsi | fcheck | lcheck | msc | fcheck_epoch | lcheck_epoch |
+-------------------+-----------------------+-----------------------+----------------------------+--------------+--------------+

| "413012628090023" | "2016-09-21 10:06:49" | "2017-09-16 13:54:40" | "13dc0b080011044917006100" | 1474432609 | 1505550280 |
| "413010130130320" | "2016-12-29 22:05:07" | "2017-10-09 16:17:10" | "13d20b080011044917003100" | 1483029307 | 1507546030 |

Then I created a secondary index on lcheck_epoch using AQL since I want to query based on date.
create index idx_lcheck on imei.imei_data (lcheck_epoch) NUMERIC
+--------+----------------+-----------+-------------+-------+--------------+----------------+-----------+
| ns | bin | indextype | set | state | indexname | path | type |
+--------+----------------+-----------+-------------+-------+--------------+----------------+-----------+
| "imei" | "lcheck_epoch" | "NONE" | "imei_data" | "RW" | "idx_lcheck" | "lcheck_epoch" | "NUMERIC" |
+--------+----------------+-----------+-------------+-------+--------------+----------------+-----------+
When I execute
select imsi from imei.imei_data where idx_lcheck=1476165806
I'm getting
Error: (204) AEROSPIKE_ERR_INDEX
Please explain.
You're using the index name, not the bin name, in your query. Try this:
SELECT imsi FROM imei.imei_data WHERE lcheck_epoch=1476165806
Or
SELECT imsi FROM imei.imei_data WHERE lcheck_epoch BETWEEN 1490000000 AND 1510000000
Just a note, you can do much more complex queries using predicate filtering through several of the language clients (Java, C, C#, Go). For example the PredExp class of the Java client (see examples.)
I am casting a real to an int and a float to an int and comparing the two like this:
where
cast(a.[SUM(PAID_AMT)] as int)!=cast(b.PAID_AMT as int)
but i am still getting results where the two are equal. for example:
+-----------+-----------+------------+------------+----------+
| accn | load_dt | pmtdt | sumpaidamt | Bpaidamt |
+-----------+-----------+------------+------------+----------+

+-----------+-----------+------------+------------+----------+
here is the full query:
select
a.accn,
a.load_dt,
a.pmtdt,
a.[SUM(PAID_AMT)] sumpaidamt,
sum(b.paid_amt) Bpaidamt
from
[MILLENNIUM_DW_DEV].[dbo].[Millennium_Payment_Data_May2011_July2012] a
join
F_PAYOR_PAYMENTS_DAILY b
on
a.accn=b.ACCESSION_ID
and
a.final_rpt_dt=b.FINAL_REPORT_DATE
and
a.load_dt=b.LOAD_DATE
and
a.pmtdt=b.PAYMENT_DATE
where
cast(a.[SUM(PAID_AMT)] as int)!=cast(b.PAID_AMT as int)
group by
a.accn,
a.load_dt,
a.pmtdt,
a.[SUM(PAID_AMT)]
what am i doing wrong? how do i return only records that are NOT equal?
I don't see why there is an issue.
The query is returning the sum of the payments in b (sum(b.paid_amt) Bpaidamt). The where clause is comparing individual payments. This just means that there is more than one payment.
Perhaps your intention is to have a HAVING clause instead:
having cast(a.[SUM(PAID_AMT)] as int)!=cast(sum(b.PAID_AMT) as int)
You can do a round and a cast statement.
cast(round(sumpaidamt,2) as money) <> cast(round(Bpaidamt,2) as money)
