I am trying to get the count of unique batches in gift_code table for each campaign. The gift_code table is joined to campaign table by campaign_id.
Here is some sample data for campaign table.
--------------+--------------
|campaign_id | name |
--------------+--------------
| 1 | abc |
--------------+--------------
| 2 | xyz |
--------------+--------------
Below is some sample data for gift_code table.
--------------+------------------------+--------------+
|gift_code_id | campaign_id | batch | unique_code |
--------------+-------------+----------+---------------
| 1 | 1 | 1 | zxc23 |
--------------+-------------+----------+--------------+
| 2 | 1 | 2 | rtc26 |
--------------+-------------+----------++-------------+
| 3 | 2 | 1 | z8723 |
--------------+-------------+----------+--------------+
| 4 | 2 | 2 | h7c26 |
--------------+-------------+----------++-------------+
| 5 | 2 | 2 | rrcf6 |
--------------+-------------+----------++-------------+
| 6 | 2 | 3 | r7y28 |
--------------+-------------+----------++-------------+
| 7 | 2 | 3 | bnc26 |
--------------+-------------+----------++-------------+
$campaign = DB::table('campaign')
->select('campaign.*', DB::raw('count(gift_code.batch) as batch_count')->groupBy('gift_code.campaign_id')->groupBy('gift_code.batch'))
->leftjoin('gift_code', 'campaign.campaign_id', '=', 'gift_code.campaign_id')
->get();
My expected results are:
--------------+-------------------------+
|campaign_id | name |batch_count|
--------------+-------------+-----------+
| 1 | abc | 2 |
--------------+-------------+-----------+
| 2 | xyz | 3 |
--------------+-------------+-----------+
Try below query
$data = \DB::table('campaign as c')
->leftJoin('gift_code as gc','c.campaign_id','=','gc.campaign_id')
->select('c.*',\DB::raw('COUNT(distinct(gc.batch)) as batch_count'))
->groupBy('c.campaign_id')
->get();
I want to pivot the following table
| ID | Code | date | qty |
| 1 | A | 1/1/19 | 11 |
| 1 | A | 2/1/19 | 12 |
| 2 | B | 1/1/19 | 13 |
| 2 | B | 2/1/19 | 14 |
| 3 | C | 1/1/19 | 15 |
| 3 | C | 3/1/19 | 16 |
into
| ID | Code | mth_1(1/1/19) | mth_2(2/1/19) | mth_3(3/1/19) |
| 1 | A | 11 | 12 | 0 |
| 2 | B | 13 | 14 | 0 |
| 3 | C | 15 | 0 | 16 |
I am new to hive, i am not sure how to implement it.
NOTE: I don't want to do mapping because my month values change over time.
I need a way to avoid duplicate values from oracle join, I have this scenario.
The first table contain general information about a person.
+-----------+-------+-------------+
| ID | Name | Birtday_date|
+-----------+-------+-------------+
| 1 | Byron | 12/10/1998 |
| 2 | Peter | 01/11/1973 |
| 4 | Jose | 05/02/2008 |
+-----------+-------+-------------+
The second table contain information about a telephone of the people in the first table.
+-------+----------+----------+----------+
| ID |ID_Person |CELL_TYPE | NUMBER |
+-------+- --------+----------+----------+
| 1221 | 1 | 3 | 099141021|
| 2221 | 1 | 2 | 099091925|
| 3222 | 1 | 1 | 098041013|
| 4321 | 2 | 1 | 088043153|
| 4561 | 2 | 2 | 090044313|
| 5678 | 4 | 1 | 092049013|
| 8990 | 4 | 2 | 098090233|
+----- -+----------+----------+----------+
The Third table contain information about a email of the people in the first table.
+------+----------+----------+---------------+
| ID |ID_Person |EMAIL_TYPE| Email |
+------+- --------+----------+---------------+
| 221 | 1 | 1 |jdoe#aol.com |
| 222 | 1 | 2 |jdoe1#aol.com |
| 421 | 2 | 1 |xx12#yahoo.com |

| 899 | 4 | 2 |cvcvsd#wew.es |
| 899 | 4 | 2 |cvsd#www.es |
+------+----------+----------+---------------+
I was able to produce a result like this, you can check in this link http://sqlfiddle.com/#!4/8e326/1
+-----+-------+-------------+----------+----------+----------+----------------+
| ID | Name | Birtday_date| CELL_TYPE| NUMBER |EMAIL_TYPE|EMAIL|

If you check the data in table Email for user with ID_Person = 4 only present two of the three emails that have, the problem for this case is the person have more emails that cellphone numbers and only will present the same number of the cellphone numbers.
The result i expected is something like this.
+-----+-------+-------------+----------+----------+----------+----------------+
| ID | Name | Birtday_date| CELL_TYPE| NUMBER |EMAIL_TYPE|EMAIL|
+-----+-------+-------------+----------+----------+----------+----------------+
| 1 | Byron | 12/10/1998 | 3 | 099141021|1 |jdoe#aol.com |

This is the way that i need to present the data.
I could not understand why your query was so complex, thus, added the simple full outer join and it seems to be working:
select distinct p.id, p.name,
case when Lag(CELL) over(partition by p.id order by p.id,pe.id) = CELL then null else cell_type end as cell_type,
case when Lag(CELL) over(partition by p.id order by p.id,pe.id) = CELL then null else CELL end as CELL,
EMAIL_TYPE as EMAIL_TYPE, EMAIL as EMAIL
from person p full outer join phones pe on p.id = pe.id
full outer join emails e
on p.id = e.id and pe.cell_type = e.email_type;
Having a hive table with age column consisting of age of persons.
Have to count and display the top 3 age categories.
Ex: whether below 10, 10-15, 15-20, 20-25, 25-30, ...
Which age category appears more.
Please suggest me a query to do this.
select case
when age <= 10 then '0-10'
else concat_ws
(
'-'
,cast(floor(age/5)*5 as string)
,cast((floor(age/5)+1)*5 as string)
)
end as age_group
,count(*) as cnt
from mytable
group by 1
order by cnt desc
limit 3
;
You might need to set this parameter:
set hive.groupby.orderby.position.alias=true;
Demo
with mytable as
(
select floor(rand()*100) as age
from (select 1) x lateral view explode(split(space(100),' ')) pe
)
select case
when age <= 10 then '0-10'
else concat_ws('-',cast(floor(age/5)*5 as string),cast((floor(age/5)+1)*5 as string))
end as age_group
,count(*) as cnt
,sort_array(collect_list(age)) as age_list
from mytable
group by 1
order by cnt desc
;
+-----------+-----+------------------------------+
| age_group | cnt | age_list |
+-----------+-----+------------------------------+
| 0-10 | 9 | [0,0,1,3,3,6,8,9,10] |
| 25-30 | 9 | [26,26,28,28,28,28,29,29,29] |
| 55-60 | 8 | [55,55,56,57,57,57,58,58] |

How to query with laravel Eloquent to get the latest user education order by Level DESC
expected:
+----+-----------+----------------------+
| id | Name | Latest_Education |
+----+-----------+----------------------+
| 1 | Denny | SMP |
| 2 | Agus | SMP |
| 3 | Dini | - |
| 4 | Angel | - |
+----+-----------+----------------------+
In normal query:
select id,name ,(select E.name from education E inner join History_eductaion HE on E.id = HE.education_id where HE.userId =U.id limit 1 order by E.level DESC )latest_education from USER U
How to translate to laravel eloquent?
The quick answer is use the query builder - your query needed to be altered slightly to match the table names and columns as listed in your question:
$result = DB::table('user')
->select([
'id',
'name',
DB::raw("(select E.name from Education E inner join History_Education HE on E.id = HE.educationId where HE.userId = user.id order by E.level DESC limit 1) as latest_education")
])
->get();
