I would like to extract each these words and insert them in tableColumn so it would look like this

This is how my dataset looks like:
+---------+------------+-----------------+
| name |request_type| request_group_id|
+---------+------------+-----------------+
|Michael | X | 1020 |
|Michael | X | 1018 |
|Joe | Y | 1018 |
|Sam | X | 1018 |
|Michael | Y | 1021 |
|Sam | X | 1030 |
|Elizabeth| Y | 1035 |
+---------+------------+-----------------+
I want to calculate the amount of request_type's per person and count unique request_group_id's
Result should be following:
+---------+--------------------+---------------------+--------------------------------+
| name |cnt(request_type(X))| cnt(request_type(Y))| cnt(distinct(request_group_id))|
+---------+--------------------+---------------------+--------------------------------+
|Michael | 2 | 1 | 3 |
|Joe | 0 | 1 | 1 |
|Sam | 2 | 0 | 2 |
|John | 1 | 0 | 1 |
|Elizabeth| 0 | 1 | 1 |
+---------+--------------------+---------------------+--------------------------------+
What I've done so far: (helps to derive first two columns)
msgDataFrame.select(NAME, REQUEST_TYPE)
.groupBy(NAME)
.pivot(REQUEST_TYPE, Lists.newArrayList(X, Y))
.agg(functions.count(REQUEST_TYPE))
.show();
How to count distinct request_group_id's in this select? Is it possible to do within it?
I think it's possible only via two datasets join (my current result + separate aggregation by distinct request_group_id)
Example with "countDistinct" ("countDistinct" is not worked over window, replaced with "size","collect_set"):
val groupIdWindow = Window.partitionBy("name")
df.select($"name", $"request_type",
size(collect_set("request_group_id").over(groupIdWindow)).alias("countDistinct"))
.groupBy("name", "countDistinct")
.pivot($"request_type", Seq("X", "Y"))
.agg(count("request_type"))
.show(false)
I have the following table data:
+-----+---------------------+---------------------+------------+--------+------+-----------------+
| id | date_timer_off | date_timer_on | event_done | device | user | admin_email |
+-----+---------------------+---------------------+------------+--------+------+-----------------+

+-----+---------------------+---------------------+------------+--------+------+-----------------+

+-----+---------------------+---------------------+------------+--------+------+-----------------+
It needs to return only the ONE latest record per device id in the table and only if the event_done status is 'F' or in other words false.
The records must also be in the current minute that the request is being made, as the database will be queried every 20 seconds to update a list of timers.
For example if the request is made at 19:02:20 then there should be a check to check whether the date_timer_off or date_timer_on fields falls within the minute the request is made (19:02:20), thus returning the above result set.
I tried implementing the answer from this post, SQL query for returning the latest record for each ID, but was unsuccessful.
This is the current query im using in production environment but it's causing problems such as next events not firing when they should.
select * from timers_data data where data.date_timer_off >= :today AND data.date_timer_off <= :tomorrow AND data.date_timer_on >= :today AND data.date_timer_on <= :tomorrow AND data.event_done = 'F' ORDER BY data.id DESC
I also tried this:
select * from timers_data where event_done = 'F' and (date_timer_off >= now() or date_timer_on >= now()) ORDER BY id desc;
It works when running it on MySQL, but there seems to be a problem when I run it in my Spring application using Spring's JPA CrudRepository as below:
#Query(value = "select * from timers_data where event_done = 'f' and (date_timer_off >= now() or date_timer_on >= now()) ORDER BY id desc;", nativeQuery = true)
ArrayList<TimersData> findTimersForToday();
This is what I currently use in my project:
#Query(value = "select * from timers_data data where data.date_timer_off >= :today AND data.date_timer_off <= :tomorrow AND data.date_timer_on >= :today AND data.date_timer_on <= :tomorrow AND data.event_done = 'F' ORDER BY data.id DESC", nativeQuery = true)
ArrayList<TimersData> findTimersForToday(#Param("today") Date today, #Param("tomorrow") Date tomorrow);
Any help will be appreciated.
Thanks in advance
you could use a subselect with in clause based on tuple that match the device and the max(date..)
select * from timers_data data
where (device, date_timer_off) in (
select device, max(date_timer_off)
from timers_data data
where data.date_timer_off >= :today
AND data.date_timer_off <= :tomorrow
AND data.date_timer_on >= :today
AND data.date_timer_on <= :tomorrow
AND data.event_done = 'F'
group by device )
ORDER BY data.id
I have a collection of objects in MongoDB and am using Spring Data MongoDB.
My collection of entities look something like this:
--------------------------------------------
| id | snapshot | name |
--------------------------------------------
| 2 | somedate | bla |
| 2 | somedate | foo |
| 3 | somedate | bar |
| 3 | somedate | cheese |
| 6 | somedate | milk |
| 6 | somedate | lorum |
| 6 | somedate | ipsum |
| 9 | somedate | do |
| 10 | somedate | re |
| 10 | somedate | mi |
| 15 | somedate | fa |
--------------------------------------------
I want to get a list of objects where I want to have only one object of each distinct id, the object for that id should be the one with the latest date.
My result should be something like this:
--------------------------------------------
| id | snapshot | name |
--------------------------------------------
| 2 | somedate | bla |
| 3 | somedate | bar |
| 6 | somedate | milk |
| 9 | somedate | do |
| 10 | somedate | mi |
| 15 | somedate | fa |
--------------------------------------------
Is this possible in using a MongoRepository query?
I'd appreciate any help.
With the aggregation framework it's possible. Run the following aggregation operation to get the desired result:
db.collection.aggregate([
{ "$sort": { "snapshot": -1 } },
{
"$group": {
"_id": "$id",
"snapshot": { "$first": "$snapshot" },
"name": { "$first": "$name" }
}
}
])
The above native aggregation operation can then be translated to Spring Data MongoDB aggregation as:
import static org.springframework.data.mongodb.core.aggregation.Aggregation.*;
TypedAggregation<Entity> aggregation = newAggregation(Entity.class,
sort(DESC, "snapshot"),
group("id")
.first("snapshot").as("snapshot")
.first("name").as("name")
);
AggregationResults<EntityStats> result = mongoTemplate.aggregate(aggregation, EntityStats.class);

however, no matter what input I give it, it will never match anything.
Input "test":
line 1:0 extraneous input 'test' expecting {<EOF>, '{', TEXT}
Input "{}":
line 1:0 extraneous input '{}' expecting {<EOF>, '{', TEXT}
Input "{test}":
line 1:0 extraneous input '{test}' expecting {<EOF>, '{', TEXT}
Do I miss something fundamental? For some reason whatever the input, lexer just returns it as a whole token instead of lexing it. In example 2 and 3, '{' should have been matched for the rule, but nothing.
Detailed error:
enter source_stream, LT(1)={test}
enter segments, LT(1)={test}
line 1:0 extraneous input '{test}' expecting {<EOF>, '{', TEXT}
exit segments, LT(1)=<EOF>
consume [#1,6:5='<EOF>',<-1>,1:6] rule source_stream
exit source_stream, LT(1)=<EOF>
Alright, after careful thinking and deliberation, I have figured out, that what I want is impossible in lexer+parser grammar of antlr, because everything would be matched inside one of the big scoped lexer rules. Solution: split lexer and parser into two grammars and use lexer modes to do correct parsing:
Lexer grammar:
lexer grammar formatterLexer;
OPEN_RF: '{' -> pushMode(RuleMode);
CHAR_NOCURLY
: ~('{' | '}')
;
mode StringMode;
CHAR_NORIGHTB
: ~(']')
;
RIX: ']' -> popMode;
mode RuleMode;
EXLM: '!' ;
COLON: ':' ;
DOT: '.' ;
CLOSE_RF: '}' -> popMode;
LIX: '[' -> pushMode(StringMode);
LS: 's';
LT: '<';
MT: '>';
EQ: '=';
EXP: '^';
PLUS: '+';
MINUS: '-';
SPACE: ' ';
HASH: '#';
ZERO: '0';
TYPE: 'b' | 'c' | 'd' | 'e' | 'E' | 'f' | 'g' | 'G' | 'n' | 'o' | 's' | 'x' | 'X' | '%';
COMMA: ',';
CHAR: ~('{' | '}') ;

Can somebody help me solving this type of error
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
I am searching for data in linked list but when I want to insert the data into an array, it turn up to be like this:

the code:

while (current!=null ) {

return b;
}
but I will get the input if search for last data in the linked list which is 032255
this is the output:

You're going into the if statement more than twice while walking the list. If you do that, you'll go past the bounds of the b array (which can only hold two values). You should use an ArrayList instead so you can add as many items as you need.
