How to toggle condition in where clause - if-statement

How can I implement below logic in where clause ?
below is the scenario.
IF #include_prime = 'YES'
Then result set should contain Promo_records along with non_prime_records
IF #include_prime = 'NO'
Then result set should contain only non_prime_records
I have tried as below, for both "Yes" and "No" selection I am getting same number of records
`DECLARE
#weeks INT = 2,
#week_ending DATE = '12/03/2022',
#include_prime CHAR(3)='YES'
BEGIN
SELECT
[PRType],
[PRName],
[PRNumber],
[PROffice],
[PRStudio],
[Manager],
[WeekEndDate]
FROM Source_table
WHERE
Source_table.[WeekEndDate] BETWEEN #week_ending AND DATEADD("WEEK",CAST(#weeks AS INT),#week_ending)
AND
( ( #include_prime = 'Yes'
OR Source_table.[PRType] = 'Prime'
)
OR
( #include_prime = 'No'
AND Source_table.[PRType] <> 'Prime'
)
END`

How to create a measure that can mark two columns conditionally?

I have a table that is something like this:
ID
A
B
1H4
6S8
True
1L7
True
6T8
True
7Y8
6S2
True
True
1H1
True
6S3
True
1H9
True
True
6S0
I want to create a measure that evaluates a table to be able to conditionally (to later make conditional rules for report i.e. place color values in such cells) evaluate the cells for the following 2 conditions:
when there are values in both Column A and Column B
when there are blanks/nulls in both columns
(If both can be done in a single measure this would be ideal)
You can use a measure like this:
Background Color =
var Count_A = COUNTBLANK('Table'[A])
var Count_B = COUNTBLANK('Table'[B])
RETURN
SWITCH(TRUE();
AND(Count_A = 0; Count_B = 0); "Red";
AND(Count_A > 0; Count_B > 0); "Green";
"")
First count the blank values in each of the columns, and then return a different color, depending on both counts. Then use this measure to conditionally format the background color for each of the columns:
to get something like this:
You'll need a custom column with the logic of
Column name =
SWITCH (
TRUE (),
A = 'True'
&& B = 'True', "True",
A = ''
&& B = '', "False",
"Else goes here"
)
You'll have to change the logic if the cells without anything in them are '' or true blanks. SWITCH acts like a multiple IF statement, and Switch with TRUE() evaluates the conditions in the later steps.
You can achieve the desired result by using both custom columns and measures.
Custom Column
Column =
IF (
Table[A] <> BLANK ()
&& Table[B] <> BLANK (),
"Green",
IF ( Table[A] = BLANK () && Table[B] = BLANK (), "Red" )
)
Measure
Measure X =
IF(COUNTBLANK(Table[A]) = 0
&& COUNTBLANK(Table[B]) = 0 , "#00FF00",
IF(COUNTBLANK(Table[A]) <> 0
&& COUNTBLANK(Table[B]) <> 0 , "#FF0000")
)
After creating a measure or custom column go to conditional formatting and select background colour, and you may select either measure or column as per your choice. this will give you the desired result.

Sum of array elements in Bigquery

I have to calculate the total num of positive and (negative+null or empty values) from the table basically 2 values . I have the below query to list the negative and null and positive values .. but i want the entire count . please assist.
SELECT
ARRAY(
SELECT count(value),
FROM UNNEST(event_data_results) where REGEXP_CONTAINS(name, r'data.result.result') and ((REGEXP_CONTAINS(value, r'^-?\d+$') and SAFE_CAST(value AS INT64) <= 0 ))) AS negative_attributes,
ARRAY(
SELECT count(value) as neg_val,
FROM UNNEST(event_data_results) where value = 'null' or value='' ) AS null_attributes,
ARRAY(
SELECT count(value),
FROM UNNEST(event_data_results) where REGEXP_CONTAINS(name, r'data.result.result') and (REGEXP_CONTAINS(value, r'^-?\d+$') and SAFE_CAST(value AS INT64) > 0 )) AS positive_attributes
FROM `table` where EXISTS (SELECT 1 FROM UNNEST(event_keys) as keys , UNNEST(event_data_results) as results WHERE keys.value = "attribute")
event_keys,event_data_results , data_metrics all are repeatable struct
result should be postive : 4 negative+null :4
Below is for BigQuery Standard SQL
#standardSQL
SELECT
COUNTIF(result.value > 0) positive_attributes,
COUNTIF(result.value < 0) negative_attributes,
COUNTIF(IFNULL(result.value, 0) = 0) null_or_zero_attributes
FROM `project.dataset.table`,
UNNEST(event_data_results) AS result
WHERE EXISTS (
SELECT 1
FROM UNNEST(event_keys) AS key
WHERE key.value = "attribute"
)
you can add here whatever conditions you need
Also, if result.value is a string - you can use SAFE_CAST(result.value AS INT64) as you already do so i was not focusing on this aspect of your case

Conditional itab grouping alike HAVING clause in SQL

This is a follow-up question for this one but instead of aggregation I want to process groups based on some condition and cannot figure out the proper syntax for this. I need to exclude groups which contain documents with status "deleted", if at least one of the members of the group has this status.
I tried so far GROUP...WITHOUT MEMBERS, LOOP...FOR GROUPS, REDUCE and this is the solution I end up with
DATA(lt_valid_doc) = VALUE tt_struct(
FOR ls_valid IN VALUE tt_struct(
FOR GROUPS <group_key> OF <wa> IN lt_ilot
GROUP BY ( guid = <wa>-guid guid2 = <wa>-guid2 ) ASCENDING
LET not_deleted = REDUCE #( INIT valid TYPE t_ref_s_struct
FOR <m> IN GROUP <group_key>
NEXT valid = COND #(
WHEN valid IS NOT BOUND OR <m>-stat = 'I1040'
THEN REF #( <m> ) ELSE valid ) )
IN ( not_deleted->* ) )
WHERE ( status NE 'I1040' )
( ls_valid ) ).
 
However, this solution seems redundant to me (I1040 filter indicated twice). Is there any syntax that allows doing this in one statement (REDUCE, GROUP or whatever) without constructing nested table on-the-fly and filtering it like I am doing now?
If I use WHERE condition on all of the above statements (GROUP...WITHOUT MEMBERS, LOOP...FOR GROUPS and REDUCE) it only filters base lines for grouping not the groups itself. I need somewhat similar to HAVING in SQL.
UPDATE OK, here is real-life compilable example based on BSEG table. The task is find only unreveresed docs, i.e.to exclude all docs with reversed (XNEGP = true) lines.
TYPES: BEGIN OF t_s_bseg,
bukrs TYPE bseg-bukrs,
belnr TYPE bseg-belnr,
gjahr TYPE bseg-gjahr,
buzei TYPE bseg-buzei,
xnegp TYPE bseg-xnegp,
END OF t_s_bseg,
tt_bseg TYPE SORTED TABLE OF t_s_bseg WITH EMPTY KEY.
TYPES: t_ref_s_bseg TYPE REF TO t_s_bseg.
DATA(lt_valid_fi_doc) = VALUE tt_bseg(
FOR ls_valid IN VALUE tt_bseg(
FOR GROUPS <group_key> OF <wa> IN lt_bseg
GROUP BY ( bukrs = <wa>-bukrs belnr = <wa>-belnr gjahr = <wa>-belnr ) ASCENDING
LET not_reversed = REDUCE #( INIT valid TYPE t_ref_s_bseg
FOR <m> IN GROUP <group_key>
NEXT valid = COND #(
WHEN valid IS NOT BOUND OR <m>-xnegp = abap_true
THEN REF #( <m> ) ELSE valid ) )
IN ( not_reversed->* ) )
WHERE ( xnegp NE abap_true )
( ls_valid ) ).
Input lines
bukrs belnr gjahr buzei xnegp
1000 0100000001 2019 1
1000 0100000001 2019 2
1000 0100000003 2019 1
1000 0100000003 2019 2
1000 0100000004 2019 1
1000 0100000004 2019 2 X
Doc 0100000004 has reversed line so result should be
bukrs belnr gjahr buzei xnegp
1000 0100000001 2019
1000 0100000003 2019
Here's a solution which doesn't repeat the selection, but one question remains, is that really "better"?
The solution is based on generating an empty line if the group of lines contains one line with status 'I1040', instead of keeping the unwanted line. I'm not sure, but maybe another similar solution could keep the reference to the line (not_deleted), plus adding an auxiliary variable to know whether the reference is to keep or not. I found it more intuitive to use table indexes (INDEX INTO), but that might not work if tt_struct is a hashed table type.
I provide the code with an ABAP Unit Test so that you can quickly try it yourself.

I really hope that was some kind of personal test case, and you do not use this coding in a productive environment. If I would have to understand what you want to achieve looking only at the coding, I would hate you ;).
The key to easily solve this problem is sorting the table so that the delete condition is always in the first row of the group you want to process:
Solution1
with output of unique list:
DATA: lt_bseg TYPE STANDARD TABLE OF t_s_bseg.
SORT lt_bseg BY belnr xnegp DESCENDING.
DELETE ADJACENT DUPLICATES FROM lt_bseg COMPARING belnr.
DELETE lt_bseg WHERE xnegp = abap_true.
Solution2
with output of a non-unique list:
DATA: lt_bseg TYPE STANDARD TABLE OF t_s_bseg,
lf_prev_belnr TYPE belnr,
lf_delete TYPE char1.
SORT lt_bseg BY belnr xnegp DESCENDING.
LOOP AT lt_bseg ASSIGNING FIELD-SYMBOL(<ls_bseg>).
IF <ls_bseg>-belnr <> lf_prev_belnr.
lf_delete = <ls_bseg>-xnegp.
lf_prev_belnr = <ls_bseg>-belnr.
ENDIF.
IF lf_delete = abap_true.
DELETE lt_bseg.
ENDIF.
ENDLOOP.
the following solution might not be the prettiest one, but its simple. I's easier to remove a whole group if one member meets a condition than to add a whole group if all of them fail the condtition. Just an idea.
TYPES : BEGIN OF ty_struct,
guid TYPE string,
stat TYPE string,
END OF ty_struct,
tt_struct TYPE STANDARD TABLE OF ty_struct WITH EMPTY KEY.
DATA(lt_ilot) = VALUE tt_struct(
( guid = 'A' stat = 'I1000' )
( guid = 'A' stat = 'I1040' )
( guid = 'B' stat = 'I1020' )
( guid = 'C' stat = 'I1040' )
( guid = 'D' stat = 'I1040' )
( guid = 'D' stat = 'I1000' )).
LOOP AT lt_ilot INTO DATA(ls_ilot) WHERE stat = 'I1040'.
DELETE lt_ilot WHERE guid = ls_ilot-guid.
ENDLOOP.

Convert query to doctrine DQL

I have pretty big MySQL query for performance optimization I'm adding subqueries inside a join statement. With raw SQL all working fine. Here is the query:
SELECT
campaigns.id,
campaigns.name,
CONCAT(users.id, ' ', users.email) AS usersData,
CONCAT(campaigns.cpm, ' ', currencies.currency_code) AS cpm,
CONCAT(campaign_budgets.total_spend, ' ', currencies.currency_code) AS total_spend,
creatives.impressionsCount,
creatives.bidsCount,
creatives.winsAmount,
creatives.winsPercentage,
creatives.creativeIds
FROM campaigns
INNER JOIN users ON campaigns.user_id = users.id
INNER JOIN campaign_budgets ON campaigns.id = campaign_budgets.campaign_id
INNER JOIN currencies ON campaigns.currency_type_id = currencies.id
LEFT JOIN (
SELECT
GROUP_CONCAT(creatives.id) as creativeIds,
creatives.campaign_id,
creatives.user_id,
impressions.impressionsCount,
bids.bidsCount,
bids.winsAmount,
bids.winsPercentage
from creatives
LEFT JOIN (
SELECT
count(impressions.id) as impressionsCount,
impressions.user_id,
impressions.creative_id
from impressions
GROUP BY impressions.user_id
) as impressions ON creatives.user_id = impressions.user_id
LEFT JOIN (
SELECT
count(bids.id) as bidsCount,
SUM(CASE WHEN bids.status = 'won' THEN 1 ELSE 0 END) AS winsAmount,
SUM(CASE WHEN bids.status = 'won' THEN 1 ELSE 0 END) / COUNT(bids.id) * 100 AS winsPercentage,
bids.user_id,
bids.creative_id
from bids
GROUP BY bids.user_id
) as bids ON creatives.user_id = bids.user_id
GROUP BY creatives.campaign_id
) as creatives ON campaigns.id = creatives.campaign_id
GROUP BY campaigns.id
and I need convert it to Doctrine DQL somehow if is it possible. I've faced an issue when adding a subquery to join statement. Here is my code:
$columns = [
'campaign.id',
'campaign.name',
'CONCAT(owner.id,\' \', owner.email) as ownerEmail',
'CONCAT(campaign.cpm,\' \', currency.currencyCode) as cpm',
'CONCAT(budget.totalSpend,\' \', currency.currencyCode) as totalSpend',
'COUNT(imp.id) as impressionsCount',
'COUNT(bid.id) as totalBidsCount',
'SUM(case when bid.status = \'won\' then 1 else 0 end) as winsAmount',
'SUM(case when bid.status = \'won\' then 1 else 0 end)/COUNT(bid.id)*100 as winsPercentage',
];
$bids = $this->_em->getRepository(Bid::class)
->createQueryBuilder('bids')
->select([
'count(bids.id) as bidsCount',
'SUM(CASE WHEN bids.status = \'won\' THEN 1 ELSE 0 END) AS winsAmount',
'SUM(CASE WHEN bids.status = \'won\' THEN 1 ELSE 0 END) / COUNT(bids.id) * 100 AS winsPercentage',
'bids.userId',

])->getDQL();
$impressions = $this->_em->getRepository(Impression::class)
->createQueryBuilder('imp')
->select([
'count(imp.id) as impressionsCount',

])->getDQL();
$creative = $this->_em->getRepository(Creative::class) ->createQueryBuilder('cr')->select('cr.id')
->select([

->leftJoin(Bid::class, sprintf('(%s) as bid', $bids), Expr\Join::WITH, 'bids.id = cr.userId')
->getDQL();
$query = $this->createQueryBuilder('campaign')
->select($columns);
$query
->join('campaign.user', 'owner')
->join('campaign.campaignBudget', 'budget')
->join('campaign.currencyType', 'currency')
->leftJoin(Creative::class, sprintf('(%s) as creative', $creative), Expr\Join::WITH, 'campaign.id = cr.campaignId');
$query->groupBy('campaign.id');
$query->setMaxResults($limit);

I'm getting the error [Syntax Error] line 0, col 626: Error: Expected Doctrine\ORM\Query\Lexer::T_IDENTIFIER, got '(', issue is in adding subquery to join statement.
I would appreciate any help!!
Okay I found a solution using DBAL instead of DQL using this as a reference

SELECT Statement within IF statement

I would like to get a different result to my select statement when a parameter is 0, 1 or 2. I am not very skilled in PLSQL so I am not sure if my code would give the expected result. If i run this code i get a "SQL statement ignored" on line 3.
BEGIN
IF (:PARTYPE = 1) THEN
SELECT * FROM x
WHERE to_date(date) >= (Select to_date(sysdate)from DNV.dual)
ELSE
SELECT * FROM x
WHERE to_date(date) <= (Select to_date(sysdate)from DNV.dual)
END IF;
END;
This is just a example of my SELECT statement. Later this statement will become longer and more complex but I think this shows which results I am trying to get.
Below is a copy of my entire code but because I am not allowed to show this it has become very unreadable:
BEGIN
IF (:PARTYPE = 1) THEN
Select table1.Column1
, table1.Column2
, table1.Column3
, table1.Column4
, table1.Column5
, table1.Column6
, table1.Column7
, table1.Column8
, table1.Column9
, table1.Column10
, table1.Column11
, table1.Column12
, (Select table2.ColumnX From x2 table2 Where somthing) as "something" From x1 table1
WHERE to_date(date) >= (Select to_date(sysdate)from DNV.dual)
Order by columnX
ELSE
Select table1.Column1
, table1.Column2
, table1.Column3
, table1.Column4
, table1.Column5
, table1.Column6
, table1.Column7
, table1.Column8
, table1.Column9
, table1.Column10
, table1.Column11
, table1.Column12
, (Select table2.ColumnX From x2 table2 Where somthing) as "something" From x1 table1
WHERE to_date(date) <= (Select to_date(sysdate)from DNV.dual)
Order by columnX
END IF;
END;
I have created some new code with which i am trying to learn how a case statement works. This might help me with the code above. Unfortunately this code also doesn't work but I think it explanes my situation better. In this excample i use a separate table with data i made up. In some cases user2 is null but user1 is always filled. I want to get all items where user2 equals the parameter but if user2 is null and user1 does equal the paramter i still need that item to apear.
Select t1.user1,
t1.user2
From table t1
Where (Case
When t1.user2 IS NULL Then t1.user1 in (:PARUSER)
ELSE t1.user2 in (:PARUSER)
End Case)
Since the relational operator of the where clause depends on the partype, you cannot do the traditional CASE statement charm here. I'll have to resort with this one:
SELECT * FROM x
WHERE (to_date(date) >= (Select to_date(sysdate)from DNV.dual) AND :PARTYPE = 1)
OR (to_date(date) <= (Select to_date(sysdate)from DNV.dual) AND :PARTYPE != 1)
