How to use SQLite group_concat(X, Y) to create a single column from a JOIN?


How to use SQLite group_concat(X, Y) to create a single column from a JOIN?

wish help you to fix your issue I figured out what I was doing wrong, and it is borderline embarrassing. COLLATE NOCASE must precede the GROUP BY clause:
code :
SELECT o.ObservationGuid, o.ObservationID, o.ObservationParentTypeGuid, 
    o.ObservationTypeGuid, o.Name, o.ObservationParentName, o.GrowthStageGuid, 
    o.MorphologyTypeGuid, o.LifespanGuid, o.OrganismTypeGuid, o.ScientificName, 
    o.AgXID, o.AgGatewayID, o.Genus, o.Family, o.TaxonomicalOrder, o.Class, 
    o.Division, o.Kingdom, o.FavorableConditions, o.DescriptionSymptoms, 
    group_concat(oa.Name, '; ') 
FROM Observation o 
INNER JOIN ObservationAlias oa ON oa.ObservationGuid = o.ObservationGuid 
WHERE ObservationTypeGuid = '{E3149781-2423-4F15-8599-CB320E871284}' 
COLLATE NOCASE
GROUP BY o.ObservationGuid

I wish this help you The GROUP_CONCAT is an aggregate function and therefore needs to be applied with GROUP BY clause.
code :
SELECT
    u.id AS user_id, GROUP_CONCAT(s.subscription_id) AS subscription_ids
FROM 
    users u
    LEFT JOIN subscriptions s ON s.user_id = u.id
GROUP BY
    u.id
LIMIT 10

Does that help I have two (simplified) tables: , You need to join the TriggerSensor table 4 times
code :
SELECT programId 
FROM TriggerLogic l 
INNER JOIN TriggerSensor s1 ON l.ts1 = s1.id AND s1.active = 1
INNER JOIN TriggerSensor s2 ON l.ts2 = s2.id AND s2.active = 1
INNER JOIN TriggerSensor s3 ON l.ts3 = s3.id AND s3.active = 1
INNER JOIN TriggerSensor s4 ON l.ts4 = s4.id AND s4.active = 1

Hope that helps I have the following query , Just get all the data you want, sort it, and then aggregate it:
code :
SELECT ID,
       Name,
       group_concat(LevelName, '&/?') AS Data
FROM (SELECT Levels1.ID AS ID,
             Levels1.Name AS Name,
             FrameworkLevels1.Name AS LevelName
      FROM Levels1
      LEFT JOIN FrameworkLevels1 ON Levels1.ID = FrameworkLevels1.LevelID
      WHERE FrameworkID = :ID
      ORDER BY ...);

I think the issue was by ths following , I need to use group_concat to build a list of comma separated values but I need the values to be quoted inside single quote. How to do this? The query which I have written doesn't work for me. I have values inside column like this: , Try this, Its is working perfectly in my case:
code :
SELECT GROUP_CONCAT( DISTINCT CONCAT("'", REPLACE(user_id, "," , "','") , "'")) as listed_id FROM users

Any of those help I should start by saying I'm no PowerShell expert at all, I can cobble stuff together OK but that's about it. , You could solve this by using:
code :
$file1 = @(gc "x")
$file2 = @(gc "y")
$file3 = @(gc "z")

$combined = @()
for ($i=0; $i -lt $file1.Count; $i++) {
    $combined += $file1[$i] + ', ' + $file2[$i] + ', ' + $file3[$i]
    }

$combined | Out-File "C:\test.csv" -encoding default
