Как вы можете видеть, что он очень неэффективен и работает по первому временному запросу по какой-либо причине. Есть ли способ упростить это, чтобы быть более эффективным и заставить значения работать для каждого запроса? Я не получил никаких ошибок.

Answer 1

Этот запрос будет вставлять строку в Branchs для каждой группы, которая не существует для $Username.

INSERT INTO Branchs (Username, Name, Image, GroupID) 
SELECT '{$gU->Username}', groups.Name, groups.Image, groups.GroupID 
FROM (
    SELECT '983872' AS GroupID, 'Temporal Investigations' AS Name, 'Temporal' AS Image 
    UNION 
    SELECT '976892', 'Tactical Command', 'Tactical' 
    UNION 
    SELECT '986292', 'Applied Sciences', 'Science' 
    ... 
    ) AS groups 
LEFT JOIN Branchs ON Branches.GroupID = groups.GroupID AND Username = '$Username' 
WHERE Branchs.GroupID IS NULL 

См Return row only if value doesn't exist для того, как LEFT JOIN работает, чтобы вернуть строки в UNION подзапроса, которые не имеют матчей в Branchs.
