Knex: 복소수 합계를 수행하는 방법

knex.raw 로 sum 에 인수를 래핑하면 작동합니까?

그렇지 않은 것 같습니다 ... 합계를 다음과 같이 변경하면 :

.sum( knex.raw( '(case when qs.score >= 60 then 1 else 0 end) AS passedCount' ) )

"val.toLowerCase가 함수가 아닙니다" 오류가 발생합니다.

( as 별칭을 추가하지 않고 빼서 괄호로 시도했지만 오류는 매번 동일했습니다)

knex 버전은 0.11.7이지만 0.11.9로 업그레이드했는데 동일한 메시지가 나타납니다.

#238에서 해결 방법을 찾았습니다. $#$ sum select 에서 knex.raw 를 수행하십시오. 지금 쓰다보니 뻔한듯...

knex( 'quiz_submissions AS qs' )
    .select( 'q.name AS quiz_name', knex.raw( 'SUM(case when qs.score >= 60 then 1 else 0 end) AS passedCount' ) )
    .avg( 'qs.score' )
    .innerJoin( 'quizzes AS q', 'q.id', 'qs.quiz_id' )
    .groupBy( 'q.name' );
