같은 데이터를 어떤 것을 가져하려고 노력하지만 난하려고합니다 원하는 group_concat 이상 사용 (모든 서버에서 제한은 1024kb입니다.) 그래서 파일 사이에 사용 구분 기호를 가져오고 싶습니다. ","

이 내 쿼리

SELECT 
        cat_id as cat__id , 
        cat_name,(
        SELECT count(tickets.tic_id) from tickets INNER JOIN cats on(tickets.tic_cat = cats.cat_id) where tickets.tic_cat = cat__id group by tickets.tic_cat limit 1 
       ) as "count(tickets)",(
        SELECT (LENGTH(GROUP_CONCAT(tickets.tic_files)) - LENGTH(REPLACE(GROUP_CONCAT(tickets.tic_files) , "," , "")) + 1) FROM tickets 
        INNER join cats on (tickets.tic_cat = cats.cat_id) 
        WHERE tickets.tic_files != "" AND tickets.tic_cat = cat__id 
         LIMIT 1 
        ) as "count(ticket_files)",(

해결

Answer 1

그것은이 같은 문자열에서 발행 수의 수를 계산 할 수 있습니다 :

SELECT LENGTH(GROUP_CONCAT(DISTINCT tic_files SEPARATOR ",")) - LENGTH(REPLACE(GROUP_CONCAT(DISTINCT tic_files SEPARATOR ",") , ',' , '')) + 1 AS `TIC File Count` 

이것은 열의 총 길이를 취한 다음 검색하려는 모든 문자를 공백으로 대체 한 후 열의 길이를 빼서 작동합니다.

그래서 56a4sdasd.txt,jkasd5ass.jpg이 56a4sdasd.txtjkasd5ass.jpg이 될 것이고, 리턴 값은 1이 될 것입니다. 단지 1을 더하고 구분 기호 주위에 총 문자열 수를 갖게됩니다.
