SELECT TABLE_NAME AS "Tables",
round(((data_length + index_length) / 1024 / 1024), 2) "Size in MB"
FROM information_schema.TABLES
WHERE table_schema = 'kanu'
ORDER BY (data_length + index_length) DESC
LIMIT 5;
각각의 사용량은 어찌어찌 구해봤는데
solution DB에서의 각 테이블의 사용량을 %로 출력하려면 어떻게 쿼리를 작성해야 할까요...
도움 부탁드리겠습니다
SELECT TABLE_NAME AS "Table Name" , ROUND(((data_length + index_length) / 1024 / 1024), 2) AS "Table Size(MB)" , ROUND(( (data_length+index_length) / SUM( (data_length + index_length) ) OVER() )*100, 2) AS sizePercent , ROUND( SUM( (data_length + index_length) ) OVER() /1024/1024 , 2) AS "TotalSize(MB)" FROM information_schema.TABLES WHERE table_schema = 'mysql' ORDER BY (data_length + index_length) DESC
정말 감사합니다!!
