如何提高mysql关联查询 分页的查询效率
请问各位大神，我用mysql关联查询，limit进行分页 ，但是当数据过万时翻页就特别慢，请问有什么好的优化办法啊？
我的代码：
SELECT
c0.c_custnum AS cCustnum,
c0.c_username AS cUsername,
c10.cust_rank AS custRank,
jifen30.rank_name AS rankName,
c10.c_accdate AS cAccdate,
c10.c_custname AS cCustname
FROM
capf00 AS c0
LEFT JOIN capf10 AS c10 ON c0.c_custnum = c10.c_custnum
LEFT JOIN capf30 AS c30 ON (c10.c_custnum = c30.c_custnum AND c30.is_del = 'N')
LEFT JOIN capf120 ON capf120.cust_no = c10.c_custnum
LEFT JOIN jifen30 ON c10.cust_rank = jifen30.cust_rank
LEFT JOIN capf101 ON capf101.cust_no = c0.c_custnum
WHERE
capf120.create_time IS NULL
AND c0.is_del = 'N'
AND c10.is_del = 'N'
LIMIT 9500 OFFSET 10 |
