復(fù)制代碼


gpt給的優(yōu)化建議是下面這個(gè)，如果正確的話(huà)，具體優(yōu)化哪個(gè)文件夾呢?
  1. 當(dāng)CURDATE()轉(zhuǎn)為索引字段時(shí)，MySQL無(wú)法直接利用dateline索引，而需要對(duì)全表的dateline列進(jìn)行函數(shù)運(yùn)算后才能做比較，查詢(xún)效率低。

  3. 如果dateline是以時(shí)間戳存儲(chǔ)的，可以把條件改為 dateline = UNIX_TIMESTAMP(CURDATE())，這樣可以避免全表轉(zhuǎn)換。

原貼不能編輯了，補(bǔ)充一下gpt的優(yōu)化方案！這個(gè)dateline優(yōu)化代碼在哪個(gè)文件了呢？
  1. 不要在WHERE條件中對(duì)字段進(jìn)行函數(shù)操作。在你的SQL語(yǔ)句中，你使用了FROM_UNIXTIME(dateline, ＇%Y-%m-%d＇) = CURDATE()進(jìn)行比較，由于需要對(duì)每一行的dateline執(zhí)行FROM_UNIXTIME函數(shù)，這將導(dǎo)致索引無(wú)法使用，并需要全表掃描。建議將這部分修改為dateline >= UNIX_TIMESTAMP(CURDATE()) AND dateline < UNIX_TIMESTAMP(DATE_ADD(CURDATE(), INTERVAL 1 DAY))。

你不能說(shuō)插件有問(wèn)題或者代碼有問(wèn)題，畢竟這是一個(gè)正常的sql，但是考慮使用場(chǎng)景
不是牽涉到pre_forum_thread就有問(wèn)題，而是這個(gè)sql是否在合適的場(chǎng)景使用，比如你慢日志的sql，如果頻繁的調(diào)用，那么就可能造成數(shù)據(jù)庫(kù)的服務(wù)壓力

打個(gè)通俗的比方：圖書(shū)館有10000本數(shù)（你的數(shù)據(jù)條目數(shù)），10個(gè)管理員（性能上限），每個(gè)人進(jìn)圖書(shū)館都要查詢(xún)下去年2月份買(mǎi)的書(shū)單，如果管理員沒(méi)有每個(gè)月購(gòu)書(shū)的目錄，而書(shū)上面貼了購(gòu)書(shū)時(shí)間，是不是得一本本看，100個(gè)人進(jìn)來(lái)，是不是得排隊(duì)
作者: 科站網(wǎng)    時(shí)間: 2024-2-23 13:25
所以最好的是找到這段sql調(diào)用的地方，優(yōu)化下，可以做緩存
繼續(xù)用上面的比方，如果第一個(gè)人進(jìn)來(lái)，查到書(shū)的目錄，緩存下來(lái)，第二個(gè)人只要看緩存數(shù)據(jù)就行了，而不用從頭查一次

緩存已經(jīng)弄了，沒(méi)啥效果，這段sql調(diào)用的我感覺(jué)就是dateline這里！但是不知道是哪個(gè)文件！

不是你這樣推斷的!

mingkong 說(shuō)的已經(jīng)很清楚了, 先找到 具體是哪個(gè)文件的 哪些代碼, 在 執(zhí)行這些sql操作;

然后 想辦法優(yōu)化這些sql語(yǔ)句,
sql語(yǔ)句 沒(méi)優(yōu)化空間了, 就優(yōu)化服務(wù)器……或者是 限制使用……

做好以上兩項(xiàng), 還影響嚴(yán)重的話(huà), 就只能干掉對(duì)應(yīng)的功能了……
