火車頭採集器使用‘匯入資料庫’形式釋出資料到帝國CMS資料庫的過程（原創）適用於ECMS7.2
網上有不少相關的資訊，有部分文章已經相當不錯了，但是還是並不能正確的寫入記錄，或者說只能相容比較老的版本(具體是之前哪個版本，還並不知曉)（本文描述的內容，是可以適用於EmpireCMS7.2的），比如有一種說法，只需要修改：phome_ecms_news(一次insert，一次update），phome_ecms_news_data_1（一次insert）兩張表，現實是如果只操作這兩張表，一般都會出現如下的錯誤：
而且在刪除資料的時候，一樣會報一些資料庫方面的錯誤。這種情況下唯一的辦法就是檢視清楚，每一條新錄入的資料，在錄入過程中，到底對資料庫操作了什麼？
開啟SQL語句日誌功能，可以檢視在執行新增一條新資訊的時候，資料庫到底做了哪些操作，
SET GLOBAL log_output = 'TABLE';SET GLOBAL general_log = 'ON';（記得之後要關閉，不然會產生太多不必要的日誌檔案）
執行完成後，發現新增記錄過程中，所有執行過的SQL語句如下：
mysql> SELECT * from mysql.general_log ORDER BY event_time DESC;
+----------------------------+------------------------------+-----------+-----------+--------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| event_time | user_host | thread_id | server_id | command_type | argument |
+----------------------------+------------------------------+-----------+-----------+--------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

我們剔除掉一些SELECT語句和無用的系統相關的SET語句，只留下update和insert語句，最後經過排查，剩下這些操作還是有用的，然後在使用下面語句生成的記錄上進行刪除，修改操作，都是正常的，因此可以斷定，只需要對如下表進行操作， 就可以完成新增記錄的操作。
1.insert into phome_ecms_news_index(classid,checked,newstime,truetime,lastdotime,havehtml) values('2','1','1539238638','1539238707','1539238707','1'); 2.insert into phome_ecms_news_data_1(id,classid,keyid,dokey,newstempid,closepl,haveaddfen,infotags,writer,befrom,newstext) values('4','2','','1','0','0',0,'','','','<p> content content content content content content content content content content content content</p>') 3.insert into phome_ecms_news(id,classid,ttid,onclick,plnum,totaldown,newspath,filename,userid,username,firsttitle,isgood,ispic,istop,isqf,ismember,isurl,truetime,lastdotime,havehtml,groupid,userfen,titlefont,titleurl,stb,fstb,restb,keyboard,title,ftitle,newstime,titlepic,smalltext) values('4','2','0','0',0,'0','2018-10-11','','1','admin','0','0','0','0','0',0,'0','1539238707','1539238707','1','0','0','','','1','1','1','keyword','title','fubiao','1539238638','','content desc') 4.update phome_enewsclass set allinfos=allinfos+1,infos=infos+1 where classid='2' limit 1 5.update phome_ecms_news set filename='4',titleurl='/youhua/seo/2018-10-11/4.html' where id='4'6.update phome_enewsfile_1 set pubid='1000010000000002',classid='2',id='2',cjid=0 where cjid='1539236638' 7.update phome_enewspublic_update set lastnuminfo=lastnuminfo+1,lastnuminfotb='|1,40|',todaynuminfo=todaynuminfo+1 limit 18.insert into phome_enewsdolog(username,logip,logtime,enews,doing,pubid,ipport) values('admin','::1','2018-10-11 13:45:07','AddNews','classid=2<br>id=2<br>title=title','1000010000000002','63863')
使用過程中發現：update phome_enewsfile_1 set pubid='1000010000000002',classid='2',id='2',cjid=0 where cjid='1539236638' 這個其實也是一條無效操作，因為這個表始終是空的，後續會不會在某些時候有用，暫時還不得而知，先去掉這條語句，後來經過研究發現這條記錄是用於儲存附件的， 因為暫時沒有附件，所以可以先不處理這條記錄。 最後一條是日誌記錄，經過測試發現日誌是可以不寫的，不會影響操作的正常進行，所以可以先忽略。
這樣最後有用的剩下六條：1.insert into phome_ecms_news_index(classid,checked,newstime,truetime,lastdotime,havehtml) values('2','1','1539238638','1539238707','1539238707','1');2.insert into phome_ecms_news_data_1(id,classid,keyid,dokey,newstempid,closepl,haveaddfen,infotags,writer,befrom,newstext) values('4','2','','1','0','0',0,'','','','<p> content content content content content content content content content content content content</p>')3.insert into phome_ecms_news(id,classid,ttid,onclick,plnum,totaldown,newspath,filename,userid,username,firsttitle,isgood,ispic,istop,isqf,ismember,isurl,truetime,lastdotime,havehtml,groupid,userfen,titlefont,titleurl,stb,fstb,restb,keyboard,title,ftitle,newstime,titlepic,smalltext) values('4','2','0','0',0,'0','2018-10-11','','1','admin','0','0','0','0','0',0,'0','1539238707','1539238707','1','0','0','','','1','1','1','keyword','title','fubiao','1539238638','','content desc')4.update phome_enewsclass set allinfos=allinfos+1,infos=infos+1 where classid='2' limit 15.update phome_ecms_news set filename='4',titleurl='/youhua/seo/2018-10-11/4.html' where id='4'6.update phome_enewspublic_update set lastnuminfo=lastnuminfo+1,lastnuminfotb='|1,40|',todaynuminfo=todaynuminfo+1 limit 1
我們只需要在匯入資料庫時做好這些操作就可以了。
insert into phome_ecms_news_index(classid,checked,newstime,truetime,lastdotime,havehtml) values('2','1','1539238638','1539238707','1539238707','1');insert into phome_ecms_news_data_1(id,classid,keyid,dokey,newstempid,closepl,haveaddfen,infotags,writer,befrom,newstext) values('4','2','','1','0','0',0,'','','','<p> content content content content content content content content content content content content</p>')insert into phome_ecms_news(id,classid,ttid,onclick,plnum,totaldown,newspath,filename,userid,username,firsttitle,isgood,ispic,istop,isqf,ismember,isurl,truetime,lastdotime,havehtml,groupid,userfen,titlefont,titleurl,stb,fstb,restb,keyboard,title,ftitle,newstime,titlepic,smalltext) values('4','2','0','0',0,'0','2018-10-11','','1','admin','0','0','0','0','0',0,'0','1539238707','1539238707','1','0','0','','','1','1','1','keyword','title','fubiao','1539238638','','content desc')update phome_enewsclass set allinfos=allinfos+1,infos=infos+1 where classid='2' limit 1update phome_ecms_news set filename='@@IDENTITY',titleurl=concat('/youhua/seo/2018-10-11/',@@IDENTITY,'.html') where [email protected]@IDENTITYupdate phome_enewspublic_update set lastnuminfo=lastnuminfo+1,lastnuminfotb='|1,40|',todaynuminfo=todaynuminfo+1 limit 1
為了讓文章ID唯一，我們需要使用@@IDENTITY識別符號，來實現唯一標識的傳遞，那麼就不能直接用上面的順序來進行資料庫填寫，因為@@IDENTITY（@@identity是表示的是最近一次向具有identity屬性(即自增列)的表插入資料時對應的自增列的值，是系統定義的全域性變數。）insert into phome_ecms_news_index(classid,checked,newstime,truetime,lastdotime,havehtml) values('2','1','1539238888','1539238888','1539238888','1');insert into phome_ecms_news(id,classid,ttid,onclick,plnum,totaldown,newspath,filename,userid,username,firsttitle,isgood,ispic,istop,isqf,ismember,isurl,truetime,lastdotime,havehtml,groupid,userfen,titlefont,titleurl,stb,fstb,restb,keyboard,title,ftitle,newstime,titlepic,smalltext) values('6','2','0','0',0,'0','2018-10-11','','1','admin','0','0','0','0','0',0,'0','1539238888','1539238888','1','0','0','','','1','1','1','keyword','title','fubiao','1539238888','','content desc')update phome_ecms_news set filename='6',titleurl=concat('/youhua/seo/2018-10-11/6.html') where id=6insert into phome_ecms_news_data_1(id,classid,keyid,dokey,newstempid,closepl,haveaddfen,infotags,writer,befrom,newstext) values('6','2','','1','0','0',0,'','','','<p> content content content content content content content content content content content content</p>')update phome_enewsclass set allinfos=allinfos+1,infos=infos+1 where classid='2' limit 1;update phome_enewspublic_update set lastnuminfo=lastnuminfo+1,lastnuminfotb='|1,43|',todaynuminfo=todaynuminfo+1 limit 1;
把部分內容替換成系統標識以後，如下所示：insert into phome_ecms_news_index(classid,checked,newstime,truetime,lastdotime,havehtml) values('2','1','[系統時間戳]','[系統時間戳]','[系統時間戳]','1')
insert into phome_ecms_news(id,classid,ttid,onclick,plnum,totaldown,newspath,filename,userid,username,firsttitle,isgood,ispic,istop,isqf,ismember,isurl,truetime,lastdotime,havehtml,groupid,userfen,titlefont,titleurl,stb,fstb,restb,keyboard,title,ftitle,newstime,titlepic,smalltext) values(@@IDENTITY,'2','0','0',0,'0','2018-10-11','','1','admin','0','0','0','0','0',0,'0','[系統時間戳]','[系統時間戳]','1','0','0','','','1','1','1','keyword','[標籤:標題]','','[系統時間戳]','','');
update phome_ecms_news set filename='@@IDENTITY',titleurl=concat('/youhua/seo/2018-10-11/',@@IDENTITY,'.html') where [email protected]@IDENTITY;
insert into phome_ecms_news_data_1(id,classid,keyid,dokey,newstempid,closepl,haveaddfen,infotags,writer,befrom,newstext) values(@@IDENTITY,'2','','1','0','0',0,'','','','[標籤:內容]');
update phome_enewsclass set allinfos=allinfos+1,infos=infos+1 where classid='2' limit 1;
update phome_enewspublic_update set lastnuminfo=lastnuminfo+1,lastnuminfotb=concat('|1,',lastnuminfo,'|'),todaynuminfo=todaynuminfo+1 limit 1;
具體操作如下圖：
通過測試釋出，檢視釋出後的情況，可以看到已經發布的記錄：
更新記錄，生成html檔案後，開啟如下圖所示：
這樣火車頭的內容釋出以資料庫形式釋出，到這裡就結束了。上面這五條sql語句，是資料庫釋出必備的，整個過程斷斷續續除錯了幾天，發現火車頭採集器跟帝國的文章釋出相當繁瑣， 而且帝國CMS的釋出好像用的人不是很多，寫出來共享給大家說不定有用，過程相當不易，覺得有用的朋友們點個贊。。。
