Mysql错误＃2002没有建立连接。

Question

I know previously several question had been posted on this topic. But mine is a bit difference. I already tried all the previous solution. What happened is whenever I try to select data from a specific table mysql crashes. I do work fine on all other tables but whenever I select data from that specific table it crashes even from command line. Now I am unable to mysqldump the database and also cant drop the table as it contains valuable data. Please suggest some options.

Answer 1

Use mysqlcheck to check specific table in db.

mysqlcheck -c db_name tbl_name -u root -p

provide password and it will tell you whether your table is corrupted or not.

Then you can use following command to repair table

mysqlcheck -r db_name tbl_name -u root -p 

mysqlcheck work with MyISAM and archive tables.

Answer 2

After several attempts and various suggestions from you guys I finally find a somewhat solution. It is true that the specific table was corrupted. And all other above mentioned options failed. So, I executed a query with limiting my results to 0, 100 and it works fine. Then I dump that data by using that query with mysqldump. I keep on going and changed the limit from 100, 200 and so on. Whenever I get error I simply skipped few rows. At last I had recovered almot 95% of my data which is not bad. Thanks guys for all your support.
