導入50G文件到mysql,而後再倒入sqlserver

--導入大文件50G文件到mysql
一、修改配置
innodb_flush_log_at_trx_commit=0

二、導入時的注意事項
set autocommit=1;
show variables like 'autocommit';
set names utf8;
source f://file.sql;

三、過程當中查看導入的數量
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED ;
SELECT count(id) FROM TABLE_NAME ;
COMMIT ;

select table_schema,table_name,table_type,table_rows
from information_schema.tables where table_name='tm_work_material'

四、sqlserver 導入mysql

五、關鍵步驟

 

六、超大文件處理EmEditor工具超級牛逼,能夠免費試用1個月

七、導入過程當中，檢查數據的編碼和導入的數量
use cdmp;

SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED ;
SELECT * FROM tm_work_material limit 10;
SELECT * FROM tm_workorder limit 10;
SELECT * FROM tm_workorder_hour limit 10;
COMMIT ;

select table_schema,table_name,table_type,table_rows
from information_schema.tables where table_name in('tm_work_material','tm_workorder','tm_workorder_hour');

八、導入過程
