SELECT CONCAT("mysqldump -uroot -p ", TABLE_SCHEMA, " ", TABLE_NAME, " >> ", TABLE_SCHEMA, ".bak.sql")

还可以把生成的shell命令保存在文件里(但必须是本地文件夹,或者客户端所在的主机文件夹, 也或者 mapped 的server文件夹,并且文件不存在)
SELECT CONCAT("mysqldump -uroot -p ", TABLE_SCHEMA, " ", TABLE_NAME, " >> ", TABLE_SCHEMA, ".bak.sql")
FROM INFORMATION_SCHEMA WHERE TABLE_NAME LIKE ‘Country%‘
INTO OUTFILE ‘C:/sample.sh‘;
