mysql5的sql文件导入到mysql4的方法

1、将mysql5里导出的sql文件导入到mysql5中。
2、用mysqldump -uroot -p1234 --opt --compatible=mysql40 -a -re:\localhost.sql
--compatible=name参数描述如下：
--compatible=name change the dump to be compatible with a given mode. by
default tables are dumped in a format optimized for
mysql. legal modes are: ansi, mysql323, mysql40,
postgresql, oracle, mssql, db2, maxdb, no_key_options,
no_table_options, no_field_options. one can use several
modes separated by commas. note: requires mysql server
version 4.1.0 or higher. this option is ignored with
earlier server versions.

source e:\localhost.sql
