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. 3、将e:/localhost.sql导入mysql4,如mysql命令行中 source e:/localhost.sql
