Key Points of MySQL4 to MySQL5 Transfer

Source: Internet
Author: User

Example: transfer data from MySQL4 to MySQL5. The data format is utf8.

1. Export the data table structure first. First create a database in MySQL5, set the encoding to utf8_general_ci, and then import mysql5.

2. Export the data, use UltraEdit to open it, and add set names UTF8 to the top;

3. Command import: MySQL-h localhost-u root-p database name <File Name>

PS: Do not use NotePad to open and add set names UTF8. Because notepad will add an unknown symbol to the file header, this symbol is still invisible.
