Mysql_query ("select count (*) as c from easy") or die (mysql_error (); // What error is reported

1. do not change the configuration information without any unknown consequences.
2. database services are public. any overall configuration changes will inevitably affect the use of other applications.
3. any change in configuration information will only affect the performance after the change. However, changing the data stored before the time may cause problems.
4. some people say that when ALTER is used to change a character set, the character set of the content can be converted at the same time. But at least not in mysql I use.

We recommend that you restore the original configuration file to solve the problem.
It is correct to set the character set of a field and use the set names command in a timely manner.
Because your project is likely to run in an existing environment. If the program depends on external configurations, the consequences can be imagined.
