在my.cnf中具有多种数据库编码的MySQL

Question

I have a database set up to use the encoding UTF-8 multibyte-4 . This is configured in the my.cnf file:

[client]
default-character-set = utf8mb4

[mysql]
default-character-set = utf8mb4

(...)

character-set-server            = utf8mb4
collation-server                = utf8mb4_unicode_ci

I would like to add a 2nd database, let's call them DB1 and DB2 .

The problem: The application that uses this 2nd database DB2 cannot work with the encoding I have configured in my.cnf . It's a 3rd party application, so I have no possibility to change something, all I can do is modify the databse setup.

If I comment the above lines in my.cnf , the 3rd party application works, I guess it's using plain UTF-8 encoding . But now the system using the 1st database DB1 fails on encoding.

Is there a way to specify a default encoding in my.cnf for each database, separating DB1 encoding from DB2 ? Searching the internet has not shown me any solution other than using a separate/2nd MySQL installation.

Using MySQL version 5.6.x

Any hints are greatly appreciated.

Answer 1

1. Shoot that 3rd party software.

2. Have utf8 in my.cnf. Perform SET NAMES utf8mb4; in that applications that need it and that you can get to.
