Description
binary collation is shown in information_schema.collations, but it's not accepted in CREATE statements and such, e.g.
MariaDB [test]> create table t (a char(1) collate binary); |
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'binary)' at line 1 |
Maybe semantically binary collation doesn't make much sense, but not being able to parse it can cause a problem loading a dump from MySQL 8.0, as it can produce such structures:
|
8.0.28 |
MySQL [test]> create table t (a enum('a') character set binary, b char(8)) character set latin1; |
Query OK, 0 rows affected (0.194 sec) |
 |
MySQL [test]> show create table t \G |
*************************** 1. row ***************************
|
Table: t |
Create Table: CREATE TABLE `t` ( |
`a` enum('a') CHARACTER SET binary COLLATE binary DEFAULT NULL, |
`b` char(8) DEFAULT NULL |
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
1 row in set (0.001 sec) |
