我有这个错误:

Fatal error: Uncaught exception 'MySQLiQuery_Exception' with message 'Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=': select id from 'addresses' where 'shiptozip'='13000' and 'shiptostreet'='Františka Křížka'


如您所见,我正在尝试从表地址中获取ID。

mysql> show variables like 'character%';

表“地址”所在的位置还具有utf8_general_ciutf8。我想这与查询FrantiškaKřížka有关,因为其他查询也可以。 server_collat​​ion以前是latin_swedish_ci,但我想现在已经全部更改了(如上表所示)。提前致谢。

最佳答案

您可以在问题中附加以下项的“ shiptoaddress”和“ shiptozip”列的排序规则吗?

SHOW FULL COLUMNS FROM addresses;


根据您提供的证据,可能发生的情况是“ shiptoaddress”列仍具有latin1编码。设置表的编码/排序规则时,您将设置默认值。可以为单个列覆盖此默认值。

如果查询适用于where address = 'Frank'但不适用于where address = 'Františka',这是因为“Františka”不可转换为latin1。
