【 使用环境 】生产环境 or 测试环境
【 OB or 其他组件 】oceanbase mysql模式
【 文图版本 】OceanBase 4.2.1.3 (r103030022024011313-c6afef2be5748fc54b1b0159b5224ae288491424) (Built Jan 13 2024 13:36:43)
【问题描述】我有两个环境，执行下边这个sql，一个环境正常，一个环境报错[1267] [HY000]: Illegal mix of collations，去掉CAST()虽然可以正常，但是目前无法修改sql。
select T.applid from ecas_appl T
LEFT JOIN ECAS_MULTILINGUAL M
ON M.CLUB = ‘appl.name’
AND M.LANG = ‘en’
AND M.K = CAST(T.APPLID AS CHAR)
对比了两个环境的数据库版本，正常的是4.2.1.7，报错的是4.2.1.3，驱动包都是mysql.X，字符集和排序规则是一致的，希望有大佬帮忙看下~
