*_bin: 表示的是binary case sensitive collation,也就是说是区分大小写。 *_ci: case insensitive collation,不区分大小写。 ④ 如果建表时校对规则未用*_bin,则可直接修改字段的属性。 altertabletest3 modify namevarchar(20) collate utf8_bin; 四、总结 只要在创...
In my.cnf add "lower_case_table_names=1" under [mysqld] section. For the changes to take effect, we should restart mysql daemon. If we are changing this feature after we have created some uppercase tables which have upper case filenames in the filesystem, we should make sure that...
CaseInsensitiveCaseSensitiveWindowsCaseSensitive 在状态图中,初始状态是大小写不敏感,当lower_case_table_names的值为1时进入大小写不敏感的状态;当lower_case_table_names的值为2时,进入大小写敏感的状态;对于Windows系统,即使值为2,也会被强制转换为小写。 结论 MySQL 8表名不区分大小写的特性可以方便开发人员在...
*_bin: 表示的是binary case sensitive collation,也就是说是区分大小写。 *_ci: case insensitive collation,不区分大小写。 示例如下: mysql> CREATE TABLE Test1(Id int ,Name VARCHAR(20) COLLATE utf8mb4_bin ); mysql> INSERT INTO Test1(id,name) VALUES(2,'Bb'); #查询 mysql> SELECT id,name ...
set-variable=lower_case_table_names=0(0:大小写敏感;1:大小写不敏感) 最后重启一下MySql服务即可。 方法二: 一种方法是可以设置表或行的collation,使其为binary或case sensitive。在MySQL中,对于Column Collate其约定的命名方法如下: *_bin: 表示的是binarycasesensitive collation,也就是说是区分大小写的*_cs...
but the data directory is on a case-insensitive file system which is an unsupported combination. Please consider either using a case sensitive file system for your data directory or switching to a case-insensitive table name mode.)这才发现mysql最新的版本,这个表名大小写敏感跟着文件系统走,改不了...
Name comparisons are not case-sensitive. This works only on file systems that are not case-sensitive! InnoDB table names and view names are stored in lowercase, as for lower_case_table_names=1. Scenario One: Create table when lower_case_table_names=0 and drop when lower_case_table_names=...
Notice:Column, index, stored routine, and event names are not case sensitive on any platform, nor are column aliases. 下面在测试环境为Red Hat Enterprise Linux Server release 5.7, MySQL 5.6.20: mysql>showvariableslike'lower_case_table_names'; ...
