情景:公司近期在将数据库从Oracle转为MySQL,由于之前在Oracle中表名是不区分大小写,因此到MySQL中就出现了找不到表的问题,经上网查询,发现在Linux下MySQL的表名是区分大小写的,但是有参数可以使其不区分大小写。具体操作如下:

一、Linux中MySQL大小写详情:
1、数据库名严格区分大小写
2、表名严格区分大小写的
3、表的别名严格区分大小写
4、变量名严格区分大小写
5、列名在所有的情况下均忽略大小写
6、列的别名在所有的情况下均忽略大小写

二、设置MySQL表名不区分大小写
1、切换到root用户
$ su - root

2、修改/etc/my.cof配置文件,,
# sed -i '/mysqld/a\lower_case_table_names=1' /etc/my.cnf

lower_case_table_names参数详解:

  • 0:区分大小写
  • 1:不区分大小写
  • 3、重启MySQL
    # service mysqld restart

    4、查看mqsql参数
    # mysql -uroot -p
    > show variables like "%case%" ;
    +------------------------+-------+
    | Variable_name          | Value |
    +------------------------+-------+
    | lower_case_file_system | OFF  |
    | lower_case_table_names | 1    |
    +------------------------+-------+
    2 rows in set (0.00 sec)

    三、其他

    在Windows中,MySQL一直都是不区分大小写的。

    When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

    Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

    InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

    Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

    The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

    Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

    MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

    Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

    MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
