HomeDatabaseMysql Tutorial在Navicat for MySQL工具中大小写敏感的情况下表名称会出现变小_MySQL

Navicat

  (1)        问题描述

                1﹚ 在Navicat for mysql 修改过表名之后表在后续的跟进中会把表名在未知情况下变成小写的.

                   2﹚ 在大小写敏感情况下,对字段中该大写的字母修改之后发现说表已经存在,

                  3﹚ 我们数据库设置是大小写敏感的,所以导致有些查询语句会无法查询,数据库同步无法用工具实现同步,造成比较大的困难

                 4﹚ 我们在数据库设计中对数据库配置设置为大小写不明感,然后再把配置修改回来,发现数据库中表名也会紧跟着变成小写,所以造成的困难是比较大的.

  ﹙2﹚             操作

                 1﹚ 唯一想到的实现的办法一就是通过数据库文件进行修改,这样修改风险性比较大,而且耗时太久,在文件量大的时候会无法修改

                 2﹚ 还有一个办法就是在不追求改动的情况下,在数据库同步的时候修改配置,然后同步,同步完成后把名称修改回来,这样可以实现,但是不能存根底上解决

                3﹚ 在读了一下mysql性能调优和架构设计中突然想到了一点,我们的额数据库存贮位置可以在配置文件中找到,然后找到数据库存贮位置中的表设计修改表名为小写的.frm文件,重新打开数据库发现表名是大小写敏感了,数据库同步的时候发现一切是可以正常同步的没有错误

  ﹙3﹚             解决:

                 按照操作三进行修改数据库中的表名称,可以正常的实现

MySQL: String Data Types and CollationsMySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

MySQL: What length should I use for VARCHARs?MySQL: What length should I use for VARCHARs?May 09, 2025 am 12:06 AM

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
