Mysql中大小写敏感问题导致的MySql Error 1146 Tabel doen’t ex
MySql Error 1146 Tabel doen't exist,一般情况下是表不存在,或者表名写错了、权限问题。 今天遇到了这个问题,仔细核对几遍后,确认无误,又在phpMyAdmin里尝试select,可以查询出数据。又核对权限,确认该mysql用户具有所有权限。那这个错误是怎么回事呢
MySql Error 1146 Tabel doen't exist,一般情况下是表不存在,或者表名写错了、权限问题。
今天遇到了这个问题,仔细核对几遍后,确认无误,又在phpMyAdmin里尝试select,可以查询出数据。又核对权限,确认该mysql用户具有所有权限。那这个错误是怎么回事呢?查询了一些资料后,发现如果mysql引擎不对可能会造成真实存在的表却无法访问,但是发现引擎都是myisam。
这下犯愁了,错误出在哪里呢?又找了半天,仍然无果。无辜的看着这段报错代码,发呆了半天,突然发现了一个已经被我忽视的细节,详细的报错代码为 Tabel ABC doen't exist,这里的表名为大写,而数据库中的表名为abc(马冬注:只为举例,没有此表),是小写的。在phpMyAdmin用大写表名ABC尝试select,果然报错提示Tabel ABC doen't exist。
到这里,问题清楚可见,原因是一个被我忽略的问题:windows服务器下,mysql的数据表是大小写不敏感的,而linux服务器默认情况下大小写敏感。如果linux服务器要修改成大小写不敏感,可以找到/etc/my.cnf,在[mysqld]下加入一行: lower_case_table_names=1。(马冬注:lower_case_table_names默认情况下为0,及表名大小写敏感;修改为1,即大小写不敏感)。如果没有修改服务器配置的权限,那就注意出现的每一个表名都要大小写一致。
不注意小细节,往往会浪费很多时间的。细节决定成败。

MySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

Create a database using Navicat Premium: Connect to the database server and enter the connection parameters. Right-click on the server and select Create Database. Enter the name of the new database and the specified character set and collation. Connect to the new database and create the table in the Object Browser. Right-click on the table and select Insert Data to insert the data.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

You can create a new MySQL connection in Navicat by following the steps: Open the application and select New Connection (Ctrl N). Select "MySQL" as the connection type. Enter the hostname/IP address, port, username, and password. (Optional) Configure advanced options. Save the connection and enter the connection name.

Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.

Steps to perform SQL in Navicat: Connect to the database. Create a SQL Editor window. Write SQL queries or scripts. Click the Run button to execute a query or script. View the results (if the query is executed).
