How do I solve &#General Error in MySQL (XAMPP):
During database development, MySQL errors occur from time to time. Recently, I encountered a headache "General error: 1813" error while using MySQL in XAMPP environment, which prompts "Table creation failed: incorrect database definition or file corruption". After troubleshooting, I found a solution and share my experience here.
Question: General error: 1813
The error occurs when I am using Laravel 11 to migrate the database. Strangely, the same migration operation runs fine in other environments, which makes me suspect the problem is in my local XAMPP environment.
Troubleshooting steps
- Migrate file check: I first checked for syntax errors or compatibility issues with the migration file, but everything worked fine.
- MySQL Data Directory Check: I checked XAMPP's MySQL data directory (for example:
c:\xampp\mysql\data\project_name
) to find any residual files related to the table to be created. - Database permission check: I confirm that my user has sufficient database permissions.
Solution
Eventually, I found that the problem was the residual .ibd
file in the MySQL data directory. The solution is as follows:
- Problem file identification: The error is because I manually deleted a table before, but the corresponding
.ibd
file still exists in the data directory. - .ibd file location: I found a file named
tablename.ibd
inc:\xampp\mysql\data\project_name
directory (tablename
is the name of the deleted table). - .ibd file deletion: I deleted the
tablename.ibd
file directly. - MySQL restart: After deleting the file, I restarted the MySQL service through the XAMPP control panel.
- Migration retry: Run the Laravel migration again, this time it succeeded, no errors.
Experience summary
This experience taught me:
- When manually deleting MySQL tables, be sure to clean up all residual files.
- Understanding MySQL's data storage and table file management mechanisms is crucial for troubleshooting.
- Back up the database regularly, especially before performing manual operations.
Conclusion
It is frustrating to encounter mistakes like "General error: 1813", but it is also an opportunity to learn and improve. Hopefully my experience can help developers who have similar problems. Welcome to share your experience and suggestions in the comment section!

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.

MySQL is an efficient relational database management system suitable for storing and managing data. Its advantages include high-performance queries, flexible transaction processing and rich data types. In practical applications, MySQL is often used in e-commerce platforms, social networks and content management systems, but attention should be paid to performance optimization, data security and scalability.

The relationship between SQL and MySQL is the relationship between standard languages and specific implementations. 1.SQL is a standard language used to manage and operate relational databases, allowing data addition, deletion, modification and query. 2.MySQL is a specific database management system that uses SQL as its operating language and provides efficient data storage and management.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB
