Table 'table_name' is full - How to solve MySQL error: The table is full, specific code examples are needed

When using the MySQL database, we may encounter a A common problem is that when we insert data into the table, MySQL will report an error and display the message "Table 'table_name' is full". This error is usually caused by the table's storage space being full. In this article, we will introduce several ways to solve this problem and give specific code examples.

1. Check the storage engine of the table
   First, we need to check the storage engine of the table. MySQL supports multiple storage engines, such as MyISAM and InnoDB. In some cases, choosing an inappropriate storage engine may result in a table running out of storage space. We can view the storage engine of the table through the following command:

SHOW TABLE STATUS LIKE 'table_name';

After executing the above command, detailed information about the table, including the storage engine, will be returned. If the storage engine is MyISAM, we can solve the problem by modifying the storage engine of the table to InnoDB. The specific code examples are as follows:

ALTER TABLE table_name ENGINE = InnoDB;

2. Adjust the parameter settings of the table
   Another way to solve the problem of the table being full is to adjust the parameter settings of the table. We can change the maximum storage space limit of the table by modifying the parameters in the MySQL configuration file. The specific parameter names and descriptions may vary in different versions of MySQL, but one of the common parameters is innodb_data_file_path, which controls the data file size of the InnoDB storage engine.

These parameters can be adjusted by modifying the MySQL configuration file (usually my.cnf or my.ini). Find the relevant parameter and increase its value to suit your needs. After the modification is completed, restart the MySQL service for the changes to take effect. The following is an example:

# 修改my.cnf文件
vi /etc/mysql/my.cnf

# 增加innodb_data_file_path参数的值（例如增加10G）
innodb_data_file_path = ibdata1:10G:autoextend

# 重启MySQL服务
service mysql restart

3. Clean useless data
   If the reason why the table is full is due to the presence of a large amount of useless data in the table, then we can clean up the useless data. Solve the problem. The specific method depends on the structure and usage of the table. The following is an example that shows how to delete redundant data under a specific condition in the table:

DELETE FROM table_name WHERE condition;

Please modify condition according to the actual situation to meet your needs.

4. Expand server storage space
   If none of the above methods solve the problem, the server's storage space may be full. In this case, the solution is to expand the storage space of the server. You can expand storage space by increasing hard drive capacity, cleaning up useless files, etc.

Summary:
When MySQL reports the error "Table 'table_name' is full", we can check the storage engine of the table, adjust the parameter settings of the table, clean up useless data, or expand the server storage space to solve the problem. Choose the appropriate solution based on the situation and follow the code examples to ensure that the table stores data properly.
