How to solve the issue of garbled characters when inserting data in MySQL.

Inserting data in MySQL showing garbled characters is often caused by incorrect character set settings in the database. To solve this problem, you can try the following methods:

1. Check the database character set settings: First, make sure the database’s character set is configured correctly by using the following command to view the database’s character set settings:

show variables like 'character_set_database';

If the character set is not configured correctly, you can change the database character set using the following command:

alter database your_database character set utf8;

1. Check the character set settings of the table: To verify if the character set settings of the table are correct, you can use the following command to check the table’s character set settings.

show create table your_table;

To change the character set of a table, you can use the following command if the character set of the table is incorrectly set.

alter table your_table convert to character set utf8;

1. Check the connection character set configuration: Ensure that the correct character set is used when connecting to the database. You can set the character set when connecting to the database, for example by adding character set settings in the connection string.

jdbc:mysql://localhost:3306/your_database?useUnicode=true&characterEncoding=UTF-8

The issue of displaying garbled characters in MySQL data insertion can be resolved by inspecting and setting the character sets for the database, tables, and connections using the above methods.
