In databases, we typically use character sets to store and process Chinese character data. In MySQL, common character sets include UTF-8, GBK, and others.<\/p>\n
In the UTF-8 character set, each Chinese character is typically represented by 3 bytes. You can use the CHAR type to store Chinese characters, for example CHAR(3).<\/p>\n
In the GBK character set, each Chinese character is usually represented by 2 bytes. A CHAR type can be used to store Chinese characters, for example CHAR(2).<\/p>\n
When inserting or querying using database manipulation languages like SQL, we can directly use Chinese characters as string parameters, the database will automatically convert and store them based on the character set. For example, in MySQL, we can use the following statement to insert Chinese characters into a field of type CHAR(3):<\/p>\n
Add the value ‘\u4f60\u597d’ into the specified column of the table.<\/p>\n
When querying, we can directly use SQL statements to retrieve data, and the database will automatically convert the query results to the corresponding character set and return them. For example, in MySQL, we can use the following statement to query Chinese characters in a CHAR(3) type field:<\/p>\n
Retrieve the column_name from table_name where column_name is equal to ‘\u4f60\u597d’.<\/p>\n","protected":false},"excerpt":{"rendered":"
