How do you convert character types in MySQL?

In MySQL, you can use the CAST() function or CONVERT() function to convert data types from string to another type.

1. The value is the value to be converted.
2. Type is the target data type, which can be CHARACTER, VARCHAR, TEXT, or other character types.

Original sentence: 我明天要去图书馆找资料。

Paraphrased sentence: I need to go to the library tomorrow to look for some information.

SELECT CAST('123' AS CHAR) AS char_value;
SELECT CAST('123' AS VARCHAR(10)) AS varchar_value;
SELECT CAST('123' AS TEXT) AS text_value;

1. The value is the value that needs to be converted.
2. The type refers to the target data type, which can be character types such as CHAR, VARCHAR, TEXT, and so on.

Original: 我们需要一个能够适应快速变化的环境的解决方案。

Paraphrased: We need a solution that can adapt to rapid changes in the environment.

SELECT CONVERT('123', CHAR) AS char_value;
SELECT CONVERT('123', VARCHAR(10)) AS varchar_value;
SELECT CONVERT('123', TEXT) AS text_value;

Both the CAST() function and the CONVERT() function can be used to convert data types to character types.
