In MySQL, mediumtext is a data type used for storing longer text content. It can store text data up to a maximum length of 16MB. Here are some examples of using mediumtext:

  1. Specify the mediumtext type when creating a table.
CREATE TABLE my_table (
   id INT PRIMARY KEY,
   content MEDIUMTEXT
);
  1. Insert data into a mediumtext column.
INSERT INTO my_table (id, content) VALUES (1, '这是一段较长的文本内容');
  1. Update the value of the mediumtext column:
UPDATE my_table SET content = '更新后的文本内容' WHERE id = 1;
  1. Retrieve the values from the mediumtext column.
SELECT content FROM my_table WHERE id = 1;
  1. Manipulate the mediumtext column using functions.
SELECT UPPER(content) FROM my_table WHERE id = 1;  // 将文本转换为大写
SELECT LENGTH(content) FROM my_table WHERE id = 1;  // 获取文本的长度

Please note that mediumtext can store larger text content, but if you need to store even larger text, you may want to consider using the longtext type.
