Is there any difference in storage between MySQL, VARCHAR(1000) and TEXT (purpose: to store long strings)?

Question

Actual Phenomenon

1. Look forward to understanding the difference between VARCHAR/TEXT when storing large strings

2. How to choose the type

3. Understanding that TEXT will generate an intermediate virtual table

按照文档说明, VARCHAR(65536) --> 6KB --> 能存储足够大的字符串了

Expected Phenomenon

1. Experience in data type selection (especially large strings)

Answer 1

Greater than varchar (255) becomes tinytext
Greater than varchar (500) becomes text
Greater than varchar (20000) becomes mediumtext
