In MySQL, what is the maximum length of the varchar type? We will find that the varchar length is 65535 for the varchar data type, that is, 65532 bytes of data can be stored, is that true? Let's take a look. 1. Restrictions Field restrictions

1. Restriction rules The limits of a field have the following rules when the field is defined: A) storage limits The varchar field is to store the actual content separately from the clustered index, where the content begins with 1 to 2 bytes
