java - MySQL通过navicat给表中的某个字段加索引，这个地方应该怎么选择呀？
为什么只有这几个 没有index？

This is the index type: normal is a normal index, unique is a unique index (columns with a unique index will have unique constraints and cannot have duplicate values, otherwise the insertion or update will fail), full text is a full-text index, only for English Strings are valid, but are invalid for Chinese (this kind of index is generally not used). Under normal circumstances, select normal.
