The editor consulted all kinds of data and sorted out a simple and easy-to-use operation method. I hope it will be helpful for you to answer the question of "what is the set type in mysql?" Next, please follow the editor to study!

Description

1. Set, much like enum, is also a string object that can contain 64 members.

Memory varies depending on the number of members. The set type can select multiple members at a time.

2. Any element can be selected from the allowable value set to be combined, so as long as the input value is within the combined range of allowable values, it can be correctly recorded in a column of type set.

An error is reported for values that are outside the allowable range. And there is a collection of duplicate members, which will be deduplicated automatically.

Example

-- create a table ts containing the fields F1 (set ()) mysql > create table ts (F1 set); mysql > insert into ts values ('aforceb`), (' aforced`), ('bPercec _ d'), (' bPercec'). At this point, the study on "what is the type of set in mysql" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
