When SET Xact_abort is off, sometimes only the Transact-SQL statement that produces the error is rolled back, and the transaction continues to process. If the e

The relationship between the user table (User_set) and the E-mail table (email_set): Each user can have multiple different e-mail addresses, and for users, e-mail is a collection, which can be expressed in the user's entity class by defining the properties of a collection type.
Create two corresponding tables:
Email_set:
CREATE TABLE Email_set (
ID int (one) not NULL,
address varchar (+) NOT null
) Engine=innodb default charset= Gbk
User_set:
CREATE TABLE User_set (
ID int (one) not NULL auto_i
