A developer defines an entity class Student.java and uses the following code to construct a teaching table:
Entity(tableName="student",ignoredColums =["ignoredColumn1"," ignoredColumn2", indices =(@Index(value =("firstName." ,"lastName",name="name_index", unique = true)))
Public class User extends OrmObject{
@PrimaryKey(autoGenerate= true)
Private Integer userld;
Private String firstName;
Private String lastName;
Private int age;
Private double balance;
Private int ignoredColumnl;
Private int ignoredColumn2;
}
Which of the following descriptions of this code is wrong?
- lgnoredColumns indicates that the field does not need to be added to the attributes of the student table
- lndices creates a composite index name_index for the firstName and 1astName fields
- The name of the data table is student
The index value of the - composite index name_index is not unique
