“selection set”可以造什么句，selection set造句

The Mate constraint type is also needed for the next selection set, however, you use the Flush solution type to modify the constraint.

Locking is also performed so that rows cannot be inserted in a way that would change the selection set used in other transaction.

All the rows in the database table that are affected by the current transaction will be locked; no other transaction can insert, delete or update a row in the selection set.
