Restriction and AND - SQL
Restriction is available via the WHERE operator, and so it is in SQL. However, by Example showing how a certain simple restriction can be expressed using JOIN and a relation literal. It is useful to show SQL's counterpart of that example, giving the student ids of students named Boris.

SELECT DISTINCT StudentId
FROM IS_CALLED NATURAL JOIN (VALUES ('Boris')) AS T(Name)
