All Implemented Interfaces:

Expression

public final class WhereClause

extends AbstractConditionalClause

The WHERE clause of a query consists of a conditional expression used to select objects or values that satisfy the expression. The WHERE clause restricts the result of a select statement or the scope of an update or delete operation.

BNF: where_clause ::= WHERE conditional_expression
