WHERE clause

The WHERE clause adds constraints to the patterns in a MATCH or OPTIONAL MATCH clause or filters the results of a WITH clause.

Query::where(bool|BooleanType|(bool|BooleanType)[] $expressions, string $operator = WhereClause::AND): Query

Parameters

• $expressions : A boolean expression to evaluate, or a non-empty list of boolean expression to evaluate.
• $operator : The operator with which to unify the given expressions, should be either WhereClause::OR, WhereClause::AND or WhereClause::XOR.

Relevant methods

• addExpression(bool|BooleanType $expression, string $operator): self : Add an expression to the WHERE clause, potentially unified with the existing clause using $operator.
