Statements overview
A TypeQL statement is a building block of a TypeQL pattern. Statements in TypeQL are always end with a semicolon. By default, a conjunction combines all statements in a pattern. There is a specific syntax to use for a disjunction or negation.
Simple statements
A simple statement is the smallest complete TypeQL block that can be used as a pattern in a query.
Most simple statements have three parts: Subject Predicate Object. Where the predicate is a TypeQL keyword.
Composite statements
Multiple simple statements with the same subject can be combined into a composite statement. A composite statement starts with a single subject, and multiple comma-separated simple statements with subject omitted.
See an example
$p isa person, has full-name "Kevin Morrison", has email $e;
The above example combines simple isa / isa! and has statements
to the same result without repeating the subject ($p
):
$p isa person;
$p has full-name "Kevin Morrison";
$p has email $e;
The role assignment and value assignment statements do not require a comma when added in a composite statement, as they are used without any additional keyword.
