A conceptual, declarative query language for TypeDB that enables polymorphic queries and intuitive data modeling.
TypeQL is the query language for TypeDB, a polymorphic database system. It provides a conceptual, declarative syntax for defining database schemas and querying data, enabling intuitive expression of complex relationships and polymorphic operations. It solves the problem of cumbersome, low-level querying in complex data systems by offering a high-level language that mirrors natural thought patterns.
Developers and data engineers working with TypeDB who need to define schemas and query highly connected, polymorphic data. It's particularly valuable for teams building systems with complex relationships, inheritance hierarchies, and evolving data models.
Developers choose TypeQL for its intuitive, declarative syntax that reduces the learning curve and maintenance burden compared to traditional query languages. Its unique selling point is full variablization and polymorphism, allowing queries to adapt automatically to schema changes without refactoring.
TypeQL: Built for systems, not records

Based on TypeDB's conceptual model, TypeQL uses near-natural language that mirrors how we think about data, making complex queries easier to express, as shown in the examples with entity-relationship patterns.
Users define queries without worrying about execution strategy; TypeDB's query planner handles optimization, reducing the need for manual tuning, as emphasized in the README's declarative approach.
Any concept, including types, can be variablized, enabling powerful parametric and polymorphic queries that automatically adapt to schema changes without refactoring, demonstrated in the polymorphic query examples.
Underpinned by a powerful type system that ensures safety and consistency in database applications, preventing common errors and maintaining data integrity, as highlighted in the built-for-consistency feature.
Complex patterns can be broken down into atomic constraints and composed in any order with guaranteed validity, promoting modular and maintainable code, as illustrated in the step-by-step query composition examples.
TypeQL is designed exclusively for TypeDB, meaning queries and schemas are not portable to other database systems, limiting flexibility and increasing dependency on a single vendor.
The README notes that TypeQL query builders and ORM code generators are still in development, indicating a lack of mature third-party tools and integrations, which can hinder productivity.
Compared to SQL, TypeQL has a smaller user base and community, resulting in fewer learning resources, tutorials, and support options, which can slow down development and troubleshooting.
