SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Translate structured conditions into valid FilterQL expressions. This section describes how to convert field/operator/value tuples into a syntactically correct FilterQL string, enabling dynamic filtering without manual scripting.

Core Features & Use Cases

  • Maps field types and operators to FilterQL syntax using a deterministic translation matrix.
  • Supports AND/OR/NOT groupings to compose complex filters for real-world data queries.
  • Generates a slug-friendly alias for the target table and validates the final FilterQL.
  • Use Case: Build and validate filters over user data, events, or logs before deployment.

Quick Start

Provide a list of field/operator/value conditions and grouping; the tool outputs a valid FilterQL expression.

FAQPage Schema
How do I build FilterQL queries from structured conditions?▼

To build FilterQL queries, you translate structured field, operator, and value tuples into a syntactically correct FilterQL string using a deterministic translation matrix, enabling dynamic filtering without manual scripting.

What is the best way to compose AND/OR groupings for data queries in FilterQL?▼

Composing AND/OR groupings for data queries in FilterQL involves combining multiple field and operator conditions into nested logical structures, allowing you to construct complex filters for real-world user data and events.

Can I validate FilterQL syntax and generate a slug-friendly alias before deployment?▼

You can validate FilterQL syntax and generate a slug-friendly alias for the target table prior to deployment, ensuring that your constructed data filters are syntactically correct and environment-agnostic.

Does building FilterQL filters require external dependencies or specific environment setup?▼

Building FilterQL filters requires no external dependencies or specific environment setup, utilizing a dependency-light and environment-agnostic implementation to construct and validate data query conditions.

What field types and operators are supported for FilterQL condition mapping?▼

FilterQL condition mapping supports field types and operators for equality, containment, and set membership checks, mapping them to the correct syntax for filtering user data, events, or logs.
