FlexQuery.NET.Parsers.Fql

NuGet Version

FQL (FlexQuery Language) parser for FlexQuery.NET — a SQL-inspired query syntax.

When to Use This Package

Install this package when you want to support FQL-style filter syntax in your API — a readable, SQL-inspired alternative to the native DSL. After registration, clients send FQL expressions in the filter (and related) parameters and they are parsed through the standard FlexQuery pipeline.

Installation

dotnet add package FlexQuery.NET.Parsers.Fql

Registration

Call Fql.Register() once at startup, then select the FQL syntax globally or per request:

using FlexQuery.NET;
using FlexQuery.NET.Parsers.Fql;

Fql.Register();   // registers the FQL parser in the global parser registry

// Option A: set FQL as the application-wide default syntax
FlexQueryCore.Configure(options =>
{
    options.DefaultQuerySyntax = QuerySyntax.Fql;
});

// Option B: choose FQL per request
options.QuerySyntax = QuerySyntax.Fql;

Quick Start

GET /api/users?filter=Status = 'Active' AND Age >= 18&sort=Name asc&page=1&pageSize=20

FQL Syntax Examples

Status = 'Active'
Age >= 18
Status = 'Active' AND Age >= 18
Category = 'Electronics' OR Category = 'Books'
Name CONTAINS 'john'
Status IN ('Active', 'Pending')
DeletedAt IS NULL
Age BETWEEN 18 AND 30

Features

  • Full Parameter Support — Parses filter, select, sort, aggregate, and having expressions into the FlexQuery model
  • Supported Operators=, >=, >, <=, <, !=, plus IN, NOT IN, CONTAINS, STARTSWITH, ENDSWITH, LIKE, IS NULL, BETWEEN, and collection quantifiers (ANY, ALL, COUNT)
  • Familiar KeywordsAND, OR, ASC, DESC, aggregate functions SUM, AVG, MIN, MAX, COUNT, and AS aliases
  • Integration — Registers into the global parser registry so FQL queries flow through the same validation and execution pipeline
