FlexQuery.NET.Dapper

SQL generation and async execution for Dapper.

When to Use This Package

Install this package when your application uses Dapper instead of Entity Framework Core. FlexQuery.NET.Dapper translates QueryOptions into parameterized, dialect-aware SQL and executes it directly via DbConnection.

Installation

dotnet add package FlexQuery.NET.Dapper

Registration

using FlexQuery.NET.Dapper;
using FlexQuery.NET.Dapper.Dialects;

builder.Services.AddFlexQueryDapper(options =>
{
    options.UseSqlServer();
});

Or configure options per-query:

options.Dialect = new PostgreSqlDialect();
options.CommandTimeoutSeconds = 60;

Quick Start

using FlexQuery.NET.Dapper;
using FlexQuery.NET.Dapper.Dialects;

[HttpGet("users")]
public async Task<IActionResult> GetUsers([FromQuery] FlexQueryParameters parameters)
{
    await using var connection = new SqlConnection(connectionString);

    var result = await connection.FlexQueryAsync<User>(parameters, options =>
    {
        // Or register the dialect globally using AddFlexQueryDapper()
        options.Dialect = new SqlServerDialect(); 
        
        options.AllowedFields = new HashSet<string> { "Id", "Name", "Email" };
    });

    return Ok(result);
}

Features

SQL Generation — SqlTranslator produces parameterized, injection-safe SQL
Dialect Support — SQL Server, PostgreSQL, MySQL, SQLite via ISqlDialect
Flat Projection — Deep select paths (e.g., Orders.Total) become LEFT JOIN with flattened aliases
Optional Auto-Dialect Detection — ISqlDialectResolver can detect dialect from the DbConnection
Mapping Registry — Custom entity-to-table mapping via IMappingRegistry
Diagnostics — Pass Action<FlexQueryExecutionConfig> to observe pipeline stages

Known Limitations

Filtered includes (EF Core navigation property expansion) are not supported
Navigation property projection requires flat projection mode
Some aggregate functions may vary by dialect

FlexQuery.NET — Core query engine
FlexQuery.NET.AspNetCore — ASP.NET Core integration
FlexQuery.NET.EntityFrameworkCore — Alternative provider for EF Core
