FlexQuery.NET.Dapper

NuGet Version

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 GenerationSqlTranslator 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 DetectionISqlDialectResolver can detect dialect from the DbConnection
  • Entity Mapping — Fluent entity-to-table mapping via DapperQueryOptions.Entity<T>()
  • 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
