⚠️ Warning: Work In Progress (WIP) & Unstable ⚠️
This project is currently under active development. It should be considered unstable, and breaking changes may occur without notice as the API evolves. Use in production environments is strongly discouraged at this stage.
SqlArtisan: Write SQL, in C#. A SQL query builder that provides a SQL-like experience, designed for developers who value the clarity and control of direct SQL syntax.
Does this sound familiar?
- You write raw SQL strings by hand when your ORM can't handle a query.
- You build dynamic queries by stitching strings together, cluttering your core application logic.
- You write boilerplate code for
DbParameterobjects, a process prone to subtle bugs and type errors.
SqlArtisan is designed to resolve these frustrations. It lets you write that same SQL directly in C# with a SQL-like API, a clean way to build dynamic queries, and automatic parameters—like this:
bool onlyActive = true;
UsersTable u = new();
ISqlBuilder sql =
Select(
u.Id,
u.Name,
u.CreatedAt)
.From(u)
.Where(
u.Id > 0
& u.Name.Like("A%")
& ConditionIf(onlyActive, u.StatusId == 1))
.OrderBy(u.Id);
So you can focus on the query logic, not the boilerplate. That’s why SqlArtisan.

SqlArtisan | The core query builder library for writing SQL in C# with a SQL-like fluent experience. |  |  |
SqlArtisan.Dapper | Provides extension methods to seamlessly execute queries built by SqlArtisan using Dapper. |  |  |
SqlArtisan.TableClassGen | A .NET tool that generates C# table schema classes from your database, enabling IntelliSense and type-safety with SqlArtisan. |  |  |
WHERE conditions (and other query parts) using simple helpers like ConditionIf.SqlArtisan.Dapper library provides Dapper extensions that enable effortless SQL execution.Systimestamp for Oracle's SYSTIMESTAMP and CurrentTimestamp for PostgreSQL's CURRENT_TIMESTAMP. Developers should select the C# API appropriate for their target database.: or @) to suit the target DBMS. Currently, this behavior is verified for MySQL, Oracle, PostgreSQL, SQLite, and SQL Server.SqlArtisan.Dapper for seamless Dapper execution. It auto-detects the dialect from your IDbConnection to apply correct settings (like bind parameter prefixes) and provides helpful execution methods.You can install SqlArtisan and its optional Dapper integration library via NuGet Package Manager.
(Note: These packages are currently in their pre-release phase, so use the --prerelease flag when installing.)
For the core query building functionality:
dotnet add package SqlArtisan --prerelease
For seamless execution with Dapper (recommended):
dotnet add package SqlArtisan.Dapper --prerelease
Define your Table Schema Class
Create C# classes for your database tables to enable IntelliSense and prevent typos in names. You can write these manually (see example below) or generate them from an existing database with the SqlArtisan.TableClassGen tool.
using SqlArtisan;
// ...
internal sealed class UsersTable : DbTableBase
{
public UsersTable(string tableAlias = "") : base("users", tableAlias)
{
Id = new DbColumn(tableAlias, "id");
Name = new DbColumn(tableAlias, "name");
CreatedAt = new DbColumn(tableAlias, "created_at");
}
public DbColumn Id { get; }
public DbColumn Name { get; }
public DbColumn CreatedAt { get; }
}
Define your DTO Class
Create a Data Transfer Object (DTO) class. This class will be used to map the results of your SQL query.
internal sealed class UserDto(int id, string name, DateTime createdAt)
{
public int Id => id;
public string Name => name;
public DateTime CreatedAt => createdAt;
}
Build and Execute your Query
Construct your query using SqlArtisan's SQL-like API. For convenient access to entry point methods like Select() or InsertInto(), add a static using for SqlArtisan.Sql, which provides these static helper methods.
Once built, execute the query. This example uses Dapper with SqlArtisan.Dapper.
using SqlArtisan;
using SqlArtisan.Dapper;
using static SqlArtisan.Sql;
// ...
UsersTable u = new();
ISqlBuilder sql =
Select(u.Id, u.Name, u.CreatedAt)
.From(u)
.Where(u.Id > 0 & u.Name.Like("A%"))
.OrderBy(u.Id);
// Dapper: Set true to map snake_case columns to PascalCase/camelCase C# members.
Dapper.DefaultTypeMap.MatchNamesWithUnderscores = true;
// 'connection' is your IDbConnection. SqlArtisan auto-detects the DBMS
// (MySQL, Oracle, PostgreSQL, SQLite, SQL Server) & applies
// the correct bind parameter prefix (e.g., ':' or '@').
IEnumerable<UserDto> users = await connection.QueryAsync<UserDto>(sql);
Alternative: Manual Execution (Accessing SQL and Parameters)
Alternatively, access the SQL string and parameters directly for use with raw ADO.NET, other micro-ORMs, or for debugging, instead of using SqlArtisan.Dapper.
ISqlBuilder.Build() accepts an optional Dbms argument (defaulting to Dbms.PostgreSql) to specify the SQL dialect. This affects features like the bind parameter prefix (e.g., : for PostgreSQL, @ for SQL Server).
Example (Default - PostgreSQL):
UsersTable u = new();
// No args; defaults to Dbms.PostgreSql, uses ':' prefix
SqlStatement sql =
Select(u.Id, u.Name)
.From(u)
.Where(u.Id == 10 & u.Name == "Alice")
.Build();
// sql.Text is
// SELECT id, name
// FROM users
// WHERE (id = :0) AND (name = :1)
//
// sql.Parameters.Get<int>(":0") is 10
// sql.Parameters.Get<string>(":1") is "Alice"
Example (Specifying SQL Server):
UsersTable u = new();
// With Dbms.SqlServer; uses '@' prefix
SqlStatement sql =
Select(u.Id, u.Name)
.From(u)
.Where(u.Id == 20 & u.Name == "Bob")
.Build(Dbms.SqlServer);
// sql.Text is
// SELECT id, name
// FROM users
// WHERE (id = @0) AND (name = @1)
//
// sql.Parameters.Get<int>("@0") is 20
// sql.Parameters.Get<string>("@1") is "Bob"
SqlArtisan is engineered for efficient performance, primarily by minimizing heap allocations. Our core strategy is efficient buffer management using ArrayPool<T>: internal buffers, particularly for string construction, are recycled from a shared pool. This approach leads to fewer garbage collection (GC) pauses and improved application throughput.
To illustrate this, we benchmarked our ArrayPool<T>-based internal string building against common approaches using BenchmarkDotNet.

This benchmark highlights the memory efficiency of a specific internal operation within SqlArtisan by comparing it to fundamental string handling techniques. It is not intended as a direct, comprehensive performance benchmark against other SQL builder libraries, as each library has different design goals, features, and may perform optimally under different conditions or workloads.
SqlArtisan allows you to construct a wide variety of SQL queries in a type-safe and intuitive manner. Below are examples demonstrating common SQL operations and how to achieve them with SqlArtisan.
UsersTable u = new();
SqlStatement sql =
Select(
u.Id.As("user_id"),
u.Name.As("user_name"))
.From(u)
.Build();
// SELECT id "user_id",
// name "user_name"
// FROM users
UsersTable u = new();
SqlStatement sql =
Select(Distinct, u.Id)
.From(u)
.Build();
// SELECT DISTINCT id
// FROM users
// The hint below refers to this alias "u".
UsersTable u = new("u");
SqlStatement sql =
Select(Hints("/*+ INDEX(u users_ix) */"), u.Id)
.From(u)
.Build();
// SELECT /*+ INDEX(u users_ix) */ "u".id
// FROM users "u"
SqlStatement sql =
Select(CurrentTimestamp)
.Build();
// SELECT CURRENT_TIMESTAMP
SqlStatement sql =
Select(Sysdate)
.From(Dual)
.Build();
// SELECT SYSDATE FROM DUAL
UsersTable u = new();
SqlStatement sql =
Select(u.Name)
.From(u)
.Where(u.Id == 1)
.Build();
// SELECT name
// FROM users
// WHERE id = :0

Note: SqlArtisan's Set() method uses Column == Value for SQL-like assignment, unlike standard C# == (comparison). In Where() clauses, == is used for comparison as expected.

SqlArtisan also offers an alternative INSERT syntax, similar to UPDATE's Set() method, for clearer column-value pairing.
