SqlKata - Dynamic Sql query builder for dotnet | Product Hunt

Quick Demo

SqlKata Query Builder is a powerful Sql Query Builder written in C#.

It's secure and framework agnostic. Inspired by the top Query Builders available, like Laravel Query Builder and Knex.

SqlKata has an expressive API. it follows a clean naming convention, which is very similar to the SQL syntax.

By providing a level of abstraction over the supported database engines, that allows you to work with multiple databases with the same unified API.

SqlKata supports complex queries, such as nested conditions, selection from SubQuery, filtering over SubQueries, Conditional Statements and others. Currently, it has built-in compilers for SqlServer, MySql, PostgreSQL, and Firebird.

The SqlKata.Execution package provides the ability to submit the queries to the database, using Dapper under the covers.

Checkout the full documentation on https://sqlkata.com

Installation

$ dotnet add package SqlKata
$ dotnet add package SqlKata.Execution # (optional) If you want the execution support

Quick Examples

Setup Connection

var connection = new SqlConnection("...");
var compiler = new SqlCompiler();

var db = new QueryFactory(connection, compiler)

QueryFactory is provided by the SqlKata.Execution package.

Retrieve all records

var books = db.Query("Books").Get();

Retrieve published books only

var books = db.Query("Books").WhereTrue("IsPublished").Get();

Retrieve one book

var introToSql = db.Query("Books").Where("Id", 145).Where("Lang", "en").First();

Retrieve recent books: last 10

var recent = db.Query("Books").OrderByDesc("PublishedAt").Limit(10).Get();

Include Author information

var books = db.Query("Books")
    .Include(db.Query("Authors")) // Assumes that the Books table have a `AuthorId` column
    .Get();

This will include the property "Author" on each "Book"

[{
    "Id": 1,
    "PublishedAt": "2019-01-01",
    "AuthorId": 2,
    "Author": { // <-- included property
        "Id": 2,
        "...": ""
    }
}]

Join with authors table

var books = db.Query("Books")
    .Join("Authors", "Authors.Id", "Books.AuthorId")
    .Select("Books.*", "Authors.Name as AuthorName")
    .Get();

foreach(var book in books)
{
    Console.WriteLine($"{book.Title}: {book.AuthorName}");
}

Conditional queries

var isFriday = DateTime.Today.DayOfWeek == DayOfWeek.Friday;

var books = db.Query("Books")
    .When(isFriday, q => q.WhereIn("Category", new [] {"OpenSource", "MachineLearning"}))
    .Get();

Pagination

var page1 = db.Query("Books").Paginate(10);

foreach(var book in page1.List)
{
    Console.WriteLine(book.Name);
}

...

var page2 = page1.Next();

Insert

int affected = db.Query("Users").Insert(new {
    Name = "Jane",
    CountryId = 1
});

Update

int affected = db.Query("Users").Where("Id", 1).Update(new {
    Name = "Jane",
    CountryId = 1
});

Delete

int affected = db.Query("Users").Where("Id", 1).Delete();

FAQ

How to know when a new release or a feature is available?

I announce updates on My Twitter Account, and you can subscribe to our newsletters from the website https://sqlkata.com

The database that I want is not supported. Why?

It's impossible to support all available database vendors, this is why we focus on the major ones, and we encourage you to create your own compiler for your database.

Do you accept new compilers?

Unfortunately, no, the reason is this will add overhead for the project contributors. We prefer to improve the quality of the existing compilers instead.
