SqlLinq

SqlLinq runs SQL SELECT statements over in-memory .NET collections. Queries are plain text, so they can come from a user, a config file or a saved report, and are compiled into LINQ expression trees. Queries can work with typed objects, dictionaries and dynamic objects.

The original SqlLinq was created by dkackman, and he kindly let it carry on here. Since then it has been:

  • modernized and built on .NET Standard
  • given support for more SQL syntax, clauses and functions
  • made extensible, so custom functions can be added
  • security hardened, with timeouts and cancellation, and stricter control over what can be accessed within a query
  • extended with new packages to support a time series SQL dialect (SqlLinq.TimeSeries), and unit conversions with UnitsNet (SqlLinq.Units)

Quick start

dotnet add package SqlLinq

using SqlLinq;

// Query() can select over typed objects, dictionaries, or dynamic objects
// queries support WHERE, GROUP BY, HAVING, ORDER BY, aggregates, and joins.
// "this" is the source collection.
var adults = people.Query("SELECT * FROM this WHERE Age >= 18 ORDER BY Name");

Joins

// Each entry is a table, and its key is the table's name in the query
var tables = new Dictionary<string, IEnumerable>
{
    ["people"] = people,
    ["families"] = families,
    ["cities"] = cities,
};

var members = tables.Query(
    """
    SELECT p.Name, f.Name AS Family, c.Name AS City
    FROM people p
    JOIN families f ON p.FamilyId = f.Id
    LEFT JOIN cities c ON f.CityId = c.Id
    WHERE p.Age >= 18
    """);

// Two collections can also be joined directly, as "this" and "that"
var members = people.Query<Person, Family, IDictionary<string, object>>(
    "SELECT Name, that.Name AS Family FROM this INNER JOIN that ON this.Address = that.Address",
    families);

Math functions

// Standard SQL math functions such as abs, round, power, sqrt, log and the trigonometric functions are built in
var near = people.Query("SELECT * FROM this WHERE abs(Weight - 150) <= 20");
