PetaPoco.SqlKata NuGet

PetaPoco is a handy micro-ORM, but the SQL builder that comes with it is extremely limited. This library lets you use SqlKata as a replacement query builder.



using (var db = new PetaPoco.Database(...))
    // Build any SqlKata query
    var query = new Query("MyTable")
        .Where("Foo", "bar");
    // Use the query in place of PetaPoco.Sql
    var records = db.Fetch<MyClass>(query.ToSql());

Note that while PetaPoco has an EnableAutoSelect feature that lets you omit the SELECT part of a query if your classes are set up correctly, SqlKata requires a table name in order to generate a query. If you try to use a Query without a table name, SqlKata will throw an InvalidOperationException when you call ToSql().

Generate from POCO

Since part of the benefit of PetaPoco is that it understands information embedded in a POCO, this library also has two extension methods to help do the same thing, letting you avoid retyping table and column names.

public class MyClass
    property int ID { get; set; }
    property string Name { get; set; }

// This is equivalent to new Query("MyClass")
// If the class has a TableName property, that will be used instead.
var query = new Query().ForType<MyClass>();

var query = new Query().GenerateSelect<MyClass>();  

Both of these methods also have overloads that can take an IMapper instance, if you don't want to use a default ConventionMapper.


Transforming a SqlKata Query into a SQL string requires a compiler. SqlKata comes with compilers for SQL Server, Postgres, MySql, and Firebird. For many simple queries, the generated SQL looks the same regardless of which compiler you use, but for certain queries the compiler will produce SQL tailored for that specific database. The compilers also know which characters to use to escape identifiers.

By default, this library uses the SQL Server compiler. If you want to use a different compiler, there are a couple of different ways you can do so.

// Specify the compiler for one SQL statement
var sql = query.ToSql(CompilerType.MySql);

// Change the default compiler for all SQL statements
SqlKataExtensions.DefaultCompiler = CompilerType.Postgres;
