In a Sample Controller

using Dapper.OData.Infrastructure;
using Dapper.OData.Models;

public class OrdersController : ControllerBase
{
    private readonly IDbConnection _db;

    public OrdersController(IDbConnection db)
    {
        _db = db;
    }
    [EnableQuery]
    public IQueryable<Order> GetOrders(DbParams dbParams)
    {
        var query = "{your query}";
        var orders = _db.GetQueryableResult<Order>(query, out _, filter: dbParams.Filter, top: dbParams.Top, skip: dbParams.Skip, take: dbParams.Take, orderBy: dbParams.OrderBy);
        return orders;
    }
}

Query Data

You can use OData query options ($select, $filter, $count, $top, $skip, $orderby) as well as you can take query result directly from the database by using custom paramters as filter, top, skip, take, orderBy.

Operator Grammer

These Operators will be used to add filter for the database
