Examples

The following code example demonstrates how to use the OrWhere method to add an OR condition to the WHERE clause. In this example, the OR condition is specified by the variable for another WHERE clause.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Appeon.ApiDoc.Models.School;
using SnapObjects.Data;

namespace Appeon.ApiDoc.IQueryAndOrBuilderExamples
{
    public class OrWhereExample
    {
        private SchoolContext _context;
        
        public OrWhereExample(SchoolContext dataContext)
        {
            // Sets Data Context
            _context = dataContext;
        }

        public async Task<int> Example7()
        {
            // Get a QueryBuilder.
            var Builder = _context.SqlModelMapper.GetQueryBuilder<Person>();
            
            // Defines a SqlWhereCondition.
            var sqlwherebuilder = SqlBuilder.Where("PersonID", SqlBinaryOperator.Equals,
                                    SqlBuilder.Parameter<int>("id"));
            var sqlwherebuilder2 = SqlBuilder.Where("PersonID", SqlBinaryOperator.Equals,
                                    SqlBuilder.Parameter<int>("id2"));
                                    
            Builder.Where(sqlwherebuilder)
                   .OrWhere(sqlwherebuilder2);
                   
            var result = (await Builder.LoadAsync(1, 2)).ToList();
            
            foreach (var person in result)
            {
                Console.WriteLine("PersonID:    {0}", person.PersonID);
                Console.WriteLine("FirstName:   {0}", person.FirstName);
                Console.WriteLine("LastName:    {0}", person.LastName);
                Console.WriteLine();
            }
            
            return result.Count;
            
            /*This code produces the following output:
            
                PersonID:    1
                FirstName:   Kim
                LastName:    Abercrombie
                
                PersonID:    2
                FirstName:   Gytis
