Examples

The following code example demonstrates how to use the OrWhereValue method to add an OR condition to the WHERE clause. In this example, the OR condition specifies that the Title value must be equal to "Physics".

using SnapObjects.Data;
using System;

namespace Appeon.ApiDoc.ISqlWhereAndOrExamples
{
    public class OrWhereValueExample
    {
        private readonly SchoolContext _context;

        public OrWhereValueExample(SchoolContext dataContext)
        {
            // Sets data context.
            _context = dataContext;
        }

        public void Example1()
        {

            // Declares SqlQueryBuilder.
            var sqlbuilder = new SqlQueryBuilder();

            // Defines a SQL statement and adds an OR condition to the WHERE clause: Title = "Physics".
            sqlbuilder.Select("*")
                .From("Course")
                .Where("CourseID", SqlBuilder.Parameter<int>("courid"))
                .OrWhereValue("Title", "Physics");

            string sql = sqlbuilder.ToSqlString(_context);

            Console.WriteLine(sql);

            /*This code produces the following output:

            SELECT
            *
            FROM [Course]
            WHERE ([CourseID] = @courid
            OR [Title] = N'Physics')
           */
        }
    }
}
