Examples

The following code example demonstrates how to use the ThenByRaw(string orderClause, string alias) method. It retrieves records from the "Course" table, sorts the records by DepartmentID in ascending order, and then sorts the records by Title in ascending order (using a raw SQL).

using SnapObjects.Data;
using System;

namespace Appeon.ApiDoc.ISqlOrderThenBuilderExamples
{
    public class ThenByRawExample
    {
        private SchoolContext _context;

        public ThenByRawExample(SchoolContext dataContext)
        {
            // Sets Data Context.
            _context = dataContext;
        }

        public void Example2()
        {
            // Declares SqlQueryBuilder.
            var sqlbuilder = new SqlQueryBuilder();

            // Defines a SQL statement and retrieves all the records from the "Course" table.
            // Sorts the records by DepartmentID in ascending order, and then sorts by Title in descending order.
            // Specifies "ThenByDesc" as the alias for the ThenBy raw SQL.
            sqlbuilder.Select("*")
                .From("Course", "C")
                .OrderByAscending("DepartmentID")
                .ThenByRaw("Title desc", "ThenByDesc");

            // Converts to raw SQL for the database corresponding to the data context.
            string sql = sqlbuilder.ToSqlString(_context);

            Console.WriteLine(sql);
            
            /*This code produces the following output:
            
            SELECT
            *
            FROM [Course] AS [C]
            ORDER BY
            [DepartmentID] ASC,
            [Title] DESC
            */
        }
    }
}
