using System;

namespace Appeon.ApiDoc.SqlBuilderExamples
{
    public class WhereValueExample
    {
        private SchoolContext _context;

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

        public void Example1()
        {
            var sqlquerybuilder = new SqlQueryBuilder();

            // Defines a WHERE condition.
            var where = SqlBuilder.WhereValue("name", "English");

            // Creates a SQL statement.
            var query = sqlquerybuilder
                .Select("*")
                .From("Department")
                .Where(where);

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

            Console.WriteLine(sql);
            
            /*This code example produces the following output:   
             
            SELECT

            FROM [Department]
