Examples

The following code example demonstrates how to use the AndWhereValue method to add an AND condition to the WHERE clause. In this example, the AND condition specifies that the Title value must start with "C" (specified using a LIKE operator).

using SnapObjects.Data;
using System;

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

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

        public void Example2()
        {

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

            // Defines a SQL statement and adds an AND WHERE condition: Title like 'C%'.
            sqlbuilder.Select("*")
                .From("Course")
                .Where("CourseID", SqlBinaryOperator.GreaterThan,
                        SqlBuilder.Parameter<int>("courid"))
                .AndWhereValue("Title", SqlBinaryOperator.Like, "C%");

            string sql = sqlbuilder.ToSqlString(_context);

            Console.WriteLine(sql);

            /*This code produces the following output:

            SELECT
            *
            FROM [Course] 
            WHERE ([CourseID] > @courid
            AND [Title] LIKE N'C%')
           */
        }
    }
}
