Examples

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

using SnapObjects.Data;
using System;

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

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

        public void Example7()
        {

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

            // Defines a WHERE clause whose value is specified by the ISqlWhereCondition object.
            var where = SqlBuilder
                .Where("DepartmentID", SqlBuilder.Parameter<int>("id"));

            // Defines a SQL statement and adds an AND condition to WHERE clause.
            // The condition is specified by WHERE clause defined above.
            sqlbuilder.Select("Title")
                .From("Course", "a")
                .Where("CourseID", SqlBinaryOperator.GreaterThan,
                      SqlBuilder.Parameter<int>("courid"))
               .AndWhere(where);

            string sql = sqlbuilder.ToSqlString(_context);

            Console.WriteLine(sql);

            /*This code produces the following output:

            SELECT
            [Title]
            FROM [Course] AS [a]
            WHERE ([CourseID] > @courid
            AND ([DepartmentID] = @id))
           */

        }
    }
}
