Examples

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

using SnapObjects.Data;
using System;

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

        public OrWhereExample(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 OR 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"))
               .OrWhere(where);

            string sql = sqlbuilder.ToSqlString(_context);

            Console.WriteLine(sql);

            /*This code produces the following output:

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