Parameters

clause System.String

A string of raw SQL to be added to the ON clause.

parameters SnapObjects.Data.ISqlParameter

Examples

The following code example joins one table with another based on multiple conditions. It uses the AndOnRaw method to add more conditions (in raw SQL).

using SnapObjects.Data;
using System;

namespace Appeon.ApiDoc.ISqlJoinOnAndOrExamples
{
    public class AndOnRawExample
    {
        private readonly SchoolContext _context;

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

        public void Example()
        {
            var sqlQueryBuilder = new SqlQueryBuilder();

            // Gets the DepartmentID values and Name values from the "Department" table, and Title values from the "Course" table.
            // Sets the condition to join the "Department" and "Course" tables: 
            // Department.DepartmentID = Course.DepartmentID, and Course.CourseID greater than the input argument.               
            sqlQueryBuilder
                .Select("Department.DepartmentID")
                .Select("Department.Name")
                .Select("Course.Title")
                .From("Department")
                .Join("Course")
                .OnRaw("Department.DepartmentID = Course.DepartmentID")
                .AndOnRaw("Course.CourseID > @courseid", 
                        SqlBuilder.Parameter<int>("courseid"));

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

            Console.WriteLine(sql);

            // Executes the SQL statement, and specifies the value for the input argument.
            var departments = _context.SqlExecutor.Select<DynamicModel>(sql, 2000);

            /*This code example produces the following output:           
              SELECT
                [Department].[DepartmentID],
                [Department].[Name],
                [Course].[Title]
              FROM [Department] JOIN [Course]
              ON [Department].[DepartmentID] = [Course].[DepartmentID]
              AND [Course].[CourseID] > @courseid
            */
        }
    }
