    ISqlJoinOnAndOr<TBuilder>.AndOn(ISqlJoinCondition condition) Method

    .NET Standard 2.x

    Adds the AND logical operator and a search condition (specified by an ISqlJoinCondition object) to the ON clause.

    Namespace: SnapObjects.Data

    Assembly: SnapObjects.Data.dll

    Syntax

      TBuilder AndOn(ISqlJoinCondition condition);
    

    Parameters

    condition SnapObjects.Data.ISqlJoinCondition

    An ISqlJoinCondition object which represents a search condition in the ON clause.

    This object can be created by using the SqlBuilder.On method and so on.

    Returns

    TBuilder

    Returns the TBuilder object which can be used to add more search conditions to the current ON clause.

    Examples

    The following code example demonstrates how to join one table with another on multiple conditions. It uses the AndOn method to add more conditions.

    using SnapObjects.Data;
    using System;
    
    namespace Appeon.ApiDoc.ISqlJoinOnAndOrExamples
    {
        public class AndOnExample
        {
            private readonly SchoolContext _context;
    
            public AndOnExample(SchoolContext dataContext)
            {
                // Sets data context.
                _context = dataContext;
            }
    
            public void Example7()
            {
                var sqlQueryBuilder = new SqlQueryBuilder();
    
                // Defines a JOIN condition.
                var joinOnCondition =
                    SqlBuilder.EmbeddedOnRaw("Department.DepartmentID = 1");
    
                // Gets DepartmentID values and Name values from the "Department" table, and Title values from the "Course" table.
                // Sets the condition to join the "Department" table and the "Course" table: 
                // Department.DepartmentID = Course.DepartmentID, and the JOIN condition defined above (Department.DepartmentID = 1).              
                sqlQueryBuilder
                    .Select("Department.DepartmentID")
                    .Select("Department.Name")
                    .Select("Course.Title")
                    .From("Department")
                    .Join("Course")
                    .OnRaw("Department.DepartmentID = Course.DepartmentID")
                    .AndOn(joinOnCondition);
    
                // Converts to raw SQL for the database corresponding to the data context.
                string sql = sqlQueryBuilder.ToSqlString(_context);
    
                Console.WriteLine(sql);
                
                /*This code example produces the following output:           
                  SELECT

                    [Department].[Name],
                    [Course].[Title]
                  FROM [Department] JOIN [Course]
                  ON [Department].[DepartmentID] = [Course].[DepartmentID]
