�IntegerConstantExpression

What it is

IntegerConstantExpression is used to create a Constant of the type Integer. A Constant is assigned when it is defined and can not be assigned during a session. The way it is used in the AI-Framework is by assigning a value in the code (so-called hard-coded), which will be translated into a IntegerConstantExpression by the AI-Framework.

• See LINQ for details about LINQ and the AI-Framework.
• Go to the category for all LINQ expressions.

Code example

private IEntityCollection<ArticleEntity> ArticlesToBeDeleted
{
    get 
    { 
        return Property(() => 
            Article.Select<ArticleEntity>
            (AutoLoad.Off).Where(a => 
            a.ArticlePrice.Matches(1, false, true))); 
    }
}

Explanation of the example

This is the definition of an Entity, based on ArticleEntity, with the name ArticlesToBeDeleted.
In it is a selection, where the ArticlePrice must match a Integer Constant, in this example 1.

So ArticlesToBeDeleted is a subset of ArticleEntity. The subset contains the� records where ArticlePrice equals 1.
