BLTOOLKIT: Ele suporta iQueryable?

Question

Geralmente com o Bltoolkit, busco dados do banco de dados da seguinte maneira:

using ( DbManager db = new MyDbManager() )
{
    IList<MyObjects> objects = db
        .SetCommand(query)//sometimes with additional parameters
        .ExecuteList<MyObjects>()
        ;
}

Eu gostaria de ter capacidade de fazer o seguinte:

using ( DbManager db = new MyDbManager() )
{
    IQueryable<MyObjects> qObjs = db
        .SetCommand(query)//sometimes with additional parameters
        .ExecuteQuery<MyObjects>()// here I don't want query actually to be executed
        ;

    // ... another logic, that could pass qObj into other part of program

    IList<MyObjects> objects = qObjs
        .Where(obj=>obj.SomeValue>=SomeLimit)    // here I want to put additional filters
        .ExecuteList()  // and only after that I wan't to execute query and fetch results
        ;
}

É possível alternar a solução que, com a modificação da linha de consulta orignal (modifique onde parte), mas às vezes é bastante complicado.

Existe alguma maneira fácil de fazer isso?

Obrigado. Qualquer pensamento é bem -vindo!

Answer 1

using ( DbManager db = new MyDbManager() )
{
    IQueryable<MyObjects> qObjs = 
        from p in db.GetTable<MyObjects>()
        //sometimes with additional parameters
        select p;

    // ... another logic, that could pass qObj into other part of program

    IList<MyObjects> objects = qObjs
        .Where(obj=>obj.SomeValue>=SomeLimit)    // here I want to put additional filters
        .ToList()  // and only after that I wan't to execute query and fetch results
        ;
}

Se você quiser ter um iQueriable, você deve usar o LINQ. BLTOOLKIT.LINQ e BLTOOLKIT.DATA.LINQQ DEVEM IMPORTAR.

        IQueryable<DataModel.Object> query  = db.Object;


        If ((int)cmb_somthing.SelectedValue) > 0 {

            int ID  = (int)cmb_somthing.SelectedValue;
            query = query.Where(m=> m.ID = ID);

        }
        query = query.Where(m=> m.Date >= StartDate &&
                                m.Date <= EndDate);
