No columns were bound prior to calling SQLFetch

I am currently working on a project with the following techstack:

• Database: Intersystems IRIS
• Controller: PHP/PDO with IdiORM

The problem is that the IDs are not in a common format. For example: “ABX||242149||1||0||D” – So there are different keys seperated with “||” as delimiter. As long as the ID’s are like “232||ABH” the request with IdiORM is working but an ID like the first example gives the error message: “No columns were bound prior to calling SQLFetch”.

PHP code:

    class TestController
    {
       public function test()
       {
          $out=IRIS::for_table('')->raw_query("select id from Bestand where artikelnr='430030'")->find_array();
          echo json_encode($out);
       }
    }

Are there any restrictions for IdiORM due to the ID format? It seems like the ORM cant map the given ID to the ID column?
