Oracle Apex Query выдаёт ошибку «ORA-06502: PL / SQL: цифра c или ошибка значения: слишком маленький буфер строки символов»

Question

Я использую этот запрос в oracle запросах Apex с разметкой RTF. У sql разработчика этот запрос работает нормально и возвращает записи, как показано на снимке экрана, но когда я помещаю этот запрос в Oracle запрос Apex и связываю затем с кнопкой загрузки Oracle Apex выдает ошибку **

ORA-06502: PL / SQL: цифра c или ошибка значения: буфер символьной строки тоже маленький oracle апекс
