У меня слишком большая длина необработанной переменной проблема при выборе значения поля BLOB (сохраненная строка JSON) из таблицы.
Запрос:
select utl_raw.cast_to_varchar2(dbms_lob.substr(TRANSACTION_DATA)) from PS_ISA_INB_PAYLOAD_LOG;
Это мой SP, который я использовал для вставки объекта JSON в поле BLOB:
create or replace PROCEDURE SDIX_TICK_LOG
(
ORGANIZATIONNAME IN VARCHAR2
, TRANSACTION_TYPE IN VARCHAR2
, TRANSACTION_DATA IN BLOB
, TRANSACTION_STATUS IN VARCHAR2
) AS
l_r RAW(32767);
l_blob blob;
