Good day gurus,
I have a script that populates tables on a regular basis that crashed and gave the above error. The strange thing is that it has been running for close to 3 months on the production system with no problems and suddenly crashed last week. There has not been any changes on the tables as far as I know.
Has anyone encountered something like this before? I believe it has something to do with the aggregate functions I'm implementing in it; but it worked initially.
please; kindly find attached the part of the script I've developed into a procedure that I reckon gives the error.
CREATE OR REPLACE PROCEDURE V1

v_a VARCHAR2(4000);
v_b VARCHAR2(4000);
v_c VARCHAR2(4000);
v_d VARCHAR2(4000);

v_f VARCHAR2(4000);
v_g VARCHAR2(4000);

The aggregate functions, commaencap_concat (encapsulates with a comma), or_concat (concats with an or) and semic_concat(concats with a semi-colon).
the remaining tables used are all linked to the main table DEMO.
I have checked the column sizes and there seems to be no problem. I tried executing the SELECT statements alone and they give the same error without populating the tables.
Any clues?
Many thanks for your anticipated support.
