Any help is much appreciated.

Thank you.

PS: I also tried creating system properties glide.script.use.v3.rhino (set to false) and glide.script.use.es6 (set to true) but in vain.

@Shaji_Kalidasan 

you are running this script from scoped app?

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi @Ankur Bawiskar,

Currently, I am running this script in the global scope.

Thank you

You are going down a rabbit hole with this approach IMHO. This approach is not supported.

1. There is no OOB field named 'column_name' on sys_dictionary, the field is 'element'.

2. There is no need to create records in sys_metadata, as that table is the parent of sys_db_object, sys_dictionary, sys_documentation.

3. An update set that captures a Table definition contains sys_db_object, sys_dictionary, and sys_documentation records.

While the script changes I proposed worked for me at first, they no longer do after deleting that table. I hope this helps.

Hi Bert,

Thanks for the heads-up and insights. It is always better to fail fast, reflect, and introspect rather than proceed with the current approach. I shall revisit this approach and explore alternative solutions. Your guidance has indeed saved both time and effort. I am marking your reply as helpful but not as a solution-I trust you shall comprehend the situation. My heartfelt thanks.

Thank you.

Sincerely,

Shaji Kalidasan
