Exploring the Attachment Linking Process in ServiceNow

[Santosh Oraon]

I hope this message finds you well. I wanted to extend my sincere appreciation for the wealth of knowledge shared here.

Could someone please shed some light on the process by How attachments are linked to the 'sys_attachment' table in ServiceNow?


Thank you very much for your time and assistance.

Hi @Santosh Oraon! I'm not entirely sure what you mean by the "linking". The attachments are saved in base64 in 4k chunks, and written to [sys_attachment] table. Here's a great article on the topic written by a SN engineer:

Please mark this response as useful and the question as solved if the issue has been solved. Thank you!

Attachments aren't linked to the sys_attachment table. The records in the sys_attachment table are the attachments and they are linked to the records they belong to. See below article for a better understanding.
