Managing enterprise content in OpenText Documentum involves more than just storing documents. It requires the ability to retrieve, analyze, and manipulate metadata-rich content efficiently. This is where Documentum Query Language (DQL) becomes essential. DQL is a powerful SQL-like language designed specifically for querying and managing Documentum repositories.
Whether you’re new to Documentum or refining your administration skills, here are three critical things you need to know about using DQL for effective data management.
At a glance, DQL may look like SQL, but it goes deeper. It’s designed to work with Documentum’s object model, where everything – documents, folders, workflows – is an object with rich metadata.
Key capabilities DQL offers that SQL doesn’t:
Example:
SELECT object_name FROM dm_document
WHERE ANY keywords = ‘urgent’ and FOLDER (‘/MyCabinet‘, DESCEND)
Tip: Use ANY when working with multi-valued properties to avoid incomplete query results.
DQL includes a powerful set of functions that allow you to manipulate data on the fly – essential for reporting, audits, and clean-up tasks. Some essentials include:
Example:
sql
CopyEdit
SELECT COUNT(*) FROM dm_document
WHERE DATEDIFF(day, r_creation_date, DATE(NOW)) <= 7
This retrieves documents created in the past week – great for monitoring recent activity.
Writing DQL manually can be error-prone – especially with complex joins, nested queries, or when testing access control behavior. That’s where our all-in-one admin tool dqMan comes in.
You don’t need to memorize the DQL syntax – dqMan gives you real-time feedback, structured output, and built-in access to repository metadata.
