GlideRecord - addJoinQuery(String table, String primaryField)

Adds a filter to return records based on a relationship in a related table.

For example, find all the users that are in the database group (users via sys_user_grmember table). Another example would be find all problems that have an assigned incident (problems via the incident.problem_id relationship).

This is not a true database join; rather, addJoinQuery() adds a subquery. So, while the result set is limited based on the join, the only fields that you have access to are those on the base table (those which are in the table with which the GlideRecord was initialized).

Always test queries on a sub-production instance prior to deploying them on a production instance. An incorrectly constructed encoded query, such as including an invalid field name, produces an invalid query. When the invalid query is run, the invalid part of the query condition is dropped, and the results are based on the valid part of the query, which may return all records from the table. Using an insert(), update(), deleteRecord(), or deleteMultiple() method on bad query results can result in data loss.

You can set the glide.invalid_query.returns_no_rows system property to true to have queries with invalid encoded queries return no records.
