I want to retrieve our stored knowledgebase articles regardless of the language they are in. However querying KnowledgeArticleVersion using SOQL requires a language be specified in the where clause or it produces an error. I don't want to have to separately query every possible language that might exist, is there a way to find out what translations for an article exist?
As per salesforce documentation on KnowledgeArticleId
It seems that you can filter on more than one language if you set an ID filter, simply add all the ID's then filter on the languages :)
