A few days ago, I came across the following problem: I currently work on a project where I am the responsible of an application which generates entries to a log table every time a job is executed. This table contains a lot of information on statuses of jobs, possible problems, exceptions, duration, aso. I was working on some analytics on this data and needed to enrich the data by the version of the software which generated the log entry (since we were not capturing this in the log table). From our configuration management tool, I was able to extract the dates when which versions of the software was deployed in production
My intention was to create a temporary table to join onto the logged entries, but I didn´t want to create the tables on the Oracle server (mainly because they would have been just temporary tables and because the schema-user I was using didn´t have the rights to create tables).
