Oracle 19C New Feature Availability

15/02/2019 Leave a comment

trump-exasperatedSince Oracle Open World 2018, Oracle have been trumpetting a few cool new features in the Oracle 19C database, the headline two for administrators being “Automatic Indexing” and “Real-Time Statistics“.

With the release of Oracle 19.2 on Exadata (on-premises – not yet on Cloud!) this week, we also got the documentation released which allow us to answer a very important question: on which platforms will we be able to use these 2 (and other) new awesome features. We may not like the answers – Oracle has decreed that we cannot have them on-premises for SE2, Enterprise Edition or on an ODA.

This is confined purely to Exadata on-prem and the cloud offerings. That’s it. There are no technical reasons why this should be the case – it’s just code – so the restrictions can only be marketing-based (like Hybrid Columnar Compression).

I’m disappointed, but it does mean that the over 80% of Oracle database clients still not living in the cloud should continue to need that aspect of my services!

SQL Developer insight

05/09/2013 Leave a comment

When using SQL Developer, there is a feature called Completion Insight which help you write SQL and PL/SQL in the SQL Worksheets. It will auto-pop helpful things, like object name when typing a SELECT statement, column names if it is aware of the object which you are accessing and things like that.

The pop-up seems to pop-up inconsistently, appearing when I don’t want it and not appearing when I do. I finally snapped and decided to work out (look up) exactly how this feature works. And it’s like this.

1. Make sure your SQL is correctly formed. If you have multiple bits of SQL in the Worksheet, and they are not terminated with a “;” or “/“, then it can get confused about where you are contextually within a statement and not pop-up.

2. The Auto-popup has a delay of either 0.3s (SQL) or 0.6s (PL/SQL). This can be changed in Tools -> Preferences -> Code Editor -> Completion Insight. I have now set a 1.0s delay so it’s not quite so eager to appear.

3. You want the pop-up to appear? Press CTRL + SPACE. If it still does not appear, then it cannot determine your SQL Context (see point 1) or there’s nothing to pop.

Hope this helps you. It’s certainly helped me.
