Example defining annotations on a table and column in Oracle Database 19.28

Example defining annotations on a table and column in Oracle Database 19.28

With all the new stuff in the 23ai RUs, it can be easy to overlook some cool changes in 19c such as

Schema annotations have been backported to 19.28

These enable you to add key-value metadata to describe tables, columns, and other database objects

Oracle23ai - a SQL-Macro for Epoch - The Better version. TL;DR: I had a function to produce "Epoch", similar to python. When I tried to speed up function-calls by using a macro I found an interesti...

The "epoch" function got better by turning it into an SQL-Macro.

Non-positional insert statements (23.9)

INSERT INTO … SET col1 = val1, col2 = val2, … for row-based inserts
INSERT INTO … BY NAME SELECT … to match query column aliases to column names

Non-positional insert statements (23.9) INSERT INTO … SET col1 = val1, col2 = val2, … for row-based inserts INSERT INTO … BY NAME SELECT … to match query column aliases to column names

Non-positional inserts

Assign column values in the SET clause for row-based inserts:

INSERT INTO … SET col1 = val1, col2 = val2, ...

Match columns from the source table to the target table in INSERT-SELECT by name rather than position with

INSERT INTO … BY NAME SELECT …

Outer Joining With ANSI SQL-89 and SQL-92 Introduction I recently implemented a quick fix for the rule G-3130 to transform queries to ANSI SQL-92 syntax. One of the challenges was to handle Oracle’s outer-join syntax (+). In ANSI SQL-89, join...

Do your outer join queries produce more rows than expected? In this blog post, I show a strange result when using filter predicates in the join clause.

dbLinter can help you sort your join and filter criteria and spot issues like this.

I always bluntly refuse for exactly these reasons, plus I pay extra for extra legroom which I don't intend to give up because *they* can't do basic math: [cubic meters of overhead compartment space] / [number of seats] = [max size of carry-on]

I'm pretty confident there will be further development.
It's just that being able to use these things in with clauses is such a basic feauture (note: not saying easy to implement) that if I was running the show (thank god I'm not) it would never have been releases without it.

I know. Very annoying too.
Very nice feature, but it's time we get a new and improved one IMHO.

Do you know that feeling when you're with the one you deeply love, but suddenly, out of the blue, they do this annoying thing again, and in that moment there's nothing you want more than get a divorce?

Looking at you Oracle 🤬

I just noticed the 23.8 version of 23ai Free has a different file name to previous versions. It now includes the version number. Nice!

This can be particularly useful for estimating pipelined table functions
