Sorry: I'd misremembered. My is his daughter.
I'd always lazily assumed that it was part of the M$-led trend to call everything "my something-or-other": My Documents, My Videos, My SQL - it made sense. It was quite delicious to discover the truth.

Have you considered SQLite? SQLite Home Page
It might fit your use case. Some caveats, though
* It's a single writer/multiple reader. When writing, it locks the entire DB, (only for the duration of the write, I think), so if you need multiple, concurrent DB writes, then probably not for you
* Although you can declare fields as int, float, varchar, etc, under the hood SQLite stores everything as text, so you can do this:
sqlite> create table t(datum int);
sqlite> insert into t values('Hello World');
sqlite> select * from t;
Hello World If your DB will only be accessed by an application, it may not be an issue.
Update: On the plus side, it's about as fast as read/write on a plain file.

It might be a little primitive for my needs.
While no current projects require any real concurrency on writes I might certainly need it in the future, but particularly, I'd like a bit more data integrity than what you demonstrated above.
Thanks though. Isn't that an in memory capable DB or am I thinking of another one? There was one I was considering using in my projects as a kind of queryable dataset system.

SQLite can certainly be used as an in-memory database, but only within the context of a single process. So maybe not useful in your use case

Well, not for this scenario, but the dataset thing was intended for single process, in memory stuff. Think Datasets in .NET but for C++, for example, and queryable.

We dropped SQL Server in favor of PostgreSQL years ago, and never looked back. It has been multi-platform for a long time and is very stable. The only thing I regret is that they decided to use Python for the PgAdmin tool, the older version was written in C++ and much "leaner and meaner".

SQL for Linux is a good, reliable product. From experience...
If you are looking for something more multi-platform, go fro MySQL - a very good product too. Also from experience...

When you look for things, look for ANSI SQL.
Those are the common bits across the things SQL.
There are a few implementation/platform specific things. Like Oracle does 'sequences' and MSSQL has 'identity'.
But a big swath of most standard DDL/DML is highly portable.
And I'd say what I think really matters in RDBMS is more about set theory than it is about SQL dialects/specifics. Normalized vs denormalized and stuff like how to identify where indexes are going to help or where they may be more costly (in disk space and maintenance) than the ROI (in performance).

I believe SQL92 is ANSI?
Also my big concern isn't language, but actual maintenance of the DB.

One of the good things about PostgreSQL is that it does not need as much maintenance as SQL Server. Our customers usually don't have the skills to maintain an SQL Server properly. Of course this is dependent on how complex the database is.

Yeah I think so.
"These editions colloquially became known as SQL-86, SQL-89, and SQL-92. So, if you hear those names in reference to an SQL format, note that it is referring the various editions of this standard."

I wrote a SQL92 parser once so I'm pretty familiar with it except I often mix T-SQL in with SQL92 because the lines always blur for me.

One is inside the other, SQL92 has T-SQL in it.
|
|

I'd say T-SQL has SQL92 in it since T-SQL is essentially a superset, but I know what you mean.

Fair point, it cuts both ways.
Would you call one or the other a superset in relation?

T-SQL is roughly a superset of SQL92

Yeah that makes sense. I think in my head I lump T-SQL and PL/SQL together as DDL/DML.

Been doing DB for 40 years and that never came up.
First of course the goal is the enterprise solution and not the nuts and bolts. Architecture and design matter far more.
Most SQL is rather easy an mundane. And ANSI SQL works for that.
But more complex problems cannot be done at all in ANSI SQL. So attempting to limit oneself to that means ignoring features of the database that have been optimized over years or even decades to provide features like that. Versus silly things like attempt to figure out how to do it in a programming language rather than using the database itself.
Not to mention of course the real costs associated with licensing, maintenance and even the real cost of using existing knowledge of a technology versus attempting a new one.
So even if you can find a database that is not compliant, especially for most of the major parts, the consideration is just not worth the time.

For my part, as long as the database supports SQL92 as a baseline I'm willing to learn some of the DB specific features I need to be effective with it. I just intend to lean heavily on common SQL that works across DBs where I can.

You would probably need to look really hard to find a SQL one that doesn't do that.

Yeah, but I just wanted to be clear, and also eliminate the possibility of any half arsed implementations.
