SQL != SQL...

Same here. I built a 'don't use this for anything else than this one purpose' update method and it finally seems to work - except that now something else is not updated correctly. Turned out to be the same thing our heroes pulled off on another table. And of course more extra hours for finding this. Now it's very late, I still have a one and a half hour trip home, will not get much to eat tonight unless I pick up some greasy junk along the way and would I love to strangle that idiot that invented the technique of updating primary keys and enforcing this nonsense with countless triggers.

If software development were a circus, we would all be the clowns.If there's anything worse than nested triggers, it has to be people fiddling with primary keys. You have my sympathies, and I wish your company would pay you for a decent restaurant. My old job actually had that as a rule, if you were forced to work past eight o'clock the dinner was paid for. Within reason.

Are you joking? They will cry how long it took me to find and correct it. They actually tried to tell us that we do and always have produced excellent quality - as a company guideline. If they say so, then it must be true and it must somehow be our fault when something does not go according to plan.

So I've been doing Oracle development, coming from SQL Server. Simple string concatenation, which is + everywhere, is || in Oracle. A little research and || seems to be the ANSI standard, which makes sense as 2 || 'A' is now unambiguous '2A' (and not a conversion error). But now I want to write a simple SELECT statement which would work in both Oracle and SQL Server. Oracle doesn't support + and SQL Server doesn't support ||, however both support CONCAT. Seems too easy for something that's uneasy already, and indeed it is... SELECT CONCAT('A', 'B') FROM TABLE works in Oracle and SQL Server. SELECT CONCAT('A', 'B', 'C') FROM TABLE works only in SQL Server... Seems like the only thing that works in both databases is CONCAT('A', CONCAT('B', 'C')). And that seems like the only reasonable solution is to write two different queries, one for Oracle and one for SQL Server because it's just too friggin difficult to implement a standard FRIGGIN STRING CONCATENATION!!!

When you stop doing presentation logics in the database. I also agree with Phil, why do you need to support more than one database?

If the minor differences between databases already make you cry, then please stay away from anything that has to do with browsers.

But it's the minor differences that cause the subtle bugs which take the most time and require the greatest pulling of hair to resolve.

So what you are saying is T-SQL <> PL/SQL? :)
Mongo: Mongo only pawn... in game of life.
For some of us, "Transact-SQL" <> [Transact-SQL]. In Sybase SQL Anywhere, you can get a current date-time value using "CURRENT_TIMESTAMP", "GETDATE( )" , "CURRENT TIMESTAMP" or "NOW( )". Good luck using either "CURRENT TIMESTAMP" or "NOW( )" in Microsoft SQL Server.

Ok, then it should be the probabilty of a subtle bug, weighted by its severity. :-O

Why is that important? If you're running some kind of application to interface with the database, seems like the call to the database should just invoke a sproc (for example--maybe a query, whatever). You have the same named sproc on two instances, but they work differently. The code layer is effectively calling an interface (i.e., "whatever I'm connected to, execute the 'selectMyStuff' sproc"), and each database is the concrete implementation of that interface. This is a simple example, but what if the databases had completely different structures? You wouldn't expect to deploy the same SQL to both, you'd have to write custom procedures which happened to take the same parameters and return the same result set (i.e., implement the 'interface'), even though they perform that operation in significantly different ways.

Yeah, normally I'd do that, but this time I'm generating the query client side :) Anyway, it's not all that important, I should abstract away such stuff and implement it for each database anyway. I was just amazed that something so simple can't be done uniformly by two of the biggest databases that both work with the same language that has an ANSI standard...

Sounds like a good time for some dynamic sql. I know lots/most folks dis the idea of such, but it certainly has its place imho.
Especially when you know how it works[^] :)
