stored procedures

Has anyone come across a job where they actively refuse to use stored procedures? I'm trying to understand what the rational is.
The third party product we are using right now has thousands of tables, not a single stored procedure.

I think they were trying to make their product portable (between different databases).

But correct me if I'm wrong most Databases out there (the big ones at least) all use SP's?

Can you take source code of stored procedures for one database, say SQL Server, and use on another, say Oracle?

At my previous job we were using MySQL ( X| ) and when we finally upgraded to a version that supports stored procedures there was an incentive from some developers to use them, but the boss didn't let it happen. He was afraid the DBA would play with the stored procedures and break something.

Wow, at my company it always the DBA is afraid of others breaking something.

up until v5, MySQL didn't have any stoProc support.

Yes, and I left shortly afterwards. The reasoning was that the database might one day be changed from say SQL Server to something like Oracle or Access, and stored procedures might no longer work on the new system. In actuality, even very simple queries can vary greatly between different DBMS's, so you're still going to have to modify everything - only now it's all hard-coded into all your applications and is a total PITA. For example, the following query in SQL Server will not work in PostGres:
select top 1 * from Customers order by CustomerIDYou have to turn it into something like this:select * from Customers order by CustomerID limit 1If you want to have a completely database agnostic application, you're going to need to use a middle layer to translate calls between your application and the database. We are using DevForce from IdeaBlade[^], and it works really well. Of course, we have no plans to change the underlying database but if we had to, then it would be a hell of a lot easier with DevForce managing everything! To summarize, IMHO there is no reason not to use stored procedures in a system that supports them, and there are many benefits to be gained when you do use them.The StartPage Randomizer - The Windows Cheerleader - Twitter

Well, it often works both ways - everybody is afraid of other people breaking something :)

In a previous life we used SQL Server CE, and it didn't support stored procedures. We also made the decision to reuse the embedded CE C# code on the desktop platform (write once, use in both places). So we ended up with a desktop system that couldn't use stored procedures either.

Maybe "General IT discussions" or "General Database discussions" would be a more appropriate forum. "They" the company? No. Well, wait, maybe... Rather than get into a dissertation on why I personally don't write stored procedures, I'll simply answer the question: There was one company that not only didn't have referential integrity on the production databases, but wouldn't even allow me to write functions in the database because, "the metadata would bog down the database". I assume that if the database supported stored procedures, they wouldn't use them either (this was in 2001, using RDB on OpenVMS). I knew that having the functions I wanted would greatly improve the performance of what I was writing, so I had my program create the functions it needed and drop them when it was done. :-D

Oh, good, thanks. I lost that link when I got laid off. There was another one too.

I think its about control more than anything. The last place I was at did this and it was dreadful to read through the code. They eventually moved some code to the DB so it wouldn't time out. Here it is a bit weird. I think it's a control issue again.

As far as I know only the most basic syntax will be portable such as select ... from ... where ... Proprietary T-SQL syntax from Microsoft is not compatible with PL\SQL.
You are right but not only the syntax, also the code organization is completely different. In Oracle using a top-level functions and procedures /outside the packages/ is considered like very bad practice.

My current employer refuses to use stored procedures - despite me literally begging. Their reason - the existing developers (2 of) haven't used them before, and don't understand / know how to write them. They also seem to think that it wouldn't be possible to write stored procedures to cover certain cases - where they are building SQL on the fly - but in 99% of cases this is because the are as thick as 2π_E_/v

Isn't SPs are faster than queries in code? And also you can save some round trips from code to db.
Be careful, there is no Undo Button(Ctrl+Z) in life.

Not a SQL guy, but at my last two companies there wasn't an absolute ban, just a "keep them to a minimum and make sure they're really justified" rule. The issue being that stored procedures have big impacts on scalability. Why have the server do something the client could be doing?

No - not necessarily.

Sometimes. My summary of the pros and cons is this: Comparing SP with simply hand-coding the SQL in the application, there's little doubt that SPs are preferable - they can be tested independently, tweaked for efficiency etc. without an application change. There can be run-time efficiencies in using SPs but these are (generally) not significant. Using some sort of automatic SQL generation layer in the application seems to be the 'solution' to not using stored procedures. I guess this is fine (I imagine the layer using reflection to look at an object, converting each property into a field on the insert - possibly using attributes to determine the column names and any special functionality pertinent to that field. However - developing this layer is, I think, complex and time consuming. If you re-use the layer then I guess it can save development time - but I like to split projects between developers, so my DBA can develop stored procs - the interface is agreed between the software developer and the DBA - then I don't care how he does it - as long as the Stored Proc sores and retrieves the information I need, efficiently. My fear of 'automatic' sql generation is in the exceptions that come along - leading to a more complex layer, harder to debug if something goes wrong. With a SP, i can easily identify bottlenecks, and have them easily looked at independently of the application. I can then oftentimes modify the SPs on the production system without the need to redeploy my application.
