Any insult was unintentional, I was merely trying to emphasise the difference between the college type of question we frequently get here on CP and the real world.
For a 'quick and dirty' we all do things we wouldn't put into production.

As a long tme contractor, developing solutions in SQL, C#, VB.NET and ASP.NET, I have worked fr many clients (mostly blue chip financials), and the vast majority will not allow embedded sql, all database access is via stored procedures - for the very reason of change. Making a change to a stored procedure (which may then be replicated out) is far preferable and much quicker than co-ordinating an application roll out an to users worldwide for what may only be a one column change. As far as I am concerned embedding sql in a production strength application is an absolute no-no, but everyone to their own opinion.

What, even if your application is just kicking of one-time migration scripts in a specific sequence?

Here we have the difference. You see, I would not consider that a production app, although I do see what you mean - it running in a production environment. I consider a production app as one released out to users, running regularly, with all the overheads of releases. The situation described by you I would describe more as a utility program - one written to assist with a one off specific task. In this instance I would use (within reason obviously) whatever technique achieved the desired results in the shortest time.
Different perspectives make for misunderstandings I guess.

Fair enough. I see anything that runs on a live system as a production app - even if it is a one time thing like a migration process.

That's an arrogant attitude you've got going for you there Bob. Before you try belittling somebody, perhaps you ought to take a look at who they are. Let's see - Colin; Microsoft MVP. CodeProject MVP 2005 through to 2008. Author of several well respected articles. Which bit of this suggests that he doesn't write code for a living to you? Well?
Perhaps you should have dialled back the attitude a bit and actually looked at what Colin had to say - rather than taking the chance to blow your own trumpet.

OK, apologies to any one who was offended or felt they were offended. I have to admit, I didn't look at Colin's profile, but as I explained in a subsequent post, I was trying to emphasise the difference between the college type environment and the real world, where you are dealing with large volumes of data and performing much more complicated operations.
However, once again I apologise if anyone was offended.

Everything you can do in the body of a stored proc you can do in a regular sql call, and the engine does a pretty good job at caching execution plans. Most stored proc performance benefits have been optimized away over the past few releases of SQL server.

Nope I agree with Bob, while you "can" use embedded SQL it is not a good solution for a production app (and I have the same opinion of the 1 off solution). Mind you I'm in the same boat, long term contractor with financial institutions so probably run under the same restrictions.

The last app I worked on was a shrink wrap CRM application that allowed customers to add their own business objects and tables. For that we had to generate SQL dynamically. There are pros and cons to any approach. When I'm designing a basic application, I usually start off with stored procedures just because I like their simplicity.

Who said they were passing full tables? If you perform a query on a table you only get back what you asked for. You never get back the full table unless that is explicitly what was requested.

Well he/she said:
What is the benifit i get using stored procedure instead of tables in my web application using asp.net with c#
From what I understand of the question, he/she is pulling in the tables and splitting out the information he/she wants in C#/asp.net. Of course, I could be wrong in my interpretation as the question is not quite solid.

Convenience, if you use stored procedures, you are embedding a catalog of the sql queries used on the database with the database. It can make it more convenient to add indexes for those queries at a later point without having to search through the text in your profiler output.

Not shure I should ask this here but don't really know a better forum for it so here goes
Since about 4 hours now I'm (suddenly) unable to connect to my company's sql-server
The errormessage: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified
I tried everything I could find on the net (using google) but nothing works
I checked the server and the client protocols. All are enabled and match.
Using named pipes or tcp/ip doesn't change anything (same error)
My connectionstring:
"Data Source=<servername\instancename>;Initial Catalog=<dbname>;User ID=<id>;Password=<pass>"
The connectionstrings I tryed:
"Data Source=tcp:<servername\instancename>,1433;Initial Catalog=<dbname>;User ID=<id>;Password=<pass>"
"Data Source=np:<servername\instancename>;Initial Catalog=<dbname>;User ID=<id>;Password=<pass>"
I'm still able to ping to the server and even open network shares (read/write to the networkshare)
I tryed making an dns connection but that fails aswell
The only thing that changed is that the client was inserted into the domain yesterday but I was still able to connect this morning and at the moment I'm still logging in localy.
Otherwise nothing changed on the server or the client (no updates, no new software, ...)
There is no firewall enable on the server or the client.
The really strange thing is that when I started my programme at 12.25 everything worked perfectly but when I started it 2 min later I started to get this error.
In those 2 min nothing happend (I didn't even change any code)
The client logs show nothing for that moment.
I'm at a lost to what it might be.
Any help would be appriciated
EDIT:
the problem appears to have solved itself
I just tryed to connect again and now I have no problems anymore
If anyone has any suggestions to what it might have been please tell me because I hate it when things like this happen

I already replied to this, suggesting you contact the product vendor. Nobody else replied, either because they couldn't suggest anything better or they had no idea. Posting the same question again (with only 1 other question inbetween) will not help.

Have you tried the Firebird ISQL web site? they probably have more FAQs - it is their product after all

If I had three tables (the 3T) called Building, Floor, and Room (the data is what you'd probably expect) and I wanted to be able to manage inactive periods (or permanent shut-downs) of any one record in any of those tables, what would be the best way to do it?
My first thought (which doesn't seem elegant) was to create an inactiveId field in the 3T, referencing an Inactive table which would store the beginDate, endDate (if any), and inactivityReason. Now consider a floor is scheduled to undergo renovations from January 10th to February 10th and one of the rooms of that same floor is scheduled for a permanent installation of WiFi and AC outlets for every desk from January 2nd to January 29th.
Should I store the fields buildingId, floorId, and roomId in the Inactive table or is the inactiveId in the 3T enough? Should I create a trigger (or a scheduled function) to remove any "expired" inactiveId from the 3T (i.e. the affected room would have a null inactiveId on January 30th and the affected floor would follow suit on February 11th)?
If the above is completely wrongheaded, please let me know. I'm not a dba, just a lowly programmer. And, since I want to design it to be easy to use for future programmers, I don't need everything to be strictly normalized if there's a usability payoff for the end user (although my instincts are to usually go up to 3NF and 2NF).

A forth table with a table type, id field, inactive start, inactive end date, and reason code where the type and id are the primary key will give you a good starting point. It is better design to create three tables but if done right the one will serve you well.

If this is the main aspect for the design of the database, I would create the 3T primary keys the same way I would if it was an accounting system. A character key with the first 3 digits designating building, next 3 floor and the last three room (altered to your specs of course). This way you could include ranges of any size for your shutdowns without having to create multiple records for each structure.
It would come in very handy when developing a calandar of building projects. I usually try to avoid having any real meaning (besides row identifier) in my primary keys but, in this case it may make sense.
Building 5: 005000000
Second Floor, blg 5: 005002000
Room 234, 2nd Fr, blg 5: 005002234
Inactive Table
--------------
PrimaryKey
StartStructureId
EndStructureId
StartDate
EndDate

I would create the additional table on Room with an ID and from to date. If you deactivate a floor then create a record for each room on the floor. Please, do not prefix your ID field with any intelligence - it is a fundamentally bad design.
The reason for the room level table is to give you the most flexibility without inflicting a complex set of rules (around the level you want to disable). You could then create views that would count the number of disabled rooms and compare it to the floor, room count to identify a disabled floor/building.
