Anyone have a recommendation on SSIS classes (providers and instructors)? It looks like Brian Knight's classes must be at the top of the list. His classes are always full!
As you all know, in Framework 2.0 on the desktop platform you have the convenient "abstract" Db* classes that can be used to write more generic code. For instance System.Data.SqlClient.SqlConnection inherits from System.Data.Common.DbConnection, and so forth. Now the docs clearly say that this applies to the corresponding classes in the Compact Framework. And i have seen this implied by other web searchs I've done. However this does not seem to be the case -- or, I'm missing something somewhere.
The following simple code on the desktop platform compiles OK:
using System.Data;
using System.Data.Common;
using System.Data.SqlClient;
DbConnection conn = new SqlConnection();
However it doesn't compile in a compact framework project: "Cannot implicitly convert type 'System.Data.SqlClient.SqlConnection' to 'System.Data.Common.DbConnection'".
Reflector also indicates that the Compact Framework class doesn't inherit from DbConnection.
OK, so am I missing something here, or what was the reason that Microsoft did it differently??
I'm still trying to transition from a DB-centric view to an OO view,
and I could use some help from any of you OO-design wizards out there. A very common db representation is Table A, Table B, and Table A_B, which maps the two in a one-to-many relation. E.g., create table Companies ( companyId int, name varchar ); create table Products ( productId int, name varchar ); create table Companies_Products ( companyId int, productId int ); So how does this translate into object-land? I started with: public class Product public id as integer public name as string end class public clas Company public id as integer public name as string public products as generic.list(of Product) end class OK,
so far, so good -- I've represented most of my data. But I've lost some
important information: given a Product object, I have no easy way to
find out which company sells it. SQL: scan the Companies_Products table OO: iterate through companies, nested iteration through company.products. Do I just add a function to my data access layer that does the lookup? Is that allowed? On
a side note: can anyone recommend a good intro to OO design
specifically for database programmers? It seems like most of my
confusion comes from issues of translating tables into classes. Thanks!
I am using SQLXML to pass data back and forth, well I am trying to. Itry to follow a tutorial but it didn't work completely. Here is myproblem.

I saved the result in Test.xml.3. Ran XSD on it. C:Test>XSD TEST.XMLThis MS utility wrote out the schema file, TEST.XSD4. Ran XSD on it to create the class. C:Test>XSD TEST.XSD /classes/language:csThis MS utility wrote out the CS class file, TEST.cs5. Added the CS file to my project, create a class around it and thecode is below.My problem is that when I put a break point where is says BR (in thecode below), pNotifications has no data in it.

I am trying to use VB.NET to run SSIS packages. However I don't have the various dts namespaces available. When I attempt to import them I only have Microsoft.SqlServer.Server in intellisense.
I am running on XP sp2, VS 2005 (full install) and even went so far as to install sql 2005 sp1 full install on my local machine.
What gives with only having Microsoft.SqlServer.Server available?

Hi all,
Do I still need to write the .sql query statements (in SSMS) if I use the ADO.NET connected classes like GetSchema method or the DbDataAdaptor Object?

Thanks!
I show business objects in the ReportViewer as it is described in the MSDN article [1]. In the article they only use intrinsic types like int and string as properties of the business object.
My business objects contains also structs and classes (e.g. Point) as Properties. I expected the Reporting Services to call the ToString() method if it is not an intrinsic type. But it only shows the error string "#Error" in the TextBox.
How can I show a Struct property of my business object as a report value?

I work on the Clinical Surgery Department Data Application.
The patient gets through the Admission, Surgery, PostSurgery and Discharge stages during his staying in the department. The Doctors just insert their medical data in to the different tables. I have three main classes: User, Patient and Portfolio ( patients portfolio ) and all the business bases on these classes.
The problem is with the Classes per Medical Data Tables. The Medical tables should exist cause it includes the medical data about the patient however what is not clear: Whether I should create Business and Entity classes per each medical data table ( and this is something like 50 tables ) or I should insert all the functions in the Portfolio class and then there will be a mess of functions in one class? What is the accepted way to perform it ?

Please help.
I need to know how to refresh Linq-To-SQL classes after schema changes without dropping and adding them.
Now, when I make a schema change (such as add or delete a column to a table), I want to "refresh" the Context.dbml file.
The only way that seems to work is to drop the table from the Context.dbml designer and then add it back in.
Is there a better way to do this?
How are others doing this?
Please advise.
Thank you.

Hi,
Hopefully someone out there will be able to help me with this question. I'm trying to setup my C# program to use the Backup and Restore classes to perform backups and restores on an SQL Express 2005 database.
From the documentation I've read... it seems that when you go to restore the database, it's a good idea to backup the current transaction log. But when I do this using the Backup.SqlBackup method I get an error saying that no database backup is detected so a log backup can't occur. I'm not sure if this has something to do with the fact that I moved my backup files from the default SQL Express/Server Backup folder to a different location. Shouldn't it know I've already performed a backup though?
And does anyone know how to set a parameter to backup to a different file location than the default? I've been doing a backup then a file move. Works the same, but it would be nice to have everything together in the Backup object.
Thanks!
What would be the best SELECT technique to use in order to retrieve all the O'Brians from a last name field. The data is imported into our table from an outside source and the name O'Brian, etc isn't always consistant. It could look like
O'Brian
O Brian
O Brian
OBrian
You get the idea.
The same could apply for McDonald, Mc Donald, etc...
Thanks.

We're having issues with Microsoft's 64 bit Oracle OLE-DB driver... when we escalated to Microsoft PSS they recommended that we go with Oracle's OLE-DB driver since Microsoft's hasn't been modified in a few years.
I've seen a lot of differing opinions on this topic (almost everyone says do not use Oracle's driver) and am wondering if there's a definitive answer here.

Hi
I've got a SQL database running on Windows NT 4 Server (P400, 256 Ram, 8Gb IDE & 18Gb SCSI HDD) and quite a few of the queries are taking a long time to run, and are also using a lot of the processor time. This affects other users who are also trying to query the db. Has anyone got any recommendations for upgrading the hardware spec to improve the overall performance? I presume just add more RAM, and get a dual processor system?
Thanks

I am a PHP programmer for a small startup. We are storing person records and our MS SQL Server 2000 database has grown to the point where we wish to paginate the data before returning it to my PHP scripts.
I was wondering if anyone has any recommendations on an optimal way to manage this given the following requirements.
- Data must return only X number of rows at a time (user configurable).
- Must be able to search by several diffent criteria (name, date, birthday, location, ...)
Also, I was wondering if it is possible to return the total number of existant rows of data as the first row of a MSSQL procedure.
I have a SQL 2005 database containing the location of graphics files. I want to start learning how to write a C# application that will get a path from the DB and display the file. Any recommendations on sites where I can start learning how to do this?

Ok, let me start by saying that I already checked the FAQ. There was one link, but it just seemed to go to a review page with 5 books, with pretty specific themes. So I'm surprised that such a basic topic as book recommendations for SQL newbies wasn't covered.
In my case, I'm not a total newbie. I learned to write SQL queries for work on both Oracle and SQL Server, and I've gotten pretty good at all the basics. So I've got "SQL for Dummies" down cold, so to speak. Now I'm looking to take my query writing ability to the next level, which I guess would be the intermediate level. I'm also looking for books that are specific to just SQL Server, rather than the books about general querying on any DBMS. Speaking of which, just so you all know, "SAMS Teach Yourself SQL in 21 Days" is an Oracle book, no matter what it says on the cover.
It looks like the book "Inside Microsoft SQL Server 2005: T-SQL Querying" comes highly recommended, but I flipped through it on the shelf at a bookstore the other day, and I think it's over my head. It might be a good reference to have around, but I think I'd be totally lost trying to read it from cover to cover.
So does anyone have recommendations for books that go beyond "This is how to do a SELECT, and here's how to do a JOIN", but won't make my head explode?
Thanks in advance,

I do software support for software that works with both Oracle and SQLServer, so I mostly just write queries to look at the data related tothe software. When I first started, I bought a couple of books to learnthe basics, intentionally going with generic books that would help withboth types of databases. I've got the basics down, and now I'm lookingfor a really detailed reference book that goes really indepth intoquerying for SQL Server specifically. Currently, we only work with the2000 version, but we'll be going to 2005 soon, so I think I'd rather gowith a book on 2005, although if you know one that covers thedifferences between them, that would be great. Any recommendations?Besides just writing queries, I'd also like to learn more about SQLServer in general. DBA software support, so I'd like to head mycareer in that direction. I was looking at Microsoft's newcertification path for SQL 2005. Given that my company won't pay tosend me for training, and I really don't want to have to put down$2200+ to pay for a class, I was thinking that I might be able to learnenough on my own to pass the first test and get the MCTS title. Iordered the Training Kit from Microsoft Press for that, which comeswith a 180 day trial of SQL Server 2005 to play with, along with a hugebook. Does anyone have any other recommendations for resources to helplearn this stuff?--Richard

View 1 Replies View RelatedHi all,
I've recently been tasked with doing some SQL 7.0 administration and was wondering if anyone could recommend a good book to get started. The bulk of my IT experience is in SMS, IIS and messaging so my database fundamentals are pretty weak.
As I see it, it's probably a three-step process to get me at least halfway comfortable - a first book to get some solid general database / SQL-language exposure, a second book that takes the knowledge to a more advanced level and finally a MS-specific book that covers the Microsoft implementation of a SQL server.
Any comments / suggestions would be much appreciated!
Cheers,

I've searched quite a bit, and have found several leads on schema, stored procedure, and database contents comparison scripts and tools.
I'm now looking for recommendations on which ones are best, easiest:
ObjCompare.exe
sb_ABCompareDb.sql
sp_db_comp.sql
There's a mythical script from Andrew Z <mumble> that Mike Hotek talks about...
There's a DBCompare on the Back Office Resource Kit 2 CD, which of course is not in the umpteen MSDN CDs :-(
There's some *other* command line dbcompare, or maybe db_compare.
There's a DBA Compare.
I need to be able to compare divergent schemas from two developers to integrate their changes, so need schema and stored procedures compared only, and would also like to have something to compare staging servers and production servers.
Leads on other choices also welcome. I'd be happy to summarize and post, if warranted.
Hi,
I've been using Sybase for some years but by employer is moving (you guessed it) to MSSQL.
Can anyone recommend a TSQL and performance tuning training course for MSSQL in the London area?
Thanks,
Rob.
I'm a solid SQL developer/dba and have some funds earmarked for training this year. I'd like to expand my dba skills...more specifically, I'd like to become a rock-solid enterprise level dba that has not only a solid foundation of skills but some innovative techniques for managing our corporate SQL servers.
I'm curious if anybody has recommendations on training or conferences that might help me dig into those skillsets for a couple of days.
Thanks for your insight.

View 1 Replies View RelatedWe have an application that was built and testing using SQL Server Express. One of our clients is deploying it using SQL Server Standard and plans to put the data files and log files on separate disk volumes.
In allocating the available disks to the volumes, they are looking for a recommendation on how big the log file volume versus the data file volume should be. Over time there will several years worth of data in the data files. I assume the log files need to be at least big enough to log all the changes between back-ups. Are there any general rules of thumb? Or whitepapers that discuss the trade-offs?

Howdy folks,
I'm trying to get a better idea of how I should set some of the SSCE connection properties. I will be deploying the application on a WinCE5 board with a 4G flash storage card and 512MB RAM. The application must run 24/7 with a medium amount of traffic. At any given point I expect up to 3 connections to the same database. I'd really like to keep performance high without risking any database corruption issues. As such, I need to make sure my connection properties are optimized.
I read from Joao's article that setting DBPROP_SSCE_MAXBUFFERSIZE = 1024 gave a considerable performance increase, while anything higher gave diminishing returns. Is this for a certain amount of RAM, or is it uncorrelated to RAM size?
What's the best practice for specifying DBPROP_SSCE_TEMPFILE_DIRECTORY and DBPROP_SSCE_TEMPFILE_MAX_SIZE? Is it possible in WinCE5 to directly put it in RAM? How big do these temp files get?
I've read of some bad experiences with autoshrink. Are there any reasons not to set DBPROP_SSCE_AUTO_SHRINK_THRESHOLD to 100 if the database will be compacted regularly?
Any other advice for the more obscure settings such as DBPROP_SSCE_FLUSH_INTERVAL or all the lock settings?
Thanks a bunch!
I am in the process of creating a user interface that will give the users a list of reports to choose from. I wanted to write an interface in ASP .NET with C# to pull information for different reports from the reporting services web service. I have successfully done this with C# Windows Form. The project requires it to be web-based.
Problem is, I am new to web forms and would like a recommendation for reference materials to help me program ASP .NET with C# and using the web service. I am still learning ASP .NET and C#, so I would like something fairly basic.
Any help is appreciated.
This really isn't a SQL Server specific question, but more tword SQL in general. I am pretty good at SQL, being able to perform joins on several tables at one time.

It would be challenging to me to learn how to do more complex queries involving three or more tables.
