Developing A Database System
Jul 16, 2013
company is developing a database system containing information about cities, towns, and villages in the country. The number of cities, towns, and villages are in thousands and the database program should allow users to search a particular place by name. Users should also be able to search all places that match a particular value or range of values for attributes such as location or population size. This particular feature is known as a range query.
If the database is meant to support range queries that can return many cities that match the query specification, the entire operation may be allowed to take longer. To meet this requirement, it will be necessary to support operations that process range queries efficiently by processing all cities in the range as a batch, rather than as a series of operations on individual cities.Different indexing methods can be used to perform this operation. What will be your choice if:
a) database is created once and has no change over a period of time
b) database is created once and database is changed over a period of time

I need to create a query that will pull all of the records that are statused as 'OUT' from my RECORDS table and then get the last (chronologically) 'OUT' record from my IN/OUT table for each record it pulled from RECORDS.
I can get the records out of RECORDS without any problems but I don't know how to set up a query that will pull the last chronological 'OUT' record from my IN/OUT table. Is there a way to do this in SQL?
Thank you in advance for any help.

Good Day;I would appreciate assistance developing a query that I haven't beenable to develop without using a second table. I wish to count thenumber of records that are still open on the first of each month.Each record has an open date and a close date or the close date isnull i.e., the record is not yet closed. I've previously beaten thisby building a table, simply a list of the dates for the first of eachmonth for the next ten years or so, and then selecting values basedupon a date selected from that table. However I'd be happier if Icould do it without the second table. I'd be prepared to accept theMin(Date) for each month as being the first of the month.I've included some DDL statements to build and populate the table ifthat helps. Since the selection is rather small and all the opendates are very close together I think the result will be simply adecreasing count from the month the first record is opened till today.A pseudo code select statement might look likeSelect Min(DateOpened) As DateOfInterest, Count(*) as [Qty Still Open]FROM DetailTWhere DateReceived > DateOfInterest or DateReceived is Null andDateOpened < DateOfInterestGroup by Min(DateOpened)Order by Min(DateOpened)I hope I've explained it sufficiently well.CREATE TABLE [dbo].[DetailT] ([Autonum] [int] IDENTITY (1, 1) NOT NULL ,[QDNumber] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[DateOpened] [smalldatetime] NOT NULL ,[DateReceived] [smalldatetime] NULL ,)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C15788', '06/04/2005 9:35', 07/04/2005)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B16091', '06/04/2005 9:36', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B15001', '06/04/2005 9:51', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('M18696', '06/04/2005 9:56', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C14969', '06/04/2005 10:05', '10/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('O10091', '06/04/2005 10:08', '12/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('D01197', '06/04/2005 10:13')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('H15001', '06/04/2005 10:15', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('J15090', '06/04/2005 10:24', '08/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('J01202', '06/04/2005 10:31')Insert into DetailT (QDNumber, DateOpened)VALUES('G01193', '06/04/2005 10:32')Insert into DetailT (QDNumber, DateOpened)VALUES('K01164', '06/04/2005 10:35')Insert into DetailT (QDNumber, DateOpened)VALUES('K01162', '06/04/2005 10:48')Insert into DetailT (QDNumber, DateOpened)VALUES('F01124', '06/04/2005 10:59')Insert into DetailT (QDNumber, DateOpened)VALUES('H01147', '06/04/2005 11:01')Insert into DetailT (QDNumber, DateOpened)VALUES('S15068', '06/04/2005 11:10')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('E12322', '06/04/2005 11:32', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('A12205', '06/04/2005 11:37', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('D12259', '06/04/2005 11:40', '07/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('C03394', '06/04/2005 11:51')If you made it this far thank you for your patience.

Hi,
i'm making my master thesis about a new plug-in algorithm, with the LVQ Algorithm.
I make the tutorial with the pair_wise_linear_regression algorithm and i have some doubts. i was searching for the code of the algorithm in the files of the tutorial and i didn't saw it. I have my new algorithm programmed in C++ ready to attach him, but i don't know where to put him, in which file i have to put him to start to define the COM interfaces? And in which file is the code of the pair_wise_linear_regression algorithm in the SRC paste of the tutorial?
Thanks

I am in the planning stages of a front-end to access sql server databases. The project involves analysis of stored data as well as storing results of the analysis. The classes for the analytical part is fairly complex so I would like to speed up the data manipulation part of the project. I am already familiar programming with ADO but I was hoping for a more complete solution. Is there a sdk or example code (third-party OK) that could facilitate this?
The client is not especially fond of .NET and would prefer to use VB6. However, with the right solution, C# or VB.NET would be acceptable languages.

I'm beginning development on a medium/ sized in-house web based system. Well moving from asp/mysql to asp.net/sql server. Re-doing DB design as well.My question is does it make sense for me to develop the SQL DB in Visual Studio 2005 pro, and then later move it to a real SQL server? Or basically what is the best and/or most practical way to do this development. Any other IDE's out there?Thanks

Hi all,
I am trying to write a program that creates packages on the fly depending on the variables you pass. for eg. It should create connection managers on the fly specific to a certain file in the variable (eg. sample.csv). the package has a dataflow task and it has flat file source and oledb destination.The problem I am facing is the flat file source when assigned to a flat file connection manager(dynamically), it is not giving any source output columns. i.e, the value for DFSource.OutputCollection(0).OutputColumnCollection.Count is Zero. But when I use the same code and reverse the source and destination(oledb as source and flatfile as destination), it is working fine. I searched everywhere for resources on how to develop packages programmatically, but could not find any except one example on msdn. If anyone knows about this prob or any useful resources on this subject, it would be really helpful.
Thanks,
Prithvi.

Hi...
I have the full version of SQL Server installed on my machine and am developing an app using BI DTS packages, VB.Net, SQL SPs, etc.. I will need to deploy this app w/SQL Server Express (SSE).
-Do I have to install SSE on my development machine for the purpose of creating the install package of my application? I am afraid that if I do install SSE on my machine, it may mess up my installation of the full version of SQL Server... will it?
-Can you point me to a link with information about how to do the development with the full version of SS, and create the installation package using the SSE?
Thanks for your help.

Hi,
I am new to SQL 2005 CE but fairly experienced with SQL 2000 and know my way around SQL 2005. I am creating a PDA app that must support the following scenario:
My company has a SQL 2000 server with a "computer assets" database. This asset database must be able to be transferred to an .sdf file (SQL 2005 mobile) on the PDA when the user docks their PDA to the desktop PC (not the same machine as the SQL 2000 server). This transfer can be via an option in the mobile app that is initiated by the user, or automatic.
The mobile application basically supports stock-taking of the assets, so users go out on site and record information about the assets. This information is stored in a separate .sdf database on the PDA.
When the user gets back to the office they dock with their desktop and then must transfer the data from the second .sdf database onto the SQL 200 server. Lets call this the "asset metadata".
thats basically it! but im having issues finding the right process to attack the data transfer tasks.
My issues:
- Firstly, how do i populate the .sdf on the PDA for development purposes? Microsoft tutorials seem to be geared at SQL server 2005 management
studio only. I only have SQL server 2005 Management Studio Express on
my development machine as well as all the necessary SQL 2005 CE SDKs and VS2005. We
do not use SQL Server 2005 at my organisation as yet and it will be some time before we migrate across. In effect im looking for something that behaves like a DTS package to transfer data across.
- How to populate the "asset database" .sdf file from the SQL 2000 server when the user has docked to their desktop PC? (This needs to be refreshed )
- How to transfer the "asset metadata" from the .sdf on the PDA to the SQL server?
ive looked at merge replication a little but am not sure whether this is what i need and again most online information seem to be tailored to SQL Server 2005.
Can anyone kindly point me in the right direction?

There seems to be a BUG in BIDS when developing SSIS packages using the Import/Export Data wizard.
If you use the wizard to import a large number of tables, and then select all the tables, and then choose to delete exisiting data in each table, the PrologueSQL file does NOT get built correctly. Instead of having a
TRUNCATE tablename Go
for each table, it just has a bunch of "Go"s with nothing between them. In the step immediately prior, where you confirm what the wizard will do, it tells you, after each table, that it will delete any existing data...but it doesn't do this.
If, during the wizard, I select each individual table one at a time and tell it to delete existing data, then it will get built correctly, but not if I select them all at once...YET, if I do select the whole block, choose delete existing data, and then select any single table, it shows that table as being set up to delete existing rows.
This is very frustrating when trying to import large numbers of tables.
Am I missing something? or is this really a bug?
Thanks, Jeff

Hi,
I've been scouring the forums and the web for anything that would substantiate an argument for database application developers to keep developing in SQL 8.0 when we have migrated to SQL 2005.
I read somewhere that compatibility 8.0 mode is an intern stepping stone for migrating from 8 to 9, but it seems 2005 will handle and run compat 8.0 databases just fine.
So am finding it really diffucult to substantiate my argument against running 2005 with all databases in compatibility 8 mode indefinitly.
Any suggestions or links that could help me with this.

Dear all,
We started to develop a datawarehouse solution for client back in December 2008 based on SQL 2008.
We are convinced that we can use some of the new feature included in the new version which is the reason we we chossed to go down this path.
Due to the delay of the next version we have some question that I would like to hear you opinion on.
The estimatet "go live" date is during spring (march/april)
Is it wrong to contiue the development on the 2008 version?
We would need to run Release candidate at the customer site until the product is released. Is there any major changes coming up that are already known?
So far in the development we have had no big problems with releasecandidate.
Thank you for you feedback.

I am writing a custom task to import data from delimited files into SQL tables. I use the standard Flat File Source adapter, a custom transformation to add a URN column and a filename column to the data and the standard OLEDB Destination Adapter.
Most of my test data files work fine except for ones with a lot of columns (around 350 columns). I get an error when I call the ReinitializeMetaData() method for the destination adapter.
Q1) Is there a restriction on the number of columns (or data row size) that can be imported into an OLEDB Destination Adapter?
Q2) The reason I use this adapter rather than the SQL Server Destination Adapter is that I need to set the destination table name using a variable. I don't believe I can do this with the SQL Server Destination Adapter. Is this the case?
Q3) Anyone know of a better/alternative way of acheiving the above? One way I have thought of is to create a custom destination adapter using the SQL Server Destination adapter as the base but I'm not sure whether this is a) possible and b) worth the hassle.
Hope someone can help...
Cheers
Nick

I have created a windows library control that accesses a local sql database
I tried the following strings for connecting
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"
I am not running the webpage in a virtual directory but in
C:Inetpubwwwrootusercontrol
and I have a simple index.html that tries to read from an sql db but throws
the error
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)

at System.Data.SqlClient.SqlConnection.PermissionDemand()
at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,
etc etc
The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Trusted
I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security
I think that a windows form connecting to a sql database running in a webpage should be simple
to configure what am I missing?

Hi,
I am developing a native C++ application using SQLCE (.NET is not a current option). Am having a problem while using multiple accessors for multiple blobs in a table. After I read the data for the first blob & try to read the data for the second one, I get an error in one of the dlls (something about using heap data that was freed). Where can I get symbol data so that I can use something like Windbg to resolve my problem.

We are developing Microsoft SQL Server CE 2.0 Merge Replication Using .NET Compact Framework. There is need of sinhronizations between SQL 2005 Mobile Edition witch resides on Barcode terminal (Windows CE) and SQL 2005 Developer Edition (on Windows XP). Everything is done by the book. There is few lines of code that we are using:
public bool Replicate()
{ bool ret = true;
SqlCeReplication repl = null;
try {
// Instantiate and configure
SqlCeReplication object repl = new SqlCeReplication();
string dbFile = ........
repl.InternetUrl = this.InternetUrl;
repl.InternetLogin = this.InternetLogin;
repl.InternetPassword = this.InternetPassword;
repl.Publisher = this.Publisher;
repl.PublisherDatabase = this.PublisherDatabase;
repl.PublisherLogin = this.PublisherLogin;
repl.PublisherPassword = this.PublisherPassword;
repl.Publication = this.Publication;
repl.Subscriber = this.Subscriber;
repl.SubscriberConnectionString ="Data Source=" +dbFile;
if (!System.IO.File.Exists(dbFile))
{ repl.AddSubscription(AddOption.CreateDatabase);
}
repl.Synchronize();
}
IIS is configured, but in log on the server we've got this error:

Hello all,
I've been asked to build a .net web application, where users will be able to upload, search and view images. There will probably be about 2000 - 10000 users who will upload and view photos each day.
Each image that is uploaded, is saved as a thumbnail, a small image, and the original. So considering the possible amount of data being uploaded, stored, searched for and viewed, whats the best way to store the images? Database or File system? Whats would be the fastest option for a web application? Should I even be looking at a different solution?
cheers!

From another post I have found out the some replication problems I am having are due to this discrepancy.
I have reapplied SP2 hoping it would change the resource db version, but it did not. Is there another way I can upgrade the resource db without re-installing SQL from scratch?
Thanks!
