Hows does SQL server works internally:
What are his steps in the execution of a query?
Where/how does he storage the information while executing a query?
What type of Index he uses?
and so on ...
If anyone knows a website that contains this type of information about the SQL Server SGBD and could share it i would be most appreciated!
Unbelieveible!
I can not seem to find any source for questions database related that don't include using 2.0 controls just as the come out of the box!
HELP!!!!
Simple issue (or so it seems) but I can't get an anwer:
Example:
TextBox.Text has information that I want placed in a table in a sql database. So I build a SQLDataSource control, and the triggers to fire the insert method. I modify the InsertCommand of the SQLDataSource so that it will write my record to the table. Something like...
InsertCommand="INSERT INTO MyTable(Description, Status) VALUES ('TextBox.Text', 'Default New Record Status)"
Now... the problem is with 'TextBox.Text' . When formated as is. the text string TextBox.Text is inserted into a record in the target table. My problem, the simple one remember, is refering to the text string stored inside of TextBox.Text and have that value stored in the new row under the Description column.
I can't believe that no one can help with this simple problem. Once resolved then my page is done... this is ALL that holds it up and I can't find a reference to how to go about it.
Thanks,Ken....

Hi,
I'm working on both VWDEE and VBEE and, in each, when I try to add a database diagram I get the following error message 'Invalid Class String' (after the 'Do you want to create required objects' prompt).
Can someone postulate a reason? If I don't get an answer i'll be pretty much dead in the water
Thanks in advance of your help.
"Falling back on cursors because they remind you of datasets will result in poor performance "
Hi, The above quote was from an article which advice to use store procedure and avoid T-sql in the body of a webpage.
Anyway, To me, I always use cursor when I want to process one row at a time. Is there an alternative to cursor in MS sql server to have similar results.?
thanks
Al
Please suggest correct answer (A,B,C,D) for the following Question
You are developing an application for a worldwide furniture wholesaler. You need to create an inventory table on each of the databases located in New York, Chicago, Paris, London, San Francisco, and Tokyo. In order to accommodate a distributed environment, you must ensure that each row entered into the inventory table is unique across all location. How can you create the inventory table?
A.Use the identity function. At first location use IDENTITY(1,4), at second location use IDENTITY(2,4), and so on.
B.Use the identity function. At first location use IDENTITY(1,1), at second location use IDENTITY(100000,1), and so on.
C.CREATE TABLE inventory ( Id Uniqueidentifier NOT NULL DEFAULT NEWID(), ItemName Varchar(100) NOT NULL, ItemDescription Varchar(255) NULL, Quantity Int NOT NULL, EntryDate Datetime NOT NULL).
D.Use TIMESTAMP data type.
Give the suitable answer for the below question and explain the answer.
1.You have designed the database for a Web site (or online ticketing agency) that is used to purchase concert tickets. During a ticket purchase, a buyer view a list of available tickets, decides whether to buy the tickets, and then attempts to purchase the tickets. This list of available tickets is retrieved in a cursor.
For popular concerts, thousands of buyers might attempt to purchase tickets at the same time. Because of the potentially high number of buyers at any one time, you must allow the highest possible level of concurrent access to the data. How should you design the cursor?
(A). Create a cursor within an explicit transaction, and set the transaction isolation level to REPEATABLE READ.
(B). Create a cursor that uses optimistic concurrency and positioned updates. In the cursor, place the positioned UPDATE statements within an explicit transaction.
(C). Create a cursor that uses optimistic concurrency. In the cursor, use UPDATE statements that specify the key value of the row to be updated in the WHERE clause, and place the UPDATE statements within an implicit transaction.
(D). Create a cursor that uses positioned updates. Include the SCROLL_LOCKS argument in the cursor definition to enforce pessimistic concurrency. In the cursor, place the positioned UPDATE statements within an implicit transaction.
do not have time to go through BOL .. but whats the command beside dbcc freeproccache to clear the cache .

Hi,
I'm trying to write a "GetQuote" procedure with a single @Quantity parameter. The purpose of the query is to sum the total cost (price * quantity) of a given (quantity) given the available "Sale" items. The sale table has the following structure:
[SellOrderID] [uniqueidentifier] DEFAULT (newid()),
[OrderDate] [datetime] DEFAULT (getdate()),
[UserID] [nvarchar](50) ,
[SellPrice] [float] ,
[SellQuantity] [int] ,
[QuantRemaining] [nchar](10) NULL,
**QuantRemaining is the sell quantity remaining after existing partial trades on the Sell Order - intentionally denormalised.
A given quantity may be satisfied by multiple 'Sell Orders' and these should be processed from the lowest price first.
e.g. give the following:
SellOrderID QuantRemaining Price
A 100 $2.00
B 300 $3.00
C 200 $1.75
D 350 $2.50
GetQuote 400 should return:
Sum((200*$1.75)+(100*$2.00)+(100*$2.50))
I am relatively new to the DB game and am having problems creating a SQL statement to do this. If anyone has a solution for this it would be greatly appreciated.
Thanks

For some reason I can't reply from within your message.
Make sure you have the same version of SQLserver and service pack on the SQL Server and the workstation you are trying to set up the package from, this is error due to different versions.
Your comand should look like: dtsrun /~S.... /~U ..... /~P ....

Hello
I have created a very simple DTS package to transfer data from one database to another on the same server. I am able to successfully execute the package from DTS. But if i try to schedule the package and run it from SQL agent it fails. The job that is created by the SQL agent appears as follows -
'DTSRun /~Z0x2939C85E61C391613034D42DC85BA5E18B1E12D06DC31F 242542405E07594E436B58219AC124F29B80EDEB464ACB52BA 977BF7A0E59BE9C183507AF7CDA9EB1033C1E04009EC5D4467 E1955FB83FA31BC185F4D4398F51F008BDE6677D23F9C5571A 4C3010B0ED1943C234'
and the error message i get is invalid switch .... DTS command invalid options
I have tried working with the /N and /!Y options and they dont work either. Can someone please tell me why is this problem occurring in the first place.

Hi all,
Nobody helped me on other SQL forums, I hope here people are better. Here is my problem : I'm trying to uninstall replication before to re-install it (2 servers working on Windows NT and SQL 6.5 SP5). On the publisher server, I chose Server/Replication Configuration/Uninstall Publishing, but then, I'm not able to re-install publication, as the 'Install Publishing' option is disabled. I've found somewhere on the web that I had to remove the distribution option from the system, which disables replication, with the sp_ServerOption stored procedure :
sp_ServerOption "myserver", "dist", false
then I've deleted the distribution database, but all this didn't change anything, the 'Install Publishing' option is still disabled. How can I get the option enabled ?
Thanks in advance if you can help me. Sorry for the English, it's not my native language.
I have a view based on few tables okay
I have a query that gives me document details of various revisions
Now i also get the latest rev of those if i use a MAX() in my Query
Now a case where i have say
Docu Numb - Revi - Received Date
Document1 - rev0 - 10/2004
Document1 - rev1 - 11/2004
Document1 - rev2 - 12/2004
Document1 - rev3 - 01/2005
Document1 - rev4 - 02/2005
Document1 - rev5 - 03/2005
Document1 - rev6 - 04/2005
Document1 - rev7 - 05/2005
If i query for latest it gives Document1 - rev7
And if i filter for a month of 12/2004
If i query for latest it should give Document1 - rev2
Now i need to get a filter with latest as rev2,
plus i also need as a indication of actual latest as rev 7
using a query
How do i do that ...
Coz when i use filter for a month and Max then it
does not consider rev7 for that filter and skip the record
and if i try to filter only as per month .. i get a wrong info
as latest rev2 which is not a true info as per database records.
May i possibly get both ... filtered info as per specific month and
also a rev info as what is the latest for a spec document.
Just i need to know is that possible .. in SQl using a query
Any more info needed please mail me on

Guys
Hunting high and low for the definitive answer to this query.
I need a system to enable the import of a csv file (trypically contacts exported from Outlook) into a SQL Server table unique to that user through a .aspx page.
At the first and most basic level I need to simply get the data into a table.
The ultimate goal though is to have a fully functioning system whereby the user can sync between the csv file and the database enabling them to upload the data for the first time then only update changes subsequently (new records/changes to existing records) etc.
1. Does anyone have code that does such a thing?
2. Does anyone know of a component/utility that can be purchased off the shelf.
3. Is there someone with the capacity to write such a module?
regards in anticipation
Andy.
Hi Folks,
Easy SQL question....first to answer correctly gets...the satisfaction of knowing he helped a fellow developer in need.
Runnning SQL 7.0 on an NT 4.0 platform in a client server network environment. Authentication is done on the NT level. Each user has his/her own name and password. Most users use the same shared software app.
QUESTION: Can the same user login to multiple machines concurrently and run applications without fear of locking or hanging or causing other mischief?
TIA.

I have installed sql express on clients machines. I don't want them to be able to view the sp's or the functions. I would like to go as far as not allowing them to see the tables. I tried with encrption but this is still breakable by the user using the DAC.

For several weeks I have been wrestling with this common problem! I could not connect to my SQL Server 2005 (express edition) server remotely.
I read all the documentation. I did days of research and found no solution! Many seem to have the problem, but none seem to have the answer! I followed every suggestion, including Microsoft's own instructions and NOTHING!
So, just on a whim, I tried something... and it worked.
In my connection string, I added the instance name... (DATA SOURCE=127.0.0.1SQLEXPRESS)
Crazy, but true.
I hope this helps anyone struggling with the same issue!
If you write a stored procedure to "SELECT MAX" from a table and the answer is null since the table is empty, how is the null answer returned to the program from the stored procedure? Do you actually get the letters "NULL" or do you just get a space? How should you define your variable in your program?
Thanks in advance!
I'm wondering if there is any way for me to execute any type of command (delete, insert, create, alter, etc) on management studio without having to wait the server answer.

Icurrently have it as the example below. But this doesn't allow foreach result set to be displayed separately.<td valign=top><b>Active Primary:</b><%= ActivePrim %></td>Any help would be greatly appreciated.Catherine
