Anyone know where I could find some good articles about pros and cons of upgrading SQL 7 to SQL 2K?
Our boss suddenly got this bug up his rear that we need to upgrade. :(
Probably because we are to a point where everything is running smoothly, and he needs to throw a monkey wrench in it.
We are a very small shop, and are not stressing SQL 7 in the least. I am interested to read some articles about SQL 2K, because right now, I can't see any possible reason an upgrade would be worth doing.
Thanks.
I have a requirement where I need to perform a query for positioninformation. But for some types of entries, I need to "expand" the rowto include additional position rows. Let me explain with an example:An index is a security that is made up of components where eachcomponent has a "weight" or a number of shares. So if I have 1 share ofthe index, I have X shares of each component.AAPL is an Equity, CSCO is an Equity, SPY is an Index. Lets say thatSPY has one component, AAPL, with shares being 10. (1 share of SPY = 10shares of AAPL).So, I do some trading and I end up with positions as follows:+10 AAPL-5 CSCO+2 SPYThe query I need returns:+10 AAPL-5 CSCO+2 SPY+20 AAPL (from 2 SPY * 10 shares)which becomes (after grouping):+30 AAPL-5 CSCO+2 SPY-----------------------------------------Based on that criteria and the following schema (and sample data):-- Drop tablesDROP TABLE [SecurityMaster]DROP TABLE [Position]DROP TABLE [IndexComponent]-- Create tablesCREATE TABLE [SecurityMaster] ([Symbol] VARCHAR(10), [SecurityType] VARCHAR(10))CREATE TABLE [Position] ([Account] VARCHAR(10), [Symbol] VARCHAR(10), [Position] INT)CREATE TABLE [IndexComponent] ([IndexSymbol] VARCHAR(10), [ComponentSymbol] VARCHAR(10), [Shares] INT)--Populate tablesINSERT INTO [SecurityMaster] VALUES ('AAPL', 'Equity')INSERT INTO [SecurityMaster] VALUES ('MSFT', 'Equity')INSERT INTO [SecurityMaster] VALUES ('MNTAM', 'Option')INSERT INTO [SecurityMaster] VALUES ('CSCO', 'Equity')INSERT INTO [SecurityMaster] VALUES ('SPY', 'Index')INSERT INTO [Position] VALUES ('001', 'AAPL', 10)INSERT INTO [Position] VALUES ('001', 'MSFT', -5)INSERT INTO [Position] VALUES ('001', 'CSCO', 10)INSERT INTO [Position] VALUES ('001', 'SPY', 15)INSERT INTO [Position] VALUES ('001', 'QQQQ', 21)INSERT INTO [Position] VALUES ('002', 'MNTAM', 10)INSERT INTO [Position] VALUES ('002', 'APPL', 20)INSERT INTO [Position] VALUES ('003', 'SPY', -2)INSERT INTO [IndexComponent] VALUES ('SPY', 'AAPL', 25)INSERT INTO [IndexComponent] VALUES ('SPY', 'CSCO', 50)INSERT INTO [IndexComponent] VALUES ('QQQQ', 'AAPL', 33)-- *****************************-- Based on the rules:-- 1) Index positions appear like other positions (account /symbol) pair, but-- its components show up as new rows of account (of index),symbol (equal--to component symbol), position (equal to shares * index position)-- 2) One row for each account / symbol pair (GROUP BY account andsymbol, SUM position)-- Expected output (without grouping) (sorted by account / symbol)-- 001 AAPL 10-- 001 AAPL 375 (component shares * index position) (25* 15) (SPY)-- 001 AAPL 693 (component shares * index position) (33* 21) (QQQQ)-- 001 CSCO 10-- 001 CSCO 750 (component shares * index position) (50* 15) (SPY)-- 001 MSFT -5-- 001 QQQQ 21-- 001 SPY 15-- 002 AAPL 20-- 002 MNTAM 10-- 003 AAPL -50 (component shares * index position) (25* -2) (SPY)-- 003 CSCO -100 (component shares * index position) (50* -2) (SPY)-- 003 SPY -2-- Expected output (with grouping account / symbol) (sorted by account/ symbol)-- 001 AAPL 1078-- 001 CSCO 760-- 001 MSFT -5-- 001 QQQQ 21-- 001 SPY 15-- 002 AAPL 20-- 002 MNTAM 10-- 003 AAPL -50-- 003 CSCO -100-- 003 SPY -2---------------------------------------------Is a UNION the best way to perform the query.

It seems to me that either by accident or design, SQL Server tends to steer you away from backing up directly over the network.
Are there reasons for not doing this because you obviously don't want to leave your backups on a local drive in case the drive fails?
Some possibilties that I can think of are:-
1. Local drives have faster access times and SQL backups can get quite large. I did a quick test and found that a netwrok backup takes 2 to 3 times longer than it does on a local drive.
2. Backing up on the netwrok could hog too much bandwidth. I haven't tested this and would be surprised it it's true.
3. There could be some reason that you don't want the Server and Agent services running under a domain account but want to leave them on the Local System account. I am not aware of any such reasons by the way.
4. Local drives persumably have a slightly higher availability than network drives. If the server is running, the drive should be available.
Like in the subject: What are the cons and pros of using nvarchar(max) versus ntext?
Does it have something to do with having to enable full text search perhaps in the latter case?
I'm just wondering what any pros and cons of using multivalue columns in a database are.
I'm designing a database which will have a column for FABRIC_TYPES_AVAILABLE for a certain FURNITURE_ITEM. Each FURNITURE_ITEM can have multiple FABRIC_TYPES_AVAILABLE of course. So I was just going to store a 2 or 3 digit number of the FABRIC_TYPES_AVAILABLE in that row. So I would have something like....34,24,453,32,23,45,67,65,43,21,21,45.
Anyway....thanks in advance for any information. Links I could read would be great too...b/c I did do a bit of searching, but didnt find much.
I have a main database...for this large Web site...and Im wondering
what would be the PROS and CONS of using another database (located on
the same, or on another SQL Server). Im just thinking this would be
good incase we ever needed to take some load off one of the servers.
Also, we will be integrating Community Server into this Web site. Of
course you know CS adds its own database objects which crowd up our
main database objects.
We were thinking of giving CS its own database also; bad practice, or....it doesn't matter much?
Thank you

Are there any vices to using default constraints on all columns in your table.
For example an Int that defaults to 0
or a char or varchar that defaults to ''
I know that 0 and Null are not the same thing. But if your programs don't have the concept of NULL then you have to convert the NULL to zero.
So, DEFAULT CONSTRAINTS on every column. Is it good or Bad?
Thanks

Can someone provide information or a link to information regarding the pros and cons of saving files directly into a SQL 2005 database?
I'm actually for saving files to a database (cleaner implementation then just saving the location then having to get the file, etc), but my project manager is not convinced so I need to make an argument for (or against depending on what I actually find out) using varbinary data type.
Thanks.

We're contemplating the migration/storage of a large number of packages, a minority of which designed in dts (SQLServer 2000) and using third party activx components.
thanks much for any feedback,

We are in the process of replacing our primary production server. In the process of determining how SQL server is going to be structured, it has been suggested that I place all current and new indexes on a separate file group. These filegroups would then reside on a separate shelf on the server. What are the pros and cons of doing this?

Hello. I have recently installed MS SQL SERVER 2005 and when I was installing it, it asked me for the username and password, and there I had 2 options: either write my own, either select "Use Windows Authentification". I selected the "Windows Authenthification" ( I guess that means that it uses my username and password from Windows ).
Now, Im trying to connect to the Server using Java and JDBC, but I have a problem: I have to specify the username and the password of the connection! My windows' only account is "Vlad" and I have no password. I tried these options, but it didn't work. I also tried with empty string "", and with "sa", "sa" but it didn't work either. I get an error saying that "Login failed for user 'Vlad'. The user is not associated with a trusted SQL Server Connection."
Any ideea of what the username/passwords are or how to get them?.
Thank you for your time.

Question: I have searched here and on Microsofts site already but it seems that all solutions require already either some ASP2 knowledge or MSSQL knowledge .. I am quite new in both but need to realise this for a project.
I have installed a MSSQL 2005 server running MSSQL2005 Standard in mixed authentication mode. Services running using a domain account created for this purpose.
I have then created a simple database called test with a table called testtable
All I need to achieve now is a simple ASP2 page, which is located on the DC IIS, which connects to the SQL server (in same domain but different server) using WINDOWS authentication and returns the result of
SELECT * FROM TESTTABLE
I try now for a couple of days so I hope someone could help me with this .. I really need a step by step guide what I need to do on the SQL server side (so a specific user can connect to this particular database) and on the IIS side ..
I know it is always painful to help someone with little knowledge but I am getting desperate.
Thanks a lot guys
Hi,
Anybody now how to this programmaticly ? in registry or TSQL statement ?
All,
I work with Microsoft SQL Server 2005 on windows XP professional.
I'd like to create stored procdure to add image to my database (jpg file).
I managed to do it using VARCHAR variable in stored procedure
and then using EXEC, but it don't work directly.
My Table definiton:
CREATE TABLE [dbo].[Users](
[UserID] [int] IDENTITY(1,1) NOT NULL,
[Login] [char](10),
[Password] [char](20),
[Avatar] [image] NULL,
CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED
(
[UserID] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
My working solution using stored procedure:
ALTER PROCEDURE [dbo].[AddUser]
@Login AS VARCHAR(255),
@Password AS VARCHAR(255),
@AvatarFileLocation AS VARCHAR(255),
@UserId AS INT OUTPUT
AS
BEGIN
SET @Query = 'INSERT INTO USERS ' + CHAR(13)
+ 'SELECT '''+ @Login + ''' AS Login, ' + CHAR(13)
+ '''' + @Password + ''' AS Password,' + CHAR(13)
+ '(SELECT * FROM OPENROWSET(BULK ''' + @AvatarFileLocation + ''', SINGLE_BLOB) AS OBRAZEK)'
EXECUTE (@Query)
SET @UserID = @@IDENTITY
END
I'd like to use statement in the stored procdure:
ALTER PROCEDURE [dbo].[AddUser]
@Login AS VARCHAR(255),
@Password AS VARCHAR(255),
@AvatarFileLocation AS VARCHAR(255),
@UserId AS INT OUTPUT
AS
BEGIN
DECLARE
@Query AS VARCHAR(MAX)
SET @AvatarFileLocation = 'C:hitman1.jpg'
INSERT INTO USERS
SELECT @Login AS Login,
@Password AS Password,
(SELECT * FROM OPENROWSET(BULK @AvatarFileLocation, SINGLE_BLOB) AS OBRAZEK)
SET @UserID = @@IDENTITY
END
It generates error:
Incorrect syntax near '@AvatarFileLocation'.
My question is:
Why it does not work and how to write the stored procedure code to run this code without errors.
Thanks for any reply
