Saving Files (Binaries) Into Database - Pros And Cons
Jun 19, 2008
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.

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 am using transaction replication between a transaction and reporting database server. When I use a snapshot to initialize my subscribers, I currently get a lot of deadlocks during the snapshot creation. I am considering using a database backup instead. Can anyone tells me how to reduce the table locks that I am getting during snapshot creation or advice on using database backups?

My company is thinking about moving to a product that uses Microsoft SQL Server and I have been asked to find out what are the Pros and Cons of the product, if any.
Any feedback is appreciated.
Thank You

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. What are the pros andcons?

Hi alli am building a SQL 2000 database that it is proving a littlechallenging, i have companies with multiple addresses, phone numbers,owning mine sites etc and also joint ventures so maybe you get thepicture with a few design issues that i ma encounteringMy queriy is about a primary key identity, and which one to use withrespect to either the identity data type or the unique identifier ,I am aessentiall building an address table to hold all multipleaddresses as well as phone numbers etc, so my desire to have a uniqueidentity for each record is very important.My view is i will run in to violation errors by just using the tableidentity data type, i could i suppose use composit primary keys butthat may have a performance impact, although thiis will not be a hightransaction database.Does anyone know about performance issues regarding each identitysolution, by using a generated 16 bit identifier there are going to behuge numbers for the DB to verify. or am i worried about nothing?any views greatly appreciatedregardsGreg

Thanks for the help on the previous thread.
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 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

hi all,
I was wondering if anyone knows of any pros/cons on storing SSIS (2005) packages within SQL Server 2005 SP2.
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 there,
I was thinking about saving some files in a SQL Server DB and then reading those back to the client for download. Any warnings that I should know about before doing so? The files will generally be at most 2mb in probably .pdf format. I've heard bad things about doing this in Access...but then again, SQL Server isn't access.

Someone:
I have the need to upload a file via a webpage and then save that file into the database. I would also like to retrieve it and show it to the user.
Can someone show me an example of how this should be done. Also I am concerned of the pros and cons of saving files in the database. Is there a performance hit on the server? Will it make the database unstable? Has anyone had problems doing this?
Any suggestions, samples, and/or help are welcome.

I'm trying to do something which I hope can be accomplished relatively simply.
I have a report similar to bank statements let's say. When run, it currently prints out each person's statement into one file, with page breaks sepearating each person's statement. What I need to do, is when the report is run, save each person's report into a seperate file for the purpose of emailing to them later.
I could easily modify my report to just output for one particular person, but I'm not sure if there's a way to "bulk render" all the reports and have them saved to sepearate files.
I should also add that I'm using an MS Access Data Project (ADP) as the front end to my app - connected to a SQL Server 2005 DB. I currently display the reports by embedding a web browser object into an Access form and rendering the report via HTML.
Thanks in advance,

I am trying to automate a basic task using SQL Server 2005 Express.
Currently I have a query script that I run and then save the results as a CSV file. I need to do this on a daily basis and so I am looking to find out how best to go about this.

My install of SQL Server 2005 runs like a dog. The SQL Management Studio splash screen lasts for 10 minutes, then when the Studio window appears it takes another 5 minutes to initialize.
I have SQL server installed on a Germane Server running Windows Server 2K, SP4. It has quad Xeon 2.8 GHz processors with 2GB RAM. 4 300GB drives in a RAID 5 configuration.
I have created 2 databases which I would like to save, uninstall SQL, then reinstall it. (I didn't install it the first time.)
Then load the 2 databases into the new install.
How do I do this?
