Hello, I am looking at encryption in SQL Server 2008. I have the basics down but have a question about sizing the encrypted column.
I have two columns of data I want to encrypt. One 9 characters and one 20 characters. Currently VARCHAR(9) and VARCHAR(20). (Yes I know that the VAR means space savings.) What is the minimum VARBINARY needed for these, or a better question how do I calculate the VARBINARY size?
Thank you,
djj

Two suggestions.
1. SQL Server 2008 has built in encryption, why not use that?
2. Why not simply do a few tests to determine what size you need?

The built in encryption is what I am looking at, at least I am using the BOL how to.
As to the tests I will do that but it would be nice to have an equation to calculate it.

I am using SSRS 2008 in my application. For some items the item description contain the data as "5X7" DISNEY POSTCARD" in database. When I do the export to csv file in SSRS 2008 the text displayed as "5X7 DISNEY POSTCARD"" in csv file, it is placing the double qoute at the end of the text instead where it should be.
Please any one help me on this, I am running out of time.
Thanks in advance

You have a problem that is probably not solvable, CSV/Excel/MS converters use the " character as the text delimiter and probably wraps the entire text field in ". Embedded quotes are probably not going to be supported, certainly in CSV where it is a control character.

While doing a little maintenance on a database that keeps track of reclosers (devices used in electrical substations), I tried adding a field to a table using the Management Studio on the server. No go - I don't have permission, and have no idea where to change that. So I switched to the client, opened Visual Studio, connected to the same database on the server, and proceeded to add new fields without a problem. In both instances I was logged in as the same domain user, with admin priveleges. It's not intuitively obvious to me why a remote user using Visual Studio has access priveleges greater than an administrator on the local server using the management tool designed for SQL Server. Can someone explain this odd behavior? I really think - especially once I complete an app to use this data - that this situation should be reversed, but I have no idea how to do so.
Thanks!

i understood the first part of your question but got lost in the last question. First Question when you logged into SQl management Studio did you use Windows Authentication to log in ? if yes, your user did not have permission. log in as a "sa" user or a user that has sysadmin permission in that sql instance and add the domain user and give him appropriate permissions and you will be able to add the field there. Your Resolution was to go the VS route which is not a good idea in most cases.the Reaons that you were able to add the field was that someone with permissions once created that and now it is always there it does not even ask you for username and passowrds, you just use it. i used to do that too. The last part of your question i did not understand

Vuyiswa Maseko,

If you are very sure that you used the same credentials in both instances, then it could be a setting in SSMS that prevents changes to tables that require the table to be recreated.
Click Tools --> Options
Under Designers --> Table and Database designers, there is an option "Prevent saving changes that require table re-creation".
Ensure that this option is unchecked. It is checked by default.

Thanks!
I generally don't mess with default settings until I'm familiar with the product, and that's one I haven't changed.

Had the same problem today. I am getting into 2008 from 2000 and did not know where to find that setting.
Thanks Shameel
by the way I just noticed the Get Smart quote

I'm on a roll here, so bear with me.
I haven't used it before, and want to learn it quickly. I particularly want to use it with C# applications for tracking equipment and service records for work. I also happen to have a few bucks available and I'm in the mood to buy myself a Christmas present. A book would be nice, particularly a book that covers programming for SQL Server 2008 in C#, and which will also teach me about n-tier development - breaking the task into logical units for data access, business rules, and user interfaces. I tend to get them all muddled together in one mess, and you know what that leads to... another project I never finished. I'd like to be done with that, once and for all.
Any favorites?

[edit] As Shameel pointed out these may be illegal books and I respect and appreciate the work put in by authors to encourage theft. [/edit]

I did not even look into the details, I got the link right here and thought they were teaser type books, thanks for the heads up. I agree with you and the authors put in way too much effort for me to devalue their work by encouraging theft.

I appreciate your conern, and agree with you about IP theft colpletely, but if you couls at least post the title, I might be able to actually buy it.

Great! That's a good start, I think, although I don't plan to use web access yet - just a dedicated C# client accessing a central SQL server in the office. My whole plan is to make this equipment tracking job so simple I can hand it off to someone else.

Is there such a thing? Access ships with a built in documenter, which I find handy in print form to use as a reference when I'm trying to wrote code to manipulate it. I never can remember all the field names and types 20 minutes after I create a database...
I can get a list of field names using a select query against 'information_schema.columns' and I can print that, but it's not a very convenient format; all I want is the field name, type, and width (for text).
Is there a freely available tool to simplify this task?

There's an article right here on the Code Project which might help:
SqlDoc: Document your SQL Server database[^]
Or, a quick google for "sql server free schema documentation tool" brings up over 85,000 results, at least one of which might be helpful.
DBScribe is good, although it's not free. But at just $99 it's not exactly going to break the bank. It might be overkill for what you're looking for, though.

I want to send someone an MDF and LOG file, have them attach the file to their server, then script out the entire database and return the script to you.
