I want to store IP number in a column in db but which column type should I use? Of course I can use string but isn't this a waste of storage space? Can I not store IP nr in another type in db that saves space?

1. I want to show a zero in front of all number. Actually i added but it doesn't show.

P.S. The columns with numbers have checked "allow nulls".

View 5 RepliesI wanted a formatted text to be converted into unformatted text in the UI . for that I did the following
String strInput;
String strOutput;
strInput = txtEditorAnswer.Text;
strOutput = Regex.Replace(strInput, "<[^>]*>", String.Empty).Trim();
txtEditorAnswer.Text = strOutput;
txtEditorAnswer.Text = Server.HtmlEncode(txtEditorAnswer.Text);
but as it changes the value in the Database also, so its creating a problem for future. Now I need to change the text after being inserted into the database.
I am developing a asp.net application and i am using SQL Server 2008. I took a IDENTITY column as Record_ID for detail table where i will have trillions of records per year. So just want to ask whats the largest number record id (identity) column can hold and in ASP.NET which data type i should use to handle record id as i am using this id as a reference to update the table data. I don't want to end up being trapped some day.
View 1 RepliesI have a column with nvarchar datatype storing the date. I am using a Gridview to display and edit data of that table. Now when I update the table the nvarchar column containing date in the format mm/dd/yyyy gets converted to Jun 9 2010 12:00AM format. I don't want this to be happening. I don't understand why this is happening as I don't have datetime column.

View 2 Repliestitle isn't as detailed as I hoped but I have a few questions. Traditionally I've always been a mixed mode person, storing PDFs and other things into the file system with pointers from my SQL DB to them.
Recently I've heard more people storing files into the DB directly and wonder if I'm storing files around 100-200MB in size, will I run into a lot of issues? Are there ways to compress the files other than perhaps zipping them up and storing the zip?
Finally, something I've always wondered about but never really found a good work around for... if I decided to continue with the mixed-mode storage solution, and these I need to retrieve these files for use on a website, how do I secure these files so that someone can't just randomly come and retrieve these files off the server by guessing files names, etc?
I did one work around once where I stored a set of PDFs to a non-web directory like c:pdf and setting permissions for the web account to access them. This allowed me to retrieve them using the references in the DB and provide some garbled filename so people couldn't retrieve it themselves but this all seems rather complicated.
I have a File Uploader in my ASP.NET application Using C#, we can upload any type like images, documents, pdf etc.
I m storing it in the Filesystem and having only the Name of the File in DB.My doubt is can we store the entire file, images in DB. State me Which is good practice and why we need to use it.
Either file System Storage or SQL DB Storage.

Have a question about the best approach for file storage in a SQL database. I have a table called Widgets, and each row in the Widgets table can have multiple files. I also have another table called Extensions, and again each record in this table can have many files.
Here is what I am considering:
Approach #1:
[Code]....
That approach is very simple and easy to use, but I feel that I could merge the two file tables into one, then use lookup tables:
Approach #2:
[Code]....
The thing is, there are no duplicate or shared files between the two types of objects. So even though I feel better about approach #2, I am concerned that I may be adding additional complexity (and using more server resources to perform the joins), than needed.
I'm using Cute Editor for ASP.NET for the first time, and it's occasionally refusing to insert or update a record. Basically the records are just composed of a bunch of HTML and text. So far I can't detect a pattern to the problem and I'm wondering about my data type.
I tried VARCHAR(MAX), NVARCHAR(MAX), and NTEXT, doesn't seem to fix it.
So what is the best SQL data type for HTML?
And could that be causing CuteEditor to refuse to insert/update records? Or something else?

View 7 RepliesI am designing an prototyping an app the needs to store images, similar to facebook. This will be a public facing site and I am not sure how many users I will end up with but what I am looking for is a way to efficiently retrieve them.
So far I am thinking of storing them in SQL Server varbinary columns. I have the upload code and the storage code for that. My concern is retrieving them. I can retireve and build the image tag on the fly but I am worried about having to hit the database for each one.
I have been thinking about getting all images for a user and caching them in the asp.net cache for 10 to 30 seconds. I have never had to do something like this so I would be interested in hearing a few different approaches. Obviously the images can vary in size and I was thinking about defining a size limit, but I haven't gotten that far yet.
