How To Compress Text Before Storing In DB?
Feb 15, 2005
I was planning on running a service where thousands of text messages are stored. Obviously I'd want to make the most of my DB space, and was wondering if there's some way for SQL to compress text down to the smallest space possible. If not, is there some kind of ASP component I could download to do this? Failing that, I could always write a simple one, which takes the most common letter combinations, and shortens them down to a single character.
Any advice?

Hello,
In SQL 2005, what is the best way to take a text file and store it in a table field, then later extract that file to a directory with original name and format intact?
Thanks!

Hey folks,
Just a quick question to ask what is the best field to store the data held in a rich text box/control. Just want to make sure that i get it right first time you know. Not sure about the amount of characters that needs held but its going to be quite a lot as this field shall contain most of my pages content.
Appreciate any help
Thanks

Hi Everyone,
I have a simple webform with a text box with multiline enabled and a submit button, in vb.net. Inside the text box, when you are typing text with let's say adding carriage returns, spaces etc. How to i save the text to a database? By that, i mean, how to i declare the column in my database, varchar, text ...?
Also, when retrieving the saved text back to the textbox, will it keep the formatting because that's what i am trying to do? Or, what is the best way to keep text formatting in a database?
Thanks for the help,
Kevin

Hi!I want to store some really big text in my database (for my articles). The approximate size will be from 500 to 40000 characters. I was thinking of using the database 'text' datatype.I have heard that reading these text fields is slower and decreases the performance. Moreover is it advisable to index this for searching purposes?

I'm sorry, but I'm a definite newbie. How can I store really long pieces of text other than as the 'text' datatype, which is too short in SQLS7?
Please help! It's key to my site admin system for importing third party wysiwyg-generated pages into our system....
Thanks,
John E.

The error I recieve is as follows:
"[Flat File Destination [13]] Error: Data conversion failed. The data conversion for column "SDATA" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.". "

I am selecting data from an OBDC then copying it to a text file an I always get this error, but when I change the destination to a excel file it works perfectly. But the whole point of the package is to copy to a text file.
Please could you help me, your replies will be greatly appreciated.

This may be a stupid question but I can't find an easy answer for what Iwant to do. I need a blob data field that can store both binary and textdata like the sql_variant field. I am using vb.net to populate a sql table.I want to store both string and binary data.

As we all know, there is a 8060 bytes size limit on SQL Server rows. Ihave a table which requires a number of text fields (5 or 6). Each ofthese text fields should support a max of 4000 characters. We currentlystore the data in varchar columns, which worked fine untill ourappetite for text fields increased to the current requirement of 5, 6fields of 4000 characters size. I am given to review a design, whichesentially suggests moving the text columns to a separate TextFieldstable. The TextFields table will have two columns - a unique referenceand a VARCHAR (4000) column, thus allowing us to crossreference withthe original record. My first impresion is that I'd rather use the SQLServer 'text' DB type instead, which would allow me the samefunctionality with much less effort and possibly better performance.Can anyone advise on advantages and disadvantages of the two optionsand what the best practice in this case would be.Any advise will be well appreciated.Tzanko

Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?

I have a SQL 2012 enterprise server, and I'm using Commvault as my backups. So commvault can restore a .bak file to my server, but it cannot use sql compression on the file apparently. So what would be a 150GB .bak backup file is now 600GB. I have to manually upload these files to an auditing firm on an sftp server and the transfer times are now huge.
Is there a way to use something in sql to compress this already existing .bak file down?

Is there any improvments in SQL 2008 backup methods such as spliting backup files in manageable size(s), compress the backups and/or improving the speed of backup?
Though there are "commercial" tools available, it would be nicer if Microsoft SQL team can incorporate some core needed features in these areas for Small/Medium size businesses.
This is not a question but a suggesstion.
Thanks

Hey everyone,
I have an issue where i am sending out files with 30,000+ lines and they are reaching the 11mb, 12mb in size.
This is becoming and issue for us, as we are only allowed to email up to 10mb in size.
I have tried reducing all spaces in the data, removing any graphics etc from the report , but still the excel file is over 11mb. One thing i did find was that, if i export it to excel, then open the file and save as a different file name the file size drops 50% !!
I was wondering if anyone has been able to zip/compress the exported file before it gets emailed?
It would be a great feature for MS to include in the next service pack.. Take advantage of the built in Zip support in Windows..
Look forward to hearing any suggestions that the community may have,
Thanks
Scotty

I got this situation where my network admin observerd that there is a high network utilization between 2 nodes in our AG (the primary node & the DR site, 2 separate locations of course); then he advised to compress the data transfer between those 2 nodes as the previous DBA already did that before!
Ok, I have no clue about this, so decided to google it, got nothing. My backup is already compressed through some third party app (just in case if that matters to the subject).

Currently we use a SQL maintenance plan to do a full backup of all our databases daily (about 40 databases on our production server). As you can imagine, this eats up disk space quickly so currently we manually zip the backup files and/or move them to an archive drive. I considered writing an application to walk through the backup folder structure and zip any .bak file it finds, but I know there are some third party tools out there that will backup/restore a MS SQL database.
I was wondering if any of these also zip the backups once they are created. Any recommendations or suggestions are welcome.

I need to store a user ID of whoever made the last change to a record in a table. I have added a field with a default set to 'suser_sid()'.
Is it wise to store SID's in a database table if you are using NT authentication? My concerns are that if the user is deleted by the NT system administrator then I lose data integrety also if the database is backed up and restored onto a different machine with different users it won't work at all.
I'd be grateful for any help with this.

Hi, i'm trying to do a full text search on my site to add a weighting score to my results. I have the following database structure:
Documents: - DocumentID (int, PK) - Title (varchar) - Content (text) - CategoryID (int, FK)
Categories: - CategoryID (int, PK) - CategoryName (varchar)
I need to create a full text index which searches the Title, Content and CategoryName fields. I figured since i needed to search the CategoryName field i would create an indexed view. I tried to execute the following query:
CREATE VIEW vw_DocumentsWITH SCHEMABINDING ASSELECT dbo.Documents.DocumentID, dbo.Documents.Title, dbo.Documents.[Content], dbo.Documents.CategoryID, dbo.Categories.CategoryNameFROM dbo.Categories INNER JOIN dbo.Documents ON dbo.Categories.CategoryID = dbo.Documents.CategoryID
GOCREATE UNIQUE CLUSTERED INDEX vw_DocumentsIndexON vw_Documents(DocumentID)
But this gave me the error:
Cannot create index on view 'dbname.dbo.vw_Documents'. It contains text, ntext, image or xml columns.
I tried converting the Content to a varchar(max) within my view but it still didn't like.
Appreciate if someone can tell me how this can be done as surely what i'm trying to do is not ground breaking.

Hello everyone !
I want to perform Full Text Search with SQL Server 2000. My documents (.doc, .xls, .txt, .pdf) are stored in a SQL Server field which is binary (the type of the column is image).
I would like to know, how you can extract pieces of text from the documents.
Example:
I have a ASPX page with codebehind in C# making the search in a table in SQL server that is full text indexed.
I make a search looking for the word "peace", than SQL server will take care about the search and return it to me the rows that match with that. But also I'd like to extract the 50 characters before and after where sql server found the word "peace" to show in the result page.
Does anyone has any idea how to work around it ?
Best regards.

Hi,
Im a programmer for an university webportal which uses php and msssql.
When an user creates a new entry and his text is too long the entry is cut short and weird characters appear at the end of the entry.
For example:
http://www.ttz.uni-magdeburg.de/scripts/test-messedb/php/index.php?option=show_presse&funktion=presse_show_mitteilung&id=333
How can I set the text limit to unlimited?
Could it be something else?
Is there a way of splitting an entry to several text fields automatically?
Thanks in advance for any help you can give me,
Chris
