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

I am using SQL Server 2005 and I have an endpoint that exposes some stored procedures as web-methods in the endpoint.
One particular stored procedure I have exposed takes a long time to execute: about 10 - 15 minutes. While, it is OK, that this stored procedure takes this long, it is not desirable for the HTTP Request that executed this proc to not wait for that long.
What I want to be able to do is to call the stored procedure and have the call return immidetaly but the stored proc continues what its doing. I will call another stored proc at a later time to retrive the result of the first stored proc. The first proc will store its results in a temp table. I am thinking of using SQL Server Service Broker to achieve this.
Is there a better a way to achieve this? And how does SQL Server process the Service Broker requests, i.e., I dont want the query to be executed when the server is busy. Are there any hints that I need to give to Service Broker to be able to do this?
Hi guys... I need to do some statistical reporting on the answers to registration questions. The answers are stored in pipe-delimited varchar fields to allow for one-or-many answers to a single question... here's an example:
Q: What are your fav colors? A: [checkbox list of colors]
Now the data is stored like this:
Reg001 ----------- red|blue|green|yellow
Now I need to determine how many people selected each individual answer, so like, how many people picked red, how many people picked yellow.... to report like this:
Red - 12 Blue - 23 Green - 15 Yellow - 9
What is the best, or suggested way, to go about splitting this data up and reporting on it? Can it be done in T-SQL, or will it need to be a combination of T-SQL and .Net language?
What's the best practice for adding / editing a record into a database with lots of fields ?I am not talking about the mechanics of it, as there are a lot of trivial examples using ADO.NET, stored procs, etc. Deleting is easy, you just pass in (a few) primary key/keys to uniquely identify the record. But in the real world when you have, say, a table with 100 fields! Do you code the INSERT sproc by hand, with 100 parameters... then call it with your ADO.NET code ? sounds like a lot of work to me... What about updating! That's even worst, sometimes you may need to update only 3 or 4 fields, but using sprocs you would have to pass the whole 100 parameters in again, and "update" the whole record (when in fact you are only changing 3 or 4 fields). With the update i could write different sprocs targeting only the fields i wish to update, but that sounds like duplicating work, vs having one generic update proc. Sometimes i just feel like bypassing sprocs and having inline sql as it would be less work... but i know it is untidy.. and more potential to be buggy. So come on guys (and gals)... let's hear your thoughts on how you would handle the insert / update scenarios when you have lots of fields ? Northwind examples are too trivial :-)
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
Hi,I have a problem to insert(update) a long text (more than 64K) intoSQL 2000 (datatype - 'text'). It cuts the data and insert only 64K.MSDN says: "When the ntext, text, and image data values get larger,however, they must be handled on a block-by-block basis. BothTransact-SQL and the database APIs contain functions that allow applications towork with ntext, text, and image data block by block." Could somebodygive me an example how to do this, please.Thank you
I have tab delimited text files which may have optional fields (meaning they can be not present at all) to the right of the required fields that I care about. It would appear that using a Flat File Connection with Delimited Format (tab) set will choke if it is initially configured with a file that has something like:
data data data
and it then encounters
data data data optionaldata
It chokes. I know this could be parsed line by line, but that seems silly. It seems like there should be a way to ignore columns beyond a certain point (e.g. Format "Delimited Ragged Right").
Is there some way to do this with a directly with a flat file connection?
I've two tables that I've made from some query subsets. Each table has a varchar field with notes/memos and I want to concatenate the fields into one long field.
The problem I'm running into is that when I run the query to check the concatenation, the field is truncated maybe 256 chars in.
I tried converting and casting the field as nvarchar 4000, and I've also done the same for the fields in the two tables, but that doesn't seem to help.
I can query for the fields from each table and none of them are truncated by themselves. It only happens after I concatenate them.
I've created a new table and inserted the results into it, but the field in it is also truncated.
Here is our problem...We are doing a lot of selects against a table that has one large fieldin it.If we do a select against all the fields except for description, thequery comes back relatively quickly. If we add that last field (768chars) to the query, our query takes 10x longer (5 seconds vs 56seconds.)When we run the one without the description column, we can watchperfmon and see a very quick spike to physical disk. If we add in thedescription field we can see that the server becomes I/O bound - thedisk sits at 100% until the query is complete.We have tweaked the min query memory setting for the server but itseems to have had no effect no matter how high we set it. Is theresome point at which MSSQL decides it cannot perform the transaction inmemory? What would I increase to cure this problem?For example:TMZDIFF int410WRITETIMEcharno 16System_Namecharno 64Timestampcharno16Name charno32Mount_Pointcharno32Size intno4 10Space_Usedintno410Space_Availableintno410Inode_Sizeintno410Inodes_Usedintno410Inodes_Freeintno410Space_Used_Percentintno410Inodes_Used_Percentintno410FS_Type charno8Space_Available_Percentintno410Name_U ncharno32Descriptionncharno768
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.
We have a proc that adds some fields to a few tables of ours and normally there are no issues. For one of our client databases this process is taking anywhere from 5-10 minutes to add the fields. This causes an issue where the app will timeout waiting. After plugging around and looking at the proc and trying different items i found it to only be for this one database and ONLY when there is data in the table. If i truncate the table and run the same procedure everything is fine. Tables all have same index on 4 columns and the columns being added are not indexed because of the stupid hoops we have to jump thru to pre-pivot data for our reporting package.
I have followed many tutorials on selecting and replacing text in text fields, varchar fields and char fields, but I have yet to find a single script that will to all 3 based on field type. Let's assume for a moment that I don't know where all in my database a certain value that I need changed resides ... i.e., the data's tablename and fieldname. How would I go about doing the following ... or more importantly, is this even possible in a SQL only procedure?1) Loop over entire database and get all user tables2) Loop over all user tables and get all fields3) Loop over all fields and determine the field type4) switch between field types and change a string of text from 'a' to 'b'Please be gentle, I'm a procedure newb.
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.
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?
I have a challenge and am not very versed with coding this situation. The situation is I am trying to put long text (more that 255 char) in a ntext field in SQL7, but the max char can input is only 255. Anyone can advice on how to put in more that 255 char in a field as well as how to select back the record whice more than 255 char.
Please give advice if you encounter this problem before.
Anyone have same sample on how to put in and retrive long text (more then 255 characters). Please Comment.

You should use readtext and writetext to access text column. By the way, nchar and nvarchar can hold up to 4000 characteres.

How long exactly is the text datatype in non-unicode characters for SQLS7? I guess I need to find out how long my input is and break it up into multiple text fields, but what's the max length?
I have tranferred my database from Access to SQL. In some cases where there is a very long text in the field of "content" (thats the name of the field) appears the sign <Long Text> while in some other fieldsof the "content" the text appears normally...
I have used ntext 16 as a datatype... How can i dissapear this sign from the field...is there any way?? Thank you
I have a data table in my project that has a "text" (not varchar) field in it. I am trying to load this field with little paragraphs of text for showing on my pages. How do I get the free text loaded into the table? The database explorer and all the data grid controls cut the text off at one line. There doesn't seem to be any way to get multiline text into this table.
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.
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 have a textbox field that take 2000 characters from user..Then I used a store procedure to save that user input into database through an insert statement, but for some reason it just never store the whole string of 2000 characters but only store some of it (like 100 or something) .. Seems like a data type problem…(I am using SQL server 2000)
i have a table in sql server, i want to insert a long text for a field. that long text like a file's text.please tell me what is the data type for that field. i tired ntext and text data type but i cant insert long text values. reply me if u have answer
I have a database table that is populated by bulk insert of a text file. This file is not comma delimetated and there are no line end characters, just one very long string, although the file is fixed length.
As I said I now have this long string in my SQL Server 2005 table. Is there a fast way to split this up into multiple rows?
Say for instance I have a string of 100 characters and each row would be made up of 10 characters. Is there a easy way to split this into the 10 rows or 10 characters using just a SQL statement?
Newbie here, just wanted to get that out of the way first and foremost.
Im trying to set up a DB in SQL 2000 that allows me to enter lots of text into a column.
I read one site where it said to use the NTText datatype with a length of 16. I did that, but everytime I enter alot of text into that column I get <Long Text> and I dont know how to output that or even read it.
Do any of you guys know how to either:
1. get the text out of the <long text> or 2. a better way to store that much data.
Hi,I asked this in an MS Access newsgroup, but no one has answered. Since italso applies to SQL Server, maybe someone in here has an answer? I actuallydo have the same problem in both SQL Server 2000 and Access 2000.When I click in certain records in a memo field, I get the error message"text too long to be edited", and I can't get into the record to make anychanges.I tried exporting the record to html, but only part of the memo field isexported.I know that in SQL Server, you can increase the size of the field, but youcan't do that in an Access memo field (that I know of!).I'm thinking that if I could get into the field and lose some of the whitespace, it would help, but I can't get into the field, and can't get the dataout, either!Does anyone know anything about this?Thanks, Jill~

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.
