Function That Replaces Ntext And Compares Ntext With Nvarchar

Nov 28, 2007

I am running this query to an sql server 2000 database from my asp
code:
"select * from MyTable where
MySqlServerRemoveStressFunction(MyNtextColumn) = '" &
MyAdoRemoveStressFunction(MyString) & "'"

The problem is that the replace function doesn't work with the ntext
datatype (so as to replace the stresses with an empty string). I had
to implement the MySqlServerRemoveStressFunction, i.e. a function that
takes a column name as a parameter and returns the text contained in
this column having replaced some letters of the text (the letters with
stress). Unfortunately, I could not do that because user-defined
functions cannot return a value of ntext.

So I have the following idea:
"select * from MyTable where
CheckIfTheyAreEqualIngoringTheStesses(MyNtextColum n, '" & MyString &
"')"

How can I implement the CheckIfTheyAreEqualIngoringTheStesses
function? (I don't know how to combine these functions to do what I
want: TEXTPTR, UPDATETEXT, WRITETEXT, READTEXT)

Hello,

I need to save some news text in an SQL table. The text can be long.

Moving Ntext To Nvarchar(max)

May 24, 2006

I just move our SQL server to version 2005. In new version ntext field is deprecated and documentation says that ntext(max) should be used.

If I have table Table1 and ntext column Column1. When I execute following SQL statements:

alter table Table1 alter column
Column1 nvarchar(max)
go

1.) Are out of row data automatically move to in row?
2.) Or should I also execute something like this ?

update Table1 set Column1 = Column1+'' where Column1 is not null

3.) Is there way to check if data is stored out or in row?

Best regards
edvin

Ntext Versus Nvarchar

Feb 19, 2008

Hi,

my question concerns both desktop and device apps.

I'm using sql compact to store some data. I often have to store strings (descriptions, url, etc.) but I don't know when to use nvarchar or ntext.

Nvarchar needs to have a size limit, but I often set it to 8092 when I don't know the actual limit (urls can be very long !).
I fear Ntext because I suppose there is performances impact.



Is there any "rules" to help to choose which data type I'd use ?

Thanks,
Steve

Convert Ntext To Nvarchar For ORDER BY?

Jan 22, 2005

I need to sort by an ntext field, but it won't let me do it.

However, if I cast the field as nvarchar(100), I can use ORDER BY on that.

Is there any reason that this is a bad idea? In my testing, ordering by a converted ntext field was actually *faster* than ordering by an nvarchar (same data in the fields).

Ntext + Nvarchar - Will This Improve Performance?

Jan 28, 2004

Hi all

I have a table that contains an ntext column for storing values up to a couple of Mb in size.

However, I estimate that 95% of the values stored in this ntext field will fit into an nvarchar(4000) field.

Is it worth me having both fields in the table?

i.e. For rows where the values < 4000 characters I would store the value in the nvarchar column. Otherwise I would use the ntext column.

Can anyone confirm whether this technique would increase performance given that ntext values are sort of stored separately to the rest of the table data?

A colleague of mine is an Oracle DBA and he mentioned this technique is fairly caommonly adopted in the Oracle world.

Thanks
Matt

Unicode Is Nvarchar, Ntext, Nchar

Apr 10, 2008

When I tried to insert armenian by doing the following
insert into tablex (field1) values (N'testdata')
it does not display in query analyzer or in the database as armenian.
When I copy this to word it does not convert it.

What else am I supposed to do to get that information to redisplay the correct way and I would appreciate any tutorials or samples you can show or direct me to.

Change Ntext To Nvarchar(max) In A Live Database

Oct 19, 2006

I have a live SQL 2005 database that has ntext fields, when the ntext fields go over 4000 chars the record can no longer be edited. It throws a string or binary data would be truncated error. I tried turning text in row OFF, but it did not work. Can anyone forsee any problems with changing the ntext fields to nvarchar(max) in the live database? Also, I came across sp_tableoption N'MyTable', 'large value types out of row', 'ON', does this work for ntext also? sp_tableoption N'MyTable', 'text in row', 'OFF' did not do anything.Any help would be appreciated.

What Are The Cons And Pros Of Using Nvarchar(max) Versus Ntext?

Apr 4, 2007

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?

NTEXT Vs NVARCHAR For Large Number Of Columns

Jul 23, 2005

Hi all,I need to store data into about 104 columns. This is problematic with MSSQL, since it doesn't support rows over 8kb in total size.Most of the columns are of type NVARCHAR(255), which means we can't havemore than 8092/(255*2) = 15 columns of this type.With a row length of more than 8kb, SQL gives a warning that any rows overthat amount will be truncated.So far I'm seeing two possible solutions to this problem:1. Split data into multiple tables with the same ID column accross alltables, and then join them on SELECT statements.2. Use NTEXT instead of NVARCHAR. NTEXT's length is 16 bytes because itcontains a pointer to the actual value stored somewhere else. However, NTEXTdoesn't support regular indexing, only through a Full-Text Index catalog. Inthis case I'll need to user "WHERE CONTAINS(columnName, 'sometext')" toperform searches, which is bearable.I'm inclined toward #2. However I haven't used Full-Text indices before anddon't know their limitations. Will I run into problems with NTEXT? Is therea better solution?Thanks.-Oleg.

Ntext Vs. Nvarchar, Mysterious Data In The Database

Oct 2, 2007

I hope this is the right forum for this question, my apologies in advance if it isn't....

We have a web based CGI product (written in C++ VS 6) that uses ODBC and takes text from a submitted web page and stores it in a SQL Server table in a field of type "ntext". The user in question is copying and pasting this text from an MS Word 2003 document. After the initial save our app errors out trying to access the table it just wrote to, and when we look in the table we see that up to **200 carriage returns** have been mysteriously inserted into the ntext field!! (Our product has been out in the field with no such problem for several years, so we are thinking it's related to something specific the customer is doing - perhaps with using MS Word for the source text.) We have tried but cannot duplicate the problem, but the customer sees it with each attempt to modify the table in question. The only thing that I see out of the ordinary is that the field in question is of type "ntext" - which supports unicode, instead of nvarchar. Does any of this ring a bell for anybody? I'm thinking of changing the field type to nvarchar to see if that solves the problem.
Thanks, Steve Bradbery

Wild Search NText And NVarChar In Parameterized Inline Statement

Dec 14, 2004

I want to retrieve data from SQL containing non English character but fail, can anyone shed me some light?

What I use currently:

Dim strSQL As String
strSQL = "SELECT ArticleID, "
strSQL &= "ISNULL(Body, '') AS Body, "
strSQL &= "ISNULL(Subject, '') AS Subject "
strSQL &= "FROM Articles "
strSQL &= "WHERE (Subject LIKE N'%' + @Keyword + '%' OR [Body] LIKE N'%' + @Keyword + '%') "
Dim con As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim cmd As New SqlDataAdapter(strSQL, con)
cmd.SelectCommand.Parameters.Add("@Keyword", SqlDbType.NVarChar).Value = keyword
...


I'm not so sure where should I place the letter "N", I use :

SELECT ArticleID,
ISNULL(Body, '') AS Body,
ISNULL(Subject, '') AS Subject,
FROM Articles
WHERE (Subject LIKE N'%SomeNonEnglishString%' OR [Body] LIKE N'%SomeNonEnglishString%')

in Query Analzyer, it works! But it failed in my program... oh my god...

Thanks a lot!

Using NTEXT

Dec 22, 2003

I wonder if I should do something to the data I store on ntext fields

so far it looks like it has no problem holding special chracters (as it should B for unicode)
anyway - is there some combinations I should avoid ?

Should I use something like on old ASP Server.URLEncode() or Server.HTMLEncode() ?

Ntext Value

Mar 6, 2004

hi all,
I am new to sql server.
I need some help regarding ntext value.I am using an insert stored proc to insert the value into ntext field, till now i have been using a varchar variable to pass the value. but i think this doesn't work when the size exceeds the limit of varchar and also what if i want to perform group insert?
and the major issue i am concerned about is, i don't want to update this field quite often.I need to check whether the existing ntext value and the new value which i want to insert are different.I want to do it in a better way than processing both values entirely.I want to make sure that the update statement is executed only when both values differ.

Problem Using Ntext

Jun 20, 2006

Hi, I'm using a column (ntext) to store some long strings. An example of the string that I need to store is the following:

436;Implementing A Gang - Awareness Program/And A Middle School
Gang  Prevention Curriculum. Doctoral Th;Samuels;Donald J;Miami
IV;Administrators; At Risk; Child And Youth Studies; Community;
Community Members; Drop Out Prevention; Educational Leadership;
Law/Criminal Justice; Peer Counseling; Principals; Secondary Education

I wrote a store procedure that does it, but it seems that the column
space is not enough for the above string. The string in fact, is
truncated and only the following portion is stored in my table:

436;Implementing A Gang - Awareness Program/And A Middle School Gang 
Prevention Curriculum. Doctoral Th;Samuels;Donald J;Miami
IV;Administrators; At Risk; Child And Youth Studies; Community;
Community Members; Drop Out Prevention; Educational Leadership

What can I do?

Ntext Problem

Aug 15, 2001

I am working in asp and using sql server 7. I have a section where the input is to long to use a char field so i had to set the field as ntext. Now i am trying to do a section where i wanna look and see if the field is null and if not then it is to perform an operation. If it is null it is to skip and go to the next field in the record. However it is not performing this operation. It sees the first field and does pass the second one because it is null. If i put in a character into the field it will go on until it gets to a null again and then stops. Any suggestions?

NText Field In SQL??

Jan 15, 2004

Hello All,

Maybe a stupid question but I'm new to the db admin work so please bear with me.

I've imported an Access db into SQL, in the Access db the field type was 'memo' to accomodate the large amount of text (on avg ruffly 4100 chars. with spaces). Now in SQL the field in the table I have set up as an ntext field, which I understood to be equivalent to a memo field in Access.

My problem is when saving data to the field the first time it saves all the data correctly with the exception of the field in question. The data in the field is '<LongText>', now when I try to update the data in the table I get a 'Data Truncated' error message and no update takes place throughout the table.

After testing this and trying different things, I've found that if I shorten this one field and try to save to the db I still get the 'Data Truncated' error message. If I shorten the data in the field AND delete the record from the SQL table then it will save just fine from there on out (which won't work for the reports).

I'm not sure what I'm missing here to get this to work the way it did in Access.

Ntext And AppendChunk In ASP

Jul 20, 2005

Hi all,I have an asp page that writes to an ntext field in SQL Server 2000.All was going well until I had to put in a section of text greater than 8000bytes.Then I got a timeout error and the update wouldn't go through.After reading that 2000 only accepts chunks of 8000 bytes or under at atime, I attempted to use the AppendChunk method.The code I wrote seems to work first time I enter text in the page, nomatter how big. But when I try to update the ntext file,if it is more than 8K, it just sits there and nothing happens. Now I donteven get a timeout error.From what I read, I was assured this would work.For small text files under 8K it works beautifully, I can add and removetext and it all works fast.But as soon as the ntext field gets beyond that size its totally unworkable,and seems to be just the same as using the standard UPDATE method. I'veattached the code.If anyone has any suggestions I would be eternally grateful, this is drivingme nuts. I've attached the offending code.ThanksBill' ***********************************************' * PageStatus: SAVE Action: EDIT *' ***********************************************IF PageStatus = "SAVE" AND Action = "EDIT" THENsqlc = "SELECT * from " & tblNameDim FldValDim rsSet rs = Server.CreateObject("ADODB.Recordset")rs.cursortype = 1rs.cursorlocation = 3rs.locktype = 3rs.Open sqlc, oConniChunk = 254cTxtDescription = SQLReady(FileUp.Form(lang))For iNo = 1 to len(cTxtDescription) step iChunkiStartAt = iNocWorkString = mid(cTxtDescription, iStartAt , iChunk )Response.Write "At byte " & iNo & vbCRLF & "<br/>"rs.Fields("SimpleChinese").AppendChunk(cWorkString)NextIF Page_Err = "OK" THEN' Perform the Queryrs.Updaters.CloseSet rs = NothingSet oConn = NothingEND IFEND IF

Ntext Question

Jul 20, 2005

Dear GroupI admit, this might be a very ignorant question.BOL says about the ntext data type:Variable-length Unicode data with a maximum length of 2^30 - 1(1,073,741,823) characters.I've stored a string consisting of around 45.000 characters in a ntextfield - done by copying the string in my txt document and pasting inEnterprise Manager.When I determine the datalength of the field in SQL Analyzer I get2046.Is this realistic? Is it bytes or the actual number of characters? Itseems incrrect to me..Although, when I read the string with a DataReader based on a storedprocedure and save it in a string variable in my VB.NET application,the string is truncated, although the variable can hold up toapproximately 2 billion Unicode characters according to MSDN.I just wonder whether I've done something wrong or misunderstoodsomething on the SQL server side that causes this problem.Thanks very much for your help!Martin

The Joys Of NText...

Sep 11, 2007

So, here's the conundrum.

We have ProcA that uses nText as one of it's parameters. It works fine.

I'm writing ProcB, that calls ProcA and also accepts nText as a parameter.

Unfortunately, I have to do a string replace in that nText field. But, I've got that sorted out, with a little UPDATETEXT voodoo.

My input parameter, now exists unchanged as @Body and in #nText.txt with all the modifications completed.

The problem, is I need to pass that #nText.txt value as a parameter to ProcA.

I can't use 'SELECT @Body = txt FROM #nText' because I get an assignment error (can't assign nText values).

And I can't seem to call ProcA with the value from the table directly.

What can I do? I'm 99% there, I just need to take this last step and I can put this garbage behind me.

Thanks
