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).

I am running this query to an sql server 2000 database from my aspcode:"select * from MyTable whereMySqlServerRemoveStressFunction(MyNtextColumn) = '" &MyAdoRemoveStressFunction(MyString) & "'"The problem is that the replace function doesn't work with the ntextdatatype (so as to replace the stresses with an empty string). I hadto implement the MySqlServerRemoveStressFunction, i.e. a function thattakes a column name as a parameter and returns the text contained inthis column having replaced some letters of the text (the letters withstress). Unfortunately, I could not do that because user-definedfunctions cannot return a value of ntext.So I have the following idea:"select * from MyTable whereCheckIfTheyAreEqualIngoringTheStesses(MyNtextColum n, '" & MyString &"')"How can I implement the CheckIfTheyAreEqualIngoringTheStessesfunction? (I don't know how to combine these functions to do what Iwant: TEXTPTR, UPDATETEXT, WRITETEXT, READTEXT)

Hello,
I need to save some news text in an SQL table. The text can be long.
1. Should I use nvarchar(MAX) or nText?
2. And what is the difference between nText and Text?
I am using SQL 2005.
Thanks,
Miguel
Dear All,
i'm trying to convert the datatype from ntext to nvarchar.i'm getting error. is it not possible?
Vinod
Even you learn 1%, Learn it with 100% confidence.
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

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
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

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.

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.

Does it have something to do with having to enable full text search perhaps in the latter case?
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.

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.

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!

View 5 Replies View RelatedI have a scenario to sort on an nvarchar (50) field and I need to keep any changes to the sproc in the ORDER BY clause if possible. This field will contain strings such as...
abc-217c, abc-15a, abc-9a, abc-7b, abc-17ar, etc...
The issue I'm having is when the records are sorted, they are returned as...
abc-15a, abc-17ar, abc-217c, abc-7b, abc-9a,etc...ordering numerically on the first numeric character in the string ie, 1,1,2,7,9)
However, I need the numeric component to be treated as a whole number and order in this fashion...
abc-7b, abc-9a, abc-15a, abc-17ar, abc-217c (7,9,15,17,217, etc)
I feel pretty sure that this issue has come up before...can anybody provide a working example that would provide a simple(or not so simple) solution?

Hi guys, how are you? I was wondering how I do to convert int to nvarchar and vice versa?
Thank you very much.
Hi everyone.
So as the subject says, I have a few fields that are nvarchar but hold date information. Most of these fields I have been able to move to datetime easiliy enough, simply by going into edit mode for the table and converting the fields to datetime. But 1 field is giving me problems I keep getting this error.
quote:- Unable to modify table.
Arithmetic overflow error converting expression to data type datetime.
The statement has been terminated.
I really dont know why I'm getting this error, but I"m assuming it may have to be something like one of the records may not be in date format. But I don't know if this is the case and I don't know how to locate where my problem is coming from.
Any guidance is greatly appreciated.
Thanks.
I have the following code:
INSERT INTO Reports_PI_Recent
SELECT TOP(13)* FROM Reports_PI
ORDER BY RecordKey desc
problem is that the data I am trying to insert is of the type nvarchar. eg: 06.50
I need it to be converted to type decimal (or float) before it is inserted in the new table.
Is there a way to do this within the SELECT TOP expression?
I'm new to SQL so please walk me through this step by step.
All the columns in my table have a data type of nvarchar, however, some of them need to be changed to decimals.
Here's an example of what my table (cicc.972file) looks like now
Account nvarchar(8) Balance nvarchar(8) Percent nvarchar(5)
45678935 459600 03500
78965215 005643 10000
and here's what I need it to look like
Account Number Balance Percent
45678935 4596.00 0.3500
78965215 56.43 1.0000
This seems like it should be ridiculously easy, but I keep running into road blocks. Like I said, this is just a sample from my table. My real table has 90 columns in it and about half of them need to be changed to either a dollar representation or a percent.
Thanks for you help!

I have imported a text file with various data into sql table. all these values have been imported as nvarchar. I need to convert these into Integer. the format of the values is 10length i.e. 0000000.00.
example of data:
0001028.99 - needs to be shown as 1028.99
222.00 - needs to be shown as 222.00
0000190.89 - needs to be shown as 190.89
2708.99 - needs to be shown as 2708.99
00000-50.99 - needs to be shown as -50.99
-109.79 - needs to be shown as -109.70
as you can see some of the values have leading zeros and some don't.
i have tried converting from nvarchar to int and i get the error cannot convert nvarchar to int, i believe it may be because the data contains negative values as well as positive values.
Is there a split function or position function which i can use to extract the data? or any other methods which i can use would be really helpful.
Thanks
