Manipulating Large Ntext Data With ADO Recordset

I am having a problem writing a large amount of ntext data to a field within an ADO recordset. I am using the append chunk method but it does not seem to work. The SQL 7 field will hold the data its only about 60K.

Manipulating Text,nText Data Types Filed In Tsql

Jul 12, 2006

I have to run a dynamic sql that i save in the database as a TEXT data type(due to a large size of the sql.) from a .NET app.  Now i have to run this sql from the stored proc that returns the results back to .net app. I am running this dynamic sql with sp_executesql like this..
EXEC sp_executesql @Statement,N'@param1 varchar(3),@param2 varchar(1)',@param1,@param2,GO
As i can't declare text,ntext etc variables in T-Sql(stored proc), so i am using this method in pulling the text type field "Statement".
DECLARE @Statement varbinary(16)SELECT @Statement = TEXTPTR(Statement)FROM table1 READTEXT table1.statement @Statement 0 16566
So far so good, the issue is how to convert @Statment varbinary to nText to get it passed in sp_executesql.
Note:- i can't use Exec to run the dynamic sql becuase i need to pass the params from the .net app and Exec proc doesn't take param from the stored proc from where it is called.
I would appreciate if any body respond to this.

Manipulating Large Tables

Feb 15, 2008

I'm in the midst of a long file conversion job. Today I found that one of the tables (converted from csv) to be 6.7 million records. My sql script which I use to reconfigure the weird original date format, into something the rest of the planet uses, times out due to the size.

Does anyone please know of a file utility to automagically split sql server 2005 tables for later re-combining once my scripts have successfully completed their task on the smaller tables?

Very Large Recordset

Aug 10, 2007



I have a stored proc which returns a very large recordset (150,000 rows +). Each row has upto 65 - 95 fields. I need to do row transformations on each row.

I am using an Execute SQL Task to execute the stored procedure to return the results into a Object variable which I then shred inside a Source Script Component (by casting it into a recordset datatable and looping it and assinging into an Output columns).

Obviously the recordset variable is enormous - stuffed with 150K large rows. But what choices do I have in this scenario? Can I persist the recordset variable to disk? I cannot stream the result of a stored proc execution. So what I do about the sluggish performance of this enormous variable?

thanks in advance

Use Replace() In An Update In A Large Ntext

Apr 21, 2008

I've got a table that I have to update in preparation for our environment move (2k to 2005 SP2). The developers that designed the application created a table called schemas, which holds the contents of an XML file inside of an ntext field named Data.I need to parse through the field and do a find/replace to replace all instances of www.site.com with www7.site.com. It's all over the place in the file. The problem is, that the datalength() of each of the fields (there are 2 rows) are above 15000.normally, I'd run something like this:update schemas set data=replace (cast(Data as varchar(max)),'www.site.com','www7.site.com') where data like '%www.site.com%'Smaller columns it works great - but it won't work on these because they're too big (the update will chop anything beyond the varchar(max) value). I could do it manually, but this DB will be refreshed from production on a weekly basis and I'd like to script as many of the environment changes to the DB as much as possible. Any ideas?

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.

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 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)

Ntext Over 4000 Chars Causes 'Data In Row (n) Was Not Update... String Or Binary Data Would Be Truncated...'

When I enter over 4000 chars in any ntext field in my SQL Server 2005 database (directly in the database and through the application) I get an error saying that the data could not be updated because string or binary data would be truncated.Has anyone ever seen this?

Report Builder - Read Data From SQL Server With Ntext Data Type

I have a column in SQL server which is of type ntext. Selecting the specific column to view it in report builder, an error message appears with the following description:

- Cannot run this report. The grouping expression 'nameofcolumn' returns the datatype binary. The Grouping Expression cannot return binary data.

Report Builder recognises this as if it was an image...

Data Conversion From String To Decimal When Saving Data To SQL Server 2005 Using An ADO Recordset

Feb 12, 2008

Hello,

I am wondering what conversion rules apply, when a string, which contains a number, is saved to a SQL Server 2005 into a column of type decimal.

This is the code I€™m using (C++):

CString cValue = "0.75"
_variant_t vtFieldValue;
vtFieldValue = _variant_t(cValue)
pRecordSet->Fields->Item["MyColumn"]->Value = vtFieldValue;

"pRecordSet" is an ADO recordset. The database column "MyColumn" is of type "decimal(19,10)".

The most important question for me is, if the regional settings of the database server or the regional settings of the client PC are considered during the conversion from the string to the decimal value. For example in standard French regional settings the "." would not be recognized as decimal separator.

I am also wondering if the language of the database instance, in which this data is saved, is considered during this conversion or any other settings of this database instance.

So my general question is: Does anybody know exactly what rules apply during the above mentioned conversion?

Thank you for your help.

Regards,
Volker

Converting Text Data To Ntext Data

Mar 27, 2006

Hi all,

My organization have a web-based application and needs it to support multilingual so we will be adapting our app to use unicode. However, one of our problems is to convert existing data from text to ntext. I couldn't find anything that document this. What is the best way to do that? I would like to be able to migrate the data from an existing text column to another ntext column in the table.


I brief you about my system, I used List manager system to store the messages and distribute to all members. Right now,by design the Lyris system keep the message in the text field which mean it 's not support multilanguage directly because of unicode field. We needs to create new Db which has the data structure as same as Lyris but just one difference is keep the message in unicode format (ntext) which we need the sql script to automatically update the new record get from Lyris to new DB.


If I can't do that, what are the options? If it's possible, I would like to be able to do this in sql script.


Thanks a mil, in advance.

Sql Ntext Data Truncates In Asp

Feb 27, 2006

The sql database has an ntext (16) field which contains "information" and is used as a free form turnover log. When I bring this data into an ASP page the "information" gets truncated.

I have tried getchunk, however all formatting on the field is lost.
I have tried putting the field at the end of my query - no change.
I have tried querying the data as a separate sqlrs connection - no change.
I have tried using substring to break it down, the first substring works, however I get errors on the second (Expression result length exceeds the maximum. 8000 max, 12000 found).

I also tried to use substring in sql query anaylzer - and only get the first ~4180 characters.

Is there a way to split this field into multiple nvarchar fields in my temporary table in sql and then concatenate back together in asp report???

Get Length Of Data In An NText Column

Feb 27, 2004

I have some text in an NText column that could be quite long.

for the web page that displays it, i want to show the first 200 characters and then have a "more..." link to bring up the full text.

i'd like to create a stored procedure that takes the left 200 characters and copies them to a ShortText column (NVarChar) for initial display and then id like to set a bit column to indicate if the length of the NText column is greater than 200.

Len and Left cant be used against NText so how can i work with the NText data ??

NText Data Type Issue

Feb 15, 2002

Have a table storing nText data tied into a Cold Fusion front end. The Cold Fusion returns the values fine, but when querying in Query analyzer the messages are being truncated. In Enterprize Manager I get a <Long Text> message.

I ran OBJECTPROPERTY and found that TableTextInRowLimit was set to 0, but even after i set it to 1 on our test system with a value of 2000, it still truncated.

Also, the field is set to ntext with a length of 16. I havent worked much with nText, anyone with advise would be much appricated.

How To Put Data From A Recordset Into A Table

Jun 24, 2004

I want to transfer a recordset (derived from an Oracle datasource) into
an SQL2000 Server table using VBScript in a ActiveX Script Task using a DTS.

Currently I use the OPENROWSET (and OPENQUERY) method, however
the lenght of the querytext seems to be limited to 8192 bytes.
At this moment I have reached the limit of this lenght, and I am looking
for a solution.

Futher info: The query returns large recordsets of 100,000s of records with 100s of columns. Because of it's complex structure, the standard data transformation in SLQ2000 is not an option.

Using a substitute like:

varRecords = rst1.GetRows
For intI = 0 To UBound(varRecords, 2)
rst2.AddNew
For intJ = 0 To UBound(varRecords, 1)
rst2(intJ) = varRecords(intJ, intI)
Next
Next
rst2.Update

works fine but is much to slow.

Can anyone help me to find a solution?

Render Just The Raw Data From The Recordset

Feb 1, 2008


Is there a way to return just the raw data from a report? I do not mean XML rending which marries the dataset information with the layout information. I just want the raw data from the dataset. If the XML returned was the result of the recordset from the de-parameteraized query only that would be great!

I am looking into writing a Custom Rendering Extension, but I am not fining much outside of the same MS example circulating. It seems to only deal with layout data and not the raw dataset data.

Is there way to get to just the raw data and ignore layout? Is the dataset in the SSRS Temp Dd that you can query after a report has run? If anyone knows of any way to get to the raw data that would be fantastic.



Thanks!

I am running a Access97 front end with a SQL Server 7 backend. On records with an ntext datatype, you are only allowed to update records if the ntext field is null. The tables are linked from access. You get a "cannot update linked table" and "ODBC error #306." Any suggestions??

Ntext Data Type Cannot Be Selected As DISTINCT

Mar 3, 2008

Hello,
When I am using DISTINCT in the SELECT clause for a table having a column of datatype "ntext" in SQL 2000 as well SQL 2005, it fails giving the error as "ntext data type cannot be selected as DISTINCT". This is coz
"The text, ntext, or image data type cannot be selected as DISTINCT."

But I am able to insert into a temporary table having a column whose datatype is nvarchar) using this SELECT clause in SQL 2000. Please advice me how this happens. If I am not worng, implicit conversion has happened. But this insert fails raising the same error in SQL 2005. Please help me to find the difference
thanks in advance!

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

SqlCe Ntext Data Types And VS2005

Jun 28, 2007

I have an application where I'm trying to store xml data in a db field defined as ntext. I have a dataset and table adapter setup in VSNet 2005 and SqlCe 3.1. When I look at the table adapter in the VS designer it shows the field with a type of String and a size of 2147483647 which appears to be correct. Also, if I look at the code generated by the MSDataSetGenerator tool it shows the parameter defined in the same way as in the following
param = new System.Data.SqlServerCe.SqlCeParameter();
param.ParameterName = "@Questions";
param.Size = 2147483647;
param.IsNullable = true;
param.SourceColumn = "Questions";
this._commandCollection[2].Parameters.Add(param);

My problem is that when I run the application and try to insert an item into this column the application throws an exception related to corrupted memory. Trying to debug the problem I found at run time, the param.Size value for the ntext parameter had been set to 255. Since the specific xml I was trying to insert was 410 characters in length I'm guessing that this is what is causing the crash.

Is the expected behavior (the setting of the size to 255 that is)?
If not, am I missing some trick here?

Thanks
Neil

How Do I Parse Data Stored In Ntext Field

Apr 9, 2008

I have a third party application with a ntext field that I need to parse the data out of. The data looks like this:
<xmlF><FNumber type="int">2421</FNumber><AttachmentPath type="string" /><RequesterId type="int">232</RequesterId><Requester type="string">John Smith</Requester><RequestDate type="DateTime">3/24/2008 11:23:27 AM</RequestDate</xmlF>
The fieldname is Data and the tablename is ProcessData
Again, this looks like xml, but the field type is ntext. I would like to create a view displaying the parsed data in fields. How would I go about parsing the data?
Thanks.

Export NTEXT Data To Flat File

Feb 22, 2007

Hello,

I have not worked with NTEXT data before. I have a situation where I need to export a SQL Server 2000 table of data that has NTEXT columns in it. The plan is to archive the data to CD, and delete the data from the table once it has been archived.

I have tried exporting the data to a text file and specified a Ragged Right format in the Flat File connection manager. Do I need to somehow concatenate the data from the table in order to export it to this kind of file?

Thank you for your help!
