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 ??

is there any way or a tool to identify if in procedure the Parameter length was declarated less than table Column length ..
I have a table
CREATE TABLE TEST001 (KeyName Varchar(100) ) a procedure
CREATE PROCEDURE SpFindNames ( @KeyName VARCHAR(40) )
AS
BEGIN
SELECT KeyName FROM TEST001
WHERE KeyName = @KeyName
END
KeyName = @KeyName
Here table Column with 100 char length "KeyName" was compared with SP parameter "@KeyName" with length 40 char ..
IS there any way to find out all such usage on the ALL Procedures in the Database ?

For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.
The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "¶mname=value&parm2=value..." format.
The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:
Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)
The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.
THIS IS A PROBLEM!!!
Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!
Thanks for your help in advance,
LOSTlover

Hi,
I have an SSIS Package where I am looping through all input columns and creating an XML out of it. The Problem comes in one of the tables where I have an Ntext column. Instead of giving me the value of the column, it gives me
"Microsoft.SqlServer.Dts.Pipeline.BlobColumn"
I am trying to get the string value from this blob column. For that I am using the below code. Can you please point me to where I am going wrong. I am not very good in VB so I might be doing some casting error.
Dim blobCol As Microsoft.SqlServer.Dts.Pipeline.BlobColumn
Dim ByteVal As String
For Each column In Me.ComponentMetaData.InputCollection(0).InputColumnCollection
columnValue = rowType.GetProperty(column.Name)
Select Case column.DataType
Case (DataType.DT_NTEXT)
blobCol = DirectCast(columnValue.GetValue(Row, Nothing), Microsoft.SqlServer.Dts.Pipeline.BlobColumn)
ByteVal = System.Text.Encoding.Unicode.GetString(blobCol.GetBlobData(0, CInt(blobCol.Length)))
newXML += ((FormatElement(column.Name) + ReplaceSpecialChars(ByteVal) + FormatElement(column.Name, True)))
Case Else
newXML += ((FormatElement(column.Name) + ReplaceSpecialChars(columnValue.GetValue(Row, Nothing).ToString()) + FormatElement(column.Name, True)))
End Select
Next
Thanks in advance.
Regards

I'm trying to run the following SQL against my ntext column, Testtbl.Task I want to replace where the ampersand sign got HTML encoded to "&", and I want to strip it down to only the ampersand sign and deletethe "amp" and the ";".It executes, but I still have the HTML encoding for the ampersand sign if the issue is NOT the first character in the ntext column. If it's the first part of the ntext column, then it works.

Hi,
I am working on an application which accesses SQL database. I have a table complaint in which i have a coulmn 'history' of type "ntext". When i insert a value, the value gets stored in the db correctly, but I cannot access the complete data from that field using a simple select query. I had to export the table to a text file only then i could view the complete data of the field.
I wrote the query in query analyzer as:
"select history from complaint where pkey=142"
& the result i got is:
"
###### admin: Jan 8, 2007 3:53:57 PM GMT Type: Inactive (Key 10) Description: Activity yet to be started State: Planned "
This is only a part of the entire string that I had entered.
My requirement is that I need to access the data from the ntext field & save it in a variable & then display the entire data in my application. Can anyone tell me how should i use the select query so that i get the entire data without having to go thru the export data procedure.
Please help!!!

Hi,
I have a table column type as nText, however there are some Chinese character stored in that field and it is a messed up as it is not readable.
In my vb.net code, I did Convert to unicode by getting the byte of each character and encode it with UTF8 e.g:
Public Shared Function ConvertToUnicode(ByVal s As String) As String
' Convert To Unicode
Dim MyBytes As Byte() = Encoding.Default.GetBytes(s)
Dim GBencoding As Encoding = System.Text.UTF8Encoding.UTF8
Return GBencoding.GetString(MyBytes)
End Function
This works well but ,the problem is that it slows down the process quite alot, and I wonder are there any text encoding method I can use in SQL that can run when i do the SELECT Statement?
SELECT
Convert(MyNTEXTColumn)
....
something like that?
Thanks.
Jon

I am having some difficulty writing a relatively basic query. The objective is to retrieve the new stories (headlines) for the past 3 days from the database. Since each headline can be assigned multiple categories (topics) the query returns a row for every headline assignment. I can't use the 'Group By' expression because one of the columns is nText.
So basically if there is an article written yesterday, "I Love Cats" that gets assigned both topics 'CATS' and 'PETS' I only it returned with the first topic assigned... 'CATS'. Here is a little image of the three tables being called:
http://64.225.154.232/temp_dbDiagram.gif
I don't think that this query is too difficult, but I'm just getting my feet wet with writing queries that are more than select * from whatever. Any insight or recommendations are greatly appreciated.
SELECT headline.HEADLINE_ID, headline.HEADLINE_TITLE, headline.HEADLINE_DATE, headline.HEADLINE_THUMBNAIL,
topic.TOPIC_NAME, topic.TOPIC_URL
FROM tbl_CCF_Headlines headline INNER JOIN
tbl_CCF_Headlines_Topics ON headline.HEADLINE_ID = tbl_CCF_Headlines_Topics.HEADLINE_ID INNER JOIN
tbl_CCF_Topics topic ON tbl_CCF_Headlines_Topics.TOPIC_ID = topic.TOPIC_ID
WHERE (headline.HEADLINE_DATE IN
(SELECT TOP 3 HEADLINE_DATE
FROM tbl_CCF_HEADLINES
GROUP BY HEADLINE_DATE
ORDER BY HEADLINE_DATE DESC))
ORDER BY headline.HEADLINE_DATE DESC

Hi,
I have exported a report to excel that contains an ntext column. The exported excel file shows "#Error" for the ntext column in some of the rows. If I see the same report in reporting services I don't see any problem. I have checked that this is not any issue with the length of the text. Could you suggest me something on this?
Thanks

SQL syntax to split a column that contains ntext values that are separated with this value : ;#
I need it to create 3 new columns
i.e.: I have a column that contains values such as:
ROW1: ;#typea;#typeb;#typec;#typed;#
ROW2: ;#typeb;#typec;#
ROW3: ;#typeb;#
I need it to convert to 3 new columns and strip out the ;#:
E.g.:
Column 1
typea
typeb
typeb
Column 2
typeb

Hi,
I am creating a piece of code to create audit tables based on my current tables. I'm using the info in sysobjects to get this done, but I have one problem.
I can't seem to find the actual lenght of a column, I tried with the systypes.length, but that was obviously not what I needed. Does someone know how (or where) I can retrieve the length that I need?
thx in advance.

I have a table this is populated by a flat file. In the desc field from the flat file some of the data is very long up to 150 characters in length. I have to export this data after some transformations to a fixed width file. I need to check the length of the data in the desc field and any thing that is to long needs to be put in a desc2 field, however any values in desc that are shorter than 36 characters in length needs to have spaces padding it up to 36 characters as well as the desc2 field. Any help would be great. I am not the best T-SQL programmer in the world and have limited time to get this done.

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)

Howdy folks! (I feel im creating too many topics...but all my questions are unrelated :-/)
Dev environment: SSCE, Native c++ OLE code, Win CE 5
I have a routine that calculates the size of a set of columns in order to create a byte buffer for retrieving data from an IRowset and inserting it into a custom class. This method works great for all data types except ntext. When I look at the column information from an ntext field, the DBCOLUMNINFO::ulColumnSize member holds 536,870,911 (the max length of an ntext type). Obviously I dont want to allocate 1GB of memory for each ntext column. Is there anyway (natively) to determine the actual number of characters in a field?

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? I cannot figure out what is causing it, ntext should be able to hold a lot more data that this...

Hi all,
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...

Hello Friends,
I am working on a web application and using Sql Server 2005 as a Databasew. I want to define a variable with the datatype as defined in the database. Let me give an example.
In my web say there is a field "First Name" and for that I had created a TextBox "txtFirstName" in code behind to get this value I have defined a variable
String getFirstName;
Now this variable has to be stored into the table "Person" into the column "FirstName" which is of type "nvarchar" and having length "20" So I want to get this length programatically so that I can assign this number (20) to the maxlength property of the textbox "txtFirstName" so that in future if the legth of the database column changes it should no be needed to change in code also.
Caqn it be done? If yes please let me know.
Thanks & RegardsGirish Nehte

Hi!
I recently was confronted with a problem where a piece of text that was included in many NTEXT column values in a table needed to be replaced with another piece of text. You can't issue normal REPLACE statements against NTEXT columns, so this seemed to be a bit of a challenge €” issuing a REPLACE() against a TEXT or NTEXT column in SQL Server yields error
I tried following
UPDATE CaseTypeDefs SET definition = replace(LTRIM(RTRIM(definition)), '<![CDATA[sp_YOTAssetAdditionalOffences 0, ArgParamHearingsId, ArgParamLanguage, ArgParamReferralId]]>', '<![CDATA[sp_YOTAssetAdditionalOffences 0, ArgParamHearingsId, ArgParamLanguage]]>')
But this is producing following error
Server: Msg 8116, Level 16, State 1, Line 1Argument data type ntext is invalid for argument 1 of replace function.
For Example: I want to replace string <![CDATA[sp_YOTAssetAdditionalOffences 0, ArgParamHearingsId, ArgParamLanguage]]> with <![CDATA[sp_YOTAssetAdditionalOffences 0, ArgParamHearingsId, ArgParamLanguage, ArgParamReferralId]]> in NTEXT column values in a table.
Need help, how to do it?.
Thanks In Advance

Hello, I am using the JDCB-ODBC driver for my app, but one of the columns in my WHERE clause is 255 characters long. Because of this no rows are returned even though the statement should return 1 or 2 rows. I've tried other JDBC-ODBC drivers too and they have the same problem. Additionally, I've tried using RTrim(), Substring(), etc and it still will not work....any ideas? Is it a driver bug? Anyone know of a driver that will work?
Sample code....
ResultSet rs = dbRetrieve.getStatement().executeQuery( sql ) ;
if (rs.next()) {
// Never gets here
}
Thanx!

Hello,
I have an ODBC connection manager to a Progress database. In that database there is a column declared as a string of 10 characters long.
However, some data in this column is actually up to 15 characters long.
This makes my DataReader Source fail everytime I try to run my package because it sets the output column like this :
Datatype : Unicode string [DT_WSTR]
Length : 10
Is there any way to solve this without changing the datatype in the Progress database (that is beyond my control) ?
tanks in advance ...

Hi,
I have a table with 500 columns, most of them are type of varchar. I would have the following data set:
ColumnName DataTypeLength MaxLength
-------------------- -------------------- -------------------
ColA 50 42
ColB 10 7
ColC 50 8
.... ... ...
I can have a query to get the data type length (hom many varchar) for each columns:
SELECT column_name, data_Type, character_maximum_length
FROM information_Schema.columns
WHERE table_name='***'
ORDER BY ordinal_position
but I have problem to get the actual maximum length of the each column. Anybody have the similar query?
thanks,
