Not Allowing Updates Row With Ntext Data Types

Sep 19, 2000

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??

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

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.

Firing A Trigger When A User Updates Data But Not When A Stored Procedure Updates Data

Dec 19, 2007

I have a project that consists of a SQL db with an Access front end as the user interface. Here is the structure of the table on which this question is based:




Code Block

create table #IncomeAndExpenseData (
recordID nvarchar(5)NOT NULL,
itemID int NOT NULL,
itemvalue decimal(18, 2) NULL,
monthitemvalue decimal(18, 2) NULL
)
The itemvalue field is where the user enters his/her numbers via Access. There is an IncomeAndExpenseCodes table as well which holds item information, including the itemID and entry unit of measure. Some itemIDs have an entry unit of measure of $/mo, while others are entered in terms of $/yr, others in %/yr.

For itemvalues of itemIDs with entry units of measure that are not $/mo a stored procedure performs calculations which converts them into numbers that has a unit of measure of $/mo and updates IncomeAndExpenseData putting these numbers in the monthitemvalue field. This stored procedure is written to only calculate values for monthitemvalue fields which are null in order to avoid recalculating every single row in the table.

If the user edits the itemvalue field there is a trigger on IncomeAndExpenseData which sets the monthitemvalue to null so the stored procedure recalculates the monthitemvalue for the changed rows. However, it appears this trigger is also setting monthitemvalue to null after the stored procedure updates the IncomeAndExpenseData table with the recalculated monthitemvalues, thus wiping out the answers.

How do I write a trigger that sets the monthitemvalue to null only when the user edits the itemvalue field, not when the stored procedure puts the recalculated monthitemvalue into the IncomeAndExpenseData table?

One Or More Columns Do Not Have Supported Data Types, Or Their Data Types Do Not Match.

Oct 20, 2007



Hi,

I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:

at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.

So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:

The following columns cannot be mapped:
[Department, DEP_CLEGALCODE]
One or more columns do not have supported data types, or their data types do not match.

The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.

The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination

thanks.

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)

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.

Reporting Services :: Table Data Types For Data Driven Subscriptions

Jun 11, 2015

I am trying to find a reference for a client that lists the fields available to be substituted into a data driven subscription from the query, along with the expected data types.  For example, the field on whether or not to include a link to the report seems to be expecting a bit data type.I have searched and can't seem to find anything.  I guess I could walk through the interface and try different data types, but if  a list exists, that would be better.

Data Access :: Validation For Length Of The Character Data Types

Jun 10, 2015

I Have a table with #Sample like below

=================================
#Sample
id int,
SSN varchar(20),
State varchar(2)
 
Sample Data:

ID SSN STATE
1 999-000-000 AB
2 979-000-000 BC
3 995-000-000 CD
=================================

We used filter logic based on the SSN & State.

We are passing these values through variables like

Declare @State varchar(2)
Declare @SSN varchar(20)

While run time these values are lets suppose @SSN = '999-000-000' & @State='ABC'

Now the Result is displayed with the state data Like 'AB' only.

Output: 1 999-000-000 AB

instead it should give system generated error.

Here I have 2 Questions:
1. Why it is taking 1st 2 Charecters?
2. Why it does not have any system generated for length?

I can do validation with Length function for these 2 variables however if have 100 variables then it should not feasible case. So, what is the reason behind?

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

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

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!

Data Replication - Pushing Data Updates

Oct 26, 2007

Guys,

I have 14 databases, the last database - 14th one will have lookup tables only. The other 13 databases will have these lookup tables and data tables. At the end of each day I will make updates for lookup tables on 14th database, I want to be able to push the updates to any or some of the 13 databases. Look up tables will have only upto 100 rows, so I am not concerned about the bandwidth. What is the best way to accomplish this.

Any suggestions and inputs would help

Thanks

Dummy Where Clause Allowing Dummy Select Of Data - Utilizing Where Value = 1

Aug 30, 2007

Years ago, I remember while doing maintenance on a stored procedure seeing a 'Select x, y, z Where 'some value' = 1.

The function of this, I believe was to make the select work but not retrieve any actual values.


I am attempting to use this in an 'Insert Into Select values From' statement. This insert uses multiple selects via unions and I need a final dummy Select statement with no Where criteria.

What I am thinking may not even apply to what I need to do here.

If you recognize something even remotely near what I am trying to get across I would appreciate your sending me the code.

Another solution for me is just inserting one row with a final RecId = 6 and ' ' or 0 values for the other fields into a table
but I was hoping this would work.

Example:

Insert Into table
Select
1 as RecId,
' ' as field1,
field2
From test1
Where field2 = 'CA'

Union
Select
2 as RecId,
' ' as field1,
field2
From test1
Where field2 = 'NJ'

Union

/*Final Select */

Select
6 as RecId,
' ' as field1,
field2
From test1
Where 'some value' = 1'

Thanks much for your assistance!!!

Modifying Data Column Names And Data Types

Mar 13, 2008

I'm in the process of converting a rather huge VSAM database into a set of SQL tables.
I am using the same data names from the mainframe (like XDB-NAME to RDB-NAME).
I load the files using Import Export Data and it makes the tables with such column names as col001, col002, col003, etc... and always sets the data types to varchr(255).
And I have to cut and paste the data names from the manframe side to the server side (and the data types to.) 
So, is there an easier way to do this? Or am I doomed to cut-n-paste my days away...
Thanks for any help.
