Text Data Type From Deleted Table (trigger)
Feb 12, 2003Hi,
I need to prevent modification/update to a field.
So I created a trigger. To take the data from DELETED table then replace the field data.
However, I have problem with one field which data type is text.
MS SQL always return me this error:
Cannot use text, ntext, or image columns in the 'inserted' and 'deleted' tables.
I use the following code to take the data from deleted table
DECLARE @ptrval varbinary(16)
SELECT @ptrval = TEXTPTR(NOTES )
FROM DELETED
I also tried simple Select statement
Select notes from deleted
What code should I use to take the deleted data
Please help.
Thanks in advance
Update On Large Table - Change Data Type For Text Column
Dec 10, 2014I need to update a large table, about 55 million rows, without filling the transaction log, in the shortest time as possible. The goal is to alter the table and change the data type for Text column from VARCHAR(7900) to NVARCHAR(MAX).
Since I cannot do it with an ALTER TABLE statement (it would fill up the transaction log) I'm thinking to:
- rename column Text in Text_OLD
- add Text column of type NVARCHAR(MAX)
- copy values in batches from Text_OLD to Text
The table is defined like:
create table DATATEXT(
rID INTEGER NOT NULL,
sID INTEGER NOT NULL,
pID INTEGER NOT NULL,
cID INTEGER NOT NULL,
err TINYINT NOT NULL,
[Code] ....
I've thought about a stored procedure doing this but how to copy values in batch from Text_OLD to Text.
The code I would start with (doing just this part) is the following, but maybe there are more efficient ways to do it, or at least there's a better way to select @startSeq in the WHILE loop (avoiding to select a bunch of 100000 sequences and later selecting the max).
declare @startSeq timestamp
declare @lastSeq timestamp
select @lastSeq = MAX(sequence) from [DATATEXT] where [Text] is null
select @startSeq = MIN(Sequence) FROM [DATATEXT] where [Text]is null
BEGIN TRANSACTION T1
WHILE @startSeq < @lastSeq
[Code] ....

Oct 9, 2007I have a field that is currently stored as the data type nvarchar(10), and all of the data in this field is in the format mm/dd/yyyy or NULL. I want to convert this field to the smalldatetime data type. Is this possible?
I've tried to use cast in the following way, (rsbirthday is the field name, panelists is the table), but to no avail.
SELECT rsbirthday CAST(rsbirthday AS smalldatetime)
FROM panelists
the error returned is "incorrect syntax near 'rsbirthday'.
I'm rather new to all things SQL, so I only have the vaguest idea of what I'm actually doing.
Thanks for the help!

Mar 11, 2008
The ERP manufacturer used an image data type to store large text data fields. I am trying to move these data types from one database to another database using either Sql Queries or MS Access. I can cast them as an 8000 char varchar to read them directly but have no luck importing into these image data fields.
Access and Crystal are not able to read these fields directly.
Any suggestions? Most information about these fields has to do with loading files but I am just moving data.

DB Design :: Alter Partition Function In Data Vault Where There Is 4 Table Dependency?
Aug 28, 2015I'm currently stuck with a table that has 350 mil records. Querying this table is insanely slow so I had a better look at existing yearly partitioning. I already managed to partition on a month level which increased the performance/querrying a lot. I did this on the staging table where I used an alter statement to split the 2015 partition by 12 months.
However, in our project we used Data Vault. This means that we have 4 tables (hub, sathub, link, satlink), all carrying 350 mil records. The problem is that altering the partition function does not work. The server cannot handle this action. What the best way is to do this, without having to drop/reload all tables.

In the SQL Server documentation, it is said that, the text data type will contain upto 2GB size. I assumed it will save upto 2GB. But what happened is, it saves only 255 characters all others were truncated. Is there anything wrong with me? Or the wrong is with the SQL Server?

Mar 23, 2008I'm having a bit of a problem with this data type. It is supposed to be able to store about 2,147,483,647 characters, but when I enter more than about 1,834 characters no more charaters can be stored.
Has anyone experienced this and knows how to allow up to the 2,147,483,647 characters. Is it anything to do with another SQL Server setting or variable that needs to be changed
Thank you in advance for helping on this.

TEXT Data Type In SQL Server
Aug 20, 2004Sorry if this is a dumb question.
I have a SQL Server TEXT Data Type field which stores a long description.
However when I update it from C# (ASP.net) through a textbox, it seems to cut off a part of the data if the number of characters is a big size (+- more than 577 characters).
I pass the data from then textbox to a string, but as soon as I run the Create/Update stored procedure that gets passed the string field, it seems to chop off the string.
What am I doing wrong?
Should one rather use a SQL Server string field for descriptions (+-1000 characters long) or should one use the TEXT field for this purpose?
Which one's performance is better?
Text Data Type And Performance
Dec 13, 2005I was wondering if someone could clear this up for me...
I have a table that will be used to store information about products that I will be selling on a new website. I would like to store each product in a table which will include a description of around 1000 words. I was deliberating over whether to store this chunk of text in a column with the data type set as 'text', or to store the text in a seperate txt file on the server. The search facility on the site will not be required to query this text so which would offer the best in terms of performance?

May 22, 2006Hi,I have a problem on an old app. This application is a Help Desk, any Computer related problem (Motherboard Burn Out, Software Crash, dll) on my company will be recorded using this Help Desk application.One month ago, some programmer found a bug in this program lead to many duplicate data on database. But too late, This program has entered production stage and used for more than 2 years. This bug only happen at some condition so I found out after 2 years running (when my boss reported there are some duplicate data on "helpDesk" table).The bug is solved but helpDesk table need some "cleaning" operation. Here is structure of that table :helpDesk Table- id (primary key, integer auto increment)- reported_by (varchar 200)- problem_title (varchar 200)- problem_description (text)- date_summited (datetime)well usualy if I want to find some duplicate data I wil type :SELECT MAX(uid) AS uid, reported_by, problem_title, COUNT(uid) AS total_duplicateFROM problemsGROUP BY problem_title, problem_description,uidHAVING (COUNT(uid) > 1)But that query will not work because problem_description data type is "text" which not support "group by" statement.Any other Idea how to locate and cleaning up this duplicate data?thanks

Problem With Using A 'text' Data Type.
May 18, 2004I am using a 'text' data type in a table and am having trouble adding data to it. I'm using an MS Access ADP project front end for my forms. I want to copy and paste from a text editor such as NotePad to a 'text' data type field in a form. There appears to be a limit that the field will accept which is much below the 2GB size that is allowed for the field. I get the following error message: "The text is too long to be edited." Once I get this error I can add characters from the keyboard but eventually the field will not accept any more characters. Typing or pasting does nothing. I can delete. So I've hit a limit but I'm not sure if it is in Access or SQL Server.
Any help would be appreciated.

Text Data Type Problem
Oct 12, 2007I have a table named 'Documents' with a field named 'DocumentData' which is of the datatype Text.
I am using the following statements in a stored procedure which on execution gives errors:
DECLARE @DocData VARCHAR(100)
DECLARE @OrderID INT
IF ISNULL(@DocData, '') <> ''
BEGIN
IF EXISTS( SELECT DocumentData from Documents where OrderID=@OrderID and DocumentData = @DocData)
RaisError ('Document ignored.', 16, 1)
The errors that i am getting are the following :
Msg 279, Level 16, State 3, Procedure SPDocs_LoadData, Line 41
The text, ntext, and image data types are invalid in this subquery or aggregate expression.
Msg 306, Level 16, State 1, Procedure SPDocs_LoadData, Line 41
The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.
Can anyone tell me how to rectify this? Basically i am trying to find out whether @DocData passed in the stored procedure matches the value in the table.
Thanks.
