Downside By Chosing Ntext As Datatype For All Text Columns?

Are there any disadvantages to always using nvarchar(MAX)?
Is there a general downside by chosing 'ntext' as column type instead of a type that contains chars but with a limited max size like 'char' or 'varchar'?
I'm not sure whether a limited column size is applyable to all my colums. Therefore I would use 'ntext' for all columns containing text. Might this lead to problems in the future?
(I'm using Linq-To-SQL in a ASP.net Webforms application)
i have the below query where MessageText column is of ntext datatype..whe n i run the below query it is giving me the below error. Error :The data types ntext and varchar are incompatible in the add operator.
select li.LookUpPageInfoId, li.PageMessageID, li.PathMessageID, li.IsActive, m.MessageID, (select messagetext from messages where messageid=pagemessageid and channelid=m.ChannelID)+'/'+ m.MessageText as TotalText, m.ChannelID from LookUpPageInfo as li left outer join Messages as m on m.MessageID=li.PathMessageID and li.IsActive=1
Can some one suggest me how to concatenate the ntext column....but the above works good if the column MessageText is of nvarchar(max) datatype.

I just got URL Routing working on my web site but to do so I had to set runAllManagedModulesForAllRequests to true. Looking around real quick I did not see a triger just for an URL Routing Module for .Net 4 (just a complicated way to do it for 3.5SP1). What is the downside to leaving runAllManagedModulesForAllRequests (my server only has 2GB of ram and runs IIS 7 and SQL 2008 web so not much resorcess as is)? Also is there a module just for URL Routing that I can enable for all requests instead?

Now i want to get the list of message IDs where the message Text Contains some Special characters as like the characters from the below image. how to query to get the list of message ids where the message text contains any one of this special characters.
Scenario: If you create a table with a column of type nvarchar, populate it with some content and try to modify it using the WebMatrix editor, from nvarchar to ntext, it does not display any error message or warning that this is not possible. It silently saves and reverts the change, back to nvarchar. Wasted some hours on this issue as I thought my column was ntext, but in fact was still nvarchar.
Expected behavior: It should change to ntext, or if SQL CE doesn't support that, it should notify the user that no change was applied.
A variety of files (pdf, images, etc.) are stored in a ntext field on a MS SQL Server. I am not sure what type is in this field, other than it shows question marks and undefined characters, I am assuming they are binary type.
The script is supposed to iterate through the rows and extract and save these files to a temp directory. "filename" and "contenttype" are given, and "data" is whatever is in the ntext field.
[code].....
This works, but the file should be saving to the server instead of popping up save-as dialog. I am not sure if there is a way to save the response to file.
I am trying to explode some data from an ntext field into a cvs for import, here is what i have so far,
DECLARE @XML as XML DECLARE @hDoc as INT SET @XML = (SELECT billaddress FROM order WHERE id=7 ) exec sp_xml_prepairedocument @hDoc OUTPUT, @XML SELECT firstname FROM OPENXML (@hDoc, '//') WITH (type text './type/@text', FirstName text './FirstName/@text') exec sp_xml_removedocument @hDoc OUTPUT
here is the errors:
Msg 2812, Level 16, State 62, Line 4
Could not find stored procedure 'sp_xml_prepairedocument'.
Msg 8179, Level 16, State 5, Line 6
Could not find prepared statement with handle 0.
Msg 6607, Level 16, State 3, Procedure sp_xml_removedocument, Line 1
sp_xml_removedocument: The value supplied for parameter number 1 is invalid.
So I have a ntext column in a table with a combination of large random data (hence why ntext in the first place) and sometimes contains a uniqueidentifier.
I need to find and delete rows based on the uniqueidentifier.
I can't do the comparison with it being ntext, but I changed it to varchar(max) in my dev enviornment and it let me do it without any warnings and I can now do my comparison like I want to, so all is good.
I just want to make sure I'm not changing any of my large random data by changing the data type.
I have addded some different languages into database table column(NText), then im retrieving the data and display it on the Dropdownlist and Gridview but some of the languages(like Korea, Japan) displays as boxes.
I'm trying to compare a parameter of type String with a database field of type ntext. Below is my vb code. carDescription is a field in the database table that is of type ntext. The code didn't work because you can't use the equality operator.
Dim carDescriptionLookupCmdString As String = "SELECT carMake FROM car WHERE carDescription = @description" Dim carDescriptionLookupCmd As New SqlCommand(carDescriptionLookupCmdString, dbConnection) carDescriptionLookupCmd.Parameters.AddWithValue("@description", description) Dim reader As SqlDataReader = carDescriptionLookupCmd.ExecuteReader()
I am trying to concatenate two columns (text and date) in a dropdownlist. In sql query: SelectCommand="SELECT [name] + ' , ' + [date] AS abc FROM [table] ">It gives this error: The data types nvarchar(max) and date are incompatible in the add operator.
I need to create a complex report and export it to Excel.
In the first column header, text is displayed as "Hide Daily Columns", but I need the text to change as "Unhide Daily columns" when I click on it and when the text changes the columns under "daily" header (I have 3 columns under this header) present in the report shud be hidden and only weekly columns shud be visible. I am new to SSRS and tried out many ways but didn't get it.
I've found a lot of similar topics but none of them solves my problem.
I have table structure like that
[Code]....
Everyone suggests to change ntext type to nvarchar(MAX) and life will be beautyfull. But... First, I need ntext, simply because there should be text in this field.
nvarchar(MAX) equals 4096 bytes which is to small for large text. Second, I already have table with ntext field, which does not cause this error.
URL....According to my requirement based on columns value button text is changing. But I want to apply some action on it. Means previously, I used Command Name for a button and in Row Command event I have written the code which was working. But now, after writing this code I am getting an error message. Because now the button is converted into template field.
In my website, there is a page called "SMS Log"It contains a GridView, in which there are 5 columns:
1) SMS sent time 2) SMS Text 3) Recipients 4) status 5) Button (view detail) since, "SMS Text" is large and "Recipients" are more than 1.
So Gridview looks very conjusted, also it does not look good.Is there any other control I can use other than Gridview to show above 5 columns in a well organized way.
I am having with the a full text index I am developing for a product catalog. It does all work to a degree I am just seeing some strange things happening.
From the database side I have a Products table that is being indexed on both the PartNumber and Description columns because I would like the users to be able to search either or using the search function.
Problem 1:
whenever I use multiple words in the search I don't always get the results I am looking for, this happens most notably when I am attempting to say put in a full part number (which for in this case would look like "I 10-9.2")
Problem 2:
I am not 100% sure that this is the most efficient way of completing what I am attempting to accomplish here since I have 2 columns that I need to perform the search on
Here is an excerpt from the click even when the user clicks the search button on the page:
[Code]....
And here is the search functions called from the click event to firstly check if there are any results and the second to display the results in a custom gridview:
If i use the multi delimited than error shows.How to use the multi delimited.If i run the code to to load the text file given in above show the bellow error
Input array is longer than the number of columns in this table.
I know about the benefits that full text indexing provides when indexing columns that contain LOB such as varbinary(max), varchar(max) etc. But is there an overhead involved when using full-text indexing and full text search on columns that contain a small amount of data, such as varchar(50)?
