Using A Varchar Versus A Nvarchar Causes Hungarian Characters To Be Displayed Incorrectly On The Webpage.
Jul 10, 2006
I have a hungarian character which looks like a lower case o with two single quotes on top of it --> ő
I have this character stored in two table the datatype of the column where this is stored at is varchar in one table and nvarchar in the other. When I try to view the field in enterprise manager the character appears as it should in the 2 tables, but when I use a jsp page deployed on weblogic to look at this character the one stored in the column of type varchar displays perfectly, but the table in which the column is nvarchar the character on the jsp page appears as a Q instead.
Any inputs on how to correct this issue will be much appreciated. Any changes to the character set on the html / jsp pages has no affect on the result.
I have table with a field defined as nvarchar. I want to change it to varchar. I have a stored procedure which defines the parameter @strCall_desc as nvarchar(4000). Are there going to be ay problems with running this sp if I just change the field type as described.
among our server-agent jobs is one for the log-reader-agent and its run status is displayed as error though the log-reader is working correctly, replication is working fine. it had hit an error some days ago after an unexpected shutdown - but it has been auto-restarted correctly on restart of the sql-server agent. now - what can i do to get back to a sensible run-status report? i have already deleted the job-history with the hope that this might help - but it didn't. should i just stop and restart the job again? can i somehow delete the status in the jobhistory? i would gladly appreciate any ideas because it's making me just mad to have a 'failed' job status on the monitor *g*
my question concerns both desktop and device apps.
I'm using sql compact to store some data. I often have to store strings (descriptions, url, etc.) but I don't know when to use nvarchar or ntext.
Nvarchar needs to have a size limit, but I often set it to 8092 when I don't know the actual limit (urls can be very long !). I fear Ntext because I suppose there is performances impact.
Is there any "rules" to help to choose which data type I'd use ?
Like in the subject: What are the cons and pros of using nvarchar(max) versus ntext? Does it have something to do with having to enable full text search perhaps in the latter case?
Greetings,I have a SQL server 2000 running on an english win2000 workstation. In adatabase I have a table where one varchar column is set to polishcollation.Regional settings for the system is polish.Data entered in a client application looks fine until they are posted.When reading the data with the client application, the special polishcharacters are incorrect, they appears as e.g. '1' and '3'.The strange thing is that when I use query analyzer to look at the data,then the polish characters appears as they should!My client app use ADO, the SQLOLEDB provider. I have tried to use'Locale Identifier=xxxx' in the connection string, without any luck.If I change the column to be nvarchar instead of varchar, then it work,but unfortunately, this solution is not an option. This should work onvarchar columns, since polish is not multibyte.What am I doing wrong??TIABest regardsPhilip Kofoed
For some reason a stored procedure which I have created is incorrectlysaving the date to the table. It seems the day and month are beingswapped around e.g. a date which should be the 12th April (12/04/2005)is saving as the 4th December (04/12/2005).The parameter used in the stored procedure comes from a VB6 app, Iamended this so the format was "yyyymmdd hh:mm:ss". The full line in VBbeing,Parameters.Append .CreateParameter("date_of_call", adChar, , 17,Format(firstCallDateTime, "yyyymmdd hh:mm:ss"))When I run my VB app it works fine, the syntax in the stored procedureis,CREATE PROCEDURE dbo.spUpdValues@data_id int,@date_of_call datetimeasupdate dataSET date_of_call = CONVERT(char, @date_of_call, 101)where data_id=@data_idIs it because the convert format is using an american date format ? Ican't see why as I can't reproduce this error using my own PC as thedate saves correctly, I can also confirm it's not happening to everybodywho uses the app. If it is happening for specifc users then what couldbe the cause. I've checked Regional Settings and all seems fine there.Any ideas on what could be doing this as I'm struggling to investigateany further.To debug I ran the stored procedure direct, manually inputting thevariable - again no problem. Also, the following SQL statment shows noproblem...declare @date_of_call datetimeset @date_of_call = '20041101 08:30:00'select CONVERT(char, @date_of_call, 101)select CONVERT(char, @date_of_call, 106)------------------------------11/01/2004(1 row(s) affected)------------------------------01 Nov 2004(1 row(s) affected)Any help would be much appreciated.*** Sent via Developersdex http://www.developersdex.com ***
i have used nvarchar as my datatype in sql server 2000 now i have decided to change to varchar as i can increase the character length from 4000 to 8000 Do I Lose data if i change the datatype.
I have a table using nvarchar(for what ever reason which beyond me why its a nvarchar...) that I would like to change to a varchar. There is no unicode in the fields so I don't have to worry about but I don't want to lose any text data. Will coverting the data type lose data?
I am converting this table to something that will be multi language compliant. My question is, I know that NVARCHAR's take double the space of a VARCHAR. Do I actually need to double the length of the VAL field to store the same amount of data or does the DB handle that?
Basically I want to store a 128 character NVARCHAR.. do I need to set my table up like this:
I am currently cleaning up my database to get its total size down and am not sure how nvarchar and varchar work exactly.
When defining the length of a varchar or nvarchar in enterprise manager, will that effect the size of the entry (as far as data size) no matter what the length of the entry? In other words, will there be a difference in Data Size for an entry with the length of 4 characters with a definition of varchar(4) versus an entry with the length of 4 characters with a definition of varchar(50).
****If there is no difference, is there any reason in trying to best guess the size to give nvarchar or varchar columns? It would seem easier to just define the lengths of columns which need variable lengths to 200 or 400 just to save time in not trying to best guess what the size might be...*****
Can someone please explain to me how the datapages in Microsoft SQL Server 2000 works. The pages are supposed to be 8K, that is 8192 bytes of which only 8060 are accessible for data storage (due to overhead). Now, I currently have a table containing 8 fields. Two of these fields are varchar and should be converted to nvarchar. One of the varchar fields is limited to 255 characters and the other to 4000 characters. When I convert the 255 characters field to nvarchar it works just fine, but when I want to convert the 4000 characters field I get an error from MS SQL saying that it gets to big. Is the error only for the 4000 characters field (which growths to 8000 bytes when using nvarchar instead of varchar) or must the whole table fit into one datapage? Could a blob maybe solve my problem, or will I face new problems when storing unicode characters in a blob?
I have a table with a Varchar field that will contain encrypted data. Since each byte can have a value from 0 through 255, can I use Varchar or should I change the field to NVarchar? The reason I ask is that during testing, the Varchar field sometimes is truncated, supposed to be 16 bytes but ends up as 5 or 6 or something less than 16.
Hi,I have a pretty straightforward question to do with variable length fields I hope someone can help me with:When using varchar (or nvarchar), is there any point in specifying a smaller length than the maximum? Does it save space or improve performance at all?ThanksRedit: I suppose the max rowsize is an issue. any others?
HiThe maximum length of a nvarchar could be 4000 characters while that ofvarchar could be 8000.We are trying to use unicode which would require that the datatype forone our fields be converted from varchar to nvarchar. But looks likethis would result in loss of existing data.Is there a way to do this without loss of data?Many thanks.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
Please I know this is fustrating but I really need help with this issue:
I am getting data conversion error when I tried to load data from one SQl table to another SQL table using SSIS.
The source table has a column with data type nvarchar(max). Also the destination table has the same data type nvarchar(max) but I keep getting conversion error when I use SCD transformation.
Error: " Input column "des" (116) has a long object data type of DT_TEXT, DT_NTEXT or DT_IMAGE which is not supported"
I am fine when I use OLEDB destination but I want to do an incremental load.
MS SQL 2000. Does anyone know how to find all rows where an nvarchar column contains a specific unicode character? Is it possible without creating a user defined function? Here's the issue. I have a table Expression (ExpID, ExpText) with values like 'x < 100' and 'y ≤ 200'. where the second example contains Unicode character 8804 [that is, nchar(8804)]. Because it's unicode, I don't seem to be able to search for it with LIKE or PATINDEX. These fail: SELECT * FROM Expression WHERE ExpText LIKE '%≤%' -- no recordsSELECT * FROM Expression WHERE PATINDEX('%≤%', ExpText) -- no records However, SELECT PATINDEX('%≤%', 'y ≤ 200') will return 3. Any suggestions? Thanks in advance.
I have looked at several explinations and I understand the difference between unicode and non-unicode. I get that the basic idea around storage is "double", 2 bytes instead of 1. My question is, does the 2 byte instead of 1 byte rule apply even if I am storing a char that doesn't need the full to bytes. for arguments sake I have a table called "UnicodeTable" and one column called "Letter". If I store the letter "A" on the first row of the "UnicodeTable" does the size of my database increase by 2 bytes?
I have an existing application that relies on a SQL Server database.
I want to switch all varchar fields to nvarchar so it can handle multiple languages.
The database has ~25 tables, many of which have varchar fields. I want to convert them all to nvarchar.
The database has ~150 stored procedures, many of which have varchar fields. I want to convert them all to nvarchar.
Are there any tools out there that would let me convert the tables of my choosing, and the stored procedures of my choosing, so that any 'varchar' mentions are changed to 'nvarchar' ? I've only used SQL Query Analyzer to write queries and use MS Access (and some SQL Enterprise Manager) to make the tables and relationships.
We have few stored procedures that use nvarchar datatype, this was not issue on SQL server 7.0 but in 2000 becomes a big issue. For example query that runs for 3 minutes in SQL server 2000 by replacing NVARCHAR to VARCHAR the same query runs for 2 seconds. The biggest challenge that I have deals with tables and user-defined datatypes of NVARCHAR that has been bounded to the table. How can I alter those without data corruption?
Hi, I'm starting a new application in java using JTDS jdbc driver(http://jtds.sourceforge.net) and SQLServer 2005 Express.I have to design the database from scratch and my doubt is if I have to usevarchar or nvarchar fields to store string data.Any experience about performance issues using nvarchar instead of varchar(considering that Java internally works in unicode too)?Thanks in advance,Davide.
There is a view in a SQL Server database that I need to connect to. If I connect to the database via Management Studio, the column CLIENT_NUMBER is nvarchar(15). Now in SSIS, if I add an OLE DB Source, access using a SQL Command, click Build Query, and add the view, I can see CLIENT_NUMBER as nvarchar(15) there too. Now I click OK, go to Columns, and I see that in both External Column and Output Column, CLIENT_NUMBER is specified as a DT_STR of length 30! The same thing happens if I use Table or view mode, and it happens with every nvarchar column here.
The kicker here is that I know this was working before. When I opened this package for the first time in weeks, I could see the Output Column as DT_WSTR length 15, so I know things were working then. In the meantime, I had installed SP2. Has anyone else heard about an issue like this? It certainly isn't happening with every package. Should I just take the ugly way out and CAST all of these nvarchar columns as nvarchars?
