Escaping International (unicode) Characters In String
May 29, 2007
Y'all:
I am needing some way, in the SQL Server dialect of SQL, to escape unicode
code points that are embedded within an nvarchar string in a SQL script,
e.g. in Java I can do:
String str = "This is au1245 test.";
in Oracle's SQL dialect, it appears that I can accomplish the same thing:
INSERT INTO TEST_TABLE (TEST_COLUMN) VALUES ('This is a1245 test.");
I've googled and researched through the MSDN, and haven't discovered a
similar construct in SQL Server. I am already aware of the UNISTR()
function, and the NCHAR() function, but those aren't going to work well if
there are more than a few international characters embedded within a
string.
Does anyone have a better suggestion?
Thanks muchly!

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'm connecting to a SQL Server 2005 database using the latest (beta) sql server driver (Microsoft SQL Server 2005 JDBC Driver 1.1 CTP June 2006) from within Java (Rational Application Developer).
The table in SQL Server database has collation Latin1_General_CI_AS and one of the columns is a NVARCHAR with collation Indic_General_90_CI_AS. This should be a Unicode only collation. However when storing for instance the following String:
__ÙÚÜÛùúüû_ÅÆØåæøßÇçÑñ__ЎўЄє?ґ_пр?туф_ЂЉЊЋ ... it is saved with ? for all unicode characters as follows (when looking in the database): __ÙÚÜÛùúüû_ÅÆØåæøßÇçÑñ__??????_??????_????
The above is not correct, since all unicode characters should still be visible. When inserting the same string directly into the sql server database (without using Java) the result is ok.
Also when trying to retrieve the results again it complains about the following error within Java:
Codepage 0 is not supported by the Java environment.
Hopefully somebody has an answer for this problem. When I alter the collation of the NVARCHAR column to be Latin1_General_CI_AS as well, the data can be stored and retrieved however then of course the unicode specific characters are lost and results into ? So in that case the output is as described above (ie __ÙÚÜÛùúüû_ÅÆØåæøßÇçÑñ__??????_??????_????)
We would like to be able to persist and retrieve unicode characters in a SQL Server database using the correct JDBC Driver. We achieved this result already with an Oracle UTF8 database. But we need to be compliant with a SQL Server database as well. Please help.
i've worked with SQL Databases for years now, but never needed to deal with international characters. I am trying to search strings like surname in a column that might have international letters/characters, such as:
select * from [dbo].[User] where LastName like '%Hekimoğlu%'
It doesn't retrieves anything. I've googled for while in a hope to find some solution quickly, but to my surprise I couldn't. how to query string columns that include international characters such as above.I am using SQL Server 2012, Nvarchar(100) for column.
In SQL 2000 DTS, I was able to append data from an ODBC source to a SQL 2000 destination table. The destination table was created by copying an attached source table in Access to a new table, then upsizing it to SQL. The character fields come over as varchar, and that seemed to be fine with the DTS job.
Now using the same source table and the same SQL destination, only in SQL 2005 with Integration Services instead of DTS, I get an error because the connection manager interprets the source text fields as Unicode and the destination fields are varchar.
I could script the table and change the text fields in the destination table to nvarchar, but this could have adverse affect on the application that uses the destination table. Is there a way to make the connection manager see the source text fields as varchar, or have the integration package allow the append even though the destination is varchar and the source is nvarchar?
In my package , I am used CDC Source transformation and received the Net changes then insert into Destination. But whatever Data coming from CDC source data type Varchar value needs to Converting Non Unicode string to Unicode string SSIS. So used Data conversion transformation to achieved this. I need to achieve this without data conversion.
I am following the SSIS overview video- URL...I have a flat file that i want to import the contents onto a SQL database.I created a Dataflow task, source file and oledb destination.I am getting the folliwung error -"column "A" cannot convert between unicode and non-unicode string data types".in the origin file the data type is coming as string[DT_STR] and in the destination object it is coming as "Unicode string [DT_WSTR]"I used a data conversion object in between, dosent works very well
I've had some great headaches with SSIS this morning, which I have managed to get a workarounds for, but I'm not happy with them so I've come to ask for advice.
Basically, I am exporting data from an SQL Server database into an Excel spreadsheet and hitting issues with unicode and non-unicode data types.
For example, I have a column that is char(6) and have added a data conversion step to the data flow, which converts it to type DT_WSTR and then everything works!
However, this seems like a completely un-neccessary step as I should be able to do the conversion in T-SQL - but no matter what I try I keep getting the same problem.
SELECT Cast(employee_number As nvarchar(255)) As [employee_number] FROM employee WHERE forename = 'george'
ErrorValidation error. details: 1 [1123]: Column "employee_number" cannot convert between unicode and non-unicode string data types.
I know I have a solution (read: workaround) but I really don't want to do this everytime!
I have an Excel Source component hooked to an OLE DB Destination component in my SSIS 2005 Data Flow Task. After I mapped the excel columns to the OLE DB table columns i get these errors below. I noticed that for the first error, the Excel Field format (when you mouse over the column name in the mappings section in OLE DB component) is of type [DTWSTR] and the corresponding SQL field from my SQL table that it's mapping to is of type [DT_STR] when mousing over that field in the mappings in the properties of my OLE DB component. All table fields in SQL Server for the table I'm inserting into are of type varchar.

I use Visual Studio's, integration project to load XML file into SQL Server. In the XML file, i have defined collumns as string. When i try to load XML file with parts defined in scheme as string, i get an error "cannot convert between unicode and non-unicode string data type.
Destinated collumns in SQL are defined as varchar and char.
I have spent countless number of hours trying to solve the issue, but to no vail. My problem is SSIS throws "cannot convert between unicode and non-unicode string data types" when i am try to transform data from DB2 to SQL Server 2005. And please note, i tried all possibilities like changing the destination field which is in SQL Server 2005 to nvarchar and also text. But so far no help. And i also looked at previous posts which did not help me either.
Hi, Data in the table appearing with strange characters [probably unicode]. For instance obeserve the string [marked in red color] "Rod. Anhang?era s/n§". When I export the same to excel and apply language as portuguese it shows properly. The actual portuguese languguage has ascents in the sentence. This where the problem is seen.
I wanted to display them back in normal form could please suggest me the best possible way to cast such characters.
I have a table with nVarchar column.If i do a search like this ----------------------------------------------------------------------SELECT ID, Book, Chapter, Number, Amharic, EnglishFROM tbl_testWHERE (Amharic LIKE '%??ቅር%')----------------------------------------------------------------------it doesn't return anything but if i add 'N' after LIKE as ----------------------------------------------------------------------SELECT ID, Book, Chapter, Number, Amharic, EnglishFROM tbl_testWHERE (Amharic LIKE N'%??ቅር%')----------------------------------------------------------------------It returns the whole table without filtering.Can someone help me with this?
I got a weird problem here, i hope your valuable suggestions will help me in solving it... we extract data from AS400 servers to our Extract Database(SQL Server) using SSIS. The data coming from china has a weird problem, Couple of columns come in chinese language, though we have set the respective columns as nvarchar(50) we see on our extract database that they are not chinese charecters but something really bad data symbols as:
(9(
+¦
2¬ o|a&]
2¬ o|a&]
+N|( <
....
....
etc....
I hope you are understanding what i mean ...may be i need to do something(probably change some properties) in the SSIS packages which extract data from the AS400 Servers.
Has anyone encountered such a problem...I will look forward for your valuable suggestions.
Hi,Our school has an application in which :- Teachers enter comments through a web interface built in asp (notasp.net).- Comments are stored in a SQL server 2000 (in a nText field)- Comments are printed through a MS-Access 2002 front-end...Most comments are in English, Spanish or French. Some comments areEnglish + Japanese.- The Japanese teachers can enter their comments through the webinterface without any glitch.- The comments are obviously stored properly in the nText field, asthey can be displayed through the web interface.Here is where problems start to occur...- When browsing through the table using the Enterprise Manager, thecomment appears blank if it contains some Japanese.- When browsing through the table in Access (the table being linked),we can see the series of unicodes :漢字テス... while, in the next paragraph, theEnglish text is perfectly readable...- Similarly, on the printed report, the Japanese text appears as aseries of Unicodes, while the English text appears perfactly readable.If I copy the Japanese text from the web interface and paste it intothe linked table in Access, it displays perfectly and prints perfectlyin Access. But of course, I can't do that manually for all students...However, if I now look at the same record through the EnterpriseManager, I see the text (at last !) but only as a series of unreadablecharacters. I can imagine that that last problem is due to a lack ofJapanese font in the Enterprise Manager, bacause if I copy theseuneradable characters and paste them in the original web form, theydisplay perfectly...I would really appreciate if someone could help me sort out thatproblem.Many thanks for all ideas.DL

I create my database table with a text field of nvarchar(), added some japanese kanji characters and so on. Everything works great, I can insert kanji and retrieve kanji and display them just fine from my c# application, however if I try to search for kanji using a WHERE = '' or a WHERE like '' clause, it doesn't score a match. Not even a direct one.
I'm on XP using a japanese locale with IME installed. The kanji shows up in Enterprise Manager correctly, it even shows in the query for the table, yet the WHERE clause won't record a hit. Changing the collation on the field to "Japanese" or "Japanese UNICODE" doesn't seem to have any effect.
I am having an issue fetching Chinese characters in a XML data type. It return questions mark (?).
Below is the sample script.
DECLARE @XMLVAR XML SET @XMLVAR = '<?xml version="1.0"?> <POLICY_SEARCH xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <NAME>QA*保险1</NAME><NUMBER /></POLICY_SEARCH>'

Hi,usually, I'm not using MS servers, but I have a big problem with aAccess table.I should create a web application for a Historical Dipartment.They have create a populated a Access database using unicodecompression field (for ancient language).I would like to export this table into MySQL o Postgres, but it'simpossible because when I export this table in a .txt o cvs format theunicode charaters have been "destroyed" for memory allocation problems(cause Access use a compression tool for unicode fields).Also with professional tools for dump Access to another DBMS.I would to know if using a MS SQL server I can skip this problem causeboth MSQLserver both Access are Microsoft product.Thank you ;)J
I'm new to SSIS, using Terdata Attunity connector for integrating data flow between Terdata (source) to SQL Server (Target).
SSIS package is getting failed because of length mismatch between source and Target for Unicode character datatype columns. Reason is Teradata TPT always occupies 3 times more length of actual defined in DB.
Even I tried by increasing length of attribute in Source but it didn't work.
I know by converting datatype from unicode -> Latin would work, but i don't want to do conversion since loosing some characters.

TPTAPI_INFRA: API306: Error: Conflicting data length for column(5) - Source column's data length is (200) Target column's data length is (300). ##################################################
Hi,We have stored proc name proc_test(str nvarchar(30)). So far this prochas been invoked from a .NET application assuming that only Englishcharacter strings will be passed to it. The calls are likeproc_test('XYZ')We now have a requirement for passing Chinese strings as well. Ratherthan changing the calls throughout the application, we would like tohandle it in the stored procedure so that it treats the string as aunicode string. Can we apply some function to the parameter to convertit to unicode so that we don't have to call with an N prefixed to thestring?Thanks,Yash
My requirement is that if the string in the column has any of the characters from 'ACDIPFJZ' , those characters have to be retained and the rest of the characters have to be removed.
Hi,See this code:DECLARE @SQL nvarchar(4000)SELECT @SQL = 'SELECT * FROM CUSTOMER WHERE CustomerName = N''TrầnTấn H*n'''PRINT @SQLThe result always is this:SELECT * FROM CUSTOMER WHERE CustomerName = N'Tr?n T?n H?n'
I am getting an issue when i try to run a package which was validated against an oracle database on windows with UTF8. When I try to run the same package(no changes, just changing the conenction parameters to point to an oracle database on UNIX with UTF16), the package fails with error saying cannot convert unicode to string for string columns. The same run through fine if I refresh the metadata against the UNIX database, but then it doesnt run against the Windows database.
Can anyone please suggest how to overcome this scenario. My issue is, I need to run my package against various database(by just pointing the database connection details) without changing anything in the package.
Hi, I want to convert literal string to unicode before insert into the database. and after insertion i want to retrive this value from data base and convert back to literal string. pls tell me how to incode and decode literal string to unicode and from unicode to literal string.

I am using OLE DB source to extract data from Oracle. I have query (sample) like below, but SSIS is converting ID as Unicode String [DT_WSTR]. Why is that? and how to avoid this?
I'm using a Unicode sql script imported using OSQL. One of the valueswe are attempting to insert is a Registry Multi-String value by passinga string to a stored procedure. These Multi-String values appear to bedelimited by a Hex 06 (^F) character. When I import this character,embedded in a string preceeded by an N, i.eN'somethingsomething2something3'I end up with TWO of this character in the db. I get :somethingsomething2something3Any help figuring out why or how to fix this? We MUST use Unicode dueto extended character sets, so NOT using Unicode is NOT a solution.
