Problem Saving/retrieving Unicode Characters NVARCHAR With Unicode Collation (java Jdbc)
Aug 8, 2006
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.
Thanks in advance for your help.

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.

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.

Hi,
We want our database to be unicode complaint and i need a generic collation that should do the work irrespective of the fact what data is entered in the database. Can someone suggest me any generic collation for that.

I have a table that has arabic, japanese, utf8 and ascii strings in it. When I try and rerieve those strings using the windows odbc driver, the ascii and since byte utf8 characters come back fine, the arabic and japanese are returning as single byte characters. I read on microsofts page that odbc versions before 3.7 are considered non-unicode. When I look at the version of the odbc administrator it says 3.5. Is there a newer version of the sqlserver odbc driver or windows odbc administrator that I would need?
Is there some way to specify what the client charset is? I'm using SQLGetData with a target type of SQL_C_WCHAR.
Right now I have xp SP2 that has mdac 2.8 SP1.
Thanks for your help.

I have an SSIS package that pulls data from a MYSQL DB (Using RSSBus for Salesforce in SSIS to accomplish this). Most of the columns are loading properly, but I have many columns that I need to convert.
I have been using the Data Conversion dataflow task in SSIS to convert the rows.
I have 2 data conversions that work on most of the columns, but the DESCRIPTION column continues to return an error saying "Cannot convert between unicode and non-unicode types", regardless of what I choose on the Data Conversion task. So, basically I want to dump this column data into a SQL table with NVARCHAR datatypes. Here is what I am doing in my SSIS package...
1) Grab subset of data from SOURCE
2) Converts to TEXTSTREAM. (Data Conversion)
3) Converts to STRING. (Data Conversion)
4) Load Destination table. (OLE DB Destination)
I have also tried to simply convert the values to STRING, but that doesn't work either.
So, I have 2 Data Conversions working here that process most of the data correctly. What I can do to load the DESCRIPTION column?

Hi guys and gals,
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!
Any suggestions for what else to try?

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.

For packages that I have created to read Oracle 10g tables, that work fine with debugging in 32-bit mode, I get an error message on all string fields when I try to run in 64-bit mode. An example error message is:[OLE DB Source [1]] Error: Column "ACCT_UNIT" cannot convert between unicode and non-unicode string data types.Another interesting warning included is:[OLE DB Source [1]] Warning: The external columns for component "OLE DB Source" (1) are out of synchronization with the data source columns. The external column "ACCT_UNIT" needs to be updated.I cannot even try to convert this data with a Data Conversion item because the (red) error is on the OLE DB Source item and stops there. It doesn't matter what the destination is or even if there is a destination in the package yet.I'm using Oracle Provider for OLE DB, Oracle Client version 10.203 for 32-bit and Oracle Client 10.204 for 64-bit.Oracle is 10g on a UNIX 64-bit server and the data is not unicode.I'm using SQL Server Enterprise 2008 (10.0.1600) on Windows Server 2008 Standard SP1 on a 64-bit server.The packages work fine in 32-bit mode and the data is not unicode data. When I change Run64BitRuntime to True in the Debugging Property Page, I get the error on the OLE DB Source item. I also get the error when I schedule a package to run using the SQL Server Agent.

Hi,
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.
Thank You in advance.

Hi,
Hello everybody ...
I have a little problem with sqlserver.
When I call my procedure by asp, I send my parameters.
The parameters are nvarchar and arrive as parameter... like
@sentence which is '??t???'.
But I dont know how to apply unicode with parameter @
I explain:
Is it possible to do something like that ... obviously not:
IF @CountryNr = 14
SET @Sentence = N&@Sentence
OU
SET @Sentence = N+@Sentence

When I tried to insert armenian by doing the following
insert into tablex (field1) values (N'testdata')
it does not display in query analyzer or in the database as armenian.
When I copy this to word it does not convert it.
What else am I supposed to do to get that information to redisplay the correct way and I would appreciate any tutorials or samples you can show or direct me to.

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.
Thanks in advance for looking into this issue.
Thanks,
Niranjan.

hi all,
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.
thanks,

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.
Is there something I am missing here?

Y'all:I am needing some way, in the SQL Server dialect of SQL, to escape unicodecode 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 asimilar construct in SQL Server. I am already aware of the UNISTR()function, and the NCHAR() function, but those aren't going to work well ifthere are more than a few international characters embedded within astring.Does anyone have a better suggestion?Thanks muchly!GRB-----------------------------------------------------------------------Greg R.

Hi all, we are now planning to upgrade our application from anon-unicode version to a unicode version. The application's backend isa SQL Server 2000 SP3.The concern is, existing business data are stored using collation"Chinese_PRC_CI_AS", i.e. Simplified Chinese. So I thought we need toextract these data out to the new SQL Server which is using Unicode (Iassume it means converting them to nchar, nvarchar type of fields for Idon't enough information from the application side, or is there ageneral unicode collation that will make even char and varchar types tostore data as Unicode?).The problem is what's the best and most efficient way to do this dataconversion?bcp? DTS? or others?thanks a lot

I have built a large package and due to database changes (varchar to nvarchar) I need to do a data conversion of all the flat file columns I am bringing in, to a unicode data type. The way I know how to do this is via the data conversion component/task. My question is, I am looking for an easy way to "Do All Columns" and "Map all Columns" without doing every column by hand in both spots.
I need to change all the columns, can I do this in mass? More importantly once I convert all these and connect it to my data source it fails to map converted fields by name. Is there a way when using the data conversion task to still get it to map by name when connecting it to the OLE destination?
I know I can use the wizard to create the base package, but I have already built all the other components, renamed and set the data type and size on all the columns (over 300) and so I don't want to have to re-do all that work. What is the best solution?
In general I would be happy if I could get the post data conversion to map automatically to the source. But because its DataConversion.CustomerID it will not map to CustomerID field on destination. Any suggestions on the best way to do this would save me hours of work...
Thanks.

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.
##################################################
Error is
[Teradata Source [263]] Error: TPT Export error encountered during Initiate phase. TPTAPI_INFRA: API306: Error: Conflicting data length for column(5) - Source column's data length is (200) Target column's data length is (300).
