SSIS: Unicode And Non-unicode String Data Types
May 14, 2008
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.

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.

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?

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?

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'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_ÅÆØåæøߣÇçÑñ_¼½¾_ЎўЄєÒ?Ò‘_прÑ?туф_ЂЉЊЋ
... it is saved with ? for all unicode characters as follows (when looking in the database):
‚¬_£_ÙÚÜÛùúüû_ÅÆØåæøߣÇçÑñ_¼½¾_??????_??????_????
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_ÅÆØåæøߣÇçÑñ_¼½¾_??????_??????_????)
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.

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.

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.

Hi,
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.
Please suggest.
Thanks,
Manish

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.

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.

My ssis package exports .xls file data into a sql server table.
The fields in the sql server table have to be nvarchar instead of varchar.
If I use varchar then the ssis package gives an error about converting unicode to non-unicode...
Another ssis package exports .csv data into the sqme sql server table as above.
This time the sql server table fields have to be of type varchar because otherwise the ssis package gives an error about converting non-uniciode to unicode...
I basically would like to have a sql server table with varchar fields and let these packages import into it.
These packages may retrieve data from .csv or .xls.

I keep getting the error message below when attempting to import a text file (flat file) to an SQL Server Destination using SSIS. This database has recently been migrated from SQL Server 2000 (where I used a DTS Package that worked fine). I plan on doing further manipulation to the file after importing but have so far tried to keep one step at a time. I have tried using a smaller files and different tables but still get a similar response. I believe that the encoding of the text file is ANSI. If it is relevant the database collation is Latin1_General_CI_AS (the same as it was when 2000). Any help anyone can provide will be greatly appreciated!!!

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.

I'm trying to transfer some data from one table to another, in sql 2000 using SSIS. The tables are identical but have different owners. I'm getting "column __ cannot convert between unicode and non-unicode string data types". I am familiar with this when the data types don't match - however this is not the case. They are both nvarchar(50). The red x's show up on the ole db source and destination even when they are not connected. I added a conversion task and it changed nothing.
thanks for the help.

All:
When creating a package, SSIS assumes varchar columns as Unicode (DT_WSTR) so before loading data into the target tables, I have to perform a data conversion from DT_WSTR to DT_STR.
Is there any way to turn UNICODE off? So I do not need to do the conversion? Please advise...

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

Hello,
I have a ssis package that I created in the BIDS and run through a job.
the package was running very good all the time, till yesterday, when I changed the
default language of my server to hebrew (its an hebrew website).
now I get this error:
Code SnippetError: 0xC002F325 at CopyTables1, Transfer SQL Server Objects Task: Execution failed with the following error: "ERROR : errorCode=-1071636471 description=SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Unicode conversion failed".
helpFile=dtsmsg.rll helpContext=0 idofInterfaceWithError={8BDFE893-E9D8-4D23-9739-DA807BCDC2AC}".
Task failed: CopyTables1
how can I fix this error witout changing the language of the server?
Thanks.

Due to some legacy requirements, I'm using an OLEDB connection with the Jet driver and creating dBASE III tables (.DBFs) as the destination for a data export. The source is SQL Server 2000. The SQL table has a bunch of varchar columns, and I can't send them directly to the .DBF because SSIS complains that it can't (implicitly) convert from non-Unicode to Unicode. UNICODE?! dBASE III is ancient. Why would Jet/SSIS assume that these .DBFs are Unicode? As it stands, I have to put a data conversion task between the source and destination and convert all the columns. It's a real pain.
And no, I don't want to make all my SQL Server columns nvarchar. Is there any setting I can put in the connection manager or the connection string to prevent this error? I've already set AlwaysUseDefaultCodePage to True on the OLEDB destination component and the default code page is 1252. That didn't work; I still got the can't convert error.
