Convert A Unicode Database Into A Non-unicode Database
Jul 20, 2005
Hi there.
We have an application that can run on a non-unicode or a unicode sql
server
database.
Currently the application is running in a unicode database, as a
non-unicode database is less than half the size, I would prefer to
have a non-unicode database for demo purposes to be on my laptop, etc
etc
Is it possible to change a unicode sql server 2000 database into a
non-unicode database?
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 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?
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.
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 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.
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...
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!!!

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'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.
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 currently have a web application connected to a MSSQL 2005 database. We are signing some new clients to our web application who will be using a different language set. So were going have to change the database to Unicode? Anyone have any experience with this, or what are the steps implications involved?
I have a problem with Insert and Update Unicode data to database I can send Unicode data using string with N prefix (Ref 001)
Below I write some line of my SP But It does not write Unicode data to table, it writes like ???????? How to insert data using n prefix with Declared Variable? How can avoid this problem? Any other method to pass unicode data using SP? Please help me...
column UnitName nvarchar
Sample Stored Procedure (SP) SP header:
CREATE PROCEDURE ltrsp_AddEditUnit @UnitID char(4), @UnitName nvarchar(20), @UtrID int
Insert:
INSERT INTO ltrtb_Unit (UnitID,UnitName,UtrID) VALUES (@UnitID,@UnitName,@UtrID)
Update: --- UPDATE ltrtb_Unit SET UnitName=@UnitName, UtrID=@UtrID
WHERE UnitID=@UnitID
Ref 001:
found a method to insert unicode data to table (Using N' prefix), but I want to add using declared variable
INSERT INTO ltrtb_UserLevel (UserLevel,Description) VALUES (1,N'Unicode String') From the URL, http://databases.aspfaq.com/general/why-do-some-sql-strings-have-an-n-prefix.html
But I need to know how to pass the data using stored procedure
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

We have recently been looking into creating our SQL Server 2005 database as a unicode database using UTF-8 encoding. However initial search's suggest that SQL Server 2005 does not support the creation of UTF-8 db's and only supports UCS-2. Is this the case? If so then why is it not supported as most other vendors (Oracle, IBM) support it. If it is possible to create a UTF-8 database could you provide some details on how to go about this?
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 all,I am using a Strongly Typed DataSet (ASP.NET 2.0) to insert new data into a SQL Server 2000 database, types of some fields in db are nvarchar. All thing work fine except I can not insert unicode data(Vietnamese language) into db.I can't find where to put prefix N. Please help me!!!
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.
SQL Native Client 2005.90.3042.00 ODBC driver does not return SQL_CVT_DOUBLE as part of the mask from SQLGetInfo for SQL_CONVERT_WCHAR, SQL_CONVERT_WVARCHAR even though driver actually supports converting nchar and nvarchar to SQL_DOUBLE. For example,
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?
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.

The data file is a simple Unicode file with lines of text. BCPapparently doesn't guarantee this ordering, and neither does theimport tool. I want to be able to load the data either sequentially oradd line numbering to large Unicode file (1 million lines). I don'twant to deal with another programming language if possible and Iwonder if there's a trick in SQL Server to get this accomplished.Thanks for any help.Mark Leary----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==----http://www.newsfeeds.com The #1 Newsgroup Service in the World! >100,000 Newsgroups---= East/West-Coast Server Farms - Total Privacy via Encryption =---
