Hi,
I have a funny Error in our sql server 7 & 2000. When I compare two
string in Unicode format. I receive that it is the same when I add new
nchar.
I don’t understand why?
Could you help me ?
declare @str nvarchar(128), @str2 nvarchar(128)
Set @str =
nchar(21121)+nchar(49352)+nchar(47811)+nchar(48256 )+nchar(4966)+nchar(25
736)+nchar(1788)+nchar(51220)+nchar(17733)
Set @str2 =
nchar(21121)+nchar(49352)+nchar(47811)+nchar(48256 )+nchar(4966)+nchar(25
736)+nchar(1788)+nchar(51220)+nchar(17733)+nchar(4 1273)
select @str
select @str2
SELECT DIFFERENCE(@str, @str2)
if soundex(@str) = soundex(@str2)
BEGIN
SELECT 'OK'
END
ELSE
BEGIN
SELECT 'KO'
END
if @str = @str2
BEGIN
SELECT 'OK'
END
ELSE
BEGIN
SELECT 'KO'

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.
I created a package in IS. My source file is an excel file and my destination file is a sql server 2000 table. when i ran the package the following error was displayed:
"Cannot map a unicode format to a non-unicode format".
My sql table is non-unicode. I modified my text field to be unicode and it ran. I have many tables and do not wish to modify them manually. Is there a way around this problem??
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
Hi,See this code:DECLARE @SQL nvarchar(4000)SELECT @SQL = 'SELECT * FROM CUSTOMER WHERE CustomerName = N''TrầnTấn Háº*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.
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.

I have date coming to one page as a string in the following format"May 4 2005 12:00AM" I need to query one of my tables using this date in combination of other nondate values. How can I convert this date into valid sql server datetime format before I query a database tables Please help
I have a table which stores date-of-birth in varchar 19861231(yyyymmdd). A view takes this data. I want to store this date as mmddyyyy in the view. How can we achieve this?
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 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.
Hi I wanna put string in query "where" part.For example,$sql="select VEHICLEFROM databaseWHERE MECHANIC =BRIAN";like above, "mechanic" column is filled with strings. Then how can Iwrite "where" part?Above query does not work.Thanks.
Ok, here is what i'm trying to do and its driving me nuts.
ok,
1) I have a proc that runs and needs to validate the user prior to running - this proc is called from an hand held device
2) the id and password are being passed as "clear text" but the password is stored in the database table hashed.
Is there anything on the db side that can get the hash value from the password column of the aspnet_membership table and compare it to the password being passed in to this proc? I have suggested several options to the handheld developer but nothing. This has to be done on the database side.
so,
username and password are passed to proc from handheld.
proc needs to validate ther user in the aspnet_membership table
if user id and password are valid execute the stored procedure
is this possible? if so can ANYONE point me to some examples of this being done?
I have used a query statement with the following WHERE string to 'Fill' a dataset. "AND (A.ApptsDate > '" & strApptPreDate & "' OR (A.ApptsDate = '" & strApptPreDate & "' AND A.ApptsTime >= '" & strApptPreTime & "' ))" & _ and strApptPreTime is defined as:Dim strApptPreTime As String = SomaShared.strPadTime(CStr(dApptCalcNewDate.Hour) + ":" + CStr(dApptCalcNewDate.Minute))
Somehow, the dataset showed only the ApptsTime after 10 am. After more than 2 weeks of debugging, I still can see a dataset watch for > 10 amAppsTime only. Now I am guessting, the problem is 9 is different from 10 - 16, it all because 9 is single digit. Then I check the data type settings for these variables. Here are what I found: In SQL Server Agent job, the ApptsTime data was 'inserted' by @NewApptTimes, which is declared as char(5).In SQL Server database, the ApptsTime was defined as nvarchar(15). My question are: 1. The reason why there were no 9 am data for the dataset, is becasue 9 am of nvarchar(15) is not > 8:30 of strApptPreTime? 2. If the answer to the quation 1 is yes, how do I define AppsTime and/or strApptPreTime? TIA,Jeffrey
Hi All, I have a column in my table like so: 'D4B00 L2A00 L3A00 L6C00 P1C00 L2A28 P4B00 ' How do I check in SQL if any pieces have the first 3 character the same. In the above case, L2A is present twice. I need to do this because I need display disctinct items, therefore L2A needs to be displayed only once. Any help is appreciated. Thanks

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.
