Doube Byte Characters
Jan 17, 2001I want to store some double byte characters in a table. Originally I planed to change all data type of fields which will store double bytes from VARCHAR() to NVARCHAR(). But i just found out we have no problem to pull and store foreign content(double byte characters) in fields with VARCHAR type( the content is showing correct after stored in database)
my question is : if VARCHAR can handle double byte character, what's the point of using NVARCHAR to store unicode character? any advice is appreciated.

Searching A String With Asian Characters (double Byte)
Jun 14, 2007My problem is that i can't search a field that contains Asian characters (Korean in this case).
The table user_Access_tab have 2 keys:
access_id nVarchar(50)
user_id nVarchar(50)
The sql query below is sent through a oledbcommand to a sql server 2005 database.
"select access_id, access_right from user_Access_tab where user_id ='HQ001kimjo012007-05-07 ì˜¤ì „ 11:50:323401'"
It doesn't show any hits even thogh i know there is a number of matching records.
The question doesn't generate an answer in SQL server manager studio eigher.
If i change the datatype on user_id to Varchar(50) the id is presented (in the database) as:
HQ001kimjo012007-05-07 ?? 11:50:323401
Then the question works, but why doesn't it work with nVarChar(50)?

Trying To Map To Tinyint - Single Byte Unsigned Int Not Working
Mar 11, 2008I have an Excel spreadsheet that I eventually land into my staging table. In between, I'm attempting to get a date code from the Date table. I'm using a Lookup Transformation Editor and mapping the fiscal week of year and fiscal year name. I know the fiscal year name is fine. When I have both the fiscal year name and the fiscal week of year, the package fails on the lookup step. In a data conversion, I convert the fiscal week of year to a single byte unsigned integer. (In the Date table, the fiscal week of year is a tinyint.) I'm not sure what I'm doing wrong?

Search String Field (nvarchar) For Unicode Characters
Nov 8, 2006MS 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.
SQL Server 2008 :: Identifying ASCII Characters In NVARCHAR Columns
May 25, 2010I have an issue where I am storing various international characters in nvarchar columns, but need to branch the data at one point of processing so that ASCII characters are run through an additional cleansing process and all non-ASCII characters are set aside.
Is there a way to identify which nvarchar values are within the ASCII range and can be converted to varchar without corruption? Also, the strings may contain a mix of english and international character sets, so the entire string must be checked and not just the first character.
i.e.
Pass:
'Hello', 'abc123'
Fail:
'太平市', 'abc太123'

Using A Varchar Versus A Nvarchar Causes Hungarian Characters To Be Displayed Incorrectly On The Webpage.
Jul 10, 2006I have a hungarian character which looks like a lower case o with two single quotes on top of it --> Å‘
I have this character stored in two table the datatype of the column where this is stored at is varchar in one table and nvarchar in the other. When I try to view the field in enterprise manager the character appears as it should in the 2 tables, but when I use a jsp page deployed on weblogic to look at this character the one stored in the column of type varchar displays perfectly, but the table in which the column is nvarchar the character on the jsp page appears as a Q instead.
Any inputs on how to correct this issue will be much appreciated. Any changes to the character set on the html / jsp pages has no affect on the result.
Thanks,

View 1 Replies View RelatedProblem Saving/retrieving Unicode Characters NVARCHAR With Unicode Collation (java Jdbc)
Aug 8, 2006I'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.
T-SQL (SS2K8) :: Replace Multiple Characters With Single Character In A Column?
Jun 21, 2012I am trying to replace all special characters in a column with one special character.
Example:
Table: dbo.Employee
Column: Name
Name
-------
edwardneuman!"<]
mikemoreno)'>$:
JeffJensen"?>"
I am trying to get the namepart to the left of ANY special character. To achieve this, I am thinking of replacing all the special characters with a single special character so that I can find the first occurrence of that special character and grab left of the special character (SUBSTRING/CHARINDEX). This way I don't need to loop through all the special characters.
I am expecting the following results:
Name
-------
edwardneuman<<<<
mikemoreno<<<<<
JeffJensen<<<<
SQL Server 2012 :: Replacing Recurring Characters In A String With Single Character
Jan 20, 2014I have a problem where I want to write a function to remove recurring characters from a string and replace them with a single same character.
For instance I have the string '12333345566689' and the result should be '12345689'. In Oracle I could do this with "regexp_replace('12333345566689', '(.)1+', '1')", but in T-SQL the only solution I could think of is something like this:
DECLARE @code NVARCHAR(255)
SET @code = '12333345566689';
SET @code = REPLACE(REPLACE(REPLACE(@Code, '1', '~1'), '1~', ''), '~1', '1');
and repeat this for 2 - 9. But I'm sure there is a more elegant version for this in SQL Server 2012.

Compare Nvarchar(10) With Nvarchar(1000)
Sep 4, 2007I had this question for quite a long time.
It seems the latter one don't take any extra storage space than the previous one.
As long as the real string length is less than 10.
Is that mean the latter one not cost anything?
I once heard the different is when they are in memory. But not sure of it.
Can anyone explain it and provide some official reference on it?
Thank.

Byte[] Value In SQL Query...
Feb 3, 2008 Hi people,I have a little problem with this!There are some variables in C# code: int personID = 10;
string personName = "Tom";
System.IO.BinaryReader reader = new System.IO.BinaryReader(FileUploadPersonPhoto.PostedFile.InputStream);
byte[] personPhoto = reader.ReadBytes(FileUploadPersonPhoto.PostedFile.ContentLength); After that, there is a SQL query: string query = "INSERT INTO PersonTable (PersonID, PersonName, PersonPhoto) VALUES ("
+ personID + ", '" + personName + "', " + personPhoto + ")"; In Debug mode, value of the query is "INSERT INTO PersonTable (PersonID, PersonName, PersonPhoto) VALUES (10, 'Tom', System.Byte[])" and it does not work! Is there any prefix or something else that I should put and make it work?Thank you in advance!P.S. Do not want to use sql parameters at this piont!
SQL Binary To C# Byte[]
Apr 6, 2004I have a binary column with length 20 in SQL server table. I store dynamically C# byte[] value range from 0 to 19. So for example, If I store length of 16 and when I try to retrive it back into byte [] in C# it returns whole length 20. When I see in debug it has value from 0 to 15 which I want to use but from 16 to 19 is zero. How can I get just length value which I stored.
I use DataRow to get whole row and from the row object I extract byte [] based on column name.
Thank you in advance....
CLR UDT Max Byte Size
Aug 24, 2007Hello,
I need some help working with CLR UDTs. I have created two UDTs called trajectory and point. Each trajectory consists of a list of points. Each point consists of three members : lon( type double), lat( type double) and datetime.
I have written my own IBinarySerialize.Write method for the trajectory type which is the following:
Dim maxSize As Integer = 4000
Dim value As String = ""
Dim paddedvalue As String
Dim i As Integer
Dim pt As Point
For i = 0 To point_list.Count - 1
pt = point_list.Item(i)
If i = 0 Then
value = value & pt.X & "|" & pt.Y & "|" & pt.D
Else
value = value & ">" & pt.X & "|" & pt.Y & "|" & pt.D
End If
Next
paddedvalue = value.PadRight(maxSize, ControlChars.NullChar)
For i = 0 To paddedvalue.Length - 1 Step 1
w.Write(paddedvalue(i))
Next
If I try to store 225 points for a trajectory then the following error occurs:
System.Data.SqlTypes.SqlTypeException: The buffer is insufficient. Read or write operation failed.
Why is that happening? The limit size for a UDT is 8000bytes. Each point needs 24Bytes (2*SizeOf(double) + sizeOf(Datetime)).
Please help

DATEADD With 8 Byte Int?
Dec 18, 2006I have a bigint column called "MillisecondsSince1970" that I need to convert to a date - SSIS is erroring out when I use DATEADD with the 8 byte int (if I use 4 byte it works but the column is bigger than 4 byte). The error is really lame:
[Derived Column [79]] Error: The "component "Derived Column" (79)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "Date" (100)" specifies failure on error. An error occurred on the specified object of the specified component.

WHILE (4) Command prompt isql does not have the problem for the same UPDATE SQL and stored procedure.
Do you have any idea?
Create Certificate From Byte[]
Feb 4, 2008Hi,
Just wondering if anyone knows if you can create a certificate from a byte[]. For example, you can create an assembly using CREATE ASSEMBLY FROM 0x...; specifying the hex representation of it - can you do the same with a certificate? This means that you don't need to save the file to disk before loading it into the database.
Cheers,
Adam
Separate Lowercase Characters From Uppercase Characters

Hi everybody,
I would like to know if there is any property in sql2000 database to separate lowercase characters from uppercase characters. I mean not to take the values €˜child€™ and €˜Child€™ as to be the same. We are transferring our ingres database into sqlserver. In ingres we have these values but we consider them as different values. Can we have it in sqlserver too?

Code:
SHA512 sha = new SHA512Managed();
byte[] ReturnedPasswordByte = sha.ComputeHash(ToCryptByte);
MyGenericCommand.Parameters.Add("@Password", ReturnedPasswordByte);
MyConnection.Open();
MyGenericCommand.ExecuteNonQuery();
MyConnection.Close();
If I select the record later, all I get is "System.Byte[]" (as string)
