Conversion From Char To Nchar
Apr 16, 2004
Hello,
I am trying to convert a single code page MS Server database into a unicode database, using the unicode data types,NCHAR, NVARCHAR, NTEXT. The problem is that in the original database, indexes and constraints have been defined on the tables whose configurations need to be changed. As a result, the ALTER TABLE command fails. Are there any other alternative solutions?
Also, data from the old database needs to be preserved. The objective is to create a unicode database which keeps the old data intact as well as accepts the new data in unicode.
It would be great if you could help!
Thanks,
Sheetal.

can anybody please explain me why microsoft using nvarchar/nchar instead of varchar/char in northwind database and pubs database. I know if a column holds unicode data you should use nvarchar or nchar but for me all those tables in northwind/pubs are not holding unicode data. but still why microsoft settled for nchar/nvarchar.

Hi I have a table, which contains Char and NChar NOT NULL columns
Now I need to change it to NULL, when I use the following command, it fails for the following error,
The command I used,
ALTER TABLE <TableName>
ALTER COLUMN <ColName> CHAR NULL
ALTER TABLE <TableName>
ALTER COLUMN <ColName> NCHAR NULL
Msg 8152, Level 16, State 13, Line 1
String or binary data would be truncated.
The statement has been terminated.
But for the same table, the below command executes fine,
ALTER TABLE <TableName>
ALTER COLUMN <ColName> SMALLINT NULL
Also I can change the NULLABILITY from NOTNULL to NULL using Enterprise Manger, editing the table using Table Design and selecting Allow Nulls option.
I need a script to accomplish this task.
Any help would be greatly appreciated.

#1 This stored procedure can be used to search and replace substring in the char, nchar, varchar and nvarchar columns in all tables in the current database. You should pass the text value to search and the text value to replace. So, to replace all char, nchar, varchar and nvarchar columns which contain the substring 'John' with the substring 'Bill', you can use the following (in comparison with the SetTbColValues stored procedure, this stored procedure replace only substring, not the entire column's value):
EXEC replace_substring @search_value = 'John', @replace_value = 'Bill'

An OLE DB error has occurred. Error code: 0x80040E07. An OLE

Hi,
I'm scrambling to complete a project and ran into an int to char problem. I'm sure, in my haste, I'm doing something stupid. Here is an example of what I'm trying to do but it doesn't convert as expected. I want the SEQ_NBR2 value to convert from 4 to 0000004.
select right('0000000' + convert(char(7), isnull(a.SEQ_NBR2, 0.0)), 7)
fromTXN_HEAD_837 a
where a.file_auth_nbr = '1084472388468'
anda.seq_nbr2 = 4
and a.sgmt_id2 = 'BHT'
Thanks, Jeff

I have data tables that include ZIP code, as char(5). The values looklike integers, but they are padded with leading zeroes to fill out 5characters, '00234'.There are SPs to look up data, with @Zip char(5) among the parameters.Some users call these with integer values, @Zip = 234, and SQL makesthe conversion. Is it necesary to add the leading zeroes in the SP --@Zip=RIGHT('00000'+@Zip,5) -- or would SQL find this match? (234 ='00234'). It looks like the conversion is to '234' and the matchfails.Thanks,Jim GeissmanCountrywide

Hi
Is it possible to have SQL Server recognize the following character field as a date using convert or cast (or anything else):
2001-03-25-02.27.55.365252
so that I can do date comparisons such as
select * from table where [char in above format] < getdate()

I'm trying to run the following statement. If the first row of invoie data has a number the invoice for the rest of the rows that contain text come through as null. If the first row of data is text i'm fine. How do I convert the invoice to text as it is being read from the below statement?

here is my problem:
i have a variable @sid_x as binary(16) = 0x4CF254AB0BA5D411AA3E00508BC5C413
and i want to use it as argument in sp_addlogin statement.
select @sqlcmd = 'sp_addlogin "test", @sid = ' + @sid_t
/* this doesn't work, because @sid_t is binary... */
select @sqlcmd = 'sp_addlogin "test", @sid = ' + convert (char (20), @sid_x)
/* this doesn't work either, because it doesn't convert to binary text */
my question, is there any way i can get @sid_x in follow text format
0x4CF254AB0BA5D411AA3E00508BC5C413 ?

Hi guys/ladies I'm still having some trouble formatting a select statement correctly.
I am using a sqldatasource control on an aspx page. It is connecting via odbc string to an Informix database.
Here is my select statement cut down to the most basic elements.
SELECT commentFROM informix.ipr_stucomWHERE (comment > 70)
The column "comment" contains student grades ranging from 0-100 and the letters I, EE, P, F, etc. Therefore the column is of a char type. This is a problem because I cannot run the above statement without hitting an alpha record and getting the following error
"Character to numeric conversion error"
How can I write this statement where it will work in the datasource control and have it only look at numeric values and skip the alpha values?
I have tried case with cast and isnumeric... I don't think that I have the formating correct.
I have also used:
WHERE (NOT (comment = ' I' OR comment = ' EE' OR comment = ' NG' OR comment = ' WP' OR comment = ' WF' OR comment = ' P' OR comment = ' F'))
This works but is very clunky and could possibly break if other letters are input in the future. There has to be a better way.I am sorry for my ignorance and thanks again for your help.

After testing out the application i write on the local pc. I deploy it to the webserver to test it out. I get this error.
System.Data.SqlClient.SqlException: The conversion of a char data type to a
datetime data type resulted in an out-of-range datetime value.
Notes: all pages that have this error either has a repeater or datagrid which load data when page loading.
At first I thought the problem is with the date, but then I can see
that some other pages that has datagrid ( that has a date field) work
just fine.

I am using Visual Studio 2005 and SQL Express 2005. The database was converted from MS Access 2003 to SQL Express by using the upsize wizard.
I would like to store the current date & time in a column in a table. This column is a smalldatetime column called 'lastlogin'.
The code I'm using is:
Dim sqlcommand As New SqlCommand _
("UPDATE tableXYZ SET Loggedin = 'True', LastLogin = GetDate() WHERE employeeID = '" & intEmployeeID.ToString & "'", conn)
Try
conn.Open()
sqlcommand.ExecuteNonQuery()
conn.Close()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
This code works fine on my local machine and local SQL server. However at the client side this code results in the error as mentioned in the subject of this thread. I first used 'datetime.now' instead of 'getdate()', but that caused the same error. Then I changed the code to 'getdate()', but the error still remains.
The server at the client is running Windows Server 2000 UK . My local machiine is running WIndows XP Dutch.
Maybe the conversion from Dutch to UK has something to do with it. But this should be solved by using the 'Getdate()' function..... ?
