Vchar Vs Char
Jul 20, 2005HiI have a SQL database with approx., 90m rows. Within the tablethere several fields that are varchar 4. On a test server with approx.200k rows I converted those to char4.It showed that the database size shrunk by approx. 20 %, why I don'tunderstand.My question is would I get a performance improvement for selectqueries against those fields when they are char4 as opposed to varchar4 ?Thanks

Apr 16, 2004Hello,
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.

Datatypes Nchar/nvarchar Vs Char/varchar
Dec 2, 2005can 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.

Changing Char/NChar Column From NOTNULL To NULL
Apr 19, 2008Hi 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.

This Stored Procedure Can Be Used To Search And Replace Substring In The Char, Nchar,
Jan 9, 2006#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'
Nvchar Fields Do Not Replicate
Apr 11, 2006Hi
This is my first post !
I have a database running on SQL server. It's setup as a publication and replicated to a subscriber by a pull subscription.
All my records seem to replicate accross - all new additions and deletions work fine as do most updates.
The problem is I have two fields - both declared as nvchar that do not replicate - they do not update when the published database changes.
Has anyone got any ideas what may be causing this.

VCHAR To XML After Table Is Load Via SSIS
Oct 26, 2007
I loaded a vchar column using script trans (SSIS doesn't support XML data types :/) to format the XML data properly. Since the XML data in the vchar column was not encoded, when I try to alter the vchar column to xml after the table is loaded it fails. I assume this is because the parser is having trouble with the content of the data within the xml tags.
This is how I coded the XML rather than using a xml method. "true" places the element end tag.
newXML += FormatElement("CONFERENCE") _
+ FormatElement("NAME") + ConvertToESC(RTrim(Mid(Row.activity, 1, 34))) _
+ FormatElement("NAME", True) _
+ FormatElement("START_DATE") + ConvertToESC(RTrim(Mid(Row.activity, 35, 8))) _
+ FormatElement("START_DATE", True) _
+ FormatElement("END_DATE") + ConvertToESC(RTrim(Mid(Row.activity, 43, 8))) _
+ FormatElement("END_DATE", True) _
+ FormatElement("CONFERENCE", True)
My question is, can I either load the data, using T-SQL, into an XML data type from a vchar column or is there a way to alter the type from vchar to xml without encountering the following parsing error?
Msg 9421, Level 16, State 1, Line 1
XML parsing: line 1, character 64, illegal name character
Thanks for any suggestions!

Get LangId By Nchar(1)
Apr 14, 2006Is it
possible in SQL 2005 to determine to which language symbol nchar(1) is
referred?
If
languages differ greatly, say, like Russian and English, can one write a function,
which, under the given alphabet, can determine to what language the symbol
belongs?
If the
languages have a similar alphabet, one is faced with the difficulties. For
example, it is needed to distinguish characters of American English from those
of Australian English or of English from those of any other European language
that uses almost the same alphabet. I don€™t know how to solve this problem.
What can you advise?
The final task
is to scan in Internet a great number of Web pages in various languages and to
make up a large dictionary, where each word will be entered in its language
group. It is in principle too important to select words in different languages
that use the same alphabet. Initial data for word selection will enter the
server in NTEXT format.

Nchar To Decimal..which Transformation
May 24, 2007Hi,
I selected the columns which i need in the data source itself and i need 3 columns,one will direclty go to the destination without any change/transformation and about the other two i need to do few lookups.
When i try to do lookup for One column which has the datatype in the source as nchar(3) though the date in the column is a number(like 150,160,170 and so on), my lookup table(a dimension in DW) where i want to get the actual key by looking up with this number doesnt allow me to map to the dimension in the DW, as the Dimension has this column datatype as decimal (3,0)....i tried the datatype conversion to convert the nchar to decimal but it doesnt transform i dont know why...probably i am doing some mistake...Could someone suggest how to deal with this and which transformation to use..?
I'd really appreciate if someone on this forum suggest how to deal with this..?
thanks

Differences In Results Of Nchar() And Unicode() Fu
Apr 3, 2008Hi,
I am working on an application that uses accent characters.
SELECT nchar(256) returns A. But if I do
SELECT Unicode(A) , then it returns 65 i.e. the value for simple 'A' character. I am confused, because I have data in nvarchar fields,
but when I do string comparison then A and A are treated as equal.
Please let me know, what could be the issue.
Thanks
Unicode Is Nvarchar, Ntext, Nchar
Apr 10, 2008When I tried to insert armenian by doing the following
insert into tablex (field1) values (N'testdata')
it does not display in query analyzer or in the database as armenian.
When I copy this to word it does not convert it.
What else am I supposed to do to get that information to redisplay the correct way and I would appreciate any tutorials or samples you can show or direct me to.

Severe Performance Hit With NCHAR Queries
Nov 22, 2006Hey there :)Sorry if I'm asking a dumb question here, but I'm still quite new to MS SQL,so this problem might appear larger to me than it really is.I'm trying to create a performance test environment for a Ruby on Rails andMongrel setup with an MS SQL Server 2000.The adapter, mssqlclient, uses some kind of "conversion" for unicode, here'sa quote from the homepage:"Automatically translate from proper UTF-16LE nvarchar fields in thedatabase to UTF-8 Ruby Strings you can display in your application"As far as the local DB designer knows, we're not using UTF16-LE nvarcharfields, unless it's something that happens implicitly.Either way, this is how a query from the mssqlclient adapter might look:SELECT TOP 1 * FROM Item WHERE (Item.Itemnumber = N'45783745')Response time the first couple of times was upwards of 20+ seconds, afterthe sql server has "awaken from its slumber", it's roughly 4 seconds.Omitting the "N" from the WHERE clause, response time is in milliseconds (asone would expect, regardless of the fact that there's currently >2.5million items in the table).Any tips on how to resolve this? Is the SQL statement bad, or is it aquestion of configuring SQL Server correctly?Thanks in advance for any help,Daniel Buus :)--http://www.rhesusb.dk
