Collations And Nvarchar
Aug 22, 2007Should a programmer bother using nvarchar for a person's name (special chracters allowed) if I still use SQL_Latin1_General_CP1_CI_AS?

Collations
Nov 2, 2007Hi there. I'm trying to create a copy of a remote database for development purposes. I am useing MySQL, the remote database is in MSSQL. The create table commands contain a collation titled
quote:SQL_Latin1_General_CP1_CI_AS
which MySQL doesn't recognise. The three most similar collations I can find in MySQL are:
quote:
'latin1_general_ci',
'latin2_general_ci'
'latin7_general_ci'
Does anyone know the difference between these collations? And whether any of them is equivalent to the MSSQL code I have to implement?
thanks! Dave
Need Help With Collations
Jul 20, 2005I want to create a database where the table names / column names / SP namesare NOTcase sensitive but where the data in the tables is, so that I canbuild a unique index where 'test' and TEST' is accepted as different.I have tried Installing SQL with a Collation designator with the CaseSensitive option checked- this caused all sp names / column names / table names to be casesensitive - not what I want.I have also tried installing SQL and selecting a SQL Collation and pickingan option from the drop down list. - again this cause everything to be casesensitive - not desiredDo I have to install SQL with a non case sensitive collation, then set eachcolumn in the table to be case sensitive? What if any are the problems I amlikely to come across?ThanksSteve

Feb 4, 2002Hi,
I noticed that when I installed SQL2000,with "typical install",
the default, the following will be used:
SQL collation (dictionary order, case-insensitive, assent sensitive)
sp_helpsort will give
SQL_Latin1_General_CP1_CI_AI
Is there any difference if I choose the "custom install", then and choose
the windows locale which gives the result of sp_helpsort:
Latin1_General_CI_AI
SQL_Latin1_General_CP1_CI_AI is supposed for backward compatibilty, so are
they actually equivalent ??
Any impact or difference we have to be aware of ??
Anyone knows..Thx
Changing Collations...
Mar 2, 2006I have looked thru the forum but have a couple of questions:
1) data base was created with case insensitive collation
2) all the tables were then create (72 tables) and by default got the CI collation on all columns
3) lots of data was added 2GB
4) discovered mistake and altered the database to have case sensitive collation
5)..... how to change all the collations for all the columns without doing them all manually
can i backup the database and change some settings and restore it?
export all the data, drop and recreate tables and import data?
????

Each database has around 180 tables, Ihave changed the collation on DB, but changing collation manually oneach column is a daunting process.

Apr 10, 2007I have developed a tool to allow project developers to easily re-create the entire schema for our base product. The current issue involves setting the correct collation for the customers' region. Our brother company in Germany uses the same db creation tool and scripts, and we here in the US also have customers in South America. My ultimate question is "what subset of collation names would be necessary to provide the project developer?" I could query the database to get all the collation names, but I think it was around 1000 names. Can I query to get a smaller subset of the most relevant collation names?

Collations And Simple Import From A Csv-file
Apr 23, 2007Hello. Here a two different problems that occur one and a while when I try to import a textfile to SQL Server 2005.
I have a flat file connection to a csv-file that originally is a export from an AS4000 DB2 database
This csv-file is defined as a variable length file
Why do SSIS automatically interpret the length of each column as varchar(50)? It does not matter if a define the same file as a fixed lenght file. The problem is that I will get a warning that information in columns will be truncated. I would like to do a direct export to the SQL Server 2005 table with shorter varchar fields. I can solve this by using the task for transforming data types but this only works on the text fields. This task cannot transform a string to a decimal or an integer column in the SQL Server 2005 table. Is there no other way than having a staging table between the text file and the SSIS-data pipe?
I also get a lot of collation or code page errors even if we set the receiving columns to nvarchar and nchar. Is there any good article on this subject? Code page errors
Last question. Is there parameter support in the data reader source connection?
I appreciate all help.
Regards

Unable To Resolve Column Level Collations

I checked for the dtatatype and length between source and destination, both are same. The user have all the required rights on the objects in both source and destination.

Its kind of wierd though....

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.
Updating Systemtables Directly To Change Column-collations
Mar 3, 2005Hi there.
Is there any way to update the system tables directly, to alter the collations of the columns in the user db's?
I've tried the script below:
UPDATE Syscolumns SET collation = 'SQL_Latin1_General_CP1_CS_AS' WHERE name = '<AddrCode>'
AND id = object_id('<Compliance>')
but, I get the following error message:
Server: Msg 271, Level 16, State 1, Line 1
Column 'collation' cannot be modified because it is a computed column.
Can you please help me! I need to do thousands of these, and most of them has constraints on, so my script I generated to do the ALTER TABLE.... ALTER COLUMN does not suffice.
Thanks.
Why Do Some System Views Have Columns With Different Collations Then The Default Collation?
Oct 8, 2007I'm recreating many of my DBA scripts that no longer work in 2005 due to the rework of system tables. It's a risk I lived with knowing that someday the system tables would change. I'm now encountering collation problems, which I do not understand. I know how to fix the problem, but I don't know why the collation issues exist in the first place.
Run the following command.
Select * From sys.all_objects a JOIN master..spt_values b on a.type = b.type
You will receive the following error.
Msg 468, Level 16, State 9, Line 1
Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AS_KS_WS" in the equal to operation.
Now run sp_help 'sys.all_objects' and look at the collation defintion for columns "type" and "type_desc". In my environment they have a collation of Latin1_General_CI_AS_KS_WS. This is different then the overall default collation of SQL_Latin1_General_CP1_CI_AS, thus causing the error.
My question is why did Microsoft need to make this collation different for these columns?
Any ideas?
Thanks, Dave

Nvarchar(max)
Dec 11, 2007Does anyone know the formula to calcuate the space occupied by an nvarchar(max) column for the purposes of sizing a table?
View 1 Replies View RelatedUsing Nvarchar(MAX) Instead Of Nvarchar(#)
Feb 19, 2008Is it bad form to use nvarchar(MAX) in place of column types with specific lengths like nvarchar(50)? Are there performance issues? Because to me (a novice), it appears that I would save space by using nvarchar(MAX) everywhere.
Same question applies to varbinary(MAX) as well.

NVARCHAR(MAX)
May 22, 2008
I have an SSIS pkg, that gets data from Lotusnotes db and loads into SQL Server, using ODBC Driver for Notessql driver . I have a comments, field, in Lotusnotes which has comments>8000 chars in lotusnotes. Hence I created my destn SQL Table with datatype NVARCHAR(MAX) so that it can uplaod the comments that are >8000 chars.
However, every time I run the ssis pkg , the destn table is bringing only 250 chars ONLY in the comments field , and truncates the rest of the chars.
And I see the reason is because, on my ODBC Serttings for Lotusnotes, There is a section for NOTESSQL options
where the "Max length of text fields" set to 254. hence it brings only 254 chars into SQL.
However, If I increase that option "Max length of text fields" to 8000 or some higher number, the sssis package errors out on the datareader source itself, err is"
"The output column 'comments' has a length that is not valid.
Pl advise how can I load all the comments which are more than 8000 chars from lotus notes into SQL, AND KEEPING THE ODBC settings, the "Max length of text fields" TO 254 Only.
Order By Nvarchar
Feb 2, 2007I have a scenario to sort on an nvarchar (50) field and I need to keep any changes to the sproc in the ORDER BY clause if possible. This field will contain strings such as...
abc-217c, abc-15a, abc-9a, abc-7b, abc-17ar, etc...
The issue I'm having is when the records are sorted, they are returned as...
abc-15a, abc-17ar, abc-217c, abc-7b, abc-9a,etc...ordering numerically on the first numeric character in the string ie, 1,1,2,7,9)
However, I need the numeric component to be treated as a whole number and order in this fashion...
abc-7b, abc-9a, abc-15a, abc-17ar, abc-217c (7,9,15,17,217, etc)
I feel pretty sure that this issue has come up before...can anybody provide a working example that would provide a simple(or not so simple) solution?

I'm trying to convert a nvarchar datatype to int

VARCHAR Vs NVARCHAR
May 16, 2006So I have an existing table that looks like:
ID BIGINT
VAL VARCHAR(128)
I am converting this table to something that will be multi language compliant. My question is, I know that NVARCHAR's take double the space of a VARCHAR. Do I actually need to double the length of the VAL field to store the same amount of data or does the DB handle that?
Basically I want to store a 128 character NVARCHAR.. do I need to set my table up like this:
ID BIGINT
VAL NVARCHAR(256)
or
ID BIGINT
VAL NVARCHAR(128)
