SQL Server 2014 :: Case Sensitive Collation Causing Cardinality Warning
May 18, 2015
Over the weekend I decided to give it the ability to do a case sensitive character swap. Updating the code was pretty straight forward but when I was through, I noticed that I was getting Cardinality Estimate warnings that I wasn't getting before.
Anyway, here is some test data and two versions of the executed SQL (the base code is all dynamic and the two code versions are the result of toggling the @MatchCase parameter).
/* ========================================
CREATE TABLE
======================================== */
CREATE TABLE [dbo].[PersonInfoSmall](
[PersonID] [BIGINT] NOT NULL,
[FirstName] [NVARCHAR](50) NOT NULL,
[MiddleName] [NVARCHAR](50) NULL,
[LastName] [NVARCHAR](50) NOT NULL,
[code]....

We need to install CI database on CS server, and there are some issueswith stored procedures.Database works and have CI collation (Polish_CI_AS). Server hascoresponding CS collation (Polish_CS_AS). Most queries and proceduresworks but some does not :-(We have table Customer which contains field CustomerID.Query "SELECT CUSTOMERID FROM CUSTOMER" works OK regardless ofcharacter case (we have table Customer not CUSTOMER)Following TSQL generate error message that must declare variable @id(in lowercase)DECLARE @ID INT (here @ID in uppercase)SELECT @id=CustomerID FROM Customer WHERE .... (here @id in lowercase)I know @ID is not equal to @id in CS, but database is CI and tablenames Customer and CUSTOMER both works. This does not work forvariables.I suppose it is tempdb collation problem (CS like a server collationis). I tried a property "Identifier Case Sensitivity" for myconnection, but it is read only and have value 8 (Mixed) by default -this is OK I think.DO I MISS SOMETHING ????

Yesterday I received a response to my CI/CS Collation problem and therecommendation was to try and restore a CI Collation database to a CSCollation database. After creating a blank CS database a full restore(Force restore over existing database) does change the Collation toCI. I'm unsure as to how I can restore without changing theCollation. Any suggestions?

Dear SQL Experts,
Can I change an existing 2000 sql server to case-sensative?
Books on-line tell you how to create one during setup, but requirements around here dictate that I chage my existing setup.
Any help would be greatly appreciated.
Thanks

alter database test collate Latin1_General_CS_AS
But to my horror it made the tables name case-sensitive .
Plz help me out asap.
Thanx in advance

I have just been given a new SQL Server 2000 box to look after in production. I just tried to run a standard t-sql script I use for setting up backup jobs and so on. However, it failed with a long list of errors - quite a surprise at first since I have run the same script on many other servers wihtout a hitch. On close examination, the problem appears to be that the new serer is setup with a server default collation... Latin1_General_BIN (I think a binary based collation makes this a case sensitive server).
This is quite an urgenet one since I have to get this wrapped up today. I don't think I can change the server's default collation without a lot of red-tape. Is there a quick way to run my scripts in a 'case insenstive' context within Query Analyzer? If so, how?
Thanks in advance,
Clive

I have a set of data where a column contains titles which have been formatted as follows:
"FirstWordSecondWordThirdWord...." etc.
That is, all the words have been concatenated but can be visually separated by their capital first letters.
For reporting purposes, I need to break this column into the separate words so that it looks like:
"First Word Second Word Third Word...." etc.
how this can be achieved?

I have a table called SrcReg which is having a column name called IsSortSeqNo smallint. I am mapping this column in SSIS and the problem comes when I try to execute against different database which has this table but the column name as ISSortSeqNo. I mean both databases having same name but one with upper case. So SSIS fails executing due to meta validation issue.Is there any way to check whether the column name is in small case or upper case through query?

I have a sql snippet from a 3rd party application that will not complete its transaction. The SELECT statement executes but does not finish. Instead the statement just sits in AWAITING COMMAND for 1000 seconds then dies, thus killing the UPDATE statement that is supposed to follow.
The CROSS JOIN and CROSS APPLY seem suspect.

@p0 DATETIME,
@p1 INT,

I just ran into an issue with cascading locks due to a SPID on one of my production servers. When researching the lock, I noticed that there was no sql text. SP_Who 2, nor the following query captured anything,
SELECT sqltext.TEXT
, sqlplan.query_plan
, req.session_id
, req.status
, req.command
[Code] ....
I spoke to the user causing the lock and he ran into a visual basic error when this occurred and didn't close out that window. So my guess is that it's due to an uncommitted transaction. However, shouldn't I still see something if that was the case?

I installed the samples and tutoriales on the same server as SQL Server 2005 and VS 2005 Team Suite.
Living in Belgium, the local settings are:
language = Duch (Belgium)
code page = 850
e.g. in the database samples (AdventureWorks database €“ AdventureWorks Warehouse database)
my date notation is: 26-12-2005
my number notation is: 1,0013016921998599
all demo samples and tutorials are developed using
language = English (United States)
code page 1252
e.g. in SampleCurrencyData.txt
the date notation is: 12/26/2005 00:00:00
the number notation is: 1.0013016921998599
I do not have any problems to test the diferent services (Data Base Engine Services, Analysis Services, reporting & notifications services ..) but I do not succeed to deploy any samples of integration services !
e.g. for Integration Services Tutorial - lesson 1: €śCreating the Project and Basic Package€?
there are no error messages, 1097 rows are processed
but, checking the result in the database, no data is updated in the FactCurrencyRate table of the AdventureWorksDW database !
Why?
- is the problem related to the local language settings? how to solve this?
- what is the influence of the code page ? is there any compatibility between 1252 and 850 as code page?
- Server collation (e.g. Latin_1_General_CI_AS) is reported as key for the Unicode notation for character strings but what about notation of numbers?
- when to use float data type DT_R4 or DT_R8?
- I have remarked that the DT_DBTimeStamp is undependent from the source time notation €“ Is this correct?
- what is the difference between DT_Date and DT_DBDate or DT_DBTime, or DT_DBTimeStamp?
- Is Integration Services dependant of the local settings of the database engine?
- how to set / modify additional regional properties in a SSIS and SSRS package?
- how to change the default setting of the Flat File Connection Manager [starting the wizard, the local setting for the language €“ Dutch appears and this is OK for me but as codepage appears 1252 (ANSI Latin) and this is not OK as my server code page = 850]?
- how to work with e.g. US based data as source and Belgium settings for reports?

We are consolidating some old SQL server-environments from 'OLD' to 'NEW' and one of our vendors is protesting on behalve of the collation we use on our 'NEW' SQL server.
Our old server (SQL 2005) contains databases with collation SQL_Latin1_General_CP1_CI_AS
Our new server (2014) has the standard collation Latin1_General_CI_AS
Both collations have CI and AS
From experience I know different databases can reside next to eachother on the same Instance.
The only problem could be ('could be !!') the use of TempDB with a high volume of transaction to be executured in TempDB and choosing for Snapshot Isolation Level ....
The application the databases belong to is very static, hardly updated, and questioned only several time per hour (so no TempDB issue I guess).
using different databases using a different collation running on the same instance?

Dear everyone,
I am doing Login webform (C# .NET web application) with SQL Server 2000.
The staff table is to store authenticated user info.
But when I test it, I found that the password can be case insensitive, i.e. 'A0001' should be correct password, but 'a0001' can allow login.
Could anyone tell me how to solve this problem??
Thanks you very much!!

//try and catch SqlException error

Hi all,
There is a requirement to perform a case-sensitive search
on a column in table. The installation of SQL Server is
case-insensitive...
Eg.: select * from t1 where c1 = 'abcd'
should return only rows where c1 = 'abcd' and not 'ABCD'
or 'Abcd' or any other.
I understand that this can be done using the CONTAINS
predicate using Full-text indexing.
select * from t1 where CONTAINS(c1,'abcd')
Is this the right solution to the problem? Has someone
had experience implementing this?
Thanks in advance.
