I've written a stored proc which passes in an SqlString parameter and compares it with an SqlString read from an SqlDataReader.
I get the following exception:
System.Data.SqlTypes.SqlTypeException: Two strings to be compared have different collation.
Any ideas on collation inside CLR stored procs?
Thanks.
I'm using SQL Datatype SqlString, so I'm not sure what is going wrong...any help?
Here is a shortened version of the issue: Code and then Full Error Message.

Hello,
I've restored a SQL Server 2000 database with a Latin1_General_BIN collation from a .dmp file to a SQL Server 2005 server with a default collation of SQL_Latin1_General_CP1_CI_AS. When I try to change the database collation I get hundreds of the following error:
The object 'CK_PM10200_GLPOSTD_00AF8CF' is dependent on database collation. So, in this case, is it even possible to change the collation if there are objects in the database that are dependent on it?
Thanks,
Bruce
I changed the default collation of a database and every table within that except sysDiagrams , which I can't even through the designer .
View 9 Replies View RelatedI have a whole bunch of bit fields in an SQL data base, which makes it a little messy to report on.
I thought a nice idea would be to assigne a text string/null value to each bit field and concatenate all of them into a result.
This is the basic logic goes soemthing like this:
select case new_accountant = 1 then 'acct/' end +
case new_advisor = 1 then 'adv/' end +
case new_attorney = 1 then 'atty/' end as String
from new_database
The output would be
Null, acct/, adv/, atty, acct/adv/, acct/atty/... acct/adv/atty/
So far, nothing I have tried has worked.
Any ideas?
I am using SQL Server 2008. In ServerProperty function, there are two properties called “Collation” and “CollationID”. In some cases, I will only know the CollationID. Is it possible get the collation name from the CollationID? Is there a function called CollationNameFromID?

THANK YOU
There is no doubt that SSIS has been designed to build on the lessons learned from DTS but in one respect I think that there may have been a backward step and that is ease of use. A big attraction (a hallmark even) of DTS was that you could configure a package to move data between data sources and destinations in minutes.
When you first start using SSIS this is far from being true. I tended to get a lot of errors (many of them not very helpful) relating to stored procedure parameters, truncation of data etc. Looking around this Forum I think that I am not alone. This is partly a learning curve issue but I think that the learning curve is much steeper for SSIS.
.
This is not a plea to go back to DTS, we must move on, but I would like to think that there will be an emphasis on improving ease of use for SSIS going forward.
For the record two general improvements that I can see in SSIS (over DTS) are:-
1. A more logical structure.
2. The ability to easily set any Package Property, not just Variables at run time.
I am running an application on one NT Server, running against SQL Server 6.5 sp 3, and SQL 7 with sp1 applied.
The application is a 'data migration' type application - ie heavy insert and update workload - against many (50+ tables) with many different SQL statements.
The SQL 7 server is configured with 'floating' memory.
On SQL 7 - I am experiencing very high page faults/second for the sqlservr process - sometimes peaking at over 1,000. I was under the impression any number greater than 10 indicates a problem with system performance.
The same application, same data, same NT configuration etc against SQL 6.5 does not page fault. SQL Server 6.5 completes the work faster than 7.
Could anyone help me understand what's going on ?
Thanks in advance.
Working on some new code, I'm coming across WHILE loops used instead ofcursors. I was curious if anyone had any stats on how the speed ofdoing this compares to the speed of a cursor. I typically avoidcursors for performance sake, but I'm not sure how this avoids thespeed hit of a cursor, since it's doing essentially the same thing.Many thanks.

Hi,
I have migrated my app from VB to VB.Net. A 3-tier app with remoting and COM+.
I am experiencing a long wait time of about 3 times higher than what it would take in the VB App.
I am using DataAdapter.FiLL method to fill the datatable.
I have tried.
Using DataReader ( Made the things worse )
Using BeginLoadData and EndLoadData
Creating a Dataset and calling fill with the dataset so that the round trip to the middletier is saved to bring the SQL.
But i feel now that whatever is done. the problem is with the fill method only?
Is there any alternative?
Please suggest. It is one of the most important thing which if not possible may lead to scrapping up idea of upgrading to .Net.

Hi,
We have Asynchronous Database Mirroring on SQL Server 2005 SP2 Entprise Edition/Windows 2000 Advanced Server. We noticed that log sent rate is quite low (average 1.3 MB/sec) in most of the cases whereas "Log bytes flushed/sec" is high (1.4 MB/sec) as a result Log send queue keeps on increasing and finally taking all the transaction log space. Our disk queue length is always in range of 0.01. And prinicipal and mirror servers are on local LAN.
I tried on low end server and high end server and in both cases Log sent rate is approx 1.3 MB/sec (Maximum 4 MB/sec).
Is there any limitation on Log sent rate?
How can we improve on log sent rate? Since both servers are on local LAN, network bandwith does not seems to be an issue.
Any help is greatly appreciated.
Thanks,

i was using sql 2000, the database contains 500+ tables, 3000+ sp.
i moved to sql 2005 and found problem on generating script (right click database -> tasks -> generate scripts).
i need to generate the table relations.... it is very very slow compared to sql 2000 which is done in about 30 seconds to few minutes.
i already tried many ways including set options to false which in my thought could speed up a lot...but still very slow.
average generate script time with sql 2005 (sp 2): 70-90 minutes.
average generate script time with sql 2000 (sp 4): 2-3 minutes.
can anyone tell why ? thx in advance
The source for this problem can be found http://www.wellytop.com/SQLProblem.zip
This test creates two threads each with a database connection and uses transactions to insert values into the same table.
The objective of this test is to check that a thread cannot read the results from a pending transaction on a different thread.
In effect this checks dirty reads do not happen and transaction locking.
The test runs correctly and displays "PASSED" with MySQL indicating the transaction and threading worked.
When running with MSSQL Express 2005 it reports a deadlock error during a transaction.
It's not really possible to re-run the transaction and I would like MS SQL to operate similar to MySQL, i.e. MySQL waits for the other transaction to finish before the next transaction can operate on those table rows. I'd like to use MSSQL but I am wondering why this error doesn't happen with MySQL and so have, for the moment, chosen to use it as my preferred database solution.
I have experimented with transaction isolation levels and this doesn't seem to solve the problem.
I've tested this with a fresh install of Windows XP SP2 and no firewall turned on.
To run this test with MSSQL Express2005 use the ODBC Data Source Administrator (odbcad32.exe) to create a data source named MyExpressTest and attach this to an empty database that has been created with the default values. Enable the #define MSSQL in the coude otherwise it tests with MySQL.
To run this test with MySQL (to show how this test should work) use the ODBC Data Source Administrator (odbcad32.exe) to create a data source named mySQLNewTest and attach this to an empty database that has been created with the default values. Comment out the #define MSSQL to switch to MySQL mode.

Field is not listed as text in any of the databases it is a varchar(255) - and that can be changed if that is what causes the issue.
But here is my syntax which produces the error Msg 421, Level 16, State 1, Procedure, Line 2
The text data type cannot be selected as DISTINCT because it is not comparable.
DECLARE @c NVARCHAR(MAX)

where [abcd] IS NOT NULL
), c2 AS (
SELECT Row_Number() OVER (ORDER BY table_name) AS r

Hi,Has any one ever compared the performance of calling a DataTable'sSelect method with a stored procedure doing the same thing?My point is:dataRows = DataTable.Select(filter) is better orPassing paramters to stored procedure?The datatable holds about 500-700 rows at any given time.If I select one of the approaches the business logic will go intorespective layers.With dotnet in picture what would be a good approach- Have the data in Datatable and do a filter on the data or callstored procedures which has been the convention.Can some one pl. suggest?

I am currently in the process of setting up an SQL Server Express installation that comes packaged with an application I have written. My problem is that I want to use SQL Server user management (not just windows users) which work fine if I set them up manually. I started writing a script that I have SSEUtil execute once the application is fully installed (a step in my installation script) which sets up the users and passwords etc. The script is similar to the following:
USE [DBName]
GO
EXEC sp_DropUser 'user1'
EXEC sp_DropUser 'user2'
EXEC sp_DropUser 'user3'
EXEC sp_DropUser 'user4'
GO
USE [master]
GO
EXEC sp_DropLogin 'user1'
EXEC sp_DropLogin 'user2'
EXEC sp_DropLogin 'user3'
EXEC sp_DropLogin 'user4'
GO
CREATE LOGIN user1 WITH Password = 'user1', CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
CREATE LOGIN user2 WITH Password = 'user2', CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
CREATE LOGIN user3 WITH Password = 'user3', CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
CREATE LOGIN user4 WITH Password = 'user4', CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO
USE [DBName]
GO
EXEC sp_AddUser 'user1'
EXEC sp_AddUser 'user2'
EXEC sp_AddUser 'user3'
EXEC sp_AddUser 'user4'
GO
ALTER USER user1 WITH DEFAULT_SCHEMA = MySchema
ALTER USER user2 WITH DEFAULT_SCHEMA = MySchema
ALTER USER user3 WITH DEFAULT_SCHEMA = MySchema
ALTER USER user4 WITH DEFAULT_SCHEMA = MySchema
GO
REVOKE ALTER,DELETE,INSERT,SELECT,UPDATE ON MySchema.Table1 FROM MyRole
REVOKE ALTER,DELETE,INSERT,SELECT,UPDATE ON MySchema.Table2 FROM MyRole
REVOKE ALTER,DELETE,INSERT,SELECT,UPDATE ON MySchema.Table3 FROM MyRole
REVOKE ALTER,DELETE,INSERT,SELECT,UPDATE ON MySchema.Table4 FROM MyRole
GO
EXEC sp_DropRole 'MyRole'
EXEC sp_AddRole 'MyRole'
GO
GRANT ALTER,DELETE,INSERT,SELECT,UPDATE ON MySchema.Table1 TO MyRole
GRANT ALTER,DELETE,INSERT,SELECT,UPDATE ON MySchema.Table2 TO MyRole
GRANT ALTER,DELETE,INSERT,SELECT,UPDATE ON MySchema.Table3 TO MyRole
GRANT ALTER,DELETE,INSERT,SELECT,UPDATE ON MySchema.Table4 TO MyRole
GO
EXEC sp_AddRoleMember 'MyRole','user1'
EXEC sp_AddRoleMember 'MyRole','user2'
EXEC sp_AddRoleMember 'MyRole','user3'
EXEC sp_AddRoleMember 'MyRole','user4'
GO
Now if I run this script from within SQL Server Management Studio it executes perfectly. The logins add, the role is added, each user is added to the database logins and assigned to the role, the schema is set correctly on each user.
Then when I try to run the exact same script from the SSEUtil application (SSEUTIL -s PCNAMEInstance -run USERS.SQL), it processes everything, except the Logins.
This is frustrating as it means to install for a client I would need to either get them to open the management console and run the script from there, or I have to go to site just to setup users.
Am I on the right track? Or is there another way to automate the adding of Logins?
Thanks in advance,

To extract data from an ODBC source, try the following:
Add an ADO.Net Connection Manager.
Edit the Connection Manager editor and select the ODBC Data Provider
Configure the Connection Manager to use your DSN or connection string
Add a Data Flow Task to your package.
Add a Data Reader Source adapter to your data flow
Edit the Data Reader source adapter to use the ADO.Net connection manager that you added.
Edit the Data Reader source to query for the data you wish to extract.

Using the steps outlined above as described by Donald Farmer in another post on this forum, I have created an SSIS package which retrieves data from Lotus Notes 6.55. The DSN referenced by the ADO.Net Connection Manager connects to Lotus Notes via the NotesSQL ODBC driver 3.02g.
When I execute the dataflow, data is transferred from Lotus Notes, but the data transfer rate is extremely slow compared to SQL 2000 DTS. In SQL 2000 DTS, we can retrieve just under half a million records from Lotus Notes in about 13 minutes. Utilizing the same DSN on the same machine, SQL 2005 SSIS completes the transfer in about 57 minutes.
Is there anything that can be done to improve the performance in SSIS to retrieve data from Lotus Notes via ADO.Net ODBC?
Thanks!
I have a fact -REVENUE table of accounts, each account can have multiple instances . And I have an Aggregate that summarize the latest occurrence of a revenue for each account ( in a chosen Period ) :

How can I find the percent of one of the lastest accounts Compared to all accounts? Assuming i have connect Dim_Time ( Y-Q-M-D ) to Revenue_Date, how can i find the percent of one Month Compared to all the months in the Quarter ( And so on hierarchies ) ?

I have a complex view in my sql 2005 database.
The view returns a column that could be null (as the result of a left outer join).
The coulmn that is returned is an integer.
Everything works fine if I run the view from SQL 2005 Management Studio.
My column value is always null if I use ADO.NET's SqlAdapter to return a DataTable.
Has anybody seen this behaviour before?
Any help appreciated.

Hi,
I have a report in SQL Reporting Services 2005 which calls a stored proc and the report takes a very long time to run and sometimes returns zero records. But when i run the stored proc in query analyzer it takes about 4 seconds!!
I have checked the execution log on the RS using the below sql:
Code Snippet
use ReportServer
Select * from ExecutionLog with (nolock) order by TimeStart DESC
It shows that i have a large amount of time for the dataretrieval (601309ms, about 10mins) and does not return any records most likely because of a query timeout:
TimeDataRetrieval TimeProcessing TimeRendering Source Status ByteCount RowCount
601309 2227 3 1 rsSuccess 4916 0
The weird thing is that when i run it in query analyzer, i get about 400 records in 4 seconds !!
I dont understand what RS is doing to take up so much time like this to retrieve data.
The report is very simple - it basically returns the records straight out into a table.
The only thing I somewhat suspected was a parameter data type conflict between RS and SQL, specifically dates. I have a start and end date parameter in the report - i tried specifying this as date and string to see if it made any difference but it didn't.
Any help would be greatly appreciated.

Can any one please tell me how to get the complete error description for example when i dont Redirect Row for Error in OLEDB Source i get a detailed error message with column name as
[RCheck [385]] Error: There was an error with input column "CHECK_STATUS" (456) on input "OLE DB Destination Input" (398). The column status returned was: "The value could not be converted because of a potential loss of data.".
But when I set Redirect Row for error and use the Script component to log them into a Table with ErrorDescription based on ErrorColumnID it only gives me this.
The data value cannot be converted for reasons other than sign mismatch or data overflow.
Thanks

do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like
SELECT ... ,CASE enddate WHEN null then 1 else 0 END calcd name
FROM...
WHERE ... and calcd name in (@variable)
Need to know if the varchar datatype field will ingore leading zeros when compared with numeric datatype ?
create table #temp
(
code varchar(4) null,
id int not null

insert into #temp
[Code] .....
for complex views should I use "where" statements or "joins" in terms of performance?
Which one is faster?

Hi:
I have a website and related database in English version, now I am trying to start with other language, such as Chinese.
The first problem I am facing is: search a user name when user name is Chinese:
For example: English version: SELECT u_name FROM Users WHERE u_name = 'eric', it will return a value, but if I type: SELECT u_name FROM Users WHERE u_name = '艾瑞克', even if the table cell has the 艾瑞克 record, it won't return anything.
Search online, there are a lot of articles, since I am pretty new for this, can you let me know where to start? How to change the collation for the existing db, do I need to create stored procedure for the search?
I would like to solve this problem start from my MSsql 2005 database. If that works fine, then I will go to my web application.
Thanks a lot.

Hi ,
I would know what is the simplest (and the more reliable) method to convert an entire db from a collation to another...
Thanks
