Long Names
Mar 6, 2001
I have created a database which has a table whose name is 128 characters long; this table has a column whose name is 128 characters long. When I issue the command sp_helpconstraint table_name, SQL Server 7 returns the message "string or binary data would be truncated."
Any suggestions?
Thanks!

Thank you for taking the time to read this, I need all the advise and help I can get on this ... so please post anything you think would work ... A little confused I am:
Have a database table called "people" with "person name" and "ID" field. My ASP.NET application mainly stores articles in article table. An article's Article text mentions various people's names in different combinations (e.g. John, Smith, John Smith, Smith John, etc)
Is there any way, I could compare the article text stored in article table with people table and get the people from people table along with their ID's who have been mentioned in that article? ... so in an article "i love john smith ... and i think Mr smith has always been helpful", I get John Smith back...
Not too sure being honest, what is the best way of implementing this, looking for the most efficient way, probably using XML? SQL Query or may be ASP.NET's code behind?
Thanks once again for taking the time.
Cheers,
Tyro

I'm posting this in the ClickOnce forums as well...
My application doesn't include the .mdf and .ldf files, rather it creates the database the first time the application is run using a script that is included in the build. I want to create the database in the ClickOnce data directory. The problem I'm having is that SQL Server complains when I execute the CREATE DATABASE command as follows:
CREATE DATABASE [C:Documents and SettingsxxxxxLocal SettingsApps2.0DataPQCK6EXN.5KGAW630RPT.VGOifie..tion_014028c05b1d6ec6_0001.0002_0e86966f19503c89DataiFieldMobile.mdf] ON PRIMARY

LOG ON
( NAME = N'myDatabase_log', FILENAME = N'C:Documents and SettingsxxxxLocal SettingsApps2.0DataPQCK6EXN.5KGAW630RPT.VGOifie..tion_014028c05b1d6ec6_0001.0002_0e86966f19503c89DatamyDatabase_log.ldf' , SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
END
Here's the error:
System.Data.SqlClient.SqlException "The identifier that starts with 'C:Documents and SettingsxxxxxxLocal SettingsApps2.0DataPQCK6EXN.5KGAW630RPT.VGOifie..tion_014028c05b1d6ec6_0001.00' is too long. Maximum length is 128."

I am designing a package to export staging tables into a flat file.The names of the tables will be: TableAStaging_YYYYMM and TableBStaging_YYYYMM. As you can see the names of the tables will be changing each month.
The flat files will have similar naming: C:MyPathFlatFileTableAStaging__YYYYMM and C:MyPathFlatFileTableAStaging__YYYYMM.I want to run the package as an sql job in two steps, one for each table.I need to dynamically pass the table names and file names (together with the path) to the IS package.

As part if a recent requirement I have to export Chinese/Singaporean names in a CSV file. The data in the tables is a NVARCHAR(256).
I am using a FlatFile Connection manager where all the present columns from the table are exported as NVARCHARs. My understanding was that the Chinese/Singaporean names would blend seamlessly with NVARCHARs in place. But, they get garbled when pushed to the CSV.
Here is the connection manager setup
There are a lot of suggestions of fixing this by copying/pasting to a notepad file and changing the formatting... But I cant do that since the file is generated using a schedules SSIS package. How can I tweak the process to fix the issue?

Hi
I was wondering if anyone has an idea of how we could find the table names and column names of the tables in our Sql server database at runtime/dynamically given our connection string? Please let me know.

I'm going to be setting up DB mirroring between two SQL Server 2005 boxes. Since these are on two different servers, can the instance names be the same? Is there any reason NOT to do so if the mirror server is going to be used exclusively for DB mirroring?
For example: if the my primary DB is located on SERVER1INSTANCE1, can the mirror be SERVER2INSTANCE1 or do the instance names have to be different even though they're on different boxes.
Thanks!

I'm trying to do an update query that looks like this:
UPDATE
PAEMPLOYEE
SET PAEMPLOYEE.LOCAT_CODE = EMPLOYEE.PROCESS_LEVEL
FROM
PAEMPLOYEE A
JOIN EMPLOYEE B ON A.EMPLOYEE = B.EMPLOYEE
It's erroring out on the Employee prefix B.EMPLOYEE saying:
..."does not match with a table name or alias name used in the query"
Is it wrong or will it cause problems to have a field name the same as the table name?

Hello there. I'm trying to populate a drop down box with a list of all available instances of SQL server (express or not) available on a network. To list all instances I'm using EnumAvailableServers() in SmoApplication.
The issue is that the Instance column in the returned data table is always empty, and both the Name and the Server columns contain the same string -- the name of the computer the SQL server is installed. Locally I have SSE installed, the instance name is <computer_name>SQLEXPRESS, however, using Smo I can't seem to get to the either full instance name or just the instance name. I can't assume SQLEXPRESS, since there may be more than one installed.
Alternately I used EnumRegisteredServers() in SmoApplication.SqlServerRegistrations and that, while returning instance information (can be retrieved from the RegisteredServer in the returned collection), doesn't always return the remote SQL servers in the list.
Any idea how can this be done? Maybe I'm going at it the wrong way, maybe there's another class / method I need to use to retrieve all instances?
Thank you

For instance, say the date of an update is : 16/10/2007 15:16:03 I want the Label to say "Happened over 2 months ago" etc.Now ive tryed to use an IF statment but I cant seem to get it right : DateTime dt = Convert.ToDateTime("16/10/2007 15:16:03"); if(dt.ToShortDateString() == DateTime.Now.ToShortDateString()) { //happened today if(dt.ToShortTimeString() == DateTime.Now.ToShortTimeString()||dt.ToShortTimeString() < DateTime.Now.AddMinutes(-1).ToShortTimeString()) { //happened within a minute UpdateLabel.Text = "About A Minute Ago"; } } else if (dt.ToShortTimeString() == DateTime.Now.AddDays(-1).ToShortTimeString()) { //happened yesturday UpdateLabel.Text = "Updated Yesturday"; } else if (dt.ToShortDateString() == DateTime.Now.ToShortDateString() || dt.ToShortDateString <= DateTime.Now.AddDays(-7).ToShortDateString()) { UpdateLabel.Text = "Updated Last Week"; }Any ideas where Im going wrong?

Please Comment.

You should use readtext and writetext to access text column. By the way, nchar and nvarchar can hold up to 4000 characteres.

Hi
When writing a stored procedure,sometimes the line of sql code could be very long and be more than 128 caracthers.
I got an error message saying that the code is vey long and the maximum is 128.
But at the same time, this is erratic in MSSQL server because it works sometimes even with a line of code of more than 800 caracters...
Have you ever experienced the same problem??
What is the solution?

Hello.
I have a query that takes 1,5second to execute, but only 150ms of CPU. The query is quite simple, just one where statement against a clustered index.
SQL Server Execution Times:
CPU time = 156 ms, elapsed time = 1595 ms.
SELECT column1, column3, column4, ..., column10 FROM table WHERE column2 IN (37, 41, 43, 45, 49, 53, 55) ORDER BY column3 DESC
|--Sort(TOP 1000, ORDER BY:([u].[LastActivityDate] DESC))
|--Clustered Index Seek(OBJECT:([MP].[dbo].[__searchtest].[cix___searchtest_] AS [u]), SEEK:([u].[searchparamid]=37 OR [u].[searchparamid]=41 OR [u].[searchparamid]=43 OR [u].[searchparamid]=45 OR [u].[searchparamid]=49 OR [u].[searchparamid]=53 OR [u].[searchparamid]=55 OR [u].[searchparamid]=59) ORDERED FORWARD)
I have tried to rewrite the query to an INNER JOIN instead.
|--Sort(TOP 1000, ORDER BY:([u].[LastActivityDate] DESC))
|--Nested Loops(Inner Join, OUTER REFERENCES:([spal].[number]))
|--Index Seek(OBJECT:([MP].[dbo].[__search_parameters_lookup].[IX___search_parameters_lookup] AS [spal]), SEEK:([spal].[hash]=-1726604993) ORDERED FORWARD)
|--Clustered Index Seek(OBJECT:([MP].[dbo].[__searchtest].[cix___searchtest_] AS [u]), SEEK:([u].[searchparamid]=[spal].[number]) ORDERED FORWARD)
but the query still takes 1,5 seconds.
It spends 59% (according to execution plan) of sorting. 14% for the index seek of the __search_parameters_lookup table and then 24% of a clustered index seek of the __searchtest table.
How come it only uses that small of CPU but it still takes 1,5 seconds? It seems to be reading from memory as well so it shouldnt be an IO-problem?
The index I have on the table is a clustered index on (column 2).
Any ideas of how I can improve this? I have tried with DTA, also with a non clustered index on column3.
If I remove some columns from the SELECT-list the query will execute alot faster:
SQL Server Execution Times:
CPU time = 32 ms, elapsed time = 32 ms.
Booth the CPU and the elapsed time goes down and now appears to be more normal.
So there seems to be a problem caused by data transfer.
I tried to do a remake and normalize the table and when I do that I get the query execute with a speed of 400ms CPU and 400ms total. And this is still the exact same result, so why does it only spend 400ms of "rendering" or fetching the data when the tables are normalized but 1500ms when its denormalized?
Any ideas?

Hi,I am still not very proficient in SQLServer. So apology if thequestion sounds basic.We have a script to clean old unwanted data. It basically deletesall rows which are more than 2 weeks old. It deletes data from33 tables and the number of rows in each table runs into few millions.What I see in the script (not written by me :-) ) is that all data isdeleted within a single BEGIN TRANSACTION and COMMIT TRANSACTION. AsI have background in informix, such an action in Informix may resultin "LONG TRANSACTION PROBLEM". Does SQLServer have a similar concept.Also won't it have performance problem if all rows are marked lockedtill they are committed.TIA.

this executes fine but the optput is as

What is this?
how could i execute such long commad using CMDSHELL?

Problems Encountered Upgrading SQL 2005 SP1 to SQL 2005 SP2 (9.0.3042.1):
In Summary:
Maintenance Plans Broken
Database Mail Broken
Reporting Services Report Viewer web part displays US Format dates instead of report design English-Australian. .
In Detail:
Microsoft SQL Server 2005 SP2 was downloaded from Microsoft.com. This download occurred after 5 March 2007 and the file version was 9.0.3042.1 (SQLServer2005SP2-KB921896-x86-ENU.exe)
During the Installation of SP2 by a Domain Administrator an error occurred on the Database Engine. A Hotfix Exception was raised and the setup completed with errors.
The Error Log reported a problem:
----------------------------------------------------------------------------------
Product : Database Services (MSSQLSERVER)
Product Version (Previous): 2047
Product Version (Final) :
Status : Failure
Log File : C:Program FilesMicrosoft SQL Server90Setup BootstrapLOGHotfixSQL9_Hotfix_KB921896_sqlrun_sql.msp.log
Error Number : 29534
Error Description : MSP Error: 29534 Service 'MSSQLSERVER' could not be started. Verify that you have sufficient privileges to start system services. The error code is (1067) The process terminated unexpectedly.
----------------------------------------------------------------------------------
The SQL Server service could not be manually started. An error was reported in the event viewer:
One or more files do not match the primary file of the database. If you are attempting to attach a database, retry the operation with the correct files. If this is an existing database, the file may be corrupted and should be restored from a backup.
It was noted that a new file mssqlsystemresource.ldf had been copied to the %data% folder.
Note: As part of separating data and log files, both the master and mssqlsystemresource databases had been previously moved to another volume %data% whilst their respective log files had been moved to a separate volume also %log%. This had occurred after SP1 was initially installed and months prior to the SP2 install using Microsoft KB articles to detach and reattach the databases. It appears that the SP2 installer does not work correctly if mssqlsystemresource mdf and ldf files are not in the same location.
Whilst the Engine could not be started €“ the new mssqlsystemresource.ldf file was manually moved to the %log% file, overwriting the previous version.
The SQL Server Service was now able to start without any errors.
Since the SQL Server Service has been started two major errors have become apparent:
The following error is recorded when trying to create a new maintenance plan:

Database Mail is also broken on the server. The Database Mail Log reports an €œActivation Failure€? when a test email is sent. (the email does not arrive). The SQL Log and event viewer also report the following message:
The activated proc [dbo].[sp_sysmail_activate] running on queue msdb.dbo.ExternalMailQueue output the following: 'Error executing extended stored procedure: Invalid Parameter'
Another error affects Reporting Services reports that are accessed using the SharePoint V2.0 Web parts ( rsWebparts.cab) . The date picker in the Report Viewer web part now only recognises US format dates. It is important to note that the same reports run through the Report Manager web site work correctly using DD/MM/YYYY (English-Australian ) date format for the report picker.
It is noted that the rsWebparts.cab file was not updated by SQL 2005 SP2 install. However, the behaviour of the Report Viewer web part has definitely been affected by the SP2 install.
Are the first two issues related? Are they due to the fact that mssqlsystemresource mdf and ldf files had been moved to an unexpected location prior to SP2? How can this be fixed?
Are the Reporting Services SharePoint (V2) web parts going to be updated? We are not in a position to upgrade our Portal 2003/SharePoint Servcies V2 installation at the present time.

Here is a fairly basic question in which I'd like assistance. In determining a standard for a schema, for simplicity, my thinking is that using the long data type would meet our purposes.
Are there any thoughts on mapping out where we would not need to take advantage of long vs short? I realize the space but for this particular table, space won't an issue.
Thanks!

I have a program that allows various users to login to the sql server. On the login window there is a dropdown that lists all the databases on the server and the user can select which database they wish to login to. To get the list of databases on the server I use a login created for the program we will call 'worker'. The program logs in as worker and runs "SELECT * FROM sys.databases". Before I load the login window, I check to make sure the login worker exists or has been corrupted (in case a user deletes it or changes the password, etc) and if it has been corrupted or deleted, I recreate the login using the "CREATE LOGIN worker WITH PASSWORD = '123' " function.
The problem occurs after I recreate the worker login. The login is created successfully but when the login window appears and logs in as the worker login to get a list of the databases, I get an error saying the login failed for worker. If open the login window again, everything works fine (the worker login isn't created again as it already exists). Further, if I run the same code but put a break point in the code and step through everything, it works the first time.
Is there an amount of time that is necessary to wait for the CREATE LOGIN function to be executed?

When I call this SPROC from SQL Server Management Studio, it executes in under 3 seconds. When I try to execute the same SPROC using .NET's SqlCommand object the query runs indefinitely until the CommandTimeout is reached. Why would this SPROC behave differently with the same inputs, but being called from .NET? Thanks for your help!
