I'm tryin to copy information from a fact table from one server to another server but when try using a DTS package to do this, an error pops up that says "the Filegroup <filegroup_name> has no files assigned to it."
what am i missing here?
Problem: I need to build several databases on a quarterly basis. The databases range in size from 30 GB to 250 GB. I want to keep each dtabase file <= 20 GB so my databases contain from 2 to 13 database files (I put these all in one filegroup. the filegroup is separate from the PRIMARY filegroup which contains only the system tables in my databases).
I would like to create the files for the databases asynchronously (I have four physical drive letters on which to create the files and would like to be building one file on each drive simultaneosly). I can acheive the asynchronous operation by creating a separate job for each of the drive letters and then callin sp_start_job for each of the jobs.
The problem is that the ALTER DATABASE command apparently locks the sysfiles table and three of the four processes are always blocked and I therfore end up build the files serially instaed of in parallel.
Is there a way to make these processes work in parallel?
Due to SQL's proportional fill algorithm I'd like to have the amount of data in my data files as close to equal as possible.
File sizes before:
dat 482,895 MB 0% free
2dat 436,927 MB 3% free
I made the max size of each file 600,000 MB and added a third file 3dat also 600,000 MB. I rebuilt all the clustered indexes (and nonclustered for good measure) and unfortunately the re-balancing wasn't quite right.
File sizes after:
dat 464,761 MB 77% free
2dat 443,234 MB 73% free
3dat 309,568 MB 51% free
I only have a handful of heap tables that take up <100MB total so they're not the issue. I did do an ONLINE index rebuild. I'm not sure if an offline rebuild would have been better. I will not be able to try and offline for a few weeks though as it's time consuming and I have other tasks I need to run on this test server now.
I did a FULLSCAN rebuild on any column statistics not updated by the index rebuild but that didn't help either.
I read , When sql server Database having multiple data files within single filegroup then sql server writes data in multiple proportional file algorithm where the amount of data written to a file is proportionate to the amount of free space in that file, compared to other files in the filegroup.
so if there is no filegroups created and multiple secondary files are attached in databse , is there same way data stored and writes data in multiple files by the same algorithm or any different way.
I am moving some code that was created in visual studio 2002 into Visual Web Developer 2005 express edition and am getting a warning on some of my code before compilation.
The warning is "Variable lSqlTransaction is used before it has been assigned a value. A null reference exception could result at runtime". I experienced no problems in vs2002.
The offending line is the rollback command within the exception. If I move it out of the exception it no longer flags the warning, if I move it after the throw statement it now longer flags the warning. Any help appreciated.
Heres the code
Public Shared Sub ExecuteNonQuery(ByVal lSQLCommand As SqlCommand)
Dim lSQLConnection As New SqlConnection(SQLConnString(enmSQLDB.enmSQLDB_TPSDB))
Dim lSQLTransaction As SqlTransaction
Try
'-----------------------------------------------------

Greetings,
We have a standard audit trigger on one of our tables. The trigger type is "after insert, update". The trigger populates four table columns, telling us the login and time the row was created and last updated.
We use replication to synchronize three servers. The trigger specifies "not for replication" on all servers.
The code used to grab the identity and time of the last update is shown below.
LastEditedDate = GETUTCDATE(),
LastEditedBy = SUSER_SNAME()
What I observe is that the LastEditedBy value is sometimes different for the same row on different servers even though the time value is identical. I don't know how to explain this. It looks like the login value is being recalculated during replication while the edit time is not.
For the record, the correct login will be something like "MYDOMjoe" while the incorrect value on another server will read "NT AUTHORITYNETWORK SERVICE". Do these symptoms ring a bell with anyone?
Thanks,
BCB
I have a problem with datatype mismatches. In my Data Flow I am reading a Flat File that includes a DateOfBirth which SSIS correctly assigns a datatype of [DT_DATE]. I need to check to see if the record has previously been submitted, so I do a Lookup that uses a SQL statement that combines fields (LastName, Zip & BirthDate) from three different tables. My problem is that SSIS assigns a datatype of [DT_DBTIMESTAMP] to BirthDate, which I can't use because of the mismatch. I have tried every form of re-formating the field in SQL that I can think of, but it still gets assigned that DT. And I'm unaware of a way of changing the DT once SSIS assigns it in the Lookup task.
Help!...very frustrated,
Dave
I need to update a table using a stored procedure that "UPSERTS". In this case, @OfficeId is passed with ParameterDirection.OutputSo when I update I assign the value to OfficeId like this (the office id value is being correctly assigned): SqlParameter OfficeIdParam = new SqlParameter("@OfficeId", SqlDbType.Int, 4); if (_officeId > 0) { OfficeIdParam.Value = _officeId; } OfficeIdParam.Direction = ParameterDirection.Output; The following segment of the stored procedure is throwing an error that the OfficeId does not exist: Update --- @OfficeId int output if not exists (select 1 from ORG_Office where OfficeId=@OfficeId) begin RAISERROR ('OfficeId does not exist in ORG_Office: E002', 16, 1) -- OfficeId does not exist. return -1 end May this approach work, and if the operation turns out to be an Insert I may do this:select @error_code = @@ERROR, @OfficeId= scope_identity() Thank you,jspurlin

Is there a way to assign multiple variables to one select statement as in the following example?
DECLARE @FirstName VARCHAR(100)
DECLARE @MiddleName VARCHAR(100)
DECLARE @LastName VARCHAR(100)
@FirstName, @MiddleName, @LastName = SELECT FirstName, MiddleName, LastName FROM USERS WHERE username='UniqueUserName'
I don't like having to use one select statement for each variable I need to pull from a query. This is in reference to a stored procedure.
Thank you!

I have a report where certain columns have values that get repeated, but the client has a rigid requirement for not wanting these columns as groups in the reports (other programs and exports doing specific tasks with those values). In these reports, the "hide duplicates" value is checked, so as to give an aesthetic sense of grouping.
The data for the report, in raw form is:
Value 1
A
Value 1
B
Value 1
C
Value 2
D
Value 2
E
Value 2
F
Value 3
G
Value 3
Hetc...
In its aesthetic form, it is:
Value 1
A
B
C
Value 2
D
E
F
Value 3
G
H
My question is, how can I use RunningValue() to give me the following row numbers based upon those repeated values acting as grouping, since I'm not using formal grouping in the report design?
Value 1
1
A
2
B
3
C
Value 2
1
D
2
E
3
F
Value 3
1
G
2
H
Thanks for any input!
Hello all,
This seems like a simple question but I still haven't been able to get an answer from Microsoft Canada. We're looking at buying 75 device cals to connect to a single instance of SQL Server Standard Edition. Our question is on how those licenses are assigned and/or activated.
Do we need to manually do something for each station or is it an automated process done the first time a station connects to the server? We also wat to understand what happens when a workstation dies and is replaced by another one. Do you have to do something on the server to transfer the license to the new station ?
In other words, when using device cals (and/or user cals), do you have to do any type of license management or is it all transparent ?
At our site, we page DBAs whenever an alert with a severity of 20 or greater is raised. This never was an issue until SQL Server 2005. Now every SSPI error is paged since it is a severity 20. I don't believe the errors are severe enough to qualify an assignment of 20. Anybody else have any thoughts on this?
Thanks.
Hi,
In SQL Server Express Edition, what are the rights that are assigned to a Normal Windows User and PowerUser by default ?
When I install SQL Express on a clean machine and login as Power User I can add/edit/delete data but when I login as Normal Windows User I can see the data but not change it.
Please help me in this regard.
We have SELECT INTO queries that use the IDENTITY function to assign a sequential row number to a result set based upon a sort order. This has been helpful in SQL Server 2000 for median determination. It appears, however, that in SQL Server 2005, the row numbers are not assigned sequentially, or maybe they are assigned before the sort order is applied.
Can anyone verify whether the IDENTITY function has changed behavior between 2000 and 2005? We would prefer not to have to make changes to existing queries. Thank you.
(BTW, the workaround we found so far is to put the initial SELECT...ORDER BY in a subquery, but then we had to include a phrase like TOP 10000000 to pass syntax check. Is there a better way?)
I restored a sql server database today. There is a problem though. In SQL server, right next to the name of the database are the words "Restricted User". Their seem to be some limitations on my access to this database now as I am not able to run some of my C# code against the database. How can I fix this in SQL server so that I am not a Restriced user.
Example of what I am talking about. In SQL server my database is named Gorlaz. Just to the left of this is a yellow Icon that represents the database "Gorlaz". For illustration purposes I will use the character "$" to substitute for the yellow database icon. So this is how it reads in SQL server management studio.
$Gorlaz(Restricted User)
Can anyone help me with this? The objective is to allow an application user (with db_datareader & db_datawriter database roles assigned) to be able to create tables in the assigned schema (dbo) via a new role.
-- Create User
use master
go
create login DBA with password='xx', CHECK_EXPIRATION=ON, CHECK_POLICY=ON
use AdventureWorks
go
create user dba from login DBA
alter user dba with DEFAULT_SCHEMA=dbo
go
-- Create Role
use AdventureWorks
go
create role sp_ddl_role AUTHORIZATION dbo
grant CREATE TABLE to sp_ddl_role
-- assign user to Role
use AdventureWorks
go
exec sp_addrolemember sp_ddl_role, dba
go
-- Create Table statement then run with following error
Error:
Msg 2760, Level 16, State 1, Line 1
The specified schema name "dbo" either does not exist or you do not have permission to use it.
Remedy: Grant ALTER on schema::dbo to sp_ddl_role
My problem is that I want to restrict user permissions via this role to just the CREATE TABLE and granting ALTER on a SCHEMA will open up a whole lot more permissions from a security standpoint.
Question: How do I restirct this role to just the CREATE TABLE within a SCHEMA?
Hello (help),
In SQL2000, when the Guest account was assigned into a role, such as db_datareader, then querying across databases worked just fine.
Specifically:
I have a Report Writer application that connects to the SQL Server with a login (ReportRunner) that actually has very limited permissions on a database.
The connection is then set (sp_setapprole) to use an Application role (App_RR) that has the necessary permissions.
The report-writer app calls a Stored Procedure that gathers data from several other databases (on the same SQL instance).
In SQL 2000, accessing these other databases was done through Guest - we assigned Guest to the db_datareader role. All worked fine.
We've just upgraded to SQL2005: reports started failing. It seems that although guest is assigned to the db_datareader role, the permissions for Guest don't allow selecting from tables via the db_datareader role: we've had to GRANT SELECT TO Guest specifically on the tables necessary for the report.
Is anyone aware of a design change withing SQL Server such that the Guest principal's roles are disregarded when assessing permission? Is there a new and better way to structure the permissions?
Thanks in advance for your help.

We have been storing packages in the File System folder. We had noticed that there seemed to be times when re-importing an existing package did not seem to update it properly. We tried deleting the existing package first rather than overwriting it, but to no avail.
Today we noticed that there were two DTS90Packages folders, one on the C drive and one on the D drive. The dates on the files in those folders showed that sometimes the import put the file on one drive, and other times on the other drive.
The MsDtsSrvr.ini.xml file shows this: "<StorePath>..Packages</StorePath> ".
We intend to stored the packages in the msdb database instead in order to work around this problem.
Has anyone else noticed this happening?
Thanks,
Ron
Hi:
When I restore DB from testing to production, we want to remove extra access rights granted to public group. Is there a simple way to query to find out for which objects (table, view, sp, fn) that public group were granted select, delete, update insert, or execute rights?
My objective is to write a sp to remove all user assigned rights to public group (role), but not to deny any rights. How to do it?
Any suggestion will be appreciated.
Is
there a way to find a list of Windows User accounts that are directly
or indirectly (through Windows Group membership) assigned to a database
role?
I could put work in to CLR programming or using a Linked Server to
Active Directory, but if there is a sys.* view available that can
provide me this
information directly it would be much easier.
I'll be looking into this further myself anyway and posting an answer
if I can find one, but if anyone has suggestions... well, thanks!
Hi,
I have a script component. What it does, it queries the a table using a connectionstring assigned to it in the Connection Managers Editor (which is an ado.net adapter). this works fine when i'm using a windows login in the ado.net connection manager. But when i changed my connection to use SQL server login, I encounter this error:

hello,
ihave atablelike this -
z uniqueidentifier
a varchar(40)
b varchar(40)
c varchar(40)
d varchar(40)
e varchar(40)
f text
g image
I am asked to split this table into 2 filegroups and move text and images on to one and other stuff on one.
I am new to MS-SQL 7.0.
Can anyone suggest me how to go for it.
Thanking you.
i understand that the filegroup for a table can be specified in the CREATE Table statement. just out of curiosity, is there any way to move a table to a different filegroup, that too, if the table contains data.
View 2 Replies View RelatedHi,
There is a table which is about 50GB is size.
I am thinking of placing the database of this table into a separate .ndf on a separate drive on the server.
Is it possible to place this particular table into a searate drive to increase the performance even more?
Basically my question is: is it possible to place tables into separate .ndf files?
Thanks
Hi,
I have created a database with two filegroups called FG_GroupData, FG_GroupHistory.
FG_GroupData is set as default.
FG_GroupData contains two secondary data files i.e. GroupData1.ndf and GroupData2.ndf
I can create a table so that it is stored in FG_GroupHistory. i.e.
CREATE TABLE dbo.OrdersHistory
(
OrderID int NOT NULL,
ProductID int NOT NULL,
CustomerID int NOT NULL,
UnitPrice money NOT NULL,
OrderQty smallint NOT NULL
)
ON FG_GroupHistory
Questions:
1)
How do I add tables to each .ndf file inside a group i.e. FG_GroupData
For example, how do I add a table to GroupData1.ndf and one to GroupData2.ndf ?
2)
I guess there is no need to place the file name i.e. .ndf inside the select query
Thanks
What is the advantage of having two secondary files inside a filegroup.
For example, I can create a table and place it inside a filegroup which obviously will use the secondary files.
Not sure why some DBAs create just one but otherscreate more than one secondar files in a filegroup.
I have read the booksonline but can not figure out the advantages.
Thanks
Can anyone show me in SQL7 how to obtain Available Space on a particular filegroup in a database (not the database or datafile).
I am trying to include this in a script to monitor my database which uses Filegroups and I have every other info that I need (from the sysfiles table) except the available space. Thanks in advance!
hi...
I don't know well this statement...
1. from Transcender
.....
One file for each filegroup is sufficient because creating multiple files for the same filegroup on the same disk does not provide any performance gain
2. from bol
....
Therefore, creating more files per filegroup can help increase performance because a separate thread is used to scan each file in parallel
what is correct ?
thanks !!
Hi ,
I am restoring a VLDB from a Standby server which has just .mdf and .ldf to my production server which has .mdf and a file group with a single .ndf

Any hhelp will be greatly appreciated..

Is it possible to back up one filegroup independently from the second when tables
in one group have foreign key relationships with tables in the second group?
I want to remove a filegroup.
ALTER DATABASE MyDBName
REMOVE FILEGROUP MyFileGroupName
It says:
Server: Msg 5042, Level 16, State 7, Line 1
The filegroup 'MyFileGroupName' cannot be removed because it is not empty.
Question: How can I tell what is on this filegroup.
<Forgive me if it is a simple BOL answer, but I'm having trouble finding it>
Hello,
A few days ago one our database's default filegroup filled up. To solve the problem one of my colleagues created a new filegroup. This didn't solve the problem as no objects were placed on this filegroup and the initial one is still full. The idea was to expand the original filegroup over a new physical disk, not to create a new filegroup on that disk. Unfortunately, this is what happened.
To solve this I want to delete the new filegroup, but when I issue the command 'alter database PvgOmcsOds remove filegroup ternary' I get the message 'Server: Msg 5042, Level 16, State 7, Line 1 The filegroup 'ternary' cannot be removed because it is not empty.' Yet there're no objects placed on this filegroup.
How can I get rid of this filegroup?

I am managing 120 gb SQL7 database. The 120 GB is in a RAID5 (Hardware RAID). At begining, I think I should create a user defined filegroup besides Primary filegroup, as BOL suggested.
After I read some discussions here, It appears I cannot gain any performance by adding second filegroups. Now I want to drop the filegroup I created. The Question is How?. If I do alter database, move all files from userdefined filegroup, does this mean my userdefined filegroup has gone?
Someone can help me on this!
Thanks a lot.
