Splitting Datafiles
Jan 13, 2004
I founded couple thread about splitting but not find same situation what i have.
I have server with Raid10 with big storage massive, and Test server with two 30Gb HardDrives (not into a Raid or Somethink). I have situation when in real server database grown over 30Gb and now i can not restore database copy into a test server because i have one big Data File.
Can i split somehow 35Gb Data file when i restore to test server to 25Gb and 10Gb ???
Or can u recomend some solutions
At the moment cant to do hardware upgrate.

Hi,
I have a datadabase with 1 datafile from 60Gb. Is it a good thing(preformance) to split up this datafile in smaller datafiles from 6Gb each?
I don't have separete diskslices so a can't spread my datafiles on my disks but i only need to know if a datafile from 60Gb sin't too big for MSSQL2000.
Thanks,

Good morning,
When I install a database I set up datafiles to another volume with greater capacity. I would like to know about the report service, there is need for datafiles be placed in another volume, or it may be placed in the same volume of the operating system?
Thank you,
Best Regards,

Hi,
I need to set up a Standby database using a copy of datafiles of the primery database. (An SQL backup of the database is not an option).
Is there any option to restore a database from datafiles?
Or is there an option to attach database but into an standby mode?
Please advice,

Hello,I am trying to clean up a database I inherited.I have an 80GB SQL 2000 database with 20 datafiles each 4096 in size. Ihave been able to remove unneeded data and am now trying to clean up.If I do a Shrink on each datafile would able to recover on average 2gbout of 4g, however I would prefer to have 10 full datafiles and 10empty. (or better yet 5 full 8GB datafiles and 15 empty)Can someone point me in the right direction on how to move the dataaround so that dont have 20 partially filled datafiles?I have noticed that I can shrink a single file and use the "empty thefile option (and move data to other files in the group)." option. Ihave already done this to the last 2 datafiles as a test but not surehow to do this on a large scale. I have also set the 1st 10 datafilesto be able to grow to 8 GB.For lack of a better way to say this, Is there a way to defrag orreorganize the data ables so everything "moves to the front".BTW, I have already run a maintenance plan to reorganize the data andindex pages.

I had asked a question last week and I realized that I had phrased it in a misleading way. Within a lab environment at my company, we are experimenting w/ accessing remote SQL data files stored separately on another machine from the SQL server itself (whether it be another client or server).
The experiment is this: You have one client machine accessing a SQL server via Enterprise Manager. The datafiles that you are trying to access are stored on another machine that does not have SQL Server installed. This remote machine only has the datafiles.
Can one map a static path via UNC from the SQL server to the datafiles on the remote machine and then access these datafiles (as long as the user's account has the appropriate permissions to the remote machine)? To my understanding, within SQL server you can only access datafiles that are stored locally on the SQL server itself.
The other thing that I was wondering was if the type of user account had some significance in this situation. More than likely, a local user account would not be able to access the remote machine w/ the datafiles even if the SQL server could map an UNC path and retain it. A domainuser account might be able to do this though.
Any help that you could provide would be appreciated.

I have a sql2005 db. I'm trying to perform a query that takes a list of values in a parm, breaks them up and uses them in an IN clause as follows:
<code>
ALTER PROCEDURE [dbo].[SelectPartialOrderListByDate] @StoreID varchar(255)ASBEGIN SET NOCOUNT ON; SELECT DISTINCT O.OrderID, M.InitialSalesCode, M.DateOccurred, M.ErrorCode FROM dbo.OrderInfo O WITH (NOLOCK) INNER JOIN dbo.Message M WITH (NOLOCK) ON O.OrderID = M.OrderID WHERE O.StoreID IN (@StoreID)END
</code>
The values coming into the procedure are obviously in a varchar string format.
Notice the boldfacing above. The values within this IN clause should be something like this after the conversion: IN (87,108).
How can I accomplish this? I've seen examples of creating a UDF and returning a table, but am not sure how to apply that to my situation via a code sample.
Could someone help me out?

I have a table that contains agrrements and contracts with dates. Now I need to calculate some things and I'd like the rows to only have one month per row.
I have rows like:
Agreement, Start, End
ID001, 2004-01-01, 2004-04-30
If I could get these single rows that contains 4 months into a temptable like this:
Agreement, Start, End
ID001, 2004-01-01, 2004-01-31
ID001, 2004-02-01, 2004-02-29
ID001, 2004-03-01, 2004-03-31
ID001, 2004-04-01, 2004-04-30
It would simplify my calculations very much. How to do this with a query or sp?

I everyone, I have been on the admin side of IT for the past 20 years and recently started to do some scripting (VBscript) and a little SQL.
I have developed a solution to meet the needs of some federal auditors, but not really met my needs yet.
What I have done is this.
I use MS Logparser to go out to 64 servers and copy the event logs into a DB on a SQL 2000 Ent. Server.
On the SQL server I have one StoredProcedure that parses out information from the security event log DB and put that info into a temp DB.
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[stp_SecurityAuditReport]
AS
TRUNCATE TABLE SecurityEvents_Tmp
-- Parse Bank Number & UserName
INSERT INTO SecurityEvents_Tmp(DepartmentNumber, UserName, EventLog, RecordNumber, TimeGenerated, TimeWritten, EventID, EventType, EventTypeName, EventCategory, EventCategoryName, SourceName, Strings, ComputerName, SID, Message, Data)
SELECT
DepartmentNumber = '001',
UserName = CASE
WHEN Strings LIKE '[0-9][0-9][0-9]%'
THEN SUBSTRING(Strings,1,charindex('|',Strings,1)-1)
WHEN Strings LIKE '-|[0-9][0-9][0-9]%'
THEN SUBSTRING(Strings,3,charindex('|',Strings,3)-3)
WHEN Strings LIKE '-|[a-z]%'
THEN SUBSTRING(Strings,3,charindex('|',Strings,3)-3)
WHEN Strings LIKE 'Account Unlocked. |%'
THEN SUBSTRING(Strings,21,charindex('|',Strings,21)-21)
ELSE SUBSTRING(Strings,1,charindex('|',Strings,1)-1)
END,
Events.*
FROM Events
JOIN EventsToLog on Events.EventID = EventsToLog.EventID
WHERE SID NOT LIKE 'S-%'
-- Update blank usernames
UPDATE SecurityEvents_Tmp SET UserName = 'NO USERNAME'
WHERE UserName = '' OR UserName = '-'
-- Update DepartmentNumbers with zeros
UPDATE SecurityEvents_Tmp SET
DepartmentNumber = CASE
WHEN UserName LIKE '[0-9][0-9][0-9][a-z]%' OR
UserName LIKE '[0-9][0-9][0-9]#%' OR
UserName LIKE '[0-9][0-9][0-9]$%'
THEN SUBSTRING(UserName,1,3)
ELSE '001' END
As you can see, we use 3 didgit numeric prefixes on all Departmental employee accounts. This is later used to produce departmenntal user audit reports.
I then have this script in a DTS that exports the report to an excel spreadsheet. (All works well for this purpose!)
DECLARE @TimeGenerated datetime
SELECT @TimeGenerated = TimeGenerated FROM SecurityEvents_TimeGenerated
DECLARE @TimeGeneratedEnd datetime
SELECT @TimeGeneratedEnd = TimeGeneratedEnd FROM SecurityEvents_TimeGenerated
SELECT DepartmentName = CASE WHEN b.DepartmentName IS NULL
THEN 'All Department' ELSE b.DepartmentName END,
a.EventID,d.EventDescription,a.UserName, a.TimeGenerated,c.Email1,c.Email2,c.Email3,c.Email4
FROM SecurityEvents_Tmp a
LEFT JOIN DepartmentList b on a.DepartmentNumber = b.DepartmentNumber
LEFT JOIN EmailToList c on b.DepartmentNumber = c.DepartmentNumber
JOIN EventsToLog d on a.EventID = d.EventID
WHERE b.Departmentnumber in (select Departmentnumber from Departmentlist)
AND a.TimeGenerated BETWEEN @TimeGenerated AND @TimeGeneratedEnd
ORDER BY b.DepartmentNumber,a.EventID,a.TimeGenerated
This combination of utils and scripts does very good for producing generic security reports for branch officers.
But now I am getting requests to justify/explain what is in these reports. The problem I have is that the information needed to delve further into the event logs is in a field called Strings. This field not only changes in length and the amount of fields within this string, but the information in this field changes depending on the type of event record it came from.
This is the Strings field from a failed logon (529)
200jenil|DOMAIN|10|User32 |Negotiate|SERVER|SERVER$|DOMAIN|(0x0,0x3E7)|6920|-|10.190.12.10|48397
And this is from Event ID 642 which was an account being created.
-|381$cmiller|DOMAIN|%{S-1-5-21-3554868564-134719009-1577582102-7972}|Jmotta|DOMAIN|(0x0,0x58F635E)|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|%%1792|-|-
Now, my script does a good job of getting the first user name out but as in the 642 event the second users name would be useful as well. This is the person that created/modified the user account.
So what I was hoping was that I could use a function (or whatever) to automaticaly split the Strings value into it's individual components and put them into an auto-sizing temp table as something like Field1, Field2, Field3, and so on until the end of string.
I could then use a case to get the information needed.
HELP PLEASE!!
Thank You,
John Fuhrman

I have a large db (sql 2005 express) that is, well, basically a mess. It is not normalized properly and contains masses amount of data (due to so much repeating data). To make a long story short - this db needs to be redesigned, but management said no, so that is not an option - so please, no one suggest that that's what I do.
My application creates reports based on this db - the problem is, the sp's are slow - and when a report needs to run several reports, it takes a long time to run. The sp's and db have been optimized as best I can (adding indexes etc.,)
I was wondering if there is a way to split the db - what I want to do is just retain, say 2 years of data in 1 db, and store the rest of the data in the other db, as 2 years worth of data is 95% of what will be queried. I did copy over 2 years worth for testing, and reports that took 30 minutes in the existing db, take less than 1 minute (sometimes even faster) in the new db - a huge improvement.
My problem is how to deal with the times that I need more than 2 years worth of data - how do I query both db's to get my application to read the data from both db's so that it seems that I am only running one db? The new db would be updated daily with new data, but not the old db - so if I had to query 10 years worth of data, I need 2 years from the first db, and then the 8 yeas from the second db.
If anyone can provide some feedback or point me in the right direction of what I should research in order to accomplish the above - I would appreciate it.
If anyone knows of a better solution - please don't be shy - speak up! :)
Thanks - ann

Hello,I have been placed in charge of migrating an old access based databaseover to sql server 7.0. So far, I have imported all the tables intosql server, but now I have come across the issue of needing to split astring variable. For instance, in the old database, the variable forname was such that it included both first and last names, whereas inthe new database there are seperate entities for first and last name.I know that there is a way to write a script that will separate out thetwo strings by using the "space" in between the name, but I'munfamiliar how to do this. Any suggestions? Thanks!Rick

One of the fields has data seperated by a comma. I need to be able to grap the data for each record and split those items into their own table in seperate rows. This is easy in Asp but the page will timeout before it can process all the records.
Any Ideas?

I'm trying to split a hyphen-delimited string into three columns in a view. I've been using substring and len to split up the string, but it is getting very complicated (and isn't working in all cases). I've used a SPLIT function in vbscript - does t-sql have anything similar? I've attached a spreadsheet that shows what I am looking for. Maybe someone can guide me in the right direction?
