hi,
im doing network monitoring app where basically i run a checks on servers every few minutes and log the data to a table. Naturally the table can get big, quite quickly. What I want is to be able to overwrite the table data at the start of each new day. Alternatively, rollup the data into a daily or weekly packets and then overwrite table data. How do i do this?
Hi,
I have a small requirement in SSIS Error Logging Mechanism.
Presently in my SSIS package i am using a File Connection Manager for creating a Log file.
I have a problem on this regard. Every time when i am executing my DTS package, the error log messages are getting appended to my error log at OS level (say D:error_messg.log). And for this reason whenever my DTS package is getting executed the size of the file is keep on increasing and there by killing my disk space.
I have a requirement for this error logging mechanism. At any time my log file should not exceed more than 20MB.
Or can we remove the log events a week ago or say more than 2 days or say. Just ensuring the log file do not fill up the disk space eventually.
How can we do this?
Any suggestions are greatly appreciated.
Thanks & Regards
It is possible to find table size and in that table each row size.

How can I restrict the number of records in a table in SQL Server 2005, please?
Thanks
Hello,I am running SQL Server 2000. I would like to know whetherMicrosoft Transact-SQL has a method for limiting the resultset from a query in a way analogous to MySQL's LIMIT keyword,so that, for instance, if the result set contains 10,000 rows,then only the first 10 rows from the record set are output.Thank you,Best Regards,Neil

Hi!,
I have a process(Peoplesoft) in SQL Server which takes long time to finish. I am looking for is there any way to find out fragmentation of the table to defagment it or is there any way to allocate the size for particular table. Couple of users are running the process at same time but as SQL Server has table/page locks it locks and releases after the job is done. Can i make it row level lock by executing sp_tableoption procedure. I would appreciate for all your suggeations.
Thanks,

I have a table like below,
CREATE TABLE Student
(
Id BIGINT not null
,Name NCHAR(20) not Null
,Branch NVARCHAR (64) null
)
The table contains : 100000 rows .
1)Number of rows in a data page
2)Total number of pages required for the table
3)Total Table size in KB or MB
4)Total file size in Kb or MB
I'm trying to understand what is happening to one large table.
In a DB SQL 2008R2, I'm trying to track a rapidly increasing DB size. It's due to one table recently added.
Despite the table's no rows increasing its size reduces after a scheduled re-index.
I've recorded the space used by this table by recording EXEC sp_spaceused 'tableName'
---
NoRows reserved data index_size unused
128864512300384 KB 2290928 KB9432 KB24 KB AFTER reindex
128864515406232 KB 5366184 KB39280 KB768 KBBEFORE reindex
N.B. The only thing I'm aware of happening in the time period is a reindex as part of scheduled task. I could be missing something else happening.
The table has only one Index the PK which is clustered, No Fill factor is specified. The Server Default fill factor =0.
I read fillfactor=0=100 Will always try and fill the pages so space used will be minimised?
After running the reindex the index fragmentation is v.low. I've not recorded the fragmentation before reindex.
I can see the Data is not added in Clustered index order.
I would like to get the size of the tables in my database BUT as follows:
SIZE OF (SELECT * FROM myTable WHERE Section = 1)
...what is the fastest way to do it?
I have a table with 99.9% of unused size. How do I reduce the size?I have tried those commands below but they do not work.
ALTER INDEX [VBDATA~0] ON qa2.VBDATA REBUILD
DBCC CLEANTABLE (QA2,"qa2.VBDATA", 0)
WITH NO_INFOMSGS;
GO
ALTER INDEX ALL ON qa2.VBDATA REBUILD

the problem is that the sum of all tables is not the same size when i make a full database backup.
example of this is when i run this query against my database i see a sum of 111,899 KB that they are 111MB,but when
i do full backup to that database the size of this full backup is 1.5GB,why is that and where this size come from?
THX
How can we monitor the all tables in all databases and send notifications to the team.Is there a way to check to find the no of rows and size of a table last month and find out growth % now

I'm trying to decide whether MS SQL will allow me to accomplish the following objectives at no cost, or whether I'd eventually have to pay for an MS SQL upgrade to accompish my objectives.
I have big, unrealistic dreams. I want to create a humorous newsblog into which I would post more than a dozen times a day. Most of the posts would have large photographs. Presumably, I'd archive the posts by subject and ranking and 'most viewed," etc., using a database.
1) Will the space limitations of the MS SQL Express edition be an issue after a while?
2) Could I hire a web developer to help me from a remote location, once the website is large enough to warrant expansion? Or does the MS SQL Express edition allow only one user? I read something I didn't understand about CPU restrictions.
3) I'm confused because web hosts advertise the availability of MS SQL databases on their server...so does that mean I wouldn't have to buy an upgrade if it became neccessary? (I know, I'm shockingly uneducated.)
4) I'm going to buy Office 2007. Is it important to purchase a package that includes Microsoft Access, given my goals?
5) Any other thoughts in plain english on how the MS SQL express edition imposes limitations....basically, I don't understand how MS SQL Express might limit me down the road if the site were actually a success. What would have to happen before I would be forced to spend a lot of money on an upgrade later?
I'm almost completely new to computing. I've read a bunch of criticisms of MS SQL Express on internet forums that I didn't understand, but that really made me worried about my decision to go with Microsoft Products and Asp.net web hosts. (I understand some people have an irrational dislike of Microsoft, but there was A LOT of bashing.)
Hi,
please do help. Have been wrestling with this for about 3 hours and read a buncha forums + searched the tutorial lists.. AARRGH!
Anyhow,
I have to paginate a datalist (and I really can't use a datagrid because of the layout, blame the bluddy graphic designer)
I want to return the top 8 rows, the next 8 top rows and so on.
This is the sql string I have:
'retrieve pagination in order to construct the rest of the sql string
Dim startrec As Integer
If pageno = 1 Then
startrec = 0
Else
startrec = (pageno - 1) * pagesize
End If
' this builds the sql string, getting ONLY the records we need for this. Page size is a constant expressed on the base page
' startrec is the record where I want to start in the db.
strsql = "select top " & pagesize & " * " & strsqlbasic & " and itemID>" & startrec & " order by itemnotes1 asc"
noresults.text = strsql & " <br> " & searchwhat & searchfor
strsqlbasic is constructed elsewhere and is just the 'from X where y = var
Of course, this returns all records where the value of itemID is greater than the value of startrec. How would I change this so it returns the next 4 rows starting from the row number given by the value of startrec?
thanks for any help.
I was wondering if there is a way to select ranges of rows, for instance:
I want rows 5-10 of a database, how would i select that?
I know in MySQL you do a "limit #,#", no clue about SQL Server.
Orcale uses a psuedo colum ROWNUM to limit the number of rows returned by a query. Does MSSQL server 6.5 provide some similar feature (or any indirect way of doing that).

I have a problem on microsoft sql server 2000.
I need to limit the amount of resources(eg cpu, mem..) a query uses
Is there a way to do this in SQL server 2000
Thks in advance
:eek:
I'm trying to write a query where if the value of one of the paramters is equal to "-1" it will not include one of the search criteria. For example I have a param called "Gender". 0 = Male and 1 = Female. If the value of the "Gender" param is "-1" I'd like it to find either Males or Females.
Code (please not this doesn't compile):
SELECT
[UserID],[Gender]
FROM
[table_user]
WHERE
Country = @Country
AND IsOnline = @IsOnline
IF (@Gender != -1)
AND Gender = @Gender
Obviously this doesn't work, but I think it conveys the gist of what I'm trying to do. Does the secret lie in default parameters? Or is my IF syntax just flat out wrong?
Thanks!
I am trying to convert some mySql code to sqlserver and was amazed to see that sqlserver has no functionality to specify the rows of a select statement. In mySql its e.g. "SELECT * FROM table LIMIT 20, 10" this returns ten rows starting from row 21. Using TOP in sqlserver only returns the top n rows but what if I want row 20 to 30? Is there an easy way that I have just missed or does one realy have to do something like "SELECT TOP 60 * FROM myTable WHERE id NOT IN (SELECT TOP 40 id FROM myTable);"?
Hope you can reply with good news...

Hello everyone.. I'm working here on a little problem which's driving me nuts : I have two tables :EQUIPMENT :
-EQID
-EQName
-EQblabla QUALITYCHECK :
-QCID
-EQID <---- Is connected with EQUIPMENT
-QCDATE
-QCACTION
-QCnextdate They're needed to manage Qualityactions on some machines we own. Every year, we do quality actions on every machine, after then, we Inserta new QUALITYCHECK-entry into our database and automatically theQCnextdate is generated with QCdate+365days. So far, so easy. So now, how will i do a query against the DB with the NEWEST QUALITYCHECK-entrys for every machine ? The result has to besmth. like that : EQID | EQName | QCDATE | QCNextdate
1 | machine 1 | 21.12.2006 | 21.12.2007
2 | machine 2 | 21.06.2006 | 21.06.2007

4 | machine 4 | 21.12.2005 | 21.12.2006
5 | machine 5 | 23.10.2006 | 23.10.2007
AND NOT
EQID | EQName | QCDATE | QCNextdate
1 | machine 1 | 21.12.2006 | 21.12.2007
1 | machine 1 | 21.12.2005 | 21.12.2006

2 | machine 2 | 21.06.2003 | 21.06.2004etc..
I tried several things with top 1, subquerys, distinct etc..But unfortunatly it seems that im not capable to solve the problem..I would be thankful for any suggestions !

It's not working correctlly. Any ideas?

Hello,
We are migrating from VB6/MySQL to VB6/MS SQL.
The application retrieves limited records for paginated results.
This way we can access large databases, but only return rows for one screen.
For example:
Select row 1 - 10, then 11 - 20 then 21 to 30 etc.
With MySQL we can use LIMIT and OFFSET and it works great.
MySQL
SELECT <columns> FROM <tables> [WHERE <condition>] [ORDER BY <columns>]
[LIMIT [offset,]howmany>]
Does anybody know how we can do something similar with MS SQL?
Any feedback is appreciated!
Thank you,
Edi
I know how to do this in MySQL; but I was hoping there was a way to do it in MS SQL.
I want to be able to limit the number of rows an UPDATE or DELETE will effect regardless of the WHERE clause. I want to do this as a stop gap in the event that there is a logical error in the WHERE clause that would make it effect more rows than is humanly intended.
If I write a complex query that I know should drill down to only affecting one row, I just want to lock it in before I run it on database and take the risk of damaging some data.
In MySQL you would just do something like this:
Code:
DELETE FROM table_name WHERE ... LIMIT 1;
The only thing close to LIMIT I could come up with for MS SQL was TOP but it seems to only work for SELECT.
Any ideas would be greatly appreciated.
I ask this because if you screw up; manually saving 1, 2 or even 5 rows is a lot easier than having to rescue a whole table of data (even if it on a development server).
I have a table that looks like
CP | P | ST | Date
where each letter represents a column. I need a SELECT statement that results one row if there is an entry with a date within the last 6 mo for each CP,P,ST combination.
example:
cp1, p1, st1, 1/1/6
cp1, p1, st1, 4/1/6
cp1, p2, st1, 3/1/6
would return just the first and third row...
thanks.
any ideas?
Let me start off with my table layouts.
CREATE TABLE [dbo].[Competition] (
[Id] INT IDENTITY (1, 1) NOT NULL,
[Name] NVARCHAR (150) NOT NULL,
[Remarks] NVARCHAR (350) NULL,
[Start] DATETIME NOT NULL,
[IsActive] BIT NULL,
[End] DATETIME NOT NULL,
[Code] ....
Then here is my query with the problem below. The problem is that multiple EntryImages can relate to a single Entry. My goal is to only select one Row for each Entry (using @EntrySelection) but when I join to EntryImages I always get back multiple rows when an Entry has multiple EntryImages.
Declare@EntrySelection int= 10
select top (@EntrySelection)
[dbo].Entries.Id,
[dbo].Entries.CatchDate,
[dbo].Entries.CompetitionId,
[dbo].Competition.Name,
[Code] ....
We currently have a routine that "forks" out (to use the unix term)TSQLcommands to run asynchronously via SQL Agent jobs. Each TSQL commandgets its own Job, and the job starts immediately after creation.Sometimes we can have too many of these jobs running at the same, andthe box crawls to a slow speed until the jobs finish up.Is there a way we can limit the number of active jobs running under theSQL Agent at one time? Or is there away to limit the number of active(runnable) processes on SQL Server, in general?
