How To Limit The Records..?
Jun 5, 2007
Hi,
I am working on building SSIS Packages which will need to extract records from OLTP Servers, and i am half way through building the package, i wanted to test if it is able to extract the records from a particular table on OLTP....basicall i want to test if the package built so far running good?....but the extraction part takes ages as there are millions of records in the OLTP ...i want to limit those records to say some thousands so that i can test it and work on cleaning part in the staging and later after all the chunks are working perfectly i want to set it completely to run for extracting all the millions of records.
Any suggestion would be appreciated.
thanks
ravi
Nothing much that i can do..!!

How do you limit the number of records returned in a recordset? I only want the 10 most recent and I've got a Date column in my database.

How could I go about doing the following:
I have a column with lets say
AHA1
AHA2
AHA3
AHE1
AHE2
ARL1
ARL2
How could I make a column next to it that is basically the same but cuts off anything after the third letter? So this new column would look like:
AHA
AHA
AHA
AHE
AHE
ARL
ARL
Thanks!

I apologize if I'm posting this question in the wrong forum.
I have a query that exports data from an Oracle database to an Excel spreadsheet. The application that executes the query is Computer Associates Eureka Report writer. I do not have direct access to the database or any of its objects. With the data in Excel, I run a VBA macro-driven inventory report. The Excel spreadsheet row limitation is not a problem presently, however, the query exports a lot of extraneous data that I don't need. I actually export about a dozen columns of data however I'm only listing 4 in the example below.
Example:
CaseNum ActionDate ActionType ComplCd
1029901 09/08/2006 F 0
1029901 09/11/2006 C 0
1029901 08/18/2006 C 1
1029901 08/17/2006 F 1
1029901 08/01/2006 F 1
When the ComplCd = 1 I only want the query to export one row of data for each CaseNum. Is
there a way to code my query to accomplish this?

In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.
Query
SELECT @SQLTier1Select = 'SELECT * FROM dbo.UDV_Tier1Accounts WHERE CUSTOMER IN (SELECT CUSTOMERNUMBER FROM dbo.UDF_GetUsersCustomers(' + CAST(@UserID AS VARCHAR(4)) + '))' + @Criteria + ' AND (number IN (SELECT DISTINCT ph1.number FROM Collect2000.dbo.payhistory ph1 LEFT JOIN Collect2000.dbo.payhistory ph2 ON ph1.UID = ph2.ReverseOfUID WHERE (((ph1.batchtype = ''PU'') OR (ph1.batchtype = ''PC'')) AND ph2.ReverseOfUID IS NULL)) OR code IN (SELECT DISTINCT StatusID FROM tbl_APR_Statuses WHERE SearchCategoryPaidPaymentsT1 = 1))'

See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.

I have a situation where deleting old records is blocking updating latest records on highly transactional table and getting timeout errors from application.
In details, I have one table called Tran_table1 in OLTP database. This Tran_table1 is highly transactional table, it will receive data for insert/update continuously
While archiving 2 years old records from Tran_table1 into Tran_table1_archive in batches(using DELETE OUTPUT INTO clause), if there is any UPDATEs on Tran_table1,these updates are getting blocked and result is timeout errors in application.
Is there any SQL Server hints to avoid blocking ..

HI,
I have been trying to solve the locking problem from past couple of days. Please help mee!!
Scenario:
--------------
I have a SSIS package in which 2 data flow tasks. 1st data flow task deletes records from a 5 tables and the 2nd data flow task should insert records into 1 of the five tables after the success of 1st data flow task. This scenario runs in Transacation.
The above scenrio in the 2nd data flow task hangs in runtime. It does not complete. with sp_who2 command i could see that there is an intent share lock(LK_M_IS) on the table and the status is SUSPENDED.
I dont know how to come out of this locking. Please help.
Thanks ,
Sunil

Hi there guys!
I was wondering if anyone know the number of rows you can import from an external source into MS SQL Server 2000 Developer Edition?
I have tried importing a whole table from another database with over a million records. But failed after 1.7 million row.
Any ideas?
Thank you!

When creating a database, SQL Server 6.5 seems to have a 2 gig limit. What I mean is that if the device chosen is over 2 gigs SQL Server displays the size of the device as anegative number. This prevents me from being able to expand the database when I need to. Can anyone tell me why this is so, and if there`s anyway around it??

Hi There
I recently read up and found an msdn forum post that said the 4gb limit only applied to data files not log files.
However recently i had an error on a sql express database saying that the log file was full, the database log file was set to auto grow and there was plenty of space left.
So i am guessing the 4gb limit applies to any database file mdf or ldf, is this correct ?
Thanx

I have a table with about half a million records, each representing a patient in my county.
Each record has a field (RRank) which basically sorts the patients as to how "unwell" they are according to a previously-applied algorithm. The most unwell patient has an RRank of 1, the next-most unwell has RRank=2 etc.
I have just deleted several hundred records (which relate to patients now deceased) from the table, thereby leaving gaps in the RRank sequence. I want to renumber the remaining recs to get rid of the gaps.
I can see what I want to accomplish by using ROW_NUMBER, thus:
SELECT ROW_NUMBER() Over (ORDER BY RRank) as RecNumber, RRank
FROM RPL
ORDER BY RRank
I see the numbers in the RecNumber column falling behind the RRank as I scan down the results
My question is: How to convert this into an UPDATE statement? I had hoped that I could do something like:
UPDATE RISC_PatientList_TEMP
SET RRank = ROW_NUMBER() Over (ORDER BY RRank);
but the system informs that window functions will only work on SELECT (which UPDATE isn't) or ORDER BY (which I can't legally add).

I have a query similar to the following. The intent of this query is to retrieve the top 6 records meeting the specified criteria (LOGTYPENAME = 'Process Status Start' OR LOGTYPENAME = 'Process Status End' ) based on most recent dates. Please keep in mind that I expect to return up to 6 records for each unique LogProcessName. This could be thousands of different LogProcessNames with up to 6 records for each.
1) The table I am executing against currently is very large in size and thus takes a long time to execute against. It would seem there must be a more efficient query to get the results I am looking for?
2) CTE doesn't work on SQL 2000. I need a query that does.
3) I cannot modify the database itself in the process.
;WITH cte AS (
SELECT [LogProcessName], [LogBody], [LogDate], [LogGUID], row_number()
OVER(PARTITION BY [LogProcessName]
ORDER BY [LogDate] DESC)
AS RN
FROM [LOGTABLE]
WHERE [LogTypeGUID] IN (
SELECT LogTypeGUID
FROM LOGTYPE
WHERE LogTypeName = 'Process Status Start'
OR LogTypeName = 'Process Status End' ) )
SELECT *
FROM cte
WHERE RN = 1 OR RN = 2 OR RN = 3 OR RN = 4 OR RN = 5 OR RN = 6
ORDER BY [LogProcessName] DESC, [LogDate] DESC
Does anybody else have any idea that would yield the results that I am looking for and take into account items 1-3 above?
Thanks in advance.

hi,i have a union statement that works like a charm:SELECT
[Name],
[EventID] AS [ItemID],
[TourID],
[Date],
NULL AS [StartDate],
[Date] AS [SortDate],
[Type] FROM [Events]
WHERE
[TourID] IS NULL
AND
AccessLevel <= @AuthenticationLevel
UNION
SELECT
[Name],
[TourID] AS [ItemID],
[TourID],
NULL AS [Date],
[StartDate],
[StartDate] AS [SortDate],
'2' AS [Type]
FROM
[Tours]
WHERE
AccessLevel <= @AuthenticationLevel
ORDER BY
[SortDate] this statement selects all the records i want from both tables, and orders the entire new table by sort date.what i want to do is to add a limitation on the number of records. i have tried using both LIMIT and TOP commands, but i can't get it working. both of the below statements give me a syntax error saying "Incorrect syntax near the keyword 'ORDER'"first try:SELECT * FROM (<same_statement_as_above>) ORDER BY [SortDate] LIMIT 2second try:SELECT TOP 2 * FROM (<same_statement_as_above>) ORDER BY [SortDate]what am i doing wrong, and how do i achieve what i want?i am working with mssql server 2005 (express locally, and standard on my hosting service). thanks for your help!

Hi,
I have an application with a DAL that has an interface with SQL Server.
The application has 400 users that open the web forms.
My question is:
Is there a limit of the parallel connections that can be opened? Or the IIS is managing all the access to the DB? Should I worry about the performance Or it's normal behaviour for ASP.NET applications?
Thanks

SQL takes all CPU resource on some of the intensive
queries. Is any way to make sure there is something left for other tasks
to be processed? Let's say limit SQL to use no more than 80% of CPU.

select top 20 * from t
where pkc not in (select top 10 pkc from t order by pkc) order by pkc
to simulate the limit function in mysql.
i want to replace the 10 in the inner select with a variable. When I do this:
select top 20 * from t
where pkc not in (select top @counter pkc from t order by pkc) order by pkc
it gives me in an error in sproc. Pls help!!

There is at present (as we accidently found) limitation of MSSQL to return per row maximally 8060 bytes. Message like this comes: "Cannot create a row of size 8279 which is greater than the allowable maximum of 8060".
My questions are :
- Is there any way how to pass it? If I split into more tables (as I have it now) and ask for result where these tables are connected over any ID the result is the same. If I use stored procedures it seems to be ok. Any other idea?
- Will be this ok in SQL server 2005?

I have an application that uses a small SQL Server database.
What I need is to prevent the access of an amount of users to the database.
At the beginning I want to limit the access only for 2 users but I want to be able in the future to grant the access to more.

MySQL has a convenient syntax for paging data that looks like this:
SELECT * FROM MyTable LIMIT 10, 20
That would select 10 records, starting from record 20, so that it returns records 20 - 30. This is convenient way to page data, without returning anymore rows than than you need.
However, MS SQL doesn't appear to support that syntax. What is the equivalent sql code to select any N rows from an arbitrary starting point, without having to create a stored procedure?
Thanks in advance :)

Quick question, is there a record limit in MSSQL assuming that we don't use a identity key. I am going to be using a table to sava mail server logs. It will create about 5000 records a minute. Also are there any perfomrance issues once you reach a certain numberof records, assuiming i am indexing one of the columns.

I have a extremely large table and out of that I just need 2 records but based on some logic . For example
IF EMPLOYEE_ADDRESS <> NULL
set Employee_HAS_HOME to 1
ELSE
set Employee_HAS_HOME to 0
Here I can not use just first 1000 records as I am not sure If I will cover the second condition in first 1000 rows . Then I came up with solution like : -
select * from employee_table where employee_address <> NULL LIMIT 1
UNION
select * from employee_table where employee_address = NULL LIMIT 1
And this will give me 2 records which I can use for my testing . But unfortunately this is not working.
