Hi,
I am trying to import some 35-40 flat files into my SQL Database, however I don't want to imort all the data from each file, but just top 20 rows only for data quality check. Flat files are very huge so I don't want to import all of the data into my database.
Thanks,

I am running a package in which all tasks participate in a transaction. One task is a ForEach Loop container that executes 1 SQL INSERT statement per loop. The Loop runs well over 100 times in order to normalize a very, very, very wide table.
It seems that at a certain point, the Loop task will fail. I've tested a few different scenarios and they all fail at the same point... the 98th loop.
The error message is below:
[Execute SQL Task] Error: Failed to acquire connection "ADO.NET Connection". Connection may not be configured correctly or you may not have the right permissions on this connection.
I'm guessing that there is a limit to the number of connections that can be started at any one time. But I figured SSIS wouldn't start a new connection for every SQL command.
Any insight on this issue? Anyone have an idea for a work around?
I have a package with an input column that is varchar(8000).
I want to strip the first byte off of this column and put it in one result column and the remainder of the field I want to go to a second column. If the input column is an empty string, I want to return NULL.
Pulling the first byte off works fine, no issues, however putting the remainder of the input column into an output column is giving me a little trouble.
If I use this expression:
LEN(FLD1) == 0 ? NULL(DT_WSTR,1) : SUBSTRING(FLD1, 2, LEN(FLD1) - 1))
I get an error that says my expression evaluates to a string of greater than 4000 bytes.
If I do this instead:
LEN(FLD1) == 0 ? NULL(DT_WSTR,1) : RTRIM(SUBSTRING(FLD1, 2, 7999))
The expression passes muster but I get the warning that I will be truncating the column at 4000 bytes.
In actuality, I don't care if the result column is truncated after 4000 bytes. I find the second solution to be a bit clunky and I'm wondering if anyone can give me a reason why the first solution won't evaluate but the second will?
Hi,
I want to pull sample records lets say 1000 rows only from oracle database to sql server. Is there any option in ssis to limit the number of rows?
I have a SSIS package that opens an xml file, puts the contents into a string, then runs a stored procedure that dumps it into an xml column in a table. One of the xml files is huge. Putting the data into a ssis string causes an error. The length of the string variable is 58,231,886. The file will only get bigger.
How else can I get this data into a SQL Server XML field.
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??

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 the fields in my table:
ID, Title, Description, Price, ImageData, Active
I only want it to be possible to have two records at any time with Active=Yes. Active is a Bit, Yes/No, field.
Any help is appreciated.

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

[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
hello everybody
I created user "MyUser " with rights
1. public for database "Orders"
2. select, update,delete, insert to table Orders.dbo.PersonalInfo
I have table Orders.dbo.PersonalInfoChangeLog
( it keeps information on any update on Orders.dbo.PersonalInfo including
HOST_NAME())
So I don't want anybody to see even structure of this table(Orders.dbo.PersonalInfo ).
if person loged as "Myuser" he can use
1. sp_help PersonalInfoChangeLog
2.Enterpise Manager to see properties of the table
How can limit rights to see structure without generating Application role ?
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.
Thanks
I was wondering if anyone out there can help me as to how to limit the query results to show only the authors who have written more than one book?
SELECT a.au_lname, au_fname, COUNT(t.title_id)
FROM pubs..authors a
INNER JOIN pubs..titleauthor t ON (a.au_id=t.au_id)
GROUP BY a.au_lname, au_fname
Regards,
someone suggested I use:
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?
hi everybody,
Beside top statement what is the best statement used to limit the display the data?
Thanks...
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.
View 4 Replies View RelatedI 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.
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

Nothing much that i can do..!!
I am working on a report split into 2 Excel spreadsheets because it is roughtly 350 columns wide. I know this exceeds the MS Access column limit, but is there a way to build this in a single table in SQL Server? If not, does anyone have any ideas.
Thanks
I have a table tblclients where all my client information is. In my application, I can assign a client to a therapist which is simply inserting the client id (intclientId) into the table with the inttherapistId and the authorid was completed the transaction. because we want to know the history of the transfers, I have to have a separate table other wise I could have just crated a field in the client table for the therapist id.
Simply enough.
The problem is when I assign the client to a therapist more than once, on the client log (the screen that shows all my clients) the client appears twice- once for each therapist he has been assigned to. I only want the client to appear once- and show the name of the latest therapist he has been assigned to not all the therapist. The way I did the select was to do an left outer join on the tbltransfer based on the client id. Works but like I said it gives me the client twice, if I assign them to the therapist more than once. So here is my statement:
select c.strfirstname, c.strlastname, c.intlocationId from tblclients c left outer tbltransfer t on t.intclientId = c.intclientId
this works, but if I have more than one record for the same client in the tbltranfer (if I assign the client more than once) then the recordset that is returned contains two records- one for each therapist assigned and that my problem.
Any help would be appreciated.
I'm storing time series data in a table in SQL server 2000. The tablehas columns like: CodeEquity, PriceDate, LastPrice. To extract thelast price for a number of equities on COMMON DATES I have used thequery:select t.LastPrice,h1.LastPrice,h2.LastPrice,h3.LastPrice fromBlg_HistoricData t,Blg_HistoricData h1,Blg_HistoricDatah2,Blg_HistoricData h3where t.CodeEquity=114151 and h1.CodeEquity=112220 andt.PriceDate=h1.PriceDate and h2.CodeEquity=112580 andt.PriceDate=h2.PriceDate and h3.CodeEquity=112228 andt.PriceDate=h3.PriceDatethis works for about 20 self joined tables and then says syntax error.I'm wondering what sql limits it hits. Is it possible to do this inSQL for 300 tables?Thank you.
View 1 Replies View RelatedHi, guys!Some of my applications are sharing same SQL login/password to connectto a database called "MyDB" on server "MyServer" . The password isencrypted and stored in registry or some configuration file theapplications use. The applications use certain arithmetic to decryptthe password and then connect to MyDB.The problem is a few developers know the arithmetic. So virtuallythere is no security here.I am wondering whether I can do anything on the MyServer/MyDB to limitthe access to the database so that only connection from certainservers are allowed. Say I only want connection with this knowncredential to be established if it is from server "Mybox". Noconnections from any other servers will be allowed. So even thedevelopers know the login/password, they won't be able to do anythingif they do have the access to server "MyBox".(I know some of you would ask why I don't use application roles. Let'ssay it's due to "historical" reasons and it's not totally up to me tochange the way the developers use database.)Any idea? Triggers in Master? Not a good idea, isn't it?Thanks in advance,Gary
View 3 Replies View RelatedDoes anyone know if there is a way to limit certain users/logins to only use 1 CPU on a box with 4 processors? I need to somehow restrict CPU utilization for a user and I'm wondering if this can even be done in SQL Server 2005. Any help would be appreciated.
View 1 Replies View RelatedWe're very interested in having our application use SQL/e but we can't have the 4 gig limit. It makes sense to me that SQL/e simply should not be able to access a file over the network, and then you wouldn't have any reason to put a 4 gig limit on it.
At that point it becomes a very flexible alternative for remote users that need to have a large amount of data (i.e. documents, images etc.) with them.
We'd love to start building an abstraction layer so that we can support both SQL Server and SQL/e so that we can support network and remote users and not have the nightmare that is SQL Server Express installation. (care of the windows installer group's bugs...)
Thanks! Hoping for a favourable answer!
Hi there,
I am aware of the recommended practice of not mirroring more than 10 databases on a single instance but does this apply to 64-bit edition as well?
Cheers,
James.
Is there a size limit on the upgrade.exe to convert the SQL 2.0 SDF file to the SQL Mobile 2005/SqL CE 3.0?
I have a 184M SDF that I tried putting through the upgrade but i got an error that it exceed a 128M limit? Is there a way around it? maybe another parameter I need to pass in?
Thanks

Please, please, please, please just add limit/offset to the language.
7 years of working around this unnecessary limitation are enough. And that's just me personally, i'm sure there are those out there with a longer history and are more irritated. I know this isn't the first post on this here, nor will it be the last. I think that should be taken as a hint, and something should be done about this. Something like this:
SELECT column FROM table LIMIT 10 OFFSET 10
See, it wasn't that hard =) Now there are no ugly contortions to go through just to paginate the data. And don't recommend I return all 20k rows and do it on the client side, m'kay, or write ridiculous sql. It seems that for all the hard work that went into making those other features work that this could have been done. Don't lie, you know it could have! If there was a voting feature for suggested improvments, or a bug tracker + watch list that functioned the same, it would help. Others do that, as well.
//Another Annoyed DeveloperAnd seeing as there aren't any feature/suggestion channels that work (see:connect), I guess this forum is the best we can do. Sorry.
