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.

We are running SQL Server 2005 express on Windows 2003. The database server gets significant amounts of data.
Because of the 4GB data limit we have a daily cron task which goes through and deletes data older then 90 days.
We would like a way to archive this data instead of deleting it. Is there any way to take data and compress it and store it in a different way, so that if needed, customers can query directly out from the compressed data? Cleary querying from compressed would be slower but that is ok.
Any other solutions that would allow us to archive data instead of deleting it? Thanks.
Hi
I'm new to SQL Reporting Services and I've been asked to create an online environment for a client where their customers can log on and view a report. The client wants to make sure that each customer can only see data that is relevant to them, and that other customer's information is hidden from whoever is logged on.
Can this be done through a username/password setup or is the solution more complex?
Thanks very much!
Hai Every one
i am facing a werid problem it is related to storing a long text data in SQL 2000 the text data is some thing like the following
"dshjfsjlksdjakdjlksadjfeidkadflkdsajfieawirfjalkdfjsakdfjaiekdvnmckaumnmmmmmmmmmmmmmmmoadifdjsakdjfauiereoweiiiiiiiiiiiiiiiiiiiiiiiiiiidalfkjdsa,mlfdsdflvmsaldifsdjfskladfakdfjakladkalfkfadkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkadlkfjaidfajfkamcmmmmmmmmmmmmmmmmmmmmmmmmmmmmmiadlmfalierfmaerjeaiaelelllllllllllllllllllll..."
in short it is really long so i opted to go with TEXT data type as it states that it can store more than 8 kb but when i try to insert this data it gives me error stating that Text data type cannot be of length more than 128...........?
What am i doing wrong........if Text is not the proper datatype to store such a data then can anyone suggest some thing better...............
Thanks in advance

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?
Hello,
I have 2 table, "table1" is the source one and the other one "table2" is the destination.
Columns in Table1 and in Table2 are nvarchar(max).
Data loaded from table1 is performed by SSIS OLEDB data flow source, I have found out that opening "Data flow Path Editor" in the Metadata, columns are as: DT_WSTR with lenght 4000.
First question:
Why SSIS limit the column to 4000.
Then I get some error for this issue, with the error:
input column "col1" (xxxx) and reference column named (coln) have incompatible data type.
As written before both columns are string, the problem is that SSIS limit the lenght of the string to 4000.
How can I solve this issue?
Thank

I use decimal(2,2) as data type but an error accour and this is the message
"- Unable to modify table. Arithmetic overflow error converting float to data type numeric.The statement has been terminated."
Can you help me..
thanks
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 guys, is there any way to solve my problem as title ? Assuming my stored proc is written as below :
CREATE PROC TEST
@A VARCHAR(8000) = '1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,...,5000'
AS
BEGIN
DECLARE @B nvarchar(MAX);
SET @B = 'SELECT * FROM C WHERE ID IN ( ' + @A + ')'
EXECUTE sp_executesql @B
END
GO
Hi! I tried to save some image data, but it get truncated at 8000 (the table column is defined as Image). I then wrote a converter to try ntext-datatype instead, but it gets truncated at 4000.
Error message:
System.Data.SqlServerCe: @3 : String truncation: max=4000, len=4168
The code uses only ADO entity framework for database access. Is there a way to store binary data larger than 8000 bytes? I am running SQL Compact 3.5 sp 1 BETA.

I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.
The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.
Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.
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??

View 2 Replies View RelatedHi 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
hi,i have a union statement that works like a charm:SELECT
[Name],
[EventID] AS [ItemID],
[TourID],
[Date],

[Date] AS [SortDate],
[Type] FROM [Events]
WHERE
[TourID] IS NULL

[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 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.
