Recomendation Request: DBLib Usage Upgrade
Jan 16, 2008
Some backgroud, sorry if its long.
We currently have a C++ application thats uses DBLib to insert data from a socket conection into a SQL 2005 Database.
The data from the socket is Real time Market Quotes (Ticks) and it the application takes the quote messages, formats them and inserts them in to the Database via DBlib Bulk API, and batching the insert at 1000 messages / sec.
As any in the financial industry knows, the message rates have expoloded over the past year and they keep inceasing, DBLIB has always been the Highest Performing way to get these Quotes ticks into the Database fast.
I house testing has show that DBLIB does top out (for us) at arround 15,000 messages per second which under a market swing can excede 20,000 / sec. This then leads us ot a queueing situation (Application Queue) till the traffic slows and the Applicaiton can flush all the data to the Database. We get arround this DBLIb limitation by splitting the insert duty to more them on process where each process's DBLIB connection has that 15,000 message celiing.
This application does only inserts to a table, no updates or deletes, every tick is a row.
The Question...
With DBlib being Depricated through 2000 and 2005 we now would like to redue the application with a more supported interface to SQL Server. I am researching the SQL 2005 Native client API's and I am looking for which method the SQL Native Client (ODBC) or the SQL Native Client (OLE DB) are the close cousin to the old DBlib to do this type of Real time Bulk operation?
Thanks in advance for all hellp.

I have an application that was converted from using DBLIB bcp to using ODBC bcp. All other field/data types bind are updated correctly, but dates put in the date
1753-01-01 00:00:00.000 when it should be NULL. The variable is a char [24] and the first item is set to ( dbLoanBankruptcy.MotionforReliefReqDate[0] = NullChar; ).
Is there any example or way to put the date in as null when the variable is null and an actual date as needed?
bcp_bind(LoanBankruptcyDBPPtr, (BYTE *)&dbLoanBankruptcy.MotionforReliefReqDate, 0, 23, NULL, 0, SQLCHARACTER, 13)
Thank you,

Greetings,
I have a client whose DBA upgraded their SQL 2000 database to SQL 2005. They still have it running in 8.0 compatibility mode, for various reasons, and would like me to help them develop a migration strategy to get them to full 9.0 compatibility.
My question is: can I run the Upgrade Advisor on a SQL 2005 engine database running in 8.0 compatibility mode and get anything useful? I already know there will be some issues with existing DTS packages but it would be nice to catch any other issues in advance.
I know that the Upgrade Advisor was run before the upgrade took place but to my knowledge the report was not saved and none of the recommendations were followed.
Any help would be greatly appreciated.
Cheers,
Lon

Hi,I'm going to explain as clearly as possible:I have two tables:Relationships(relation_id, table1, table2)Relationfields(relation_id, field1, field2)In Relationships, relation_id is the primary keyIn Relationfields, relation_id is the foreign keyI have a front-end interface that allows the user to add records toRelationships and Relationfields as followed:The user selects a table1 and table2 values from listboxes. These arereal table names from sys.objects, so then the user can select fieldsof these tables on which he wants to create a JOIN.Anyway, I can easily insert the table1 and table2 into Relationships(relation_id is an auto-increment). Then I need to get the relation_idof this new Relationship (easy since I know which values I've insertedand table1-table2 associations are unique.Now the PROBLEM :I need to insert into Relationfields all the fields selectioned by theuser for each of the two tables . But the user might have selectedseveral fields from table1 and table2, so I need to pass A LISTPARAMETER to my Stored Procedure as I don't know how many values offield1 and field2 there is going to be.I hope this is clear enough. Is it possible to achieve what I want ?Should I pass an entire concatenated string with values separated bycomma or whatever and then decrypt it in the stored procedure ?Thx

I've got a table that houses the data for several routes, (routeID, pointID, Longitude, Latitude and Elevation). a set of Points make up a route. I'd like to programmatically access specific points and I'm trying to figure out how to request...say the third point in my dataset. I'm new to SQL, but I was able to figure out that I can find the row number by using the SQL syntax:SELECT ROW_NUMBER() OVER(ORDER by PointID) as 'Num', Latitude, Longitude, Elevation
FROM [PointTable]
WHERE (RouteID = 5)
But I cannot (or do not know how to) add a clause that saysAND (Num = 3) So can someone show me how to request a specific row?

Hie,
I have a big request involving 24 tables working with Oracle. I`m porting my application onto SQL Server 6.5. The problem is the maximum number of tables: 16.
I did create a view with 9 tables and recontruct my query with the 15 remaining tables and the view. I tried and I got an error message:
"Msg 4408, Level 19, State 1
The query and the views in it exceed the limit of 16 tables."
Here is the query:

VTM VTM2,
VTM VTM3,

VTM VTM5,
V_DEV DEV_B,
NIE,
POS,
TIE,
TLP,

There is only 16 tables...
Can anyone explain me why it does not work.
Thanks a lot.

HI There,
Im now working on a assignment where i have hierarchial tree structure arrangement for representing an health care. This is supported by SQL DB 2005.One of the node in the tree is dissolved and all it functionality have to ported to the other tree node which share the similar structure.
Problem in porting is complex due to the following things
1. There are capabilities and permission associated with the each node.
2.each node has a unique identifier across the three (note: though this seems to be of no problem it might become issue when search occurs for eg. a->b->c search now becomes a->b->x->n ->?).
3.Already there are messages left in the DB. Please can anyone help me how can i initiate this migration. Im very new to the design and im just started "ABCD" of it.
Thanks in advance.
Cheers,

I am not sure if this belongs under this forum or 'New to SQL' so please feel free to move it if necessary.
Following on from an issue i have had with sysdepends and syscomments tables filling up, I have been trying to research what these tables are and how they get filled up (i.e. what is the trigger to insert a row into these tables).
Unfortunately on all my web searches and book searches i have not found anything much more than 'They are system tables'. From what i have gleaned, it looks like every time a stored procedure or database object is changed, then this will create a new entry into the sysdepends table which highlights what the new object is linked to.
Is this understanding correct? And does anyone have any other sources of information which might give me a better idea of what and how these tables are about.
Many thanks in advance.

Hi,I've got two primary keys in a table:Constraint(QueryId, ConstraintName)In a stored procedure I select {QueryId, ConstraintName} couples thatmatch some criteria, and what I want to do is specifying in my a SELECTstatement that I want all of the {QueryId, ConstraintName} that are notin my stored procedure result. With only one field, it would be easy :Select * from Constraint where QueryId not in (Select QueryId fromOtherTable)My explanations are not great but I think it's enough to understandwhat I want.Select * from Constraint where QueryId and ConstraintName not in(select QueryId ,ConstraintName from OtherTable)--> of course not correct, but then how can I do that ?Thx

I Stipulate that I am the most ignorant creature in the universe, incapable of following exactly written directions available all over the internet to install Microsoft Visual Web Developer 2008 Express Edition and SQL Server Express, in a way that will enable me to make a connection to SQL Server Express.
Having Stipulated the above, is there someone out there that can explain to me, in a dumb-proof way, how to do it in a way that is understandable to the most ignorant creature in the universe?
I am running Windows XP SP2 with all the lattest updates, frameworks, etc., and using IIS.
Thanks in advance for any guidance!

The dynamic SQL at the buttom causes a error:
Msg 402, Level 16, State 1, Line 9
The data types ntext and nvarchar are incompatible in the equal to operator.
I think it is due to the one of the where conditions [URL] = @old_URL ,both are set to NULL(@URL=NULL, @old_URL=NULL).
How do I make changes to the SQL statement to compare the conditions where NULL comparsion is inevitable.
exec sp_executesql N'UPDATE [Announcement] SET [Atype] = @Atype, [Title] = @Title, [Content] = @Content, [URL] = @URL WHERE [AnnouncementID] = @old_AnnouncementID AND [Atype] = @old_Atype AND [Title] = @old_Title AND [Content] = @old_Content AND [URL] = @old_URL',N'@Atype nvarchar(3),@Title nvarchar(3),@Content nvarchar(41),@URL nvarchar(4000),@old_AnnouncementID decimal(1,0),@old_Atype nvarchar(3),@old_Title nvarchar(3),@old_Content nvarchar(41),@old_URL nvarchar(4000)',@Atype=N'CMC',@Title=N'aaa',@Content=N'asdfg',@URL=NULL,@old_AnnouncementID=6,@old_Atype=N'CMC',@old_Title=N'aaa',@old_Content=N'asdfg',@old_URL=NULL
Any help would be apprecaied,
Ricky.

Hi everybody.
Got a nice little problem here. I have a accessdatabase containing 100 000 rows. Im fetching these rows to a dataset and then inserting them, row by row, to a MSSQL dB. The dB and IIS is running on the same server. I also have full control over this webserver, so I pushed the Server.ScriptTimeout value up to 3600 sec (both in IIS and in the c# code) but when executing this query (witch aprox. take me 8 minutes) I recieve a Error Code: 408. The operation timed out. The remote server did not respond within the set time allowed error.
Someone got a clue for me? :)

Is it possible for SQLServer to make a http web request in a stored procedure? I know that you can configure it to send email, but I'd rather do that on the webserver side, and that needs to be triggered by a request of some sort. I have a sp that runs nightly, and I'd like it to send out a http request when its done so that I can do further processing/send email/what have you. I haven't been able to find anything on this subject in any of the books I have, and my google-fu isn't strong enough. Thanks for any hints.

Hello! I am learning the RS from SQL 2000 and am having an issue. Does anyone have a "Working" example of how to render a report and render images embedded/external/database to the web? I have the report generated, but the pictures just don't want to render (through the web). I have contacted my hosting service (who are all supposedly Microsoft Certified Technicians) and they have no clue why it won't work. I have gone through every online resource that I have been able to find (including the Microsoft thing about the RenderStream) and it still doesn't work. If any of you have a working example of this, it would be very helpful!! As of right now, I am using a database image, and this is the ASP.Net code that I have been using:
Dim rs As New newafp.RSService.ReportingService
rs.Credentials = New System.Net.NetworkCredential("domainusername", "password", "")
Dim items As newafp.RSService.CatalogItem() = rs.ListChildren("/", True)
Dim results As [Byte](), image As Byte()
Dim streamids As String(), streamid As String
results = rs.Render("/NewUserLetter" & Location, "HTML4.0", Nothing, "<DeviceInfo><HTMLFragment>True</HTMLFragment><StreamRoot>/newafp/</StreamRoot></DeviceInfo>", Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, streamids)
For Each streamid In streamids
image = rs.RenderStream("folder/NewUserLetter", "HTML4.0", streamid, _
Nothing, Nothing, Nothing, Nothing, Nothing)
Dim stream As System.IO.FileStream = _
System.IO.File.OpenWrite(Server.MapPath("") & "" & streamid & ".jpg")
stream.Write(image, 0, CInt(image.Length))
stream.Close()
Next
Response.BinaryWrite(results)
