I want to optimize a query for fast retrieval of the first row
and after the rest of them automatically.
I used the hint OPTION (FAST 1) but I don't get the hoped results, any idea?
Thanks.
my package contains
Two connections ==> one is using OLEDB connecting to SQL server 2005 and the other using ADO.NET's ODBC option to connect to mysql;
Two "Execute SQL Task" ==> one gets maximum ID(bigint) from a SQL server table and the other gets the maximum ID(unsigned) from a mysql's table and bind them to two variables ID1(string) and ID2 (int 64). http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=1902297&SiteID=17&mode=1 ;
And one DataFlow whose data source is DataReader Source which queries mysql "select * from table where ID > cast(@ID1 as signed) and ID <= cast(@ID2 as signed) ". To debug, I put a DataViewer between Data Flow Source and Data Flow Destination.
Run the package, I found no data coming into DataViewer and no error message as well. However if I remove the "<=" sign and change the DataReader Source query to "select * from table where ID > cast(@ID1 as signed)", It works perfectly. Initially I thought it's variable @ID2's issue. But if I replace "<=" sign with ">=" sign in the query ==> "select * from table where ID >= (cast(@ID2 as signed) -100)", there is no problem. After tried many times, I found that query just doesn't work with "<" sign or "between". Plus the result of running package tells it's successful but just no records got inserted into Data Flow Destination.
Anyone could help? Thanks!
Hi,
I am using the AutoFetch Option with Fast Forward Cursors with SQLOLEDB to access SQL Server 2005. This really works out but for the first I execute the query only.
But as I use parameterized statements, when I re-use the cursor, just re-binding new variables and re-executing it again, the AutoFetch does not work any more.
I noticed that thru the SQL Server Profiler. I see a sp_cursorfetch been called at the second time the cursor is re-executed.
Does anyone know how to work it out?
Thanks in advance.
Marcelo.
I must be doing something wrong.
Code Block

ssql.Append("SELECT Facility FROM FINDINGS")
rdr = dba.OpenResultSet(ssql.ToString)
Try

While rdr.Read
...
So here is the problem. The normal function is to initiate the insert by pression a button. That should go through all the steps then hit the dtblFindings_Initialize command and rebuild the datatable. However when it happens for the first time (i.e. the first facility going into the database), the SELECT statement always returns nothing.
If I stop the application and Pull the database to the desktop, the row has been inserted. So I feel that I am somehow doing something wrong, not closing something, not initializing something....argh! Please help!!
I'm using a performance monitor counter with an alert to catch merge replication conflicts. As you might have seen in my earlier psting this alert keeps running even if all conflicts have been resolved. After almost 2 days searching I found that in the table master..sysperfinfo there all the PM counters are stored still has the value 4 for conflicts/sec. When I manually create a new conflict this value becomes 5 which is nonsense since it's not the number of conflicts per second but the total number of conflicts since I started the server. If I check in PM it shows the correct value, whih of course is zero 99% of the time. Has anybody ever experienced the same kind of problem??
Or does anybody know a way of resetting the values in sysperfinfo. Even after allowing direct updates to systemtables I still can't modify the table.
Thanks in advance

Does anybody know how to work with two (or more) databases in SQL Server 2005; or where that information can be obtained? I searched online, in BOL and asked in this forum but with no success.
information in this posting does not work; results in invalid object name (source database) and/or database does not exist (destination database) errors:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=292125&SiteID=1
this post about the database does not exist has received no replies:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=295742&SiteID=1
Of course, both databases exist and their names are valid. Both can be accessed individually thru SSMS and a VB app I am coding. The problem is when trying to work with both of them.
Any information on the subject of working with multiple datatabases and/or links to said subject would be appreciated.

The company that I work for has multiple database instances across two data centres in two different cities. All of these databases have front end applications reading/writing data to them.
Now, we have taken an initiative to merge all databases into one consolidated database. Then we want this database to be available in the other data centre. We'll have front application running at both locations reading/writing data to the databases and want it to be written to the other database too. These systems are in production 24/7 and we cannot afford any downtime over 5 minutes.

I'm pretty new to DTS, so forgive me if this is basic. I created a simple DTS package to run a query and export it to a text file. I can execute the package fine from my workstation through EM, but when I try to execute the job to run the package I get this error:
Error = -2147467259 (80004005) Error string: Error opening datafile: Access is denied.
I think that maybe SQL Agent doesn't have the right permissions to write to that network drive. What should the permissions be?
This is probably very simple, but I can't get passed this problem.
I have a report in MS Access that uses info generated by a query. One of the text fields in the query contains either the word 'Select' or the name of a course.
The report should display a space if the value is 'Select', or the actual value of the field in any other case. The field can never contain a null value.
I've used:
=IIf([optVoc1]="Select","",[optVoc1])
in the text box on the report, but this only returns #error regardless of the actual content of the field.
What am I doing wrong?

Hi all,
I create and schedule a SQL job to run every minute to update a table base on certain condition but it doesn't work. Job history says successful every time but the table doesn't get updated.
However if I move it to Query Analyzer and run it under dba, it will work. Thinking that it may have to do with the user the job run as, I then change run as user from self to dba. But still SQL job won't update my table.
Anything about user permission or security that I can check? Or it there any other possibility?
TIA

When I try to install the problem I get the following error.

I'm working with mssql 6.5
I have an primary key column with Identity property.
And at the moment server doesn't insert the proper value to this column.
Error message is following
Msg 2601, Level 14, State 3
Attempt to insert duplicate key row in object 'Spot' with unique index 'XPKSpot'
Command has been aborted.
The datatype of this column is int, and number of rows ~17000.
If I execute select @@identity it returns null.
I'm combining first name, last name, middle name, and an ID number together into an alias. Then I need to match that alias with a variable passed to the page (its a search results page). The problem is it claims that there is no table with the name of my alias. Anyone know what I'm doing wrong?
A mockup of the SQL looks like this:
SELECT UserID, Last_Name + ', ' + First_Name + ' ' + Middle_Name + '.' AS name
FROM Table
WHERE name LIKE 'variable%'
Everything looks right with the results, if I take out the WHERE clause it has name displayed properly and joined together with the rest of the data in the results properly.
Thanks in advance for any help that can be provided!

I have a drill through that passes four parameters. Three are passed from the current selections in that reports parameters and the fourth needs to be the customer name they click on in the body of the report so it's passed as Fields!fieldname.Value. When I click on the customer name, the drillthough fires but the report simply doesn't load. If I remove the parameter from the field clicked on and just pass the three parameters, it goes to the drill through correctly and that fourth parameter just sets to the default for that parameter in that report.
I can then simply check that parameter and select the value from the list that is exactly the same as the value I was attempting to pass it in the drill through and report refreshes correctly.
Whatever it is, is something in the manner that the value is passed in the drill through specifically.
Any ideas?
Hello,
I've rescued a MDF and LDF files off a client's old server, and I wanted to attach it to our own, but I can't seem to get the command to work, basically I have these two files, which I've dropped on our server:
C:Program FilesMicrosoft SQL ServerMSSQLDataMYCLIENTNAME_Data.MDF
C:Program FilesMicrosoft SQL ServerMSSQLDataMYCLIENTNAME_Data.LDF
So when I do a
SP_ATTACH_SINGLE_FILE_DB 'somedb','C:Program FilesMicrosoft SQL ServerMSSQLDataMYCLIENTNAME_Data.MDF'
It says the LDF path my be incorrect, and that there's two other files that are missing:
MYCLIENTNAME_LOG (no extension)
extra_log (no extension)
I thought the whole point of the command is that you only need a single file?
Its very hard to go back to the client's old server and try to find these two files, and it doesn't really matter if we loose a bit of data, so long as the bulk of it is available.
Update: I think I've found the answer...its not possible to do this, it really needs all the log files.
Any workarounds?

SELECT CardID as CardID, [dbo].[cc2_Helper2](CardNumber, convert(varbinary, CardID)) as CardNumber FROM [dbo].[cc2]
go

WHY? Note that the conversion to VARBINARY was moved from the call to DecryptByKeyAutoCert to the call to cc2_Helper2. That is the only change...
But if I declare @vBin as VARBINARY(256) then it does work! Guess I'm a little confused on declaring vars...anyone can elucidate? Thanks.
In the Data Source Wizard the "insert,delete,update" advanced options are greyed out.
The table's PK is not an identity, but a uniqueidentifier.
I have been looking at this for over a day now. I cannot see why this procedure does not work, its so simple.
No matter what happens it always returns 0. If it locates a record, it doesnt update it, yet it still returns 0.
It should not be returning 0 if its not updating so I can't figure out why it does.
Why does this always return 0?
