Verify Data Source Viable Before Proceeding
Feb 12, 2004
I've completed my first SQL project, for which I've built a DTS Package. First thing it does it drop all records in the destination table, before importing new records from a txt file and then massaging them.
After I got done, I realized that if the data source is not available for some reason, the records will still be dropped, the process will fail, and the destination table will be left empty. In this case, leaving the existing records intact would be preferable to not having any.
How can I test that the txt file exists before dropping the records?
Thanks,
Randy
ps: Users will maintain a link to the table. I plan to update the table after business hours. If someone happens to have their linked application open while I'm trying to update the table, will it fail?

Im using a store proc in SQL server.I use one table to store my hockey statistics data of each player in the league.When i submit my form i would like to check if there is any sheet of that player that allready exist .. If so then i do update.. if it does not exist i do the insert statement.Here the way i figured it out ! One store proc to do the work of the insert or update. And one to check if the player exist in the statistics table. But i just cant find a way to return a good value from my second store proc. Does my logic make sence ? any ideas ?thank you<code>create procedure Hockey_Player_UpdateForwardStatistics
@LeagueID int, @GamePlayerID int, @Games int
as
declare @PlayerID int
@PlayerID = Hockey_CheckPlayerStatistics(@LeagueID, @GamePlayerID)
if @PlayerID = 0begininsert into Hockey_PlayerStatistics( Games)values( @Games)end
ELSE
beginupdate Hockey_PlayerStatistics set Games = @Gameswhere LeagueID = @LeagueID and PlayerID = @PlayerIDend</code>

I've got a table with 6 fields :
EmployeeAccess
(MasterID, LoginID, AccessID, Storage1, Storage2, Storage3)
that needs to be updated using the data in the following spreadsheet
NewEmployeeAccessData
(ID, MasterID, AccessID1, LoginID1)
There is a 1:1 relationship between the two tables..I'm trying to code a pair of update statements on the EmployeeAccess table (1 for LoginID, 1 for AccessID) with the following logic:
If LoginID is NULL, then Update LoginID with new LoginID1 value,
If LoginID is not null, and Storage1 is NULL then Update Storage1 with New LoginID1 values
If LoginID is not null, and Storage1 is not NULL and Storage2 is NULL then Update Storage2 with New LoginID1 values
etc etc...
The same applies when trying to populate the AccessID column
If AccessID is NULL, then Update AccessID with new AccessID1 value,
If AccessID is not null, and Storage1 is NULL then Update Storage1 with New AccessID1 values
If AccessID is not null, and Storage1 is not NULL and Storage2 is NULL then Update Storage2 with New AccessID1 values
etc etc.
I have no control over the schema of this table so I'm trying to work the logic on how to update the columns in my table only if the corresponding column data is NULL, else update the next non NULL Storage column.

I'm setting up a Maintenance Plan to do a backup for me in the night of my SQL Databases but before the backup starts I have created a SQL Server Agent Job that runs a DOS batch (.bat) file using CmdExec. The problem is I need this process to finish processing before the rest of the tasks run in the Maintenance Plan. It seems like SQL Server Agent Job Task tells the batch file to start running (and it runs fine) but it just continues to the next task and does not wait for it to finish.
Is there any way I can configure this to wait before proceeding?
Thanks, Mark

After digging for some time now into the "guts" of SSRS, I am wondering if anyone out there has any ideas which might help me at this point.
I am trying to write an Invoice report.
Each report can have 1 to n invoices on it.
Each invoice can have 1 to n line items (spanning several pages for the larger ones)
Each page must have a fixed header and footer with account and payment information on it (the page header and page footer work OK for this).
And here is the problem. Each invoice must also include 1 to n images at the end of the report. 2 on a page and take up an entire 8.5 by 11 inch page. (spanning many pages when many line items exist)
Since the report already has a page header and footer with the report detail stuffed in a table in the middle of the page (report body), I am stuck.
I have read several posts which talk about having a can-grow container with a subreport in the existing footer, but I can't even come close to getting this to work. My footer would have to take up the entire page and having nothing but a subreport in it.
I can not provide a link to the images in the report, as each report must print in its entirety without user involvement (no drilling down).
I am thinking that my report is too complex for SSRS at this time. I would love to be proven wrong by someone on this forum.
Thanks for any and all replies.

Currently, our application is issuing a 'select count(*) from systypes' command to check to see if the database connection is live (has not been reaped by the firewall.) This is somewhat inefficient. Perhaps a less expensive way to implement this functionality is to issue a ping statement to the instance? At least a more simple SQL query is needed.
I'm sure this function is typical in application architecture. What recommendations do you have for confirming that a database connection is alive and viable from the application?

Hi all,
We are running SQL Server 2005 Standard edition on a Vista Business machine. Whenever we try to use DTS to import or export data we get this message:
The SSIS Data Flow Task could not be created. Verify that DTSPipeline.dll is available and registered.
Of course we have explicitly registered this dll and others.
Also we reinstalled SQL Server (and did it again. And did it again).
And we did the same for Visual Studio Standard (and again).
Any ideas in this elaborate group?
Thanks,
Tjerk

***********************************************************
How can I create data source and data source view and model and structure?
Please say code of that, and guide me.
databasename and srv is unknown.
Do I add other reference with analysis services?

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.
Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?
Thanks in advance

Today I was making a few reports.
When I tested the reports in Visual Studio, they worked great: I got the expected result.
But when I deployed the reports to our reportserver the problem started.
When I click on the directory in which my reports are deployed, I got my 4 reports.
Till now everything worked correct.
But when I click on a report to view the results it went wrong.
I got an error:
"Cannot create a connection to data source 'Live'"
(Live is the name of our data source).
We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work.
I also have tried it with all the roles assigned on my account, but then it still won't work.
When I modify the data source, and set it to another server en database it works.
The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server.
Maybe that is the problem?
Can someone tell me what is wrong?

I was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.
The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.
Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?

Hi all, i got this error:
[DTS.Pipeline] Error: "component "Excel Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
and also this:
[Excel Source [1]] Warning: The external metadata column collection is out of synchronization with the data source columns. The column "Fiscal Week" needs to be updated in the external metadata column collection. The column "Fiscal Year" needs to be updated in the external metadata column collection. The column "1st level" needs to be added to the external metadata column collection. The column "2nd level" needs to be added to the external metadata column collection. The column "3rd level" needs to be added to the external metadata column collection. The "external metadata column "1st Level" (16745)" needs to be removed from the external metadata column collection. The "external metadata column "3rd Level" (16609)" needs to be removed from the external metadata column collection. The "external metadata column "2nd Level" (16272)" needs to be removed from the external metadata column collection.
I tried going data flow->excel connection->advanced editor for excel source-> input and output properties and tried to refresh the columns affected.
It seems that somehow the 3 columns are not read in from the source file?
ans alslo fiscal year, fiscal week is not set up up properly in my data destination?
anyone faced such errors before?

I've question about how to handle structural datamodel changes in a datasource of PowerPivot. Suppose I'm developing a starmodel in SQL Server and sometimes a datatype changes or a name of a field changes in a table. It seems to me that PowerPivot handle this not gracefully as Analysis MD does (mostly). I received an error because of a wrong fieldname or even no error when a dattype changes in PowerPivot. Is this common or do I something wrong here. Does this mean that every time the datamodel changes the PowerPivot should be recreated? Or am I missing the clue here?

Was wondering if there was a best practice minimum permissions for creating a SQL login to use when setting up a new shared Data source for SSRS report manager?
Something along the lines of them being a data read for the DB and permissions to update tempdb?
Would have thought it not advisable to have the login be able to update the main db...

A data reader is using a connection manager to connect to an ODBC System DSN . A query in the SqlCommand property is provided. Data is being truncated in the only string column . The data type in data reader output-->external columns shows as Unicode string [DT_WSTR] Length 7.
The truncated output in a text file is the first 3 characters from left to right . Changing the column order has no effect.
A linked server was created in SQL Server Management Studio to test the ODBC System DSN using the following:
EXEC sp_addlinkedserver
@server = 'server_name',
@srvproduct = '',
@provider = 'MSDASQL',
@datasrc = 'odbc_dsn_name'
Data returned using "OPENQUERY" does not truncate the string column indicating that the ODBC Driver returns data as expected with sql 2005, but not with the Data Reader.
Any assistance would be appreciated.
Thanks,

I've got a report that is using a cube as a data source and I can't get the report to show all the data. Only data at the lowest level of the cube is displayed. The problem is that most of the data I'm concerned with is at higher levels. There's no problem with the MDX. I get the correct results when I run the query.
I'm using a table to show the results. I've also tried a matrix, but I get the same results. I'm using SSRS 2005 and SSAS 2000.
Anyone have experience with this? Am I missing something simple?

Hi,
I am pretty new to SSIS. I am trying to create a package which can accept data in any of several formats. i.e. CSV, Excel, a SQL Server database/table and import the data into my destination database.
So far i've managed to get this working OK. However I am now TOTALLY stuck. I'm currently trying to just concentrate on the data sources being a CSV (using a Flat File Data Source) and/or an Excel Spreadsheet.
I can get the data in and to my destination using a UNION ALL component and mapping the data sources to it so long as both the CSV file and the Excel spreadsheet exist.
My problem is that I need my package to handle the possibility that only the CSV file might exist and there is no Excel spreadsheet. In which case i'd like the package to ignore the Excel datasource completely. Currently either of my data sources do not exist I get errors and the package terminates.
Is there any way in SSIS that I can check all my data sources to see which ones exist (i.e. are valid). If they exist I want to use them. If it doesn't exist i'd like to disgard it (without error - as long as there is a single datasource the package should run)
I've tried using the AcquireConnection method in a script task on each of my connections, hoping that it would error if the file/datasource did not exist. It doesn't though (in the case of an Excel datasource it just creates a empty excel file for me).
The only other option I can come up with are to have seperate packages depending on the type of data we want to import and then run a particular package depending on the format of the source data. This seems a bit long winded. I am pretty sure I must be able to do what I want to achieve but I can't work out how.
I'll be grateful to anyone who can send me any tips/hints/links on how I can achieve this.
Many thanks

I am new to SSIS programming, so bear with me if my question seems naive to you gurus. I have a situation that needs to set the data source for a data flow from external .NET application ('external' means that the application will run on different process than the SSIS). I am trying to set the data source on which the data flow works from my C# application in a DataSet format. Ideal solution is not to save the DataSet to any file on harddisk (I know that will work, but has the overhead of writing, reading and managing the temp file). What I want to achive is that the business logic of picking data for SSIS Data Flow to process is controlled inside my C# application, the Data Flow just does what it does best - Transformation. Have any of you successfully done this before?. Thanks!

I have a stored procedure that receives an input parameter of ReporID and then sends back the appropriate dataset to the data-driven subscription. In the stored procedure, there is some concatenated sql in producting the final select statement to send to the subscription, but it is generating the following error:
The dataset cannot be generated. An error occurred while connecting to a data source, or the query is not valid for the data source. (rsCannotPrepareQuery) Get Online Help
Insert Error: Column name or number of supplied values does not match table definition.
Because there are some optional columns that need to conditionally appear based on the report, I can't avoid concatenation. My only other option is to have hundreds of individual tables to source all our reports, which I don't have time to manage.
Please let me know how I can allow the data-driven subscription setup process to discover the columns for my concatenated SQL so I can seutp my schedules based on the single stored procedure with all my logic nested in my table structure.
Thanks.

I'm new to sql server. Last week I made my first cube. Everything went fine. But when I want to explore the cube (from the explore panel in Visual Studio 2012) in Excel then I'm getting the error "Initialization of the data source failed".
Check your database server or contact your database administrator. Make sure the external database is available, and then try the operation again. If you see this message again, create a new datasource to connect to the database.

Hi, i'm wondering which is the best way to search data in a SQL Server.
I reach data using Data Sources and Data Views and also with OLE DB Source with a Data access mode: Named query.
I have to write the data into a Flat File. So, does any one knows which is the best practice for this? Or any one of the two are good choices?
