Dynamic PIVOT Table As Data Source View
May 29, 2008I would like to use a dynamic pivot table in my data source view. It seems that a named query can be only one sql statement. So, I cannot use my multi-statement procedure that creates a dynamic pivot table output.
What is the best course of action here? I could hard-code my pivot table query. I could maintain a redundant table in the pivot format. Do I have any good options?

Dynamic Queries With Data Reader Source Adapter
Apr 16, 2008I am a business user trying to build an incremental ETL package with SSIS. I have a working prototype on SQL Server 2005 where I select the max(ID) from the last successful run and pass that value into a variable. Then, in my Data Flow step, I select an OLE DB source adapter and use this variable in a custom select statement.
Here's my challenge....the live data is actually in a Postgres DB so I have to use a Data Reader Source adapter. When I try to pass my variable to this adapter the job bombs out. Does anyone know how to dynamically update the query text inside a Data Reader source adapter using variables or otherwise?
Dynamic Source And Dynamic Destination
Apr 15, 2008I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have

How Do I Add An ODBC Connection Data Source As A Data Flow Source
Mar 2, 2007I 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

DTS W/dynamic Source && Query
Jul 20, 2005I'm looking for a way to transform the contents of n source tablesinto a single destination table. This by itself is no problem.However, the name of the source tables change, so I'll need to basethe transform task on a global variable that I can update via externalcode. Not sure how to do that. I'm ok with executing the package 10times if there's 10 source tables.The last unknown piece is modifying the query used for the transform.There are 10 columns in the source table, but there are 12 columns inthe destination table. I must provide the 2 missing columns. They willsimply contain a year and month, ie. 05 2003.I'm taking a bunch of source tables (for a given month and year) androlling them together into one destination table, and carrying overthe month and year. I assume the month and year would also be globals.But I'm not sure how to incorporate them into the transform task sinceit wants strict SQL syntax.Any help is appreciated, thanks in advance!

I have a requirement to create a dynamic SQL Command in an OLE DB Source due to the fact that I need to read data from another database based on a date range. For example, the SQL command would look like

Dynamic Database Source Changing
May 2, 2006Hi,
I am building a data warehouse for a customer who has systems located in two different countries.
I need to import that data from four seperate databases, which all share the same structure.
To do this i have created 20 packages to import that data from the source database. What i would like to do, is at run time set which database the SSIS package should get its data from.
In sql 2k this was easy with a global variable that was set, then use a dynamic properties task to set the data source.
How can i achieve the same result in SSIS? the data source is an ODBC connection, with the four ODBC connections having similar names, eg ABC_NZ, ABC_AU
Thanks in Advance!

Dynamic Mapping For Source/Destination

Hello,
What I'm trying to accomplish is to have a variable names "SourceTable" and "DestinationTable". So for each SourceTable, the DestinationTable will have the same columns. All I need is to auto-map these columns between source and destination via code?
Is this possible?
Thanks,

Dynamic File Name For Flatfile Source In SSIS
Apr 11, 2008I have CSV file as source for SSIS package every time the filename will be changing like trd_1990M1_1990M12.csv,trd_1991M1_1991M12.csv , trd_1992M1_1992M12.csv etc.,
so it will vary as per user selection . i need to run the same SSIS package to execute the different file name with the same structure.
Please let me know the solution for that how to pass the file name dynamically to SSIS package.
Dynamic Filedlength Of Varchar Fields In Source
Nov 21, 2006I'm using SSIS to import data from a table (SQL) containing varchar fields. The problem is, that those varchar fields are changing over time (sometimes shrinking and sometimes expanding). I.e. from varchar(16) to varchar(20).
When I create my SSIS package, the package seem to store information about the length of each source-field. At runtime, if the field-length is larger then what the package expects an error is thown.
Is there anyway around this problem?
Oh, yeah... My destination fields are a lot wider then the source fields, so the problem is not that the varchar values doesn't fit in my destination table, but that the package expects the source to be smaller...

Date Problem : Dynamic SQL In An OLE DB Source Component
Feb 21, 2006Hello,
I have an OLEDB Source component with a Oracle OLEDB connection manager.
In my SQL statement I must do something like this ...
SELECT * FROM OracleTable
WHERE convert(datetime, OracleDate) = parameter
I've dynamicaly build the statement like this : http://blogs.conchango.com/jamiethomson/archive/2005/12/09/2480.aspx
Unfortunately this doesn't work because the variable is a datetime value and not a string.
Maybe another way is to store the date in a table in my SQL database and include it in my Oracle SQL statement ? This would mean that there are multiple connection managers being used in one SQL statement ... I have no idea if this would be possible ...
Any other options ?
Dynamic Source Table For SSIS Package
Oct 20, 2007I have created an SSIS package that is designed to move data from SQL Server 2000 to an Access db. I have set the package up to accept four parameters. They are:
the name of the SQL Server Database, which is used in an expression to provide the source connection manager connection string;
the full path to the Access db destination database which is used like #1 above.
the SELECT statement used in an OLE DB Source object to get the data from the source table
the table name which is used by an OLE DB Destination object.
I know that the source and destination tables have exactly the same structure and do not require a transformation.
In order to change variables 3 and 4 from above and have it work, I go through the following steps:
I change the variables to appropriate values.
Go to the Advanced Editor for the OLE DB Source object and click on "Refresh". This produces an error in the OLE DB Destination object that is something like "Validation error. Data Flow Task: DTS.Pipeline: input column "strRECTYPESUFFIX" (301) has lineage ID 17 that was not previously used in the Data Flow task.
Go to the Advanced Editor for the OLE DB Destination which brings up the "Restore Invalid Column Reference Editor". I mark all the columns that show up with the option to <Delete invalid column reference> and click OK
I then reopen the Advanced Editor for the OLE DB Destination, go to the 'Column Mappings' tab click 'Refresh', then in the upper pane where the input and output columns list appear I right click and choose "Map Items by Matching Names"
At this point I no longer have the error and the package will execute without any problems.
I am doing this so that I can load the SSIS package in VB.NET (2.0) so that I can then set these variables programmatically and then execute the package. The problem is that this actually performs steps 1 and 4 above. 2 and 3 are left out and the package fails miserably.
I have found some information that would be helpful if I could get my hands on the appropriate object. I realize that the data flow component would return VS_NEEDSNEWMETADATA from the Validate method, and that could be repaired with the ReinitializeMetaData method of the data flow component ( I assume that is the object to be using in this case). But I do not know how to grab the "Data Flow Component" as an object based upon the "Package" object I have loaded so that I can check if it is valid and manipulate it if necessary.
Thank you in advance for your help.

Dynamic Source For Excel File At Runtime
Aug 23, 2006Hi,
I've seen a number of posts similar to this but i still cannot figure out what i need to do to get it working. So here goes with a couple of newbie questions.
Question 1:
Once created how do i go about executing a SSIS package. I want to be able to call it from a C# application from which i pass in a couple of parameters?
Question 2:
How do i go about setting the file path of my Excel source to a dynamic value passed at runtime. I want to be able to loop through a number of Excel files and do some processing on them. I've set up a variable (which i think i need to do) after that i get stuck however. Some other posts suggest configuration packages but i cannot get my head around how they work?
Any help on this matter would be gratefully recieved.
Thanks in advance,

Dynamic OLE DB Table Source From Variable Not Seeing Input Columns
Dec 12, 2007I am building an SSIS package that loops through a table in SQL Server and dynamically builds a select statement that i would like to use as an ole db source. I have been having a difficult time with this as the select statement that i am generating is over 200,000 characters long so using an sql variable is out of the question.
I ended up placing the select statement into a table where each row of the table represents a piece of the select. I then use an execute_sql task that selects the entire rowset from this table into a variable object. I then use a for each loop to shred the variable and concatenate it into on big string variable called user:: sql_statement that is my select.
After setting up the loop and testing to see if the user:: sql_statement variable populates correctly i then added a data flow transfer with an ole db source and destination. I then go into the advanced editor for the source and set it to accept an sql statement from a variable and use my user:: sql_statement variable. I was forced to set validate external metadata option to false to avoid an error since there is no way to validate the columns until the for each loop runs during run time.
Now thats all fine and good but what is causing my problem is that during run time, when the package gets to the data flow task, the select statement doesn't seem to be populating the input columns of the data source. I have been searching to no avail on a way to tell the data source to update the input columns but every time it gets there, the package bombs out telling me the ole db source has no available output columns.
Specifically the error i get is :
[DTS.Pipeline] Error: "output "OLE DB Source Output" (6616)" contains no output columns. An asynchronous output must contain output columns.
Any help with this would be much appreciated.
Analysis :: Dynamic KPI Goal - Derive From Source Database
Jul 14, 2015I have a requirement to make all of my KPI goals configurable by the end user - I would like to add the data to my datawarehouse so that it is updated in the cube whenever the cube is processed. I'm thinking I will need a table for each KPI that includes two columns (I will be setting goal by year):
Year
Value
In my cube I then create a measure group for each KPI (for some I will add a calculations to break down the yearly goal to lower levels of detail).I will add each measure to my Dimension Usage and relate to each of my time dimensions at the Year level.I currently have around a dozen KPIs - my above approach seems a bit messy i.e. requiring a table and measure group for each KPI (I guess I could at least put them all into one table in my relational db).Â

Cannot Create A Connection To Data Source 'data Source Name'
Dec 11, 2007Today 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?

Loading Data Using Ole Db Source With Input Source Being A View
Dec 13, 2007I 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?

So entering a ProductIDshould not automatically enter the CategoryID also; whereasentering the ProductID should automatically enter its SupplierID.6-SOLDFROM, SOLDTO, MINSALES, MAXSALES, OPERATOR are mandatoryfields, you can't leave them NULL7-SupplierID, ProductID and CategoryID are the dynamic inputparameters, there can be 5 different combinations to choose from:a-SupplierID onlyb-SupplierID and a ProductID,c-SupplierID and a CategoryIDd-SupplierID, ProductID and a CategoryIDe-CategoryID onlyf-Any time you choose a ProductID, the SupplierID valuewill be filled automatically based on the ProductID'srelationshipg-Any of the three values here that is not chosen by theuser will take a default value of -1 (meaning return ALLfor this Column, in other words don't filter by this column)The major problem I have is I can't use dynamic SQL for choosingthe three dynamic columns as the 2nd row of records would have adifferent selection of dynamic columns (at least I don't know howif the solution is dynamic SQL). The only solution I can think oflooks pretty bad to me. I would use a cursor, run each row at atime, store a TRUE, FALSE value to stop processing or not andstore the result in another detail table. Then if all ANDquestions have ended with TRUE do a union of all the result andreturn the common list of employees. It sounds pretty awful as anapproach. I am hoping there's a simpler method for achieving this.Does anyone know if any SQL book has a topic on this type ofquery? If so I'll definitely buy the book.I appreciate any help you can provide.Thank you

Jun 1, 2015I have a requirement to take xml file, in case the number of column changes, it should not fail the package, rather it should load the data in destination table. Destination table could be altered separately depending on xml schema by the DB team in production.
