I'm trying to conditionally execute a dataflow based on the presence of a data file. If the data file isn't present, I'd like to execute gracefully without error.
Logic is as follows:
If FileExists Then execute dataflow Else exit w/o error End If
I've got the code ready to go, but I'm not sure how to do this conditional branch logic. Right now, the code calls the Dts.Results.Success / Failure. The problem, however, is Failure is exactly that... which doesn't result in the graceful exit I'm looking for.
I have Variable , data source and conditional transformation which checks the count(*) if the count == 0 then I connect an script component and change variable to false(initial it is True) and write into a log file...
Then I check that variable on predence constarint at workflow if variable==True then success. BUT Whenever I run the package my dataflow gets green even the condition does not meet like count==0 . So my variable's value is "False". Actually if the condition doesnt meet then my script shouldnt work. Am I missing something???
I have two connections in a package pointing to two different databases on the same server. I have to insert records from 'DB1' table 'Gender1' to 'DB2' table 'Gender2'. Before I do that though, I have to make sure the minimum value (of all the Gender Keys that are going to be inserted) of 'DB1' 'GenderKey' (which is an identity field) is greater than the maximum value of DB2-GenderKey (which is a primary key but not an identity field). How can I do this simple check? I have to do this process for many different tables ....... Gender table is just an example. If someone can give an detailed explanation on which tasks to use and how to use them (as I am relatively new to SSIS) that'd be great.
If DTSGlobalVariables("gsPrevProcessCount").Value > 0 Then MsgBox "The data for one or more of your members has already been processed. Please review your data files and remove the processed files from the data directory." Main = DTSTaskExecResult_Failure Else Main = DTSTaskExecResult_Success End If
In SSIS, I have an Execute SQL Task that returns a variable PrevProcessedCount. Now, I am stuck. How do I display a message to the user (or maybe just put it in the audit log) and how to I check the variable and stop processing my package?
First post here. Anyway, I have a question regarding SSIS. I'm currently given a task that requires reading a flat file, applying duplicate removal as well as invalid data removal, processing it, and finally writing it to a SQL Server 2005 DB.
Part of the processing requires checking for partial duplicates in the batches of records provided in the text file. For example, the record contains a a phone number, status, timestamp of creation and various other entries. If a phone number is repeated (meaning, duplicate entry), a column called 'Status' must be checked, and only entries with the status of 'C' is allowed through.
Another part of the processing requires that if the phone number is repeated along with various other entries including status, the timestamp of creation is checked and only the entry with the most recent timestamp is accepted.
I would like to know how to implement this in SSIS without using table objects and scripts, as my experience tells me that doing this in a script can really take a hit on system performance. The task is expected to handle tens of thousands of records in a day.
I am having a hard time with what appears to be something simple. I want to import an excel spreadsheet into a table on a daily basis from a command line. I created a package from the Import Wizzard in the SQL Management Studio and saved it. Since I want a clean table each day, my process needs to be create a temp table, import from the Excel file into the temp table. If that is successful, delete the original table and rename the temp table the original name. The point of this process is to provide for a fail-safe if there is some unforseen problem downloading the data on a particular day.
When I run the package, the first thing it does is delete the original table. I know this because the process shows the time that it finished is before anything else has started or finished. The time shown for the completion of the data flow task is about 2 minutes after that time.
This is maddening!!! The one thing I do not want to happen I can not seem to prevent. I have my control flow set on success. Why does it do this?
HI, How to create package in SSIS by applying the business Logic like if the record already exist it should be and update else it should be an insert in the destination table. how to achive this funcality in SQL SERVER 2005 (Business Intelligence studion).
There is a table with a column that contains Xml documents. For each record from my Data Flow Source, I want to pass in the Xml document and the node to interrogate, and return the value contained in the node. Like the Crm component, this is probably one I will have to write from scratch in C#, but I would like to avoid having to create the custom component if it already exists in the public arena.
Does anyone know of any Xml Ssis Data Flow Components that are downloadable for free?
I was working all day making changes to my 3MB package. I was adding a large number of transforms that were copied-and-pasted from elsewhere in the same data flow task.
All was going well. I even took the time to have SSIS lay out the task again (1/2 hour). Suddenly I started receiving some strange errors:
After the layout, I noticed two stray components 'way off in the upper right corner. I found that one of them had a duplicate name to a component which had been added hours ago. Even after deleting it, I got "duplicate name" errors.
I copied three components in one selection, and when I tried to paste them, got the error "can't initialize component on paste". I tried them one at a time, but got the same error.
I got errors about COM failures due to marshalling to another thread I then exited Visual Studio and started it again. To my great surprise, the data flow task I was working on was still there, but was completely empty.
Comparing what I'm left with to my last version in source control, I find that the entire pipeline element is missing from the DTS: ObjectData element!
I'm developing a real love/hate relationship with SSIS. It varies from one day to the next. Guess what kind of day this is!
Can anybody help me out in 1) implementing cursors in SSIS. I want to process each row at a time from a dataset. I was trying to use Foreachloop container but in vain. Can you please answer in detail.
my few other questions are: 1) Can i do nested inner join in SSIS. If yes, how? ( I have three table i need to join Tab1 to table 2 and get join the table 3 to get the respective data) 2) I have a resultsets. I want to split the data according to data in a col. Say for instance: Col1 Col2 A 1 A 2 B 3 C 4 C 5 i want to split the data according A, B and C . i.e., if Col1= A then do this, if Col1= B then do this..etc. How can i do this using conditional split task in SSIS
I am using SSIS in SQL Server 2005 and want to have a query like this in my data flow task
Select a.* from abc as a inner join (Select max(b.id) as ID from xyz as b inner join pqr as c on b.id = c.id and b.id > ?) as t1 on t1.id = a.id
SSIS fails to detect the parameter (?) for the inner query and gives message.
" Parameters cannot be extracted from the SQL command. The provider might not help to parse parameter information from the command. In that case, use the "SQL command from variable" access mode, in which the entire SQL command is stored in a variable.", so assuming this is your problem, then you can workaround.
The idea is to parameterize the inner query ,,, (so if the above query doesnt make sense ignore it )
I am having some problems with the loading of tab delimited text file (source) to a SQL Server table (destination) using the SSIS data flow task. Package has been executed successfully with no error msg. The number of rows in the text file also matches the number of rows in the SQL table. But, when I check the content of the table, I noticed some of the columns contain NULL which supposed to have value. This happens not to all the rows but only to some rows. I did some testing by removing some rows from the beginning, middle and end of the text file and re-run the package but the result is quite inconsistent. Sometimes, the field got filled, but sometimes, it just contains NULL where it supposed to have value.
I am experiencing an error where the ssis data flow task would freeze and stop data export from a oledb source to a text file. It doesn't generate any errors the ssis package would just hang. This only happens when I run it in 64 bit mode. When I change the mode to 32 bit the ssis never freezes and runs fine. Has anyone experience this? Is there a fix so I can run my jobs in 64 bit mode?
I have a SSIS Package which I would like to modify using SSIS API. I need to put new component between some two existing data flow's components. During this process I need to disconnect two data flow's components using SSIS API. How can I do that?
I am loading a lot of Excel and CSV files to SQL Server. Some loading may fail for various reasons. I want a file either be load as a whole or nothing. Currently I keep a list of failed filename and remove it at the end (I add a column for source file name).
Any better way to make sure a file is loaded as a whole or nothing?
I would like to know how I can add the following sample code to my Source data on Data Flow on SSIS, or what other options there are. The main issue is time as we have talking about 100's of millions of rows
select Sample, CASE WHEN Sample IS NULL THEN NULL WHEN SUBSTRING(Sample, 1, 6) IS NULL THEN ' ' ELSE RTRIM(SUBSTRING(Sample, 1, 6)) END AS [Sample_1_6] from TestTable
what I have done at this stage is just to Create a SQL task with a Insert into
INSERT INTO [dbo].[TestTable1] ([Sample] ,[Sample_1_6]) select Sample, CASE WHEN Sample IS NULL =THEN NULL WHEN SUBSTRING(Sample, 1, 6) IS NULL THEN ' ' ELSE RTRIM(SUBSTRING(Sample, 1, 6)) END AS [Sample_1_6] from TestTable
If there is a way adding this to a dataflow so I van use fast load that would really be the best solution. I know there are derived columns, but would this really be faster than the straight insert into in a SQL Task? If this is the way to go what is the code I would use in the derived column or any other option.
Hi All, Just needed an insight into the IF-ELSE construct w.r.t its implementation in SSIS or a similar methodology that could be adopted in SSIS while executing a Package.
Scenario : I want to Start with importing data from Different sources to SQL Server Destination. For Which, i define 3 different Data Flow Tasks each involved in importing data from an external source to SQL Server Destination.
1] Text File Inbound Task : Source - Flat File Source ; Destination - SQL Server Dest. 2] Excel Inbound Task : Source - Excel Data Source ; Destination - SQL Server Dest. 3] Xml Inbound Task : Source - XML Data Source ; Destination - SQL Server Dest
Finally i want to execute the package with an IF-ELSE Scenario which will Check for the external Source being :
I have a relatively simple SSIS package that I'm building for a data mining process. The package starts with an OLE DB data source, passes the results of a SQL Command (query) along to a conversion step, which then gets sent to a Term Lookup task. The Term Lookup then writes the result to an OLE DB Data Destination. Pretty simple. The OLE DB data source query returns about 80,000 rows if you run it through SQL WB. The SSIS editor shows 9,557 rows make it out of the source, and into the conversion step, 9,557 make it out of the conversion and into the lookup, and about 60,000 rows make it out of the lookup and are written to the results table. Then the package fails with the following errors listed on the progress screen. I was assuming that the 9,557 was some type of batching that was occurring in the process, but now I'm not so sure.

I have a package that loads staging tables from an Oracle source DB. In the data flow tab I have 30+ read table/write table task combinations. When I run the package 3-4 of the read/write combos execute at a time. What I'm trying to control is the priority order of the combo execution. My goal is to minimize to total load time by having the larger table transfers run first and the smaller table transfers fill in until they are all complete. Currently, the largest table (16 million) transfers last (because it was the last combo that I created?).
I am creating a staging database in which I am loading required tables from 2 different sources. I have 30 different tables to load from source 1 and 10 different tables from source 2. This is the way I am doing, in Control flow task I am using Sequence container and in that I included the data flow task, the data flow task has source OLD DB connection from where I select the table and then destination OLE DB connection where I load the data. So for 30 tables I have one Sequence container with 30 different data flow task and each data flow task has OLE DB source and OLD DB destination. I wanted to find out if this is the efficient way to do, or if there is any other way to do this. And for source 2 shall I put in another package or shall I use the same package with different sequence container and follow the same steps as for Source 1 tables. Please advice. Thanks,
Has anyone come up/determined a generic way to capture and log indicative information within a data flow in SSIS - e.g., a number of rows selected from the source, transformed, rejected, loaded, various timestamps around these events, etc.? I am trying to avoid having to build a custom solution for each of the packages that I will have (of which there will be dozens). Ideally, I'd like to have some sort of a generic component (such as a custom transformation) that will hide the implementation details and provide a generic interface to the package.
It is not too difficult to achieve something similar on the control flow level, but once you get into data flows things get complicated.
Is there documentation somewhere about multiple execution paths in SSIS control flow? I didn't find documentation anywhere. I have a situation where I have two tasks that take considerable time, but could be executed in parallel (to speed up things) and I was wondering whether SSIS supports parallelism.
To illustrate the issues in simultaneous execution, I created a test SSIS package. In the package, I have five tasks, let's call them T1, T2, T3, T4 and T5. The taks are connected with "green arrows" like this:
T5 is not connected. The tasks can be e.g. Send Mail tasks, that's not relevant to this issue. I put a breakpoint in each task and execute the package.
When I execute package, T1 and T5 become active, i.e. the arrow that displays where the package execution currently is, is in two tasks simultaneously. Now F10 (step over) doesn't seem to work "Unable to step. Not implemented". If I press F5 nothing happens. After I press F5 for a second time tasks T1 and T5 and executed. Why don't they execute with the first pressing of F5? I would additionally like to know whether these two tasks are executed in parallel or sequentially, i.e. in the same thread or in two threads? Is there documentation of this?
The execution stops at T2&T3. Again, pressing F5 doesn't do anything, but the second time I press F5 T2 and T3 are executed.
