My Requirement is Update Table 1 set Column::No=Table 2.ID
based on Exact Match of
Table1.Name=Table2.Name and
Table1.Add=Table2.Add
It means Get back the Id for Source Table 1
2nd Data flow
Source(Table1:Name, Add,No)
|
--LOOKUP(Table2:Name, Add::Matched Look Columns Name, Add and
Tick Mark on ID)
|(Match)
-->OLEDB Command: update Table1 set N0=? where RowID=?(Here Param_0= NO ,Param_1=RowID)
Here My Issue is if Table 1 had Duplicates(same Name, Add, but Row Id is different it is Updating Same ID for Table 1.No It means Get Back ID correctly not updating Result::
Table 1:
------- ----- ---- ----
Name Add No RowID
------- ----- ---- -------
aa #a-1,India 1 10
bb #a-1,India 2 11
aa #a-1,India 1 12
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
I'm trying to insert records into "holding" table and write back identity column value (Entry_Key) to the original table. So my setup is I have two tables; tblEWPBulk and tbleFormsUploadEWP. Users will enter records into tblEWPBulk and use BatchID to group records, once batch entry has been completed (usually less than 30 records) user will click on UploadAll button and insert records (not all fields) into tbleFormsUploadEWP. One record in tblEWPBulk can be sent multiple times to the holding table but tblEWPBulk will need to have latest Entry_Key captured. Records are sent from holding table to DB2 z/VSE using SQL stored procedure and based on certain logic records are marked uploaded or certain error capture... that part works fine.
So for example I want to send
BatchID, AccountNumber, Period, ReceiveDate, AccountType, ReturnType, NetProfitOrLoss, TaxCredit FROM tblEWPBulk to the holding table and write back Entry_Key (identity column) back to the record in tblEWPBulk (field called UploadEntryKey). As I said one record could be sent to the holding table multiple times until uploaded or deleted and UploadEntryKey always needs to be updated so that when results are processed response from the DB2 can be inserted into table and presented to the user.
No foreign key relationship exists since records in the holding table get sent to the archive table and table is truncated and entry_key starting value reset back to 2000... just some DB2 restrictions.
I am looking for a way to leave a Data Flow Task destination table name as-is, and have SSIS auto-create the table if it doesn't exist already.
I searched on this in the forums but based on the question it's difficult to kow if it has been answered or not.
Details:
I am writing some SSIS packages that need to be executable on another server. Many of the Data Flow Tasks copy data (such as from a Fuzzy Grouping transformation, and lots of other stuff) into a new table. But the other server will not have these tables set up for the first run.
My current solution is to check information_schema.tables and drop IF EXISTS. But, then the Data Flow Task will not work (becase table does not exist). So, I script to new window a create table statement based on the existing table that I use in my dev environment. This is a hack and I want to find a better method.
It is quite possible (although unlikely) that the source columns could be changed in the future, or some query used to pull the data might be modified. If this happens, then I would need to change the CREATE TABLE Execute SQL task. I want my package to accommodate without having to modify it.
When I use the Import/Export Wizard, I can select a table name from the drop down list OR type in a new name. When I type in the new name, it assumes I want to create the table. NOW, is there a way to mimic this in BI Developer Studio? Yep, I saved the Wizard version of the SSIS package and all it does is run a CREATE TABLE statement first.

Hi, I use lookups to map surrogate of level 1 dimensions to my fact tables in SSIS. But how to handle a level 2 dimension with a ValidFrom and a ValidUntil date field? I do not use an IsCurrent column, because this could problem with late arriving facts.
- In dts I used an SQL statement like this:
update SA SET SA.DimProdRef = Dim.RecordID FROM SAWarenEingang SA, DimProd Dim where SA.ProduktNumber = Dim.ProduktNumber and SA.ArtikelkontoBewegungsdatum between Dim.ValidFrom and Dim.ValidUntil
Now in SSIS I want to handle the whole thing in the data flow without using a staging table: - Using Lookups: I would have to pass the date column for each inside the fact table into the lookup. That does not work. - Using Execute SQL in the data flow: would be very slow, because the statement will be executed for any line in the dataflow
We have created SSIS package to load a text file into a table. Source system shares 10 text files and recently they stopped generating data for one of the text file (comping empty), after few months they will start generating the data for the empty file batch processing.
The Issue here is Data Flow task is getting failed while loading empty text file into table. How to handle this empty file load issue in SSIS package.
I'll preface this by saying I'm pretty new to SSIS; I'm coming over from Coldfusion and don't have much DTS experience to draw from either. That said....
I've got a package that I run to migrate data from a bunch of older databases into a "flat" new schema. The new schema is not identical to the old, in other words, so it's not a simple mapping of existing columns. All the data flow tasks have finally gotten to a working state, with much trial-and-error. Now, suddenly one of the tasks is throwing this error: "...Cannot insert the value NULL into column 'the_id', table 'the_table'; column does not allow nulls. INSERT fails."
The column is an identity column in the new table; it is NOT NULL as it is the primary key. I've triple-checked that identity is on. Basically it's generated anew each time this package is run. In the data flow task, mappings are set to ignore for this column; also, Keep identity and Keep nulls are on (although since this column is not in the source I can't see how this affects anything.)
(***For anyone wondering why in the heck I'd need this column at all, offhand I can't recall if later tasks use it or not...I'm actually wondering if it's even needed in this read-only table if it's not used as a foreign key somewhere else...however, I'd like to figure out this issue regardless... )
I've had a hard time finding anyone with the same problem out there...usually people with NULL issues simply are trying to insert into a NOT NULL column. The big difference here is that the column is identity.
I need to see inside a SSIS 2012 project a new SSIS installed component, but in the SSDT 2010 I cannot see the SSIS Data Flow Items tab for adding data source/data destination respect to the choose toolbox items pane.
I need to call a stored procedure to insert data into a table in SQL Server from SSIS data flow task. I am currently trying to use OLe Db Destination, but I am not sure how to map inputs to OLE DB Destination to my stored procedure insert. Thanks
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!
I have a table of raw data where each column can be null. The thought was to create an identity key (1,1) and set as primary for each row. (name/ address / zip/country/joindate/spending) with surrogate key: "pkid".However other queries will not use this primary key. So for instance they may count the # of folks at a zip, select all names, addresses etc. The queries may order by join date, or select all the people that joined on a specific date.No other code would logically use the primary key (surrogate primary id key), therefore would it still have any performance benefits? at this time the table would have no clustured or nonclustured indexes or keys. I'm curious if there are millions of records.
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.
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.
Thoughts?

Does anyone have a helpful link for using the partition processing data flow task in SSIS? I am trying to process a monthly partition from within my package and am getting the following error:
Error: 0xC113000A Errors in the high-level relational engine. Pipeline processing can only reference a single table in the data source view.
If anyone has used this before and could point me in the right direction, I would appreciate it.
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.
I'm creating a SSIS in the designer view of SQL Server BI Dev. Studio (SQL Server 2005)
I need to import a whole table from MS Access into my local SQL Server.(this task will be performed weekly, so once working I'll schedule a job for it)
I've created a 'FILE' connection to MS Access in the 'Connection Managers'.
When I'm on the 'Data Flow' tab I can't find a Data Flow Item to use as a MS Access connection. (available on the 'Data Flow Sources' are only: DataReader, Excel, Flat File, OLE DB, Raw File and XML Sources)
I am using the "SSIS Log Provider for SQL Server" to log events to a table for "OnError" and "OnPostExecute" events of a package. This works as expected and provides a nice clean output on the execution steps of the package.
I am curious as to why I do not see any detail for any/all tasks that fall under the "Data Flow" section of the package though. For instance, on my "Control Flow" tab, I added a "Data Flow" task that simply loads a few tables from a target to destination server. However, there is nothing shown in the logging output. Just that a Data Flow task was initiated. And when I'm configuring this logging under "SSIS-->Logging" in the checkbox area on the left, you cannot "drill into" data flow steps.
Is there a reason why there is no detailed logging for Data Flow tasks? Would getting to that require me to create a custom log provider?
