I 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.
View 3 RepliesThe only way to add a new column to an existing mapping that I know is to go to advanced editor and refresh. This however keeps only the default mapping (where the field names match), the rest is wiped out, so need to restore the mapping manually after that. Risky and annoying at the same time. Is there any alternative?

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,

Have to create SSIS package for the below requirement:
I have source data in 2 excel files. Data from both these excel files should be loaded to the same single Fact table.
The column names in excel files and table are not same. I have a Reference table which has the column mappings between excel and Fact Table.
I have to refer this Reference Tabel for column mappings, plus i have to add some derived columns (Created_Date) to load the Fact_Table.
I have given a sample data structure below:
Source Data
Excel1_Order.xls
OrderNumber OrderQuantity OrderDate
Order10001 100 01-01-2011
Excel2_Customer.xls
CustomerNumber CustomerName CustomerAddress
[Code] ....
Is there any way to handle this in SSIS?
How can I get table name and schema names of the source and destination in ssis package to insert into audit table....??

View 4 Replies View RelatedWe have a single generic SSIS package that is used to import several hundred iSeries tables into SQL. I am not looking to rewrite the process. But I am looking for ways to improve performance.
I have tried retain same connection, maximum insert commit size, lock table (tablock), removed some large columns, played with the log file location and size, and now I am working to tweak the defaultbuffermaxrows.
To describe the data flow task - there are six data flows tasks (dft) working at the same time. Each dtf has their own list of iSeries tables and columns and the corresponding generic SQL table names. Each dtf determines their list of tables based on the number of columns to import. So there is dft30 (iSeries table has 1-30 columns to import), dtf60 (iSeries table has 31-60 columns to import), etc. The destination SQL tables are generically called Staging30, Staging60, etc. Each column in the generic Staging tables are varchar(100). The dtfs are comprised of an OLE DB Source and an OLE DB Destination.
The OLE DB Source uses a SQL Command from Variable to build a SELECT statement. The OLE DB Source uses a connection manager that uses an IBM iAccess IBMDA400 provider. The SQL Command ends up looking like this for the dtf30. This specific example is importing from the iSeries table TDACLR and it only has two columns so it will be copied to the Staging30 table.
select TCREAS AS C1,TCDESC AS C2,0 AS C3,0 AS C4,0 AS C5,0 AS C6,0 AS C7,0 AS C8,0 AS C9,0 AS C10,0 AS C11,0 AS C12,0 AS C13,0 AS C14,0 AS C15,0 AS C16,0 AS C17,0 AS C18,0 AS C19,0 AS C20,0 AS C21,0 AS C22,0 AS C23,0 AS C24,0 AS C25,0 AS C26,0 AS C27,0 AS
C28,0 AS C29,0 AS C30,''TDACLR'' AS T0 from Store01.TDACLR
The OLD DB Source variable value looks like the following, but I am not showing the full 30 columns
select cast(0 AS varchar(100)) AS C1,cast(0 AS varchar(100)) AS C2,cast(0 AS varchar(100)) AS C3,cast(0 AS varchar(100)) AS C4,cast(0 AS varchar(100)) AS C5, ... cast(0 AS varchar(100)) AS C30.
The OLE DB Destination uses OpenRowSet Using FastLoad From Variable. The insert into Staging30 ends up looking like this.
insert bulk STAGE30([C1] varchar(100) ,[C2] varchar(100) ,[C3] varchar(100) ,[C4] varchar(100) ,[C5] varchar(100) , ... ,[C30] varchar(100) ,[T0] varchar(20)
Of course we then copy and transform the Staging30 data to the SQL table that equals T0.
But back to defaultbuffermaxrows. Previously the dtfs had default values of 10000 for DefaultBufferMaxRows and 10485760 for DefaultBufferSize. I added a SQL task to SUM the iSeries column sizes, TCREAS and TCDESC in this example, and set the DefaultBufferMaxRows by dividing the SUM of the columns max_length into 10485760. But I did not see a performance improvement. Do you think that redefining the columns as varchar(100) for the insert is significant? Should I possibly SUM the actual number of columns (2) as 2x100 or SUM the 30x100?
1 How to get the desired output colums into Excel file without having 'copy of column/unwanted columns' in destination file.
2. How to override the existing file in excel destination.
can somebody show an example of how to map source and destination columns when uploading a file to sql server?
Also, please send me the mapping when i want to map source to different destination columns.
I am in between of creating a dynamic SSSIS package which will run for multiple zones having different source connection.My source is in Oracle.I am having 3 DFT with the 3 different source tables.I want to create a package with above DFT dynamically so that my single package can run for the entire zone with dynamically source connection change.I have created a Master table which stores the zone source connection string and zone name. I have 2 different connection.so if in future any new zones come so only newly zone details need to be add in master table without opening the package.

and Fact table like
fact_key persn_key units_purchased

persn_key is the surrogate key between tables.
My question here is as the dimension has SCD type 2 on it and every time when there is a change the persn_key gets a new key value but the fact table still points to oldest key.how to update the surrogate key on fact table to the current key value? As per the requirement fact surrogate key must be pointing to current active record on the dimension.
Need to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
@[User::Output_Path] + "Comms_File"+ @[User:: FileNumber] +"_" + replace((DT_WSTR, 10) (DT_DBDATE) GETDATE(),"-","")+ ".txt"
All this successfully creates these 4 files:
Comms_File_1_20150724.txt, Comms_File_2_20150724.txt, Comms_File_3_20150724.txt, Comms_File_4_20150724.txt
Now the QUESTION is how do I get these filenames as I need to insert them into a DB Audittable. The audit table looks like this:
CREATE TABLE dbo.MMMAudit
(
AuditID INT IDENTITY(1, 1) NOT NULL,
PackageName VARCHAR(100) NULL,
FileName VARCHAR(100) NULL,
LoadTime DATETIME NULL,
NumberofRecords INT NULL
)
To save the Filename & how many records in each file in our Audit Table, am using an Execute SQL Task and configuring it as this:
Execute SQL Task
Parameter mapping - Mapped the User Variable (RecordsInserted) and System Variable( PackageName) to Insert statement as shown below
SQLStatement: INSERT INTO [dbo].[MMMAudit] (
PackageName,NumerofRecords,LoadTime)
(?,?.GETDATE)
Again this all works terrific & populates the dbo.MMMAudit table as shown below BUT I also need to insert the respsctive file name – How do I do that?
AuditID PackageName FileName NumberOfRecords
1 MMM NULL 12
2 MMM NULL 23
3 MMM NULL 14
4 MMM NULL 1
How do I add only new rows to a destination table (when copying a table from another database every night) ?Every night I am copying a number of tables from one database to another.I only want to insert news rows (that are not in the destination table, but are in the source table) to the destination table.I might normally drop the destination table and just copy over the whole table, but in this case rows can be deleted from the source table, but I want to keep these old rows in the destination table (to maintain history). So I only want to add in rows to the destination table that have been added to the source table since last time.I guess I could copy the whole of the source table to a temporary table in the warehouse, then use a T-SQL merge command to compare and just add new rows to the destination table- but suspect that this is not the best way.

View 7 Replies View RelatedI have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables.
* Get last 3 months data from source table.
* Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.
Hi,
I am building SSIS for 3 different files that have identical
schema and mapping logic.
In my OLE DB Source (object name - "OLEDBSource_SourceTable")
Data Access mode is "Variable name".
As soon as I swithced to this Data Acces mode
it started to give me an error:
[OLEDBSource_SourceTable [1]] Warning: The external metadata column collection is out of synchronization
with the data source columns.
The column "DEAL_NUM" needs to be updated in the external metadata column collection.
The "external metadata column "DEAL_NUM_Flag" (34529)" needs to be removed

I 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

Is there a recommended file format (csv, xml, txt) when choosing a file destination for SSIS? Does a file format impact the performance in terms of loading?

View 3 Replies View RelatedI have a table is SQL server database A that is my source. I have another database B which is accessed via webservice call.(its a CRM server basically). My intention is to transfer data from A to B while B is accessible only via web service. I need to update existing one and create the missing one.
Currently I am using script component, and on every insertion of a row, i call the webservice to check if the record exist or not. If it exist I update it else create it using webservice call itself.
All this happen in Input0_ProcessInputRow(Input0Buffer Row) function.
Now this method is making 2n webserive call which is making the performance very slow.
I want to optimize the approach. Is there a way where I can retrieve whole set of rows in source table in preexecute(), filter it and store it in a List. This way, i just need to check the list a perform update ro create accordingly preventing my webservice call.
How to optimize this or even some better approach?

I have requirement to update/insert the DPID based on the address which are passed as an input values.There are more than one address at the same time and I configured to get the address from the query which are correct and output of the address values will be stored as system object variable.I am then passing the system object variable to for each loop container and I have configured the collection and variable mappings as a variable for each input value.
when I pass the value manually to the web service task it works correctly.When I pass it as a variable to web service task it doesn't return any value.I have a data flow task which converts the ouput from web service task using the xml source converts it to oledb destination.I don't see any rows being written to the target table.
