Integration Services :: How To Implement SCD For No Unique Columns In A Table
May 11, 2015
I would like to know what is the use of business key? Is it necessary to have unique key between source and destination? If no, How can we implement SCD?
PS : My source is CSV files and Destination is Oracle DB?
I 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.
I have a requirement of migrating DTS package which is done in Sql Server 2000 to SSIS 2012.
I started with one package having data driven query task and done with source for which i chose OLE DB Source and given the required select query in ssis 2012
I'm stuck now and i'm unable to choose the relevant tools in ssis 2012 for binding, transformation,queries and lookup tabs used in dts 2000 for this DDQT.
The 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?
In order to update an Oracle table target from a SQL Server table source I need to use a Foreach Loop Container, so I can loop on the rows of the SQL Server table source. This source table has two columns: the old identifier to update and the new identifier to apply. I must use the value of the old identifier to filter the Oracle rows to update, while the new identifier is the new value to assign to the filtered old identifier.
I already know how to use the Foreach Loop Container when it is necessary to loop on an unique column of a table/view (using an object variable, using a Foreach ADO enumerator, etc.), but I need to loop on two columns.
I have a look up table with old data, which i need to truncate and load with the new set of data, however when loading I'm getting the following error
[OLE DB Destination [32]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80004005 Description: "Cannot insert duplicate key row in object 'dbo.CaseType' with unique index 'idx_CaseType'. The duplicate key value is (49, AH).".
I know , what it means that since CaseType column has a unique index we cannot insert duplicate key, but in real world the scenarios are different , the record in question is as follows: so what is the workaround in this kind of scenario other than making it Non-unique Index?
I have one table which is using to keep 10 difference type of serial number (that mean i got 10 column in the table). Is there any way to do unique key checking (individually, not combine) on these 10 serial number without sacrify the performance?
Hi,I would like to add a unique index that consists of two fields in atable.e.g. tbl_A (field1,field2) -- field1 & field2 Indexed and combinationmust be Unique.Can anyone tell me the actual sql syntax to create this index?Thanks,June.
I will be receiving a CSV daily where columns within the file will change. The column order and number of columns can change daily. I need a way to read in the header from the csv and create a flat file connection that reflects the columns listed in the header.
Is there an easy way to do this using a script task? I have already read the header into a table but I have been unable to create the dynamic file connection.
I have a situation where i need to unpivot multiple columns using ssis. The data looks like
Name Age products1 products2 orders1 orders2 abc 23 cycle radio 12 24 as Name Age Products orders abc 23 cycle 12 abc 23 radio 24
Is it possible to do this using the unpivot task in ssisMy actual data is has 18 columns which needed to be unpivoted into one and another 18 into another one.when using unpivot task it gives an error saying only one pivotvalue key is allowed.
I have a lot of different data flows that need "Derived Column". There are maybe only 5 different such "Derived Column" but they appear many times. Is there a way to eliminate all that double work? It should be something that does not take me more time to do than just duplicating all the "Derived Columns".
I am new to SSIS and C#. In SQL Server 2008 I am importing data from a .csv file. Now I have the columns dynamic. They can be around 22 columns (some times more or less). I created a staging table with 25 columns and import data into it. In essence each flat file that I import has different number of columns. They are all properly formatted only. My task is to import all the rows from a .csv flat file including the headers. I want to put this in a job so I can import multiple files into the table daily.
So inside a for each loop I have a data flow task within which I have a script component. I came up(research online) with the C# code below but I get error:Index was outside the bounds of the array.I tried to find the cause using MessageBox and I found it is reading the first line and the index is going outside the bounds of the array after the first line.
My File1Conn is the flat file connection instead I want to read it directly from a variable User::FileName

I have an Integration services application that retrieves big strings (over 32k) from an ODBC data source and stores them in a SQL server 2005 database as ntext. Somehow the strings are truncated to 32K. The app only copies the data from the ODBC datasource to the (OLEDB) target. Also, some of the special characters in the input text are not properly translated.
I am looking to create a script that will go through a table a pick out the necessary columns to create a unique record. Some of the tables that I am working with have 200 plus columns and I am not sure if I would have to list every column name in the script or if they could be dynamically referenced. I am working with a SQL server that has little next to no documentation and everytime I type to mere some tables, I get too many rows back.
Is there any way to do things with filesystem in SQL 2005 ? I want to check a file and if exists I could replace data into it or create the file if not exists. I tried build a DLL file using C# to do those things and registered it in SQL 2005 but when I execute the procedure it returns an error like this below :
Msg 6522, Level 16, State 1, Procedure testfsq, Line 0A .NET Framework error occurred during execution of user-defined routine or aggregate "testfsq": System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.System.Security.SecurityException: at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.IO.FileInfo..ctor(String fileName) at FSQuery.fsq()
So, is that means that we can't use another namespace in .NET framework but Microsoft.SQLServer.Server ? thanks in advance.
I have to load on SS2012 hundeds of excel files produced by an application over the last five years, during time few columns have been added to the initial set.I created on SS2012 a table to match with the full set of columns and want to load all the files inside the table leaving the missing cells to NULL. I think SSIS can do the job but every trial failed do far.
I have to transform 500 columns from an excel sheet to Sql Server. In Excel 2k3 , I can read a max of 256 columns only.If I use Excel 2k7, then SSIS 2k5 excel source does not support excel 2k7. If I use ole db source then again it can read a max of 256 columns.how can we read 500 columns in excel sheet (Around 10000 rows) efficiently using SSIS 2k5.
In SSIS I use the DQS Cleansing transformation component. I've got a knowledge base (KB) in place and this KB holds various domains and my data source has more input columns than would like to use for a particular clean up operation. I want to use some of the input columns to map against some domains in the KB. It is my understanding that it should be possible to select only the required input columns, but all i can do is select all input columns.
In ssis i am using ado.net and selecting odbc driver i am giving select statement which is having 100 columns in that 50 columns values are NULLS Its giving error saying Null columns not found.
If i add column s which are non null no error .error with null values.
We have a requirement to produce adhoc Excel reports with a standardized header page with a disclaimer attached. We want to be able to feed in a SQL Statement, or a table with the resultset from a SQL Statement and have SSIS populate an existing blank Excel workbook, which the disclaimer attached. The use of xp_cmdshell is not an option.I've spent a lot of time looking for solutions on the web and it seems though its not possible - although many articles are 3-5 years old. Before I throw in the towel, I just wanted to get feedback from this group if it still is not possible in the latest versions of SQLServer and SSIS, or to ask if there are any other 3rd party solutions that can do this today.
I was to split each record into multiple columns. The problem is some records need to be split into only 1 column, others may need to be split into more. Also need to remove the "/"'s. This is all dependent on where a "/" is found. Been beating my head for a while and getting nowhere.
So:
create table #foo (myPK int, c1 nvarchar(425)) insert into #foo values (1,'/folder1') insert into #foo values (2,'/lvl1/folder2') insert into #foo values (3,'/folder1/lvl2/folder3') insert into #foo values (4,'/f1/folder2/lvl3/fldr4')
I have a scenario where we have to handle dynamically changing source columns.
For example , some times in the source files the number of columns will be increased or decreased, new columns can be added in the middle or in the end of the source file.
I have a requirement wherein I have to setup the flat file connection manager to accept columns on fly. Meaning I want to retrieve list of columns/column count from the database when the package is run and set the connection manager with those many columns.
I've created a SSIS package which takes a matrix from Excel file and insert into SQL table. It works perfectly! However, if I would add a new column into that matrix in Excel. Unpivot tool should take into process dynamically. Is there a way to provide this automatically?
I have a situation where I want to load the Excel file dynamically, and the excel file have different columns or even worksheet name. How I could approach this? I believe there's no way to modify the meta data (specifically the mapping) in the data flow.
I want to load flat files into a single table. But the flat files can have variable number of columns upto a maximum of 10 columns. The table in my database has 10 columns in it. So in case if I load a flat file having 6 columns then rest of the columns in the table will have nulls. I don't want to use script task for this as I am not good in writing C#code.
I'm trying to use the Import/Export Wizard as I used to, as a handy tool to figure out what a series of T-SQL statements (in an SSIS package) is doing - or, if I'm lucky, what on earth the original dev intended them to do.
Version: SQL 2014 64-bit running on Win 7 64-bit
The code is pretty dreadful:
SELECT DISTINCT on one set of column names, join this set to another table but not on exactly the same set of column names, embedded (SELECT MAX(bla) FROM SameTable WHERE [match to outer set on another set of columns] GROUP BY [hey, yet another set of columns!]) inside the SELECT column list... and it all goes to a nasty #Tmp, which is then abused with further bad code further down.
Imp/Exp is always handy to quickly get the intermediate results into an auto-created real table, so I can figure out exactly what the effect of this is. I use it to export from the database back to the same database, but to a persisted table.
This time (first time with SQL2014) it's not working. The source is "write a query" (paste the actual query). The destination I set to a new table. The auto-generation of the new table creates every column as type date. Not surprisingly, this doesn't work, as the original data is mostly not of date time.
I am new to MDM profisee tool and currently working for Addres verification project for my organization.I wanted to clear my doubts here about Unique Identifer in Stage table and how it works.. Here what i understand till now:
Step 1) I created an Entity using MDM profisee UI and it generated a stage table in MDS database called stg.Address_leaf Step 2) I have loaded data from external source to MDS stage table using ETL and passed Import type as 2 and Import status id as 0 Step 3) I have run store procudure system generated something stg.udp_Address_leaf to load the model and passed the version name as Version_1, Log flag as '1' and Batch tag as 'Address'
Now my below are my questions: 1) What is the field i can use in MDS stage table to populate my unique intifier value coming from source? (lets say Address_Id is my Unique value for all the records coming from source) 2) Where/how Unique Identifier is useful in this process? Will this be useful in next time load from stage to Model? 3) If i truncate and load my MDS stage table in next run and few earlier records has been updated how it will update those records in Model? will this process (code present in SP) recognize by Unique Identier column present in MDS stage table?
