Moving New Data Into Dimension Tables Automatically Using Integration Services
Jul 25, 2006
I have an Integration Services package that loads new data into tables that are dimension tables wi my cube. The same situation exists for my fact table. If I perform an "Analysis Services Processing Task" for the dimensions ,cube and measures, will that move the new data into my cube or do I need to perform the "Dimension Processing Destination" data flow task prior to this? Is the initial processing task good enough?
thx,
-Marilyn

I have a requirement to compare data between two tables in SQL Server.
What is the fastest way to do it using SSIS? There are approx 6~7 millions of records in each table.
My solution: Read both the tables and store the data in Object Type variable. Then run an except query. But I am stuck at except query part. How do I implement it?

I am going to set up a new SSIS package that will import data into 5 different tables on a SQL Server database. The source of the data is on another SQL Server and I will use to select the data. If one of the tables fail to import I do not want the SSIS package to import any of the data.What is the best way to create this package? Is it best to create one SSIS package, with five data flow tasks that are linked to each other. Within each data flow task, is a Source and Destination to transfer the data to each table.

I would like to export all tables from Oracle 11.2 to MS SQL Server 2012 R1.
Using the tool "Microsoft SQL Server Migration Assistant v6.0 for Oracle" did not work for me because there are too many warnings and errors regarding the schema creation (MS cannot know it because they are not the schema designer). My idea is to leave/skip the schema creation to the application designer/supplier and instead concentrate on the Oracle data export and MS SQL data import.
What is the easiest way to export all tables data from Oracle to MS SQL Server quickly?
Is it:
- the „MS SQL Import and Export Data“ Tool
- the “MS SQL Integration Services” Tool
- not Oracle dump *.dmp format because it is a propritery binary format
- flat file *.csv (delimited format)

I am trying to move data from 8 different tables that are dependent on each other through foreign key relationship.
Basically they have millions of rows in each table and they have data for the past 5 years. I want to move data for the past 120 days and move it to 8 new tables in the same database. So I created the new tables along with their relationships. Now I need to move in the order (parent table first).
The child table has 50million rows data to move
The intermediate tables have 10 mil 10mil 10mil and 40 mil 50mil and 20 mil rows to move
The parent table has 10 mil rows to move
if I choose to move this data through an SSIS package what is the best way? Or is there a better way to move this data faster?
I will be doing this move only once. After that I have maintenance purge jobs that will cleanup data on a daily basis.

I need to grab data from teradata(using odbc connection).. i have no issues if its just bunch of joins and wheres conditions.. but now i have a challenge. simple scenario, i have to create volatile table, dump data into this and then grab data from this volatile table. (Don't want to modify the query in such a way i don't have to use this volatile table.. its a pretty big query and i have no choice but create bunch of volatile tables, above scenarios is just mentioned on simple 1 volatile table ).
So i created a proc and trying to pass this string into teradata, not sure if it works.. what options i have.. (I dont have a leisure to create proc in terdata and get it executed when ever i want and then grab data from the table. )

I am transferring data from Oracle tables into text files, and facing these errors.
1. I have a varaible working as an expression and my query goes into that variable and onwards that variable is passed to dataflow task, which parse the query. my query is simple saying "Select * from PLS.ABC" where PLS is my schema, but the task generates error "Opening a rowset for "Select * from PLS.ABC" failed. check that the table exists in the database. and surely the table is there.
2. I have a foreach loop that iterates through all the table names and the table names are passed onwards to the varaible query, the dataflow task inside the foreach loop gets the variable query and will generate text files based on tablenames which i have supplied in another variable to the connectionstring property of the flatfile destination. Is it possible or not. all the tables have different columns and i need the output in text files.

I have a delimited text file with 650+ columns. The sum of the column lengths of a single row, if fully populated, exceeds 30K bytes. The "killer" fields lengthwise are the "Description" fields. If they were removed from the input file, the remainig columns would occupy about 5000 bytes, which is within SQL max row length.
Can SSIS be used to created these two tables? (one without description fields, the other with those field but arranged vertically in the table rows).
The fundamental issue is I can not import a single file row into a sql table because that row length could exceed the max byte count for a row.

We are using SQL Server 2014 and SSDT-BI 2013. We have a reporting environment where business users create objects which need to be persisted for fiscal year reporting. Let's say for instance SQLSERVER1SRVR1 they create table objects like below in the reporting environment.
Accounting2014, Accounting2015 in AccountingDB;
Sales2014, Sales2015 in SalesDB;
Products2014, Products2015 in ProductsDB;
Inventory2014, Inventory2015 in InventoryDB etc....
These tables are persisted for auditing in a different environment SQLSERVER2SRVR2 for finance & audit folks.We would want to automate this process using SSIS to create tables in corresponding database and load data. I tried using For Each Loop container but the catch is I could loop the source or destination but how do we loop on Source & Destination at the same time (i.e when source is in AccountingDB destination to be AccountingDB, source SalesDB then destination SalesDB so on etc....

I have a scenario, need to create SQL server Tables dynamically.
I Have multiple xml data file on a particular location, and want to load those XML data into sql server tables, but he metadata of each xml data files are not same.
Hence the approach is that,
1. Pick first file from that location
2. Create a table according to that xml data file metada
3. load data on newly created table.
4. Pickup the next xml data files.
5. loop through, till the XML data files are exists on that location.

I have dimension data like this
persn_key persn_id address is_active updated_date
1 10 NYC 0 2015-11-04 14:19:54.817
2 10 Chicago 1 null
and Fact table like
fact_key persn_key units_purchased
1 1 10
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.

I have an SSIS package, that move file from one folder (Download) to another folder (Working), where it will be processed and passed to (Processed) folder. The folder (Working) is created at run time and deleted after finishing process. I ran this package using SQL Server Agent (I created a sql job). My problem is that the package fails to move the file from Download to Working, Although it can move it to other folders (say I skipped Working and move it directly to the already-created folder "Processed").
I traced the problem and found the error "Access is denied", when run the package without Agent (double click). I provided the necessary permissions to all levels of folders to the user XX, which I made it the (SQL Server Agent Service Account) as well as the Job Owner. By this, the package executes successfully (again by double clicking it), but with Agent it FAILS.
Why Agent cannot move the file to the run-time-created folder (Working) ?

I'm still fairly new to cubes, so bear with me. I'm trying to figure out if I should include aggregate data (e.g. total employees per facility) in a dimension table or if I should use the finished cube to get the counts (MDX?). Thanks for any help that you can provide.

Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

I have user that we just migrated his Access database to SQLServer. All went well with the migration, but then he came up withanother requirement to be able to replicate the database to a localSQL server living on the hard drive of a laptop. Before the migrationhe just copied the entire Access databse to the lap top.I tried using the Copy SQL Server Objects Task to move thenecessary tables from the production server to the laptop, but noticedit doesn't copy over the table Indexes/keys identiy fields etc. Iended up backing up the production database and restoring it to thelaptop database, but wondered if there is any way to move the tables,with their properties from one server to another? I know I can setup the backup process to run as scheduled, but the problem is the dataneeds to be moved on an irregular time table. I thought about justwriting code on the remaining Access front end to empty the localtables and then query the data from the production side to reloadthem, but I'm sure there's an easier way.Any suggestions would be appreciated.Thanks,Tom

I need to report on data from several databases on several servers. They are all SQL Server 2005 databases. I am trying to created an Integration Services task to consolidate and transform this data for easy reporting. The problem I am having is one database in particular. It has tables like this:
tblLookupData_Customer1
tblLookupParseData_Customer1
tblLookupData_Customer2
tblLookupParseData_Customer2
tblLookupData_Customer3
tblLookupParseData_Customer3
I want to use only the tables of the form "tblLookupParseData*" for this list. I can do this in Stored Procedures by dynmacally building up the sql query. I cannot find out how to do this in Integration Services. When I make Datasource Views, they seem to expect me to pick from a list of known tables. This list of tables grows as Customers are added to the system.
NOTE: The way the tables are structured was NOT my idea. I hate storing "data" in the structure of the database. Many people also do this when they create "period" tables such as "CustomerData_05_2005". It speeds up writing the data, and querying a specific table, but it is a nightmare for reporting. I cannot change this as it is not in my responsibility.

I was wondering if there's a way to compare 1 table with other (in other DB), I mean:
Table1 DB1
ID
NAME
DESCRIPTION
Table1 DB2
ID
NAME
DESCRIPTION
ADDRESS.
And when the query(or other case) gets that the table 1 doesn't contain ADDRESS, alter the table and add this field that is missing.

The following question might sound a bit stupid but I'm not a database expert so hopefully nobody minds me asking it.
Here's what I did:
1. I created an SSIS package that is supposed to import new data into my data warehouse as it becomes available.
2. Since I need to maintain some of the history I use the Slow Moving Dimensions part (set the history flag on input fields) but run into an error condition while running the package. The message basically says that I'm about to create a duplicate record which is not allowed.
Original Table1:
PK1 field1
PK2 field2
PK3 field3
field4
field5
-----------
Now I enhanced it like this:
Extended Table1:
PK1 field1
PK2 field2
PK3 field3
field4
field5
CreateDate (new)
NewDate (new)
ActiveFlag (new)
_____________________
Now on some records the package is supposed to archive history by populating the (new) fields. In order to keep the record unique (primary key constraint) thought, do I need to make the (new) fields primary keys as well?
So I guess I'm struggling with a more basic concept;)
I would appreciate if somebody could shed some light on this.
Thanks in advance.
Dirk

Every day an application creates new tables and dumps static info into them.
I would like to create a package to dynamically export those database tables to raw files for long term archive, one file per table. Here is what I have so far and the issue I am having.
1) Get a list of un-archived tables.
2) Foreach table do the following.
a. Export the table into raw file.
b. Zip the raw file.
c. Update archive tracking table.
As long as the metadata for each table is the same this package seems to work fine. However, I have many tables with different metadata. How can I dynamically get the package update the metadata column collection when it hits a new table? When it hits a table with different metadata I am getting warnings like this:
The column "some_column" needs to be added to the external metadata column collection.
The "external metadata column "someother_column" (103)" needs to be removed from the external metadata column collection.
Then I get this error:
Error: 0xC004706B at dump the table into a raw file, DTS.Pipeline: "component "OLE DB Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA"
