I am trying to merge two tables after an aggregation transformation. Since I want few columns to pass through. Could someone suggest the transformation I need to use. Merge and Merge Join I am not able to use since I have 12489 rows from one output and 241 rows from another output. I want to add these aggregated values as just separate columns not related to previous columns.

I need to apply fuzzy lookup on multiple table columns. for example - I have table A which contains 4 columns(50% matched data ) which look 4 different tables which contain 100% matched data. I want to apply fuzzy lookup on 4 different data sets which match data from different 4 tables and give me correct data for table A. How can I do this.
In the edit querys go to Merge Querys > Merge As New and check the Use fuzzy matching to compare the merge in the pane (You also have some fuzzy merge options here for example the match percentage) and hit OK.
If you have more tables to match with, just repeat the first step again on the newly created table.
You can also pass a transformation table where you cen specify some matching criterias.
I have four datasets that get information for four different things (a unique set of fields for each one), but that can be joined using a field they share. I need to get them all into a tablix that will have four rows, one for each dataset per the linking field. How do I do that?
Currently I can only put in values from one dataset.
Often the best idea would be to create a query that joins the datasets in the sql. If that is not possible, you can look into using the Lookup function to find info from other datasets in your report. The related Lookupset function is able to retrieve sets of information and may be useful as well.
I am trying to use the merge join in ssis; however, when i am putting in two columns on basis of which i am joining it is giving me correct results. But as soon as I add more columns in one of the sources, it gives me matches with nulls only.
In the below SSIS data flow task I have two Salesforce.com sources
The top one returns one row, one column named is_current
The top bottom returns one row, one column named is_deleted
Where the question mark is, what SSIS component do I use to transform the above into one row with columns is_current and is_deleted?
The Salesforce Object Query Language (SOQL) doesn't support UNION ALL or independent subqueries, otherwise I'd just handle both in SQL in the source task.
Merge Join Transformation should be used here. However you need join keys to perform join. In this case you can add artificial columns in each flow with same values (1 for example) by using Derived Column Transformation and use them as join keys.

I have data from two different source locations that need to be combined into one. I am assuming I would want to do this with a merge or a merge join, but I am unsure of what exactly I need to do.
Table 1 has the same fields as Table 2 but the data is different which is why I would like to combine them into one destination table. I am trying to do this with SSIS, but I have never had to merge data before.
The other issue that i have is that some of the data is duplicated between the two. How would I only keep 1 of the duplicated records?
Instead of making an entirely new table which will need to be updated again every time Table 1 or 2 changes, you could use a combination of views and UNIONs. In other words create a view that is the result of a UNION query between your two tables. To get rid of duplicates you could group by whatever column uniquely identifies each record.
Here is a UNION query using Group By to remove duplicates:
SELECT
MAX (ID) AS ID,
NAME,
MAX (going)
FROM
(
SELECT
ID :: VARCHAR,
NAME,
going
FROM
facebook_events
UNION
SELECT
ID :: VARCHAR,
NAME,
going
FROM
events
) AS merged_events
GROUP BY
NAME
(Postgres not SSIS, but same concept)
Instead of Merge and Sort , Use union all Sort. because Merge transform need two sorted input and performance will be decreased
1)Give Source1 & Source2 as input to UnionALL Transformation
2) Give Output of UnionALL transfromation to Sort transformation and check remove duplicate keys.
This sounds like a pretty classic merge. Create your source and destination connections. Put in a Data Flow task. Put both sources into the Data Flow. Make sure the sources are both sorted and connect them to a Merge. You can either add in a Sort transformation between the connection and the Merge or sort them using a query when you pull them in. It's easier to do it with a query if that's possible in your situation. Put a Sort transformation after the Merge and check the "Remove rows with duplicate sort values" box. That will take care of any duplicates you have. Connect the Sort transformation to the data destination.
You can do this without SSIS, too.
