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 a grid view where I need to show data of more than a table, each record in a row (Not relations).
Thus, a group of grid rows may come from table one, another group of rows from table two, ect...
For example, I need to select from tbl1 rows (suppose r1 to r10), and from table tbl2, rows (suppose r11 to r20) r1 to r10 and r11 to r20 may have a lot of common id's (because from different tables). And I want to show all these records in a single grid view, with search and actions enabled.
I have made an attempt to get data in arrayDataProvider, and it worked perfect.
The problems I am trying to fix are two:
1. Enabling the searchModel in the grid. (For that, I have also get all data in the search model in arrayDataProvider, but still need to enable search).
2. I need to know which record is selected for(view, update, or delete) and take action based on the selection, because the same id may exist in the grid multiple times, each from a table.
To Enable Search:
1. I have used all search models to return arrays based on filtering queries.
2. I have used a basic search model that includes common attributes between all tables, it calls functions from other search models to get array from them, then it concatenates all these arrays and returns them as an array data provider.
3. Needed some attention when dealing with parameters in search models, because they are using the same model as the basic, they have more fields.
When I treat id's and acyions on rows, I will post the method.
If any one having the same issue, and need help, I will be :-)
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.
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 have following Scenario
a. Oledb Source is fetching data from a remote Server.
b. Data is being passed to Lookup.
c. Here i need to Compare Two Source Columns with One Detination Column
I am not getting how i can do this? Should i use two Lookup transformations, If yes then How?
Unless I'm missing a nuance of your question, the lookup of a single value is the same as a lookup using multiple columns.
On the left (source) side, drag the column to its mate on the right (lookup) side. Repeat until you've matched all the fields that need to be matched.
Optionally, select the output columns you need.
I am trying to develop a report having two tables with one single data set.each table is filtered with the user giving a date parameter. is there any way that I can get the value present in a text of table1 into the table 2.
If you have a report with two table objects in it, both of which point at the same dataset, then all of the data in either table will be available in the other table - the only reason that one value would be available in one table but not the other is if the tables have different filter conditions. Therefore, you may need to amend the filter conditions.
