These options not showing for me

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 created an SSIS package and I used Merge Join to join a Dimension with the result of another Merge Join and I got the following error:
Both inputs of the transformation must contain at least one sorted column, and those columns must have matching metadata ssis
I have found that the issue is related to the data type of the two sorted columns, I just made a conversion to make both of them "INT" and everything is going fine.
The message is pretty clear. SSIS merge operations required that the data to be compared is sorted so comparisons are faster.
Make sure that you are retrieving ordered data from your database using the ORDER BY clause (if on SQL), and mark the columns with their corresponding order at the property IsSorted.
If you can't have the data ordered at the source, you can add a Sort operation in SSIS which will sort the merging columns (before the actual merge). You will have to do this on both flows before the merge. Please be adviced that using this componene will block the data flow until all rows are sorted.
The Merge error message will go away once you join both data flows with sorted columns.
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 :-)
In my current SSIS data flow task, I feed my data flow into a Lookup tool. Matches are inserted into one table and non-matches are inserted into another table.
I did it this way because this is what I was able to learn from the available tutorials at the time.
However, it seems wasteful because I don't really want the non-matched records at all. Is there a way to tell SSIS to discard the non-matched records entirely rather than store them in a table?
The lookup dialog doesn't appear to give me an option for "ignore non-matches."
Is there some way to achieve this desired behavior?
If lookup = match, insert matched records into table (as currently done)
If lookup not a match, ignore (or discard) non-matched records
Leave Redirect rows to no match output as you currently have specified.
Select the "non-matched" branch and delete the destination.
Done.
Really, that's it. The rows will still be in the memory buffers of your data flow but they won't carry to the Match destination as they'll be logically segmented.
Personally, I have a Row Count wired up so I can count the original Rows, the matched rows and the unmatched rows. It helps me audit how the package has performed over time but there's nothing wrong with not using an output stream from a component.
I tried to configure the lookup to only send no match output (Only want records that haven't been written to destination), but the same amount of records get written over and over. Is there something I am missing? I have the fields the lookup needs to match on, so if no match I want it to write to new location.
Specify how to handle rows with no matching entries is set to Redirect rows to no match output.
I would normally just use a query but where I am at the source and the destination are on two different servers.
With that Lookup configuration, you will have 2 green output paths available from the Lookup object. One will be the Lookup Match Output and the other will be the Lookup No Match Output.
When connecting the Lookup to your downstream transformations, you need to carefully select which output path goes where. The one you probably want is the Lookup No Match Output.
