Adding Rank for a Column in SSIS Derived Column

H
I want to add rank to a column in ssis in a derived column actually.
Can u please tell how to add it and the syntax for adding it in a derived column.

Thanks,
Can you please give the script for the same.
I am unable to write the script for my logic to implement in SSIS.
I will be very thankful if some one could help me with it.
Thanks in Advance.
Sam thats too generic there would be several ways to solve one problem ...
can u tell us what is ur source [i mean table view THE DATA which records tuples you suspect is having duplicates ]
on what basis u decide duplicate ? and what row qualifies to go into destination ... for eg say ur source is
select id,name, date from source_table
duplicacy could mean id and name being repeated multiple times and may be business rule is like pick up rec with latest date vale if thats the case go for source as :
select id, name,max(date) from sourcetable
group by id,name
if all the columns are repeating in your source table may be use DISTINCT ...
would be great if u give ur destination, source and business requirement ..
if you have got primary key violations and any record qualifies then may be simply at destination component set Ignore failure property and ur job is done ...
may be removing duplicate at source itself ... might solve ur problem
check out more on duplicates : http://blog.sqlauthority.com/2009/06/23/sql-server-2005-2008-delete-duplicate-rows/
i hope u got the idea ...
Hope that helps ... Kunal

Report Attributes: Add column link and derived column

On the Report Attributes page (4000:420), under the Tasks list on the right side of the page, there are 2 links, "Add column link" and "Add derived column". This is the first time I am noticing them.
The usage is clear, they add columns to the report to function either as a drill-thru link column or just a read-only derived field.
Doing it this way does NOT modify the source query for the report region.
Is there any benefit to using this feature versus adding a "null column_link" or "null derived_col" columns to my source query then setting attributes for those columns?
Thanks

Well, one disadvantage I can see of using the 'Add Column link' is that if I have more than 1 of such columns, they all show up as '[column link]' on the Report Attributes page with no way to tell what the underlying links are. Instead, if I were to manually add these dummy columns to my query itself, I would give them meaningful column aliases that indicated where they link to.
Suggestion: Maybe a tooltip could be added to the Report Attributes page for such columns which indicate what the underlying link is without actually going to the Edit page for that column.
Thanks

How to cast a column of a derived column in a view to NULL

I have a derived column in my view and this column by default is picked up as not null.
I want to cast it to null how can i do it ?
Actual column
column1 varchar(3) not null
Expected column
column1 varchar(3) null

Shridar I havent defined it but the derived column has been picked up as not null which is strange
CREATE VIEW test
AS
SELECT
CASE
WHEN COMPANY_SIZE IS NULL then 'a'
ELSE 'b'
END AS
column1 ----- added derived column identifier
,[Company_Size] AS [CompanySize]
FROM xyz

Avoiding derived columns for mapping purposes only

Hi. In 2012 has there been any advancement that would alleviate us from adding a derived column simply for the purpose of mapping an existing var or param to an oledb output column?

Hi DB042189,
According to your description, what you would like to do is directly mapping a variable or parameter to an Output column of a Data Flow Task control without adding a new column through the Derived Column transform. If so, this is not supported in SSIS 2012
currently. I would suggest you submitting a wish at

EXPRESSION SYNTAX REQUIRED FOR DERIVED COLUMN

Hi
I've had a look around and can't find the correct syntax for an Expression in a Derived Column task.
Below is the logic in TSQL. Please could someone help me convert it?
CASE
WHEN FIELD1
=
'A'
AND FIELD2
IS
NULL
THEN
'A'
WHEN FIELD1
=
'B'
AND FIELD2
IS
NULL
THEN
'B'
WHEN FIELD1
=
'A'
AND FIELD2
=
'C'
THEN
'C_A'
WHEN FIELD1
=
'B'
AND FIELD2
=
'C'
THEN
'C_B'
WHEN FIELD1
=
'A'
AND FIELD2
=
'D'
THEN
'D_A'
WHEN FIELD1
=
'B'
AND FIELD2
=
'D'
THEN
'D_B'
ELSE
'0'
END
Thanks in advance
Lucy

Hi Lucy,
Try like below expression in derived columns..
((FIELD1 = 'A'
&& FIELD2 IS NULL)
? "A" :
(FIELD1 = 'B'
&& FIELD2 IS NULL)
? "Y" :
(FIELD1 = 'A' && FIELD2 = 'C' )?
”C_A” :
(FIELD1 = 'B' && FIELD2 = 'C' )
? “'C_B” :
(FIELD1 = 'A' && FIELD2 = 'D' )
? “'D_A'” :
(FIELD1 = 'B' AND FIELD2 = 'D' )
? “'D_B”
: "0"))

Drill down in Table or Pivot for derived column

Hi All,
I have a requirement like Top 5 products should show the product names and remaining should go to *'Others'*. I achieved it by using Rank function and case when.
ex: case when rank(product) <=5 then product else 'Others' end
Now the problem is, I am not getting the Drill option for this column. When I use product column without case when or case when on same column like
case when product = 'xyz' then 'abc' else product end. In this case drill is working.
Can anybody suggest me to get the drill on the derived columns.
Thanks in advance

A similar thread was recently talked about here:
In OBIEE charts, how do you make drill downs work on custom formulas?
With a calculated column, you need to make sure the source query and destination query have the EXACT same formula and the same name for the field. If it is not 100% identical, it may not work correctly. (I typically use the NAVIGATE function to get to the second query rather than the Drill function.)
Now in some cases, if you try to create a second drill down query with more details in it, the original formula doesn't work the way you want it to. The calculated formulas have to make sense in both source query and destination query in order to work properly. If you have a ranking of the Top 5 Products in the source query, the destination query also has to have the same ranking of Top 5 products in order to work. If you add more fields into the destination query (e.g., adding on product attributes, or # of records associated with that product name etc.), then sometimes the ranking / aggregation in the destination doesn't add up the same way. This causes the system to think that the formulas are different and prevents the drill down.
I managed to get around this by having a 3rd query in between the original summary view and the detailed data view. So the sequence would be (for example):
- Dashboard based summary query (including the calculated ranked product names formula)
- drill down into virtually identical query (add on one slight bit of difference here, for example adding on a second Product Name field ... not a calculated version, but the actual name). Create a drill down this time by clicking on the regular Product Name field (don't drill down on the custom formula)
- final detailed drill-down query
You can format this intermediary drill down query to explain to users that they need to click a second time.
It's not ideal, but it should work. Hope this helps.

Can't change the connection string of SSIS package with derived columns?

We upgraded SQL server 2008 to 2012, copied and converted all SSIS packages from Visual Studio 2008 to 2010. When I opened a package in VS 2010 and tried to change the connection string, in the local connection managers, if the data source is another
SSIS package B(.dtsx file) with derived columns, I can't change the connection string of package B. When I opened the file connection manager editor for package B and tried to locate a dtsx file in another location, saved the change, reopened the project.
Package B still pointed to previous file. Other packages without derived columns work fine. Any thoughts?

We are using the package deployment model and refer to other packages in the same project. If
we changed the path of package B (with derived columns) to "D:\Visual Studio 2010\xxxx", and refer it in package A, in the A's connection manager, the connection string of package B is still its previous location "D:\Visual
Studio 2008\xxxx". When we ran the package A in the SQL server agent, the data source is still
"D:\Visual
Studio 2008\xxxx", so how can I change it to "D:\Visual
Studio 2010\xxxx"? Why has the package C (without derived columns) no such problem? thanks.

SSIS: Using CASE Statement Within A Derived Column Transformation Expression

The following is my Data Flow:
Ole DB Source > Copy Column > Derived Column >Ole DB Command
My OLE DB Source has the following SQL command task:
SELECT *
FROM Repair R
LEFT OUTER JOIN Vehicle V
ON R.SN = V.SN
AND R.Reg = V.Reg
LEFT OUTER JOIN Product P
ON R.PID = P.PID
This yields a column of concern for me named PartNumber, which are represented by the following 2 formats:
The following are my Copied Columns:
Input Column = PartNumber
Output Alias = Copy of PartNumber
The following are my Derived Column expressions:
Derived Column Name Derived Column Expression
Name Replace 'PartNumber' LEFT(PartNumber,FINDSTRING(PartNumber,"-",1) - 1)
Copy of Name Replace 'Copy of PartNumber' RIGHT([Copy of PartNumber],LEN([Copy of PartNumber]) - FINDSTRING([Copy of PartNumber],"-",1))
So My PartNumber Column is Replaced with ######### of type
string and the Copy of PartNumber column is replaced with
#### of type int
As I stated earlier PartNumber also is in the format of %-%-% which raises the following question:
How can I replace PartNumber Column with NULL if in format of
%-%-% and take the PartNumber and put it in new column named
SubPart while keeping all the logic within SSIS objects?
So in essence I want to do something like the following:
PartNumber = CASE
WHEN 'PartNumber' LIKE '%-%-%'
THEN ABC = PartNumber AND PartNumber IS NULL
END
I have tried the case statement in a Derived Column expression and is not working. Would I add the
CASE statement to the SQL command task in my OLE DB Source?
I hope this question is concise for you.

If it must be in SSIS, I would put a derived column stage earlier in the process to do my check for me. Then in the second derived column stage do the check against each output column (part, subpart, copy of part) to decide which way it goes
PS Not sure if it's a 2012 function but SSIS has a function called TOKEN that will allow you to pull your subparts for you rather than the left/right you are doing

Derived Column : for Lookup type column with 'Allow Multiple Selection' : True in sharepoint list

Hello,
I have one column where field type is Lookup but 'Allow Multiple Selection' is true in SharePoint List.
So, in this scenario data from the SharePoint list is being exported as below.
1;#Red;#3;#Blue;#4;#Black;#5;#Green
Now resultant text exported to SQL Table should be :
1,3,4,5
OR
Red,Blue,Black,Green
Either way it is fine. How can we get this using Derived Column and Data Conversion?
I am able to do this for single occurrence using below expression.
(DT_STR,100,1252)(SUBSTRING([BusinessUnit],FINDSTRING([BusinessUnit],"#",1)+1,LEN([BusinessUnit])-FINDSTRING([BusinessUnit],"#",1)))
Please suggest.
Thank you,
Mittal.

Your best bet would be to do this in sql using a string parsing udf as below
http://visakhm.blogspot.com/2010/02/parsing-delimited-string.html
You can make it into procedure and call it from oledb command task.

Expression for derived column

Hi,
In my SSRS package I have a field which may have a null value. I want to create a derived column that does the following:
If the value is null replace with 0 else return the value
How do I script this?The fiels is my [Qty Remaining] field. I thought it might have been something like this but I was obviously wrong:
ISNULL([Qty Remaining]) ? "0" : [Qty Remaining]
Cheers
Paul

Try this
ISNULL([number]) ? (DT_I4) "0" : [number]
"0" is unicode string, you have to convert it to number, in my case integer or choose yourself

How can I set a value of column in SSIS by using Replace

How can I set a value of a column in SSIS using a Replace in Derive columns. I have here NameCode and I need to Set = 1 Where NameCode like LIKE '____99____'
eg. 1006993010... if 5th and 6th characters are 99
Else 0
Hope to hear from someone soon and I appreciate great help here.

If NameCode column is integer then you have to cast it correctly to String.
I am adding that to the expression provided by Rajen.
SUBSTRING((DT_WSTR,20)ProductCode,5,2) == "99" ? 1 : 0

Checkbox derived column in report

I added an HTML checkbox that has the same name for every row and a value of the pk for that row to a report. I also added a submit button.
The submit button branches back to the same page.
If I don't check ANY checkbox buttons the submit button just takes me back to the same report. If I even click one checkbox, I get a 404 "Page cannot be found" with the url saying: pls/htmldb/wwv_flow.accept
why is this procedure doing this? How can I add a derived column containing a checkbox to a report for selection of report rows for further processing or adding of these rows to a "shopping cart/basket".

Enough with this ..... link
http://www.oracle.com/technology/products/database/htmldb/howtos/checkbox.html
How many times do we have to see it in the forum....Enough.....
Its so frustrating giving the same link time and time again...And the funny
part is that most people's questions has nothing to do with that. But
still some geniuses give the same link....I just feel so sorry for people
who are struggling to get a answer and some idiots give the same link

A task of getting an extra column using ssis

hi...
I need a help in solving this task. I did this in sql but don't know, why I am getting error in ssis.
the task is about creating a new column, in this column I should get the id in such a way that the first two letters and the last two letters before @ are displayed and other letters are replaced by *.
my source column:
MY DESTINATION COLUMN
ID NAME   EMAILID
ID    NAME         EMAILID                    NEWEMAILID
1   AKHI     AKHI1985@
1     AKHI        AKHI1985@               AK****85@
2 SRESHTA SRESH_GG@                                        2
SRESHTA SRESH_GG@              SR****GG@
3 RENU      RENU_COOL1989@                               3
RENU       RENU_COOL1989@     RE********89@
please solve this.

If your source is database table you can do this in sql itself
ie use a query like below in OLEDB source
SELECT ID,NAME,EMAILID,STUFF(EMAILID,3,CHARINDEX('@',EMAILID)-5,REPLICATE('*',CHARINDEX('@',EMAILID)-5)) AS NewEmailID
FROM SourceTable
And just map the new column to destination table NEWEMAILID column
If your source is a file or some other type then you need to do this inside a derived column in SSIS data flow task
for that use an expression like
ColumnName Expression
NEWEMAIL ID <Add As New Column> SUBSTRING([EMAILID],1,2) + REPLICATE('*',FINDSTRING([EMAILID],"@",1)-5) + SUBSTRING([EMAILID],FINDSTRING([EMAILID],"@",1) + 1,LEN([EMAILID]))

How can I implement an user function in a derived column of a report ?

Hello,
I've a report and added a derived column.
In this column should be displayed the result of a function.
GETANZGJMONATE ( to_date(#START_AFA#,'DD.MM.YYYY'), #ND#, :P302_GJ );
How can I implement this?
Thanks in advance
Regards Ulrike

Ulrike - I would do this in the SQL statement (there may be other ways).
Presumably START_AFA and ND are table columns?
Presumably you've also created the GETANZGJMONATE function?
So, something like this should work (this also assumes that START_AFA is of a DATE type - you'll need the TO_DATE call if not):
SELECT COL1
, COL2
, START_AFA
, ND
, GETANZGJMONATE (START_AFA, ND, :P302_GJ)
from TABLE
where ...
Can't remember if you have to grant any particular execute permissions on the function ('grant execute on GETANZGJMONATE to public', for example) when you call it from SQL on a page, but you could try that if the function call fails.
Depending on what's in :P302_GJ and what the function parameter data type is, you might need to use the '&P302_GJ.' syntax or TO_NUMBER etc.
Hope this helps.

John.

Hi Cherukuri19,
If I understand correctly, you checked the data type of the input column from the Advanced Editor for the Derived Column component, right? Based on the error message, it seems that the data length of the target column outputted by the component above the
Derived Column (may be the Source Component) is more than 10 characters. However, you just modify the Input Column data type and length from the Derived Column component, hence, the data truncation error occurs. In this condition, you can avoid this issue
by using the following steps:
Keep the original nature of the SDate Input Column, e.g. don’t set the data type of this column to [DT_STR] or set its length.
Use the following expression instead for the Derived Column:
(DT_STR,10,1252)((DT_DBDATE)SDate)
