I am trying to delete a set of data in the target table based on a column (year) from the lookup in IICS (Informatica Cloud).
I want to solve this problem using pre/post sql commands but the constraint is I can't pass year column to my query.
I tried this:
delete from sample_db.tbl_emp where emp_year = {year}
I want to delete all the employees in a specific year i get from lookup return
For Ex:
I got year as '2019', all the records in table sample_db.tbl_emp containing emp_year=2019 must be deleted.
I am not sure how this works in informatica cloud.
Any leads would be helpful.
How are you getting the year value? A pre/post SQL may not be the way to go unless you need to do this as part of another transformation, i.e., before or after the transformation runs. Also, does your org only have ICDI, or also ICAI? ICAI may be a better solution depending on the value is being provided.
The following steps would help you achieve this.
Create an input-output parameter in your mapping.
Assign the result of your lookup in an expression transformation to the parameter using SetMaxVariable
Use the parameter in your target pre SQL as
delete from sample_db.tbl_emp where emp_year = $$parameter
Let me know if you have any further questions

I need to search an oracle table column for multiple word strings in cognos oracle query.
For example:
If Focus parameter returns multiple values as below
TRAINING
OMNIA
COUNTER
PROGRAM
And I need to search project.proj_name column like '%TRAINING%' or '%OMNIA%' or '%COUNTER%' or '%PROGRAM%'
I am trying below but I know it does only single value match not multiple. I want to know how to achieve multiple value match here.
'-99' in (#promptmany('Focus', 'string','-99')#) OR REGEXP_LIKE(proj_name, #promptmany('Focus', 'string','-99')#))
Working from Cognos Paul's solution to use output from promptmany as a table:
Assuming your query is named Q1...
Add a query. (Q2)
Add a SQL object to that query.
Set the Data source property for the SQL object.
Change the SQL Syntax property to IBM Cognos.
Define the query as
SELECT
parameterValue
FROM (VALUES
(#join('),(',split(',',promptmany('Scenarios','string',sq('N/A'))))#)
) query(parameterValue)
(change the names for your own use case)
Add a query. (Q3)
Add a join to the new query.
Add Q1 and Q2 to the empty boxes for the join leading to Q3.
Set the join as
[Q1].[proj_name] like '%' || [Q2].[parameterValue] || '%'
Add the required data items to Q3.
Since two keywords (from your parameter -> Q2) could be found in a single value (in Q1), you'll likely end up with duplicate rows. Cognos will probably handle this with its default aggregations, but keep a lookout.
Be careful with this. The new query (Q2) will probably be joined on the Cognos server, not on the database server. Be sure you have sufficient filters leading into this structure so Cognos is not trying to process your entire database.
This worked for me with SQL Server. I don't have an Oracle database to test against, but using IBM Cognos as the SQL Syntax should handle that.
To use REGEXP_LIKE to solve this problem, you'll need to get the second argument correct. I can't see any reason to see the error message ORA-00996: the concatenate operator is ||, not |, but I'm not working with your code in your system.
You don't specify which version of Cognos, or even which Cognos product, you are using. I'll assume Cognos Analytics 11.1.7.
To determine what Cognos Analytics is doing with your macro, create a very simple query with one item from the database (preferably from a very small table) and another data item that contains the macro. So the data item expression is:
#sq(join('|',split(',',promptmany('Focus','string','-99'))))#
When you run this, you may not be prompted. You'll see the value is -99. So to test this we'll need to remove the default so that the prompt becomes required.
#sq(join('|',split(',',promptmany('Focus','string'))))#
Be sure to enter more than one value when you test.
In my environment, the parameter returns a value that is my values surrounded by quotes (') and delimited by semicolons (;). So my tests produced the following:
expression
value
#sq(promptmany('Focus','string'))#
'PROGRAM';'COUNTER';'TRAINING'
#sq(join('|',split(',',promptmany('Focus','string'))))#
'PROGRAM';'COUNTER';'TRAINING'
#sq(join('|',split(';',promptmany('Focus','string'))))#
'PROGRAM'|'COUNTER'|'TRAINING'
replace(#sq(join('|',split(';',promptmany('Focus','string'))))#, '''', '')
PROGRAM|COUNTER|TRAINING
Your mileage may vary.
At this point, you know which macro to use in the REGEXP_LIKE function.
I have a use case where i am mapping two tables to the same object.
In this object i have a string called source and I want to be able to set the table name or the database name to this variable.
Any ideas on how to achieve this?
I have thought about iterating over my list and manually setting it but this has the potential to waste a fair chunk of time.
I appreciate this is somewhat of an odd request so this may be the only way but am hoping for a solution that maps the source variable when hibernate is mapping everything else.
if i had understood correctly your issue , then your solution might be the MappedSuperClass , in which you must have an abstract class , which will have the common fields of the two tables and then you will extend that to the two entities you want , which will point to two different tables.

You could try to achieve this with Load listener or Interceptors. In the listener/interceptor you can check what the data source is and populate the source field accordingly.
In the end i ended up using a formula to map my variable to a select statement which was sufficient for what i needed.
I have a Pesky SSRS report Problem where in the main query of my report has a condition that can have more than 1000 choices and when user selects all it will fail as my backend database is Oracle. I have done some research and found a solution that would work.
Solution is
re-writing the in clause something like this
(1,ColumnName) in ((1,Searchitem1),(1,SearchItem2))
this will work however when I do this
(1,ColumnName) in ((1,:assignedValue))
and pass just one value it works. But when I pass more than one value it fails and gives me ORA-01722: Invalid number error
I have tried multiple combination of the same in clause but nothing is working
any help is appreciated...
Wild guess: your :assignedValue is a comma-separated list of numbers, and Oracle tries to parse it as a single number.
Passing multiple values as a single value for an IN query is (almost) never a good idea - either you have to use string concatenation (prone to SQL injection and terrible performance), or you have to have a fixed number of arguments to IN (which generally is not what you want).
I'd suggest you
INSERT your search items into a temporary table
use a JOIN with this search table in your SELECT
Is there any way to use a variable in the from part (for example SELECT myColumn1 FROM ?) in a task flow - source without having to give the variable a valid default value first?
To be more exact in my situation it is so that I'm getting the tablenames out of a table and then use a control workflow to foreach over the list of tablenames and then call a workflow from within that then gets data from these tables each. In this workflow I have the before mentioned SELECT statement.
To get it to work properly I had to set the variable to a valid default value (on package level) as else I could not create the workflow itself (as the datasource couldn't be created as the select was invalid without the default value).
So my question here is: Is there any workaround possible in this case where I don't need a valid default value for the variable?
The datatables:
The different tables which are selected in the dataflow have the exact same tables in terms of columns (thus which columns, naming of columns and datatypes of columns). Only the data inside of them is different (thus its data for customer A, customer B,....).
You're in luck as this is a trivial thing to implement with SSIS.
The base problem for most people is that they come at SSIS like it's still DTS where you could do whatever you want inside a data flow. They threw out the extreme flexibility with DTS in favor of raw processing performance.
You cannot parameterize the table in a SQL statement. It's simply not allowed.
Instead, the approach that people take is to use Expressions. In your case, assuming you had two Variables of type String created, #[User::QualifiedTableName] and #[User::QuerySource]
Assume that [dbo].[spt_values] is assigned to QualifiedTableName. As you loop through the table names, you will assign the value into this variable.
The "trick" is to apply an expression to the #[User::QuerySource]. Make the expression
"SELECT T.* FROM " + #[User::QualifiedTableName] + " AS T;"
This allows you to change out your table name whenever the value of the other variable changes.
In your data flow, you will change your OLE DB Source to be driven by a query contained in a variable instead of the traditional table selection.
If you want an example of where I use QuerySource to drive a data flow, there's an example on mixing an integer and string in an ssis derived column
Create a second variable. Set its Expression to create the full
Select statement, using the value of the first variable.
In the Data Source, use "SQL command from variable" option for the
Data Access Mode property.
If you can, set a default value for the variable you created in step
That will make filling out the columns from your data source much easier.
If you can't use a default value for the variable, set the Data
Source's ValidateExternalMetadata property to False.
You may have to open the data source with the Advanced Editor and
create Output columns manually.
Following is the data model of the dashboard I am facing problem in:
http://blob:http://stackoverflow.com/f3e40cfe-e009-4d03-bcf5-b7b4305c18c4
Now, what i want to achieve is that in Case there is a filed named Manufacturing_Date. And in MWODefetcs there is a field named Defect_Date. What i want is that when ever a record is selected from a table containing cases from Case corresponding records are shown in another table based on the exact match of Manufacturing_Date=Defect_Date.
As simple as it sounds, i can not seem to accomplish it. I have tried the following expressions to no avail:
Count({<[Defect_Date_text]=p([Manu_text]),FaultID=,DEFECT_CODE=>}MFG_BARCODE_NUM)
sum({$<Defect_Date ={"=$(Manufacturing_Date__c)"}>}Defect_Date)
Do the 2 tables need to be directly linked. Is it the intermediary iFaults table that is preventing me to accomplish it?
Please help.
you should use the P() set expression like this:
sum({$<Defect_Date =P(Manufacturing_Date__c) >}Defect_Date)
