// We know week number and year.
int week = 42;
int year = 2014;

// Get calendar, clear it and set week number and year.
Calendar calendar = Calendar.getInstance();
calendar.clear();
calendar.set(Calendar.WEEK_OF_YEAR, week);
calendar.set(Calendar.YEAR, year);

// Now get the first day of week.
Date date = calendar.getTime();

I have the following table with the shown data in it:

send_date | household_ID

11-20-2014 | 123
11-20-2014 | 456
11-15-2014 | 789

I need to do 2 things:

1) Calculate the max value for send_date

2) Filter out any rows whose send_date does not match that value

In other words, I want the output to be:

send_date | household_ID

11-20-2014 | 123
11-20-2014 | 456

Row number 3 should be filtered out as its send_date is not the max.

I tried creating an aggregate, grouping by all columns, and creating a new output port called MAX_DATE with an expression of MAX(SEND_DATE), then have a filter transformation with the condition MAX_DATE = SEND_DATE

This lets all rows through, though. What can I do to make this work....

My question is very similar to the one below, but on a informatica environment:

Retrieving the index of an inserted row

Here is a brief summary of the issue: I'm trying to figure out how I can insert a row into a table and then find out what the value of the auto_incremented id column was set to so that I can insert additional data into another table. Our target is SQL server 2008. We have a table which has to be populated by informatica ETLs and the application is also using the same table - so, we can't use informatica sequence generator.

In the past when I have used Oracle database, there was a Oracle sequence generator transformation available in Informatica - but for SQL server, I am not sure.

Any solutions please?
