问题
I want the output of dates from particular range in a specific format
date1: 2019-06-18
date2: 2019-06-22
Output will be:
2019-06-19|2019-06-19,2019-06-20|2019-06-20,2019-06-21|2019-06-21
I want to do this via Datastage Component only, no unix, no perl script.

From one input record you can generate multiple rows witha transformer loop. Date1 is frim the inout and date2 could be built with currentdate() in the transformer. In the loop @IERATION is the the loop counter so you could use DateOffsetByDays with your input date and @ITERATION as second parameter. Run the loop while it is <= currentDate()
In a second transformer you could then concat whatever date format you need - ot could be helpful to add a artificial numer to all rows produced from one input row.
