Idea Summary
There is are TO_CHAR, TO_DATE, TO_TIMESTAMP functions in the IR Actions → Format → Compute dialog, but no TO_NUMBER.
Use Case
I have an interactive report column that can contain data that may contain all digits, or alphanumeric data. I want to create a column that will sort properly by left-padding numbers with zeros, by doing a case statement that would do a
TO_NUMBER(Student_ID default null on conversion error …)
to do that.
