Hi,
I have a table with several columns which include a NUMBER(year) and a
VARCHAR(some code) columns. The VARCHAR column has values that start with
either 1 or 2 or 3 or 4. I would like to have composite range partition key
based on YEAR and the first digit of the VARCHAR column. Is there any way I
can accomplish this? Can I use some function like SUBSTR to partition the
table based on first digit of VARCHAR column data?
Thanks for your help.
