You should probably consider a lookup table, i.e. whatever you would
like to put in an array, put it in a separate table instead, one record
for each array entry.

If the "array" is different for each execution of the procedure,
consider using a global temporary table, GTT. You can find more on this
page (about 1/4 down):
