How to delete from VARRAY tips

Oracle Database Tips by Donald BurlesonFebruary 21, 2015

Question: How do I delete an entry within a VARRAY?

Answer: In addition to the constructor type Oracle also provides collection methods for use with VARRAYS and nested tables. These methods cannot be used outside of PL/SQL. Collection methods cannot be used in DML but only in procedural statements.

DELETE removes specified items from a nested table or all of a
VARRAY. DELETE specified with no arguments removes all instances of a collection. For nested tables only DELETE(n) removes the nth instance and DELETE(n,m) deletes the nth through the mth instances of the nested table that relate to the specified master record.
