Oracle Error Message
PLS-00499: coercion into collection of records not supported
Reason for the Error
A SELECT or FETCH may specify a column list to be coerced into a variable which is a collection of records. This is type checked as correct, but not yet supported because of the implicit layout change required.
Solution
Express the SELECT with an object constructor around the columns and use a collection of objects as an INTO variable. Or, build the collection one row at a time coercing each row into a record which happens to be an element. Or, use a record of collections.
