Answer / cherie
In Oracle/PLSQL, the cardinality function returns the
number of elements in a nested table.
The syntax for the cardinality function is:
cardinality( nested table column )
nested table column is the column in the nested table that
you wish to return the cardinality for.
Note:
If the nested table is empty, the cardinality function will
return NULL.
If the nested table is a null collection, the cardinality
function will return NULL.
