Using the database language to describe a cursor is a position entity that maps on a row of data in the context area result set. A user can use a cursor to access any row of data in the result set, and the row data is manipulat

, it is inevitable to use the set type in anonymous subprograms. In addition, if a function written in a programming language involves set operations and wants to rewrite it to an Oracle function for some reason, it is necessary to understand Oracle set operations.Define Collection type Define the collection type before declaring the variables of this type. You can define a collection type in the Mode Level, package, or
