I found a This book starts with some of the most basic knowledge and works with easy-to-understand examples to help you get started with simple knowledge points at and then go deeper step by step, each step will be used in concert with the example to explain to you. One small step at a time is the foundation of the next step, until the usage is relatively advanced. Oracle10g PL/SQL

Description: In PL/SQL programming, it is sometimes necessary to do a row-by-line processing of the query return result set, which requires that the query return the result set to a memory area, in order to be able to pe
