Pl/sql creates and executes ORALCE stored procedures and returns the result set

Because I used to use sql server many , Now use it all at once oracle , I'm not familiar with tools , Limited to sql server Thought  

Online search , And ask friends , Told me a lot , what loop ah ,decalre ah ,package ah , What command window , what sql plus ah , What doesn't support pl/sql ah . It took hours .. It's all misleading , In fact, nothing is needed .

Just define a result set , Save things in the result set and it's over （ This result set is called a cursor ）, Create the stored procedure first ：

create or replace procedure Demo(data out sys_refcursor) is
begin
  open data for select * from gsminfo;
end Demo;

Then directly execute OK , The method of execution is as follows ：

Stored procedure found , Right click , Choose a test :

Then the page that appears , Then select run ：

Then just look at the result set directly , Pay attention ,oracle pl/sql This tool , The result set of stored procedure is not humanized , Compared with sql server It's a lot worse , The result set is in a very hidden place , As shown in the figure , Just click on it
