Re: HELP!accept user input and check input value (PL/SQL)

Some thoughts...

This is something that is NOT something that can be done inside of PL/SQL. If you are going to have more "complex processing" (conditional logic based on user input), you should write a program (a form) or a 3gl around your pl/sql block.

Otherwise, in a SQL*Plus script, you could use the ACCEPT statement, and get the users response.
Include a statement: Whenever sqlerror exit failure After the accept statement, you could check for the "Y" response:

dummy varchar2(1)
Begin

   select 'x' into :dummy from dual where user_response = 'Y'; End;
/

If the user entered something other than a Y, then your script would immediately exit due to a SQLNotfound. (ora-1403) Good luck.
