SQL script with a prompt functionality.

Question

Hello experts,
I tried searching this on the net but was unsucessful...
Bascially I need to update an sql script with a prompt functionality..Basically I would like a user prompt that would enter 'Yes or No' to compile invalid objects using utlrp.
If Yes, it should compile it
If No it should exit out...
Can anyone please help.. Need to do this today.

Hi,
As someone suggested, you're probably better off doing this at the OS level.
SQL*Plus does not have any good mechanism for conditional branching. One trick you can do in SQL*Plus is to run one script from another by saying <tt>@@filename</tt>. By using a substitution variable (which can be defined based on the results of a query) in place of a literal filename, you can make this dynamic.
For example, the following script runs either
recompile.sql or
goodbye.sql
based on the answer to a prompt:
ACCEPT     recompile_now      PROMPT        'Do you want to recompile objects now?  '
COLUMN     next_script_col        NEW_VAL next_script
SELECT     CASE     
          WHEN  UPPER ('&recompile_now') LIKE 'Y%'
          THEN  'recompile'
          ELSE  'goodbye'
     END     AS next_script_col
FROM     dual;
@@&next_script<tt>@@filename</tt> assumes filename.sql is on the same directory as the calling script. You could also give a full path name using only one @-sign:
<tt>@pathname</tt>
