在Oracle的同一后台处理中生成输出

Question

SPOOL c:\out.SPL

    SELECT * FROM a WHERE ACCOUNT_NUMBER='&CRN' ;
    SELECT * FROM b WHERE ACCOUNT_NUMBER='&CRN' ;

    Spool off
    accept op prompt 'Do u want to generate el spool,type y ' default 'n'
    SAVE c:\query2.SQL 
       select * from getm_liab   where liab_no='a' ;

    column c me new_value x
    set termout off
    select decode(lower('&op'),'y','C:\query2.SQL','n', 'null') c from dual;

    spool c:\out.SPL APPEND
    @&x

The above script is I run set of queries first and I will run remaining set of queries only when user types y. But it is not working please suggest

Answer 1

content of q1.sql:

accept op prompt 'Do u want to generate el spool,type y ' default 'n'

column c new_value x
set veri off
set echo off
set head off
spool qyn.sql
select decode(lower('&op'),'y','@','n', '--')||'q2'  from dual;
spool off

@qyn '&1'

content of q2.sql:

select 'boe' from dual where dummy = '&1';
select 'oops' from dual where dummy = '&1';

sqlplus foo/far@orcl @q1 X output with Y:

This is one of the ways to handle this. Easiest is to use the positional variables but you can also define them as named variables.
