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

上面的脚本是我首先运行一组查询，只有当用户输入y时我才会运行剩余的查询集。但它没有用，请建议

Answer 1

q1.sql的内容：

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'

q2.sql的内容：

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

这是处理此问题的方法之一。最简单的方法是使用位置变量，但也可以将它们定义为命名变量。
