Question

goto1:

           --- update tabellen
    update dgdtw_lockedinfo set ciuserid = couserid where locknr = &lock;
    update dgdtw_topografie set locknr = '' where locknr = &lock;
    update dgdtw_topografie set verval=sysdate where id= &lock;
    commit;

    accept var prompt ' yes or no '

    if (var = yes) then 
    goto1

    and if (var = no)
       exit
    end if

如果用户输入是

，则需要重复一个功能

有没有办法按输入重复命令？

Answer 1

如果你真的必须这样做，可以通过start命令使用递归来循环。

使用内容

创建'递归结束'文件stop.sql

prompt OK, end of repeat
exit

使用以下内容创建文件repeat.sql：

set echo off verify off

select 'Your SQL statements go here' from dual;

accept var prompt 'Repeat the SQL statement [yes or no] ? '

define doit = 'stop.sql'
column doit new_value doit noprint
set termout off
select 'repeat.sql' doit from dual where upper('&var') like 'Y%';
set termout on
start &doit.

这是一个示例运行：
