我有以下代码:
set output spoole
select * from displays where displayname='dsp020a'
select * from forms where formname in (select formname from displayforms where displayname='dsp020a')
select * from formfields where formname in (select formname from displayforms where displayname='dsp020a')
第三个选择使 ZIM 崩溃,并出现以下错误:
*** ZIM System Error *** The Zim tree pool has overflowed. Type BYE to exit from Zim.
我做错了什么,我该如何解决?
