Operand should contain 1 column(s)
select (vid_id, vid_name, vid_leadrole, vid_desc, vid_info, vinfo.cid, vid_serialstate)
from tb\_videoinfo vinfo where vinfo.cid in (select cid from tb\_category where pid=\#\{cid\})
会报 Operand should contain 1 column(s) 错误: Operand should contain 1 column(s)
搜索一下,去掉红色的括号就Ok了,
select vid_id, vid_name, vid_leadrole, vid_desc, vid_info, vinfo.cid, vid_serialstate
from tb\_videoinfo vinfo where vinfo.cid in (select cid from tb\_category where pid=\#\{cid\})
时间紧任务重,暂时没有事件去找根本原因了,先记录一下。
