I have a situation like this: I need to find out the i_chronicle_id of a document. If I try with r_object_id(i.e select i_chronicle_id from dm_document where r_object_id= some id , it will return me the i_chronicle_id. Then no problem. But if someone has modified the document(checked out and checked in) my above query doesn t work because the r_object_id has changed in that situation, which I do not know. Can anyone help me with dql in such a situation?
注:我寻找“i_chronicle_id”的原因,是获得最新数据。
努力做如下事情:
select r_object_id from dm_document
where i_chronicle_id in (
select i_chronicle_id from dm_document (ALL) where r_object_id = ID( ? )
)
