【问题描述】：

我正在尝试使用 LISTAGG 合并 sql 中的行，但是得到的错误消息不是按函数分组

select
tbc.idattribute,
tbc.idclient,
tbc.idclientattribute,
tbc.idattributetype,
tbl.vcdescription,
LISTAGG(tb.vclongdescription, \'; \') WITHIN GROUP(ORDER BY tbc.idclient) \" test_consent\",
person_id
from
tbclientattribute tbc, tblookupheader tbl, tbclient, tblookupdetail tb
where tbc.idattributetype = tbl.idlookupheader (+)
and tbclient.idclient = tbc.idclient (+)
and tbc.idattribute = tb.idlookupdetail(+)
group by person_id
order by person_id

请标记您正在使用的数据库。

我不确定合并是什么意思，但是对于该选择语句，您需要在 GROUP BY 中包含所有选定的变量才能使其工作。像这样的东西：

select
tbc.idattribute,
tbc.idclient,
tbc.idclientattribute,
tbc.idattributetype,
tbl.vcdescription,
LISTAGG(tb.vclongdescription, '; ') WITHIN GROUP(ORDER BY tbc.idclient) " test_consent",
person_id
from
tbclientattribute tbc, tblookupheader tbl, tbclient, tblookupdetail tb
where tbc.idattributetype = tbl.idlookupheader (+)
and tbclient.idclient = tbc.idclient (+)
and tbc.idattribute = tb.idlookupdetail(+)
group by person_id, tbc.idattribute,tbc.idclient,tbc.idclientattribute,tbc.idattributetype,tbl.vcdescription
order by person_id;
