@wenshao 你好，想跟你请教个问题：
druid的sql parser好像不支持oracle的这种语法：
listagg(odoffer.offer_name,',') within GROUP(ORDER BY odoffer.offer_name)
会报错：

麻烦看一看这个问题，谢谢！
写回答
把完整的SQL发出来吧，我好做测试和支持listagg(odoffer.offer_name,',')withinGROUP(ORDERBYodoffer.offer_name)这个语法是ORACLE11gr2才支持的语法。或于此有关！ select
ohoh.idid,
listagg(odoffer.offer_name,',')withingroup(orderbyodoffer.offer_name)offerNames
FROM ohohoh
LEFTJOINood odofferONohoh.id=odoffer.order_id
WHERE ohoh.create_time >=to_date(?,'yyyy-mm-ddhh24:mi:ss')
groupby
ohoh.id,
listagg(odoffer.offer_name,',')withingroup(orderbyodoffer.offer_name)offerNames
