Question

我正在针对IBM Informix数据库运行以下查询并获得ERROR 42000: A syntax error has occurred。 FROM和WHERE子句在其他查询中运行正常，因此我查看SELECT和GROUP BY部分。任何想法语法有什么问题？

SELECT COUNT(DISTINCT "informix".agentconnectiondetail.sessionid) AS calls_abandoned, 
DAY("informix".agentconnectiondetail.startdatetime) AS Expr2

FROM         "informix".agentconnectiondetail, "informix".contactqueuedetail, "informix".contactservicequeue

WHERE     "informix".agentconnectiondetail.sessionid = "informix".contactqueuedetail.sessionid AND 
                      "informix".contactqueuedetail.targetid = "informix".contactservicequeue.recordid AND "informix".contactqueuedetail.disposition = 1 AND 
                      "informix".agentconnectiondetail.startdatetime BETWEEN '2016-10-1 00:00:00' AND CURRENT

GROUP BY DAY("informix".agentconnectiondetail.startdatetime)

目标btw是查找每月中每一天（1-31）发生的唯一呼叫总数（calls_abandoned）。

Answer 1

替换

GROUP BY DAY（＆＃34; informix＆＃34; .agentconnectiondetail.startdatetime）

通过

GROUP BY 2
