java - 使用 JDBC 执行 SQL 查询时出现异常

Question

在 NetBeans IDE 上使用 jdbc 执行 SQL 查询时出现异常。我能够使用 Microsoft SQL Server Management Studio Express 执行相同的查询，不会出现任何错误。

这是查询:

SELECT tcd.RouterCallKey,adc.AgentSkillTargetID,adc.AgentPeripheralNumber,adc.InstrumentPortNumber,adc.ANI,adc.DateTime,adc.TalkTime 
FROM Termination_Call_Detail tcd 
INNER JOIN 
(
SELECT tcd1.RouterCallKey, AgentSkillTargetID,AgentPeripheralNumber,InstrumentPortNumber,ANI,DateTime,TalkTime
FROM Termination_Call_Detail AS tcd1 WHERE tcd1.AgentSkillTargetID <>'' 
AND tcd1.TalkTime > 0 AND tcd1.TalkTime <=5 AND RouterCallKey <> 0 AND CallDisposition <>28
AND tcd1.DateTime >= '2011-02-03 12:00:00 AM' AND tcd1.DateTime <= '2011-02-03 11:59:59 PM'
) adc 
ON adc.RouterCallKey = tcd.RouterCallKey AND tcd.CallDisposition in (52) 
AND tcd.DateTime >= '2011-02-03 12:00:00 AM' AND tcd.DateTime <= '2011-02-03 11:59:59 PM' 
AND LEN(tcd.ANI ) > 4

这是一个异常(exception):

关键字“as”附近的语法不正确。

两个查询之间必定存在差异。运行 SQL Server Profiler 来捕获查询或执行 System.out.println 来显示您在 Java 中运行的确切查询。留意诸如缺少空格之类的事情，如下所示:

"SELECT * FROM" +
"WHERE problem = 'No space between from and where'";
