Python SQL不匹配的输入“Orion”应为“FROM”

Question

我正在使用OrionSDK，我有一个python查询不断返回这个错误：不匹配的输入'Orion'期望'FROM'。这是问题所在。不确定是什么原因造成的。提前谢谢

'''results = swis.query("SELECT "
                 "n.Caption AS NodeCaption"
                 ",n.IP_Address AS IPAddress"
                 ",n.NodeID"
                 ",a.ApplicationID"
                 ",n.Uri AS NodeUri"
                 ",n.Uri AS AppUri"
                 "FROM Orion.Nodes n"
                 "JOIN Orion.APM.Application a ON n.NodeID = a.NodeID"
                 "JOIN Orion.APM.ApplicationTemplate at ON a.ApplicationTemplateID = at.ApplicationTemplateID"
                 "WHERE at.Name IN('Process_Monitor - Dynatrace Linux OneAgent', 'Service_Monitor - Dynatrace "
                 "OneAgent Service'") '''

Answer 1

查询字符串中需要一些额外的空格

例如，这两行：

             ",n.Uri AS AppUri"
             "FROM Orion.Nodes n"

将产生：

,n.Uri AS AppUriFROM Orion.Nodes n

因此，它将“AppUriFROM”解析为列别名；然后，它需要一个FROM关键字，但需要查找Orion，这会导致错误

我认为您需要在FROM、JOIN和WHERE关键字之前添加一个空格
