JPA请求出错

Question

我有一个产生错误的EJBQL请求：

EJBQL请求：

javax.persistence.Query multipleSelect= em.createQuery("SELECT p.pname,j.descriptor from Project p LEFT OUTER JOIN Nodeassociation n  ON p.id=n.sourceNodeId and n.sinkNodeEntity='WorkflowScheme' LEFT OUTER JOIN Workflowscheme w  ON n.sourceNodeId = w.id LEFT OUTER JOIN Jiraworkflows j ON w.name=j.workflowname; " );

错误：

line 1:244 mismatched character ' ' expecting set ''..''
An exception occurred while creating a query in EntityManager: 
Exception Description: Syntax error parsing the query [SELECT p.pname,j.descriptor   from Project p LEFT OUTER JOIN Nodeassociation n  ON p.id=n.sourceNodeId and n.sinkNodeEntity='WorkflowScheme' LEFT OUTER JOIN Workflowscheme w  ON n.sourceNodeId = w.id LEFT OUTER JOIN Jiraworkflows j ON w.name=j.workflowname; ].
 Internal Exception:   org.eclipse.persistence.internal.libraries.antlr.runtime.EarlyExitException

更新 去除半音后：
