Question

我想使用create-or-extend-tables，但eclipselink在创建表后会给出以下错误。我使用的是Eclipselink 2.5.2，db是MS Sql 2014

异常[EclipseLink-4002]（Eclipse持久性服务 - 2.5.2.v20140319-9ad6abd）：org.eclipse.persistence.exceptions.DatabaseException内部例外：com.microsoft.sqlserver.jdbc.SQLServerException： 'announcementCOMPANY_ID'对象已存在。错误代码：2714致电： ALTER TABLE公告ADD CONSTRAINT announcementCOMPANY_ID FOREIGN KEY（COMPANY_ID）REFERENCES公司（ID）查询： DataModifyQuery（sql =“ALTER TABLE announcement ADD CONSTRAINT announcementCOMPANY_ID FOREIGN KEY（COMPANY_ID）参考公司（ID）“）
