Question

当我执行以下原生查询时：

String sql="merge into omfx.OM_PART_LOOKUP   toLookup\r\n" + 
        "           using omfx.OM_PART_LOOKUP fromLookup\r\n" + 
        "               on(\r\n" + 
        "                 toLookup.PROJECT_ID= "+toProjectID+" and \r\n" + 
        "                 fromLookup.PROJECT_ID= "+fromProjectId +" and  \r\n" + 
        "                 toLookup.scope =0 and \r\n" + 
        "                 UPPER(toLookup.PN)  =  UPPER(fromLookup.PN) and\r\n" + 
        "                 UPPER(toLookup.MAN)  =  UPPER(fromLookup.MAN)\r\n" + 
        "                )\r\n" + 
        "           when matched then update \r\n" + 
        "               set \r\n" + 
        "             \r\n" + 
        "             toLookup.SEPN = fromLookup.SEPN ,\r\n" + 
        "             toLookup.SE_MAN_ID = fromLookup.SE_MAN_ID ,\r\n" + 
        "             toLookup.COM_ID = fromLookup.COM_ID ,\r\n" + 
        "             toLookup.SE_MAN_NAME = fromLookup.SE_MAN_NAME ,\r\n" + 
        "             toLookup.PART_CATEGORY = fromLookup.PART_CATEGORY \r\n" + 
        "             \r\n" + 
        "             \r\n" + 
        "            when NOT matched then \r\n" + 
        "            insert (PN,MAN,SEPN, SE_MAN_ID, COM_ID,SE_MAN_NAME ,PART_CATEGORY ,INSERT_DATE,PROJECT_ID)\r\n" + 
        "             values (fromLookup.PN,fromLookup.MAN,fromLookup.SEPN, fromLookup.SE_MAN_ID, fromLookup.COM_ID , fromLookup.SE_MAN_NAME ,fromLookup.PART_CATEGORY , SYSDATE,"+toProjectID+") where\r\n" + 
        "             fromLookup.PROJECT_ID = "+fromProjectId+" and fromLookup.scope = 0\r\n" + 
        "            ";

    System.out.println("projectOperationsBean.mergeManLookup()::sql=="+sql);
     em.createNativeQuery(sql).getSingleResult();

我发现了以下错误

本地异常堆栈：异常[EclipseLink-4002]（Eclipse Persistence Services - 2.4.2.v20130514-5956486）：org.eclipse.persistence.exceptions.DatabaseException 内部异常：java.sql.SQLException：ORA-00900：无效的SQL语句

错误代码：0

但是当我在oracle中执行此查询时，它运行良好

是否支持hibernate运行MERGE语句？

感谢@Jorge Campos

MERGE是一个DML语句，所以我必须执行.executeUpdate()而不是.getSingleResult()

是否hibernate支持运行MERGE语句？
