ODAC 11.2版本4(11.2.0.3.0)抛出"Oracle 11.2.0.2.0不支持APPLY"异常

Question

我正在使用实体框架与oracle刚刚发布的新ODAC.

我的问题是,我在以前的测试版中工作的一些查询在这个新版本中停止工作.

这是一个例子:

IQueryable<SYS_PERFIL> query1 = m.DBContext.SYS_PERFIL.Where(T => T.SYS_UTILIZADOR.Where(TT => TT.ACTIVO == 1).Count() > 0);

IQueryable<SYS_PERFIL> query2 = m.DBContext.SYS_PERFIL.Where(T => T.SYS_UTILIZADOR.FirstOrDefault(TT => TT.ACTIVO == 1) != null);

string test1Query = ((System.Data.Objects.ObjectQuery)query1).ToTraceString();

string test2Query = ((System.Data.Objects.ObjectQuery)query2).ToTraceString();

var test1 = query1.ToList();

var test2 = query2.ToList();

当test1返回当前结果时,test2抛出一个oracle异常'ORA-00905:missing keyword',并带有消息:'Oracle 11.2.0.2.0不支持APPLY'.

我不想重新测试我的所有方法.有没有办法告诉EF不要使用申请？

以下是EF生成的查询:

test1Query:

SELECT "Project1"."PERFIL_ID" AS "PERFIL_ID" FROM ( SELECT "Extent1"."PERFIL_ID" AS PERFIL_ID", (SELECT COUNT(1) AS "A1" FROM "SMI2012"."SYS_UTILIZADOR" "Extent2" WHERE (("Extent1"."PERFIL_ID" = "Extent2"."PERFIL_ID") AND (1 = "Extent2"."ACTIVO"))) AS "C1"
 FROM "SMI2012"."SYS_PERFIL" "Extent1")  "Project1" WHERE ("Project1"."C1" > 0)

test2Query:

SELECT "Extent1"."PERFIL_ID" AS "PERFIL_ID" FROM  "SMI2012"."SYS_PERFIL" "Extent1" CROSS APPLY  (SELECT "Extent2"."PERFIL_ID" AS "PERFIL_ID", "Extent2"."ACTIVO" AS "ACTIVO", "Extent2"."USER_ID" AS "USER_ID" FROM "SMI2012"."SYS_UTILIZADOR" "Extent2" WHERE (("Extent1"."PERFIL_ID" = "Extent2"."PERFIL_ID") AND (1 = "Extent2"."ACTIVO")) AND (ROWNUM <= (1) ) ) "Element1" WHERE ("Element1"."USER_ID" IS NOT NULL)

提前致谢.

Telerik OpenAccess ORM 不使用 APPLY 语句。我在嵌套组查询上遇到了同样的问题。当我构建 OA 模型时，查询运行得很好！
