Oracle 用户定义聚合函数的问题
我在聚合 udfs 上遇到了这个恼人的问题,它总是无法调用迭代方法。我的代码就像网络上的其他示例一样(包括 oracle docs 和 Asktom 上的示例)。我尝试更改 UDF 类型,但每次都会发生同样的情况。它说:
ORA-29925: cannot execute DBAODB.WMCONCATROUTINES.ODCIAGGREGATEITERATE
ORA-06553: PLS-306: wrong number or types of arguments in call to 'ODCIAGGREGATEITERATE'
Oracle 版本是 11.1.0.7.0,这是我的代码:
CREATE OR REPLACE TYPE WmConcatRoutines as object (
tmpData number,
STATIC FUNCTION ODCIAggregateInitialize( wmInst IN OUT WmConcatRoutines) RETURN number,
MEMBER FUNCTION ODCIAggregateIterate(wmInst IN OUT WmConcatRoutines, value number) return number,
MEMBER FUNCTION ODCIAggregateMerge(wmInst IN OUT WmConcatRoutines, wmInst2 IN WmConcatRoutines) return number,
MEMBER FUNCTION ODCIAggregateTerminate(wmInst IN WmConcatRoutines, returnValue OUT number, flags IN number) return number
);
/
CREATE OR REPLACE TYPE BODY WmConcatRoutines IS
STATIC FUNCTION ODCIAggregateInitialize( wmInst IN OUT WmConcatRoutines) RETURN number IS
BEGIN
wmInst := WmConcatRoutines(0);
return ODCIConst.Success;
END;
MEMBER FUNCTION ODCIAggregateIterate(wmInst IN OUT WmConcatRoutines, value number) return number IS
BEGIN
wmInst.tmpData := wmInst.tmpData + value;
return ODCIConst.Success;
END;
MEMBER FUNCTION ODCIAggregateTerminate(wmInst IN WmConcatRoutines, returnValue OUT number, flags IN number) return number IS
BEGIN
returnValue := wmInst.tmpData;
return ODCIConst.Success;
END;
MEMBER FUNCTION ODCIAggregateMerge(wmInst IN OUT WmConcatRoutines, wmInst2 IN WmConcatRoutines) return number IS
BEGIN
wmInst.tmpData := wmInst.tmpData + wmInst2.tmpData;
return ODCIConst.Success;
END;
END;
/
CREATE OR REPLACE FUNCTION WM_CONCAT_test (input number) RETURN number
parallel_enable
AGGREGATE USING WmConcatRoutines;
/
关于可能导致此问题的任何想法?提前致谢
I'm having this annoying issue with aggregate udfs where it always fails to invoke the iteration method. My code is just like the other examples around the web (including the ones on oracle docs and asktom). I tried to change the UDF type and the same happens everytime. It says:
ORA-29925: cannot execute DBAODB.WMCONCATROUTINES.ODCIAGGREGATEITERATE
ORA-06553: PLS-306: wrong number or types of arguments in call to 'ODCIAGGREGATEITERATE'
Oracle version is 11.1.0.7.0 and Here's my code:
CREATE OR REPLACE TYPE WmConcatRoutines as object (
tmpData number,
STATIC FUNCTION ODCIAggregateInitialize( wmInst IN OUT WmConcatRoutines) RETURN number,
MEMBER FUNCTION ODCIAggregateIterate(wmInst IN OUT WmConcatRoutines, value number) return number,
MEMBER FUNCTION ODCIAggregateMerge(wmInst IN OUT WmConcatRoutines, wmInst2 IN WmConcatRoutines) return number,
MEMBER FUNCTION ODCIAggregateTerminate(wmInst IN WmConcatRoutines, returnValue OUT number, flags IN number) return number
);
/
CREATE OR REPLACE TYPE BODY WmConcatRoutines IS
STATIC FUNCTION ODCIAggregateInitialize( wmInst IN OUT WmConcatRoutines) RETURN number IS
BEGIN
wmInst := WmConcatRoutines(0);
return ODCIConst.Success;
END;
MEMBER FUNCTION ODCIAggregateIterate(wmInst IN OUT WmConcatRoutines, value number) return number IS
BEGIN
wmInst.tmpData := wmInst.tmpData + value;
return ODCIConst.Success;
END;
MEMBER FUNCTION ODCIAggregateTerminate(wmInst IN WmConcatRoutines, returnValue OUT number, flags IN number) return number IS
BEGIN
returnValue := wmInst.tmpData;
return ODCIConst.Success;
END;
MEMBER FUNCTION ODCIAggregateMerge(wmInst IN OUT WmConcatRoutines, wmInst2 IN WmConcatRoutines) return number IS
BEGIN
wmInst.tmpData := wmInst.tmpData + wmInst2.tmpData;
return ODCIConst.Success;
END;
END;
/
CREATE OR REPLACE FUNCTION WM_CONCAT_test (input number) RETURN number
parallel_enable
AGGREGATE USING WmConcatRoutines;

Any ideas on what may be causing this? thanks in advance

ODCI 函数实现中的参数名称必须与 文档;因此您必须使用
sctx
、self
和ctx2
而不是wminst
和wminst2
>。编辑 正如 APC 简要提到的,似乎只需要
self
;您可以使用其他东西来代替sctx
和ctx2
。我找不到文档参考...编辑 2 是的,我可以... APC 对其作为对象的引用使我想到 此。
The parameter names in your implementations of the ODCI functions have to match those in the documentation; so you have to use
sctx
,self
, andctx2
rather thanwminst
andwminst2
.Edit As APC briefly mentioned, it only seems to be
self
that is required; you can use something else in place ofsctx
andctx2
. I can't find a documentation reference...Edit 2 Yes, I can... APC's reference to it being an object thing led me to this.
