java.lang.Integer無法轉換為java.lang.String異常

Question

我在運行mdx查詢時遇到了此錯誤。我真的不明白該錯誤，我再次執行多維數據集很多次，但仍然收到此錯誤！ 這是完全錯誤：

這是查詢：

SELECT {[Measures].[quantita_media], [Measures].[quantita_totale]} ON
COLUMNS,
{([Periodo], [Articolo], [ScontrinoFiscale])} ON ROWS
FROM [Vendite]

這是PostgreSQL模式：

CREATE TABLE data_dt (
    data character varying(10) NOT NULL,
    giorno character varying(10) NOT NULL,
    mese character varying(10) NOT NULL,
    anno character varying(4) NOT NULL
);

CREATE TABLE prodotto_dt (
    nome character varying(30) NOT NULL,
    descrizione character varying(30) NOT NULL
);
CREATE TABLE scontrino_dt (
    codice integer NOT NULL,
    totale integer NOT NULL
);
CREATE TABLE vendita_ft (
    data character varying(10) NOT NULL,
    nome character varying(30) NOT NULL,
    codice integer NOT NULL,
    quantita integer NOT NULL
);
ALTER TABLE ONLY data_dt
    ADD CONSTRAINT data_dt_pkey PRIMARY KEY (data);
ALTER TABLE ONLY prodotto_dt
    ADD CONSTRAINT prodotto_dt_pkey PRIMARY KEY (nome);
ALTER TABLE ONLY scontrino_dt
    ADD CONSTRAINT scontrino_dt_pkey PRIMARY KEY (codice);
ALTER TABLE ONLY vendita_ft
    ADD CONSTRAINT vendita_ft_pkey PRIMARY KEY (data, nome, codice);
ALTER TABLE ONLY vendita_ft
    ADD CONSTRAINT vendita_ft_codice_fkey FOREIGN KEY (codice) REFERENCES scontrino_dt(codice);
ALTER TABLE ONLY vendita_ft
    ADD CONSTRAINT vendita_ft_data_fkey FOREIGN KEY (data) REFERENCES data_dt(data);
ALTER TABLE ONLY vendita_ft
    ADD CONSTRAINT vendita_ft_nome_fkey FOREIGN KEY (nome) REFERENCES prodotto_dt(nome);

這是由架構工作台生成的我的xml多維數據集：

Answer 1

我想我找到了。 在表“ scontrino_dt”中，將“ codice”和“ totale”聲明為Integer。

CREATE TABLE scontrino_dt (
    codice integer NOT NULL,
    totale integer NOT NULL
);

但是，在您的XML中，將“ codice”設置為String！

<Level name="codice" table="scontrino_dt" column="codice" nameColumn="codice" type="String" uniqueMembers="false" levelType="Regular" hideMemberIf="Never">
</Level>
<Level name="totale" table="scontrino_dt" column="totale" nameColumn="totale" type="Integer" uniqueMembers="false" levelType="Regular" hideMemberIf="Never">
</Level>

Answer 2

您所使用的大多數技術都不熟悉，因此如果沒有幫助，請原諒。

對我來說，這條mdx細節太少了：

{([Periodo], [Articolo], [ScontrinoFiscale])} ON ROWS

通常，在mdx中，您需要聲明要顯示的級別或層次結構，而上面的內容似乎只是維名稱。 請先嘗試用上面的內容替換上面的行：

{[Periodo].[giorno].MEMBERS} ON ROWS

也許這：

{[Periodo].[tempo].[giorno].MEMBERS} ON ROWS

還是會出錯？ 如果沒有，那么有幾個hiearchies ON ROWS你需要找出執行的方式cross join在蒙德里安-在ssas它是通過完成*操作：

 {[Periodo].[tempo].[giorno].MEMBERS 
* [Articolo].[prodotto].[nome].MEMBERS} ON ROWS

在蒙德里安，也許您需要使用CROSSJOIN函數：

 CROSSJOIN(
    [Periodo].[tempo].[giorno].MEMBERS 
   ,[Articolo].[prodotto].[nome].MEMBERS) ON ROWS
