Kuv los yuam ib tug BDC kev no lub limtiam uas manifested nws tus kheej rau cov neeg siv interface thiab ua tus 12 nas muv cav Thaum runtime.

Ua ntej, qhov no nyob hauv cov neeg interface:

Kuj tsis paub liaj teb mus tau ntxig yaam tseem ceeb txhua lub Identifier nuav los yog txim tuag SpecificFinder MethodInstance nrog lub npe … Xyuas input tsis tau nrog txhua Identifier uas sau tseg rau qhov chaw no TypeDescriptors.

Ntawm no yog ib qho screen txhaj:

Kuv tseem ua txoj xov tshwm nyob rau lub 12 nas muv ca thaum yuav (siv kuv patented high-tech-don't-try-this-at-home uas "mysterious tsis" txujci):

Kuv nrhiav ib ncig thiab nrhiav tau tej yam ua nyob rau hauv lub Rooj sab laj MSDN, tab sis lawv tsis txaus kuv nkag siab kuv yog ua dab tsis ncaj ncees lawm. Kuv saib ib webcast los Ted Pattison uas kuv niaj hnub muaj squirreled mus rau ib tug neeg rau zaub mov thiab tuaj kom paub kuv qhov teeb meem.

Nyob rau hauv kuv ADF, Kuv yuav siv rau ib SQL database li:

            <Khoom Lub npe="RdbCommandText" Hom="System.String">
              <![CDATA[
                XAIV SETID, CARRIER_ID, EFFDT, DESCR, EFF_STATUS, TAXPAYER_ID, NETWORK_ID, FRT_FORWARD_FLG, ALT_NAME1, ALT_NAME2, LANGUAGE_CD,
                      LUB TEB CHAWS, ADDRESS1, ADDRESS2, ADDRESS3, ADDRESS4, LUB ZOS, NUM1, NUM2, HOUSE_TYPE, ADDR_FIELD1, ADDR_FIELD2, ADDR_FIELD3,
                      CHEEB NROOG, LUB XEEV, KOJ, GEO_CODE, IN_CITY_LIMIT, COUNTRY_CODE, XOV TOOJ, EXTENSION, FAX MUS, LAST_EXP_CHK_DTTM, FREIGHT_VENDOR,
                      INTERLINK_DLL, TMS_EXCLUDE_FLG los dbo.PS_CARRIER_ID_VW nrog (nolock)
                QHOV TWG
                  (SETID <> 'FEEM') thiab
                  (qis(CARRIER_ID) >= sab(@MinId)) thiab
                  (qis(CARRIER_ID) <= sab(@MaxId)) thiab
                  (qis(DESCR) NYIAM sab(@InputDescr))
                ]]>
            </Khoom>

Kuv tau muab qhov SQL los ntawm ib tug neeg DBA thiab kuv muab kuv mus nkag siab hais tias nws yog ib tug tshwj xeeb saib lawv tsim cia rau kuv. Cov yuam sij nws yog CARRIER_ID.

Ntawm no yog cov yoov nkag tau kuv:

      <Identifiers>
        <Identifier Lub npe="CARRIER_ID" TypeName="System.String" />
        <Identifier Lub npe="DESCR" TypeName="System.String" /> 
      </Identifiers>

Qhov chaw nyob ntawm kab, Kuv tswj tau rau kuv tus kheej lawm lub ntsiab ntawm yam <Identifiers> thiab ntxiv DESCR txawm tias tsis tau ib identifier. Kuv muab DESCR lub teeb identifiers thiab presto! Nws cov ua haujlwm.

I hope this saves someone some grief 🙂
