观看 .net-Oracle 存储过程调用以查看参数列表

Question

我想知道是否有某种方法可以查看从 .net 方法调用的存储过程的参数列表。我不断收到一个

PLS-00306: wrong number or types of arguments in call to 'SPPUT_FOCUSEDREADMIT'

ORA-06550：第 1 行，第 7 列

每当我调用我的存储过程时都会出现异常。我查看了为拨打电话而设置的对象，似乎我设置正确。我知道我要展示代码来证明这一点，我会大声疾呼，但我循环遍历一个 XML 文档来填充 ODP.net 的 cmd.Parameters 对象......所以我只会向你展示我的数组使用 XPath 到正确的节点和存储过程的参数列表...无需显示所有代码...

string[] paths = new string[31];
        paths[0] = "EncounterId";
        paths[1] = "PopulationPatientID";
        paths[2] = "EMPIID";
        paths[3] = "Active";
        paths[4] = "FirstName";
        paths[5] = "LastName";
        paths[6] = "DateOfBirth";
        paths[7] = "Phone";
        paths[8] = "HospitalFinNumber";
        paths[9] = "AdmitDate";
        paths[10] = "MRNType";
        paths[11] = "MRN";
        paths[12] = "PatientRoomPhone";

        paths[14] = "DischargeDisposition";
        paths[15] = "DischargeTo";
        paths[16] = "DischargeAdvocateCall";
        paths[17] = "Payor";
        paths[18] = "HomeHealthCareAccepted";
        paths[19] = "SafeLandingAccepted";
        paths[20] = "PCPName";

        paths[29] = "CompletedPathwayReason";
        paths[30] = "Comment";

        string[] colName = new string[31];
        colName[0] = "FOCUSED_READMISSIONS_IDIn";
        colName[1] = "POPULATION_PATIENT_IDIn";
        colName[2] = "EMPIin";
        colName[3] = "ACTIVEIn";
        colName[4] = "FIRST_NAMEin";
        colName[5] = "LAST_NAMEin";
        colName[6] = "DOBin";
        colName[7] = "PHONEin";

        colName[10] = "MRN_TYPEin";
        colName[11] = "MRNin";
        colName[12] = "PATIENT_ROOM_PHONEin";
        colName[13] = "DISCHARGE_DATEin";
        colName[14] = "DISCHARGE_DISPOSITIONin";

        colName[16] = "DISCHARGE_ADVOCATE_CALLin";
        colName[17] = "PAYORin";
        colName[18] = "HOME_HEALTHCARE_ACCEPTEDin";
        colName[19] = "SAFE_LANDING_ACCEPTEDin";
        colName[20] = "PCP_NAMEin";
        colName[21] = "PCP_PHONEin";
        colName[22] = "SPECIALIST_NAMEin";
        colName[23] = "SPECIALIST_PHONEin";
        colName[24] = "PCP_APPOINTMENT_DATETIMEin";
        colName[25] = "PCP_APPOINTMENT_LOCATIONin";
        colName[26] = "SPECIALIST_APPT_DATETIMEin";
        colName[27] = "SPECIALIST_APPT_LOCATIONin";

        colName[29] = "COMPLETED_PATHWAY_REASONin";
        colName[30] = "COMMENTSin";

这里是存储过程的参数列表...

FOCUSED_READMISSIONS_IDIn   NUMBER,
POPULATION_PATIENT_IDIn     NUMBER,
EMPIin                      VARCHAR2,

但是那段代码是无关紧要的。当我从 .net 函数调用存储过程时，如何查看发送到存储过程的内容。因为当我从 sql Developer 调用它时，它似乎工作得很好。

Answer 1

实际上，我在 Oracle 参数列表中计算了 32 个参数，而您只用 31 个参数来调用它。这并不能真正回答问题，而是导致您出错的原因。

有很多方法可以从 Oracle 中找出参数列表。你可以使用describe或者存储过程dbms_metadata，dbms_describe；然后是系统表和视图，all_procedures、user_arguments 等。

user_arguments 可能是最有可能对您有用的一个。
