我在Oracle中使用了存储过程。如何在C＃代码中使用SP的参数？
我使用以下代码：
OracleSP
PROCEDURE TABMPWORKREQUEST_INS(INTWORKREQUEST_ IN NUMBER, VCWORKREQUESTNUMBER_ OUT VARCHAR2,
INTREQUESTEDBY_ IN NUMBER, INTWORKTYPE_ IN NUMBER,INTACTIONTYPE_ IN NUMBER,
INTPRIORITY_ IN NUMBER, INTRECORDID_ IN NUMBER, INTPERMITREQUIRED_ IN NUMBER, VCINSPECTIONREQUIRED_ IN CHAR,
VCLASTUSERID_ IN VARCHAR2, INTCOSTCENTRECODE_ IN NUMBER, VCBUDGETHEAD_ IN VARCHAR2
, VCREFERENCEWORKORDERNUMBER_ IN VARCHAR2, VCJOBDESCRIPTION_ IN VARCHAR2,
VCSTATUS_ IN CHAR, VCHISTORYFLAG_ IN CHAR, VCREASONCODE_ IN VARCHAR2
, VCMSSNUMBER_ IN VARCHAR2, INTAUTHORIZELEVEL_ IN NUMBER, INTPRINTFLAG_ IN NUMBER,
INTINSPECTIONFLAG_ IN NUMBER, INTDAYNUMBER_ IN NUMBER, INTDURATION_ IN NUMBER, INTPROGRESS_ IN NUMBER,
INTWORKSHOPFLAG_ IN CHAR)
IS
EXISTANCE number;
UID_ VARCHAR(5);
SS varchar2(20);
BEGIN
SELECT COUNT(*) into EXISTANCE FROM TABMPWORKREQUEST WHERE INTWORKREQUEST = INTWORKREQUEST_ ;
IF VCLASTUSERID_ = '0' THEN
UID_ := 'U2';
ELSE
UID_ := VCLASTUSERID_;
END IF;
select GetWorkOrderNumber(INTREQUESTEDBY_) INTO SS from dual ;
VCWORKREQUESTNUMBER_ :=SS;
INSERT INTO TABMPWORKREQUEST
VALUES( CMMS.SEQTABMPWORKREQUEST.NEXTVAL , SS , sysdate , INTrequestedby_ ,
INTworktype_ , INTactiontype_ , INTpriority_ , Intrecordid_ , Intpermitrequired_ , Vcinspectionrequired_ ,
Vclastuserid_ , SYSDATE , sysdate , INTcostcentrecode_ , Vcbudgethead_ , sysdate ,
Vcreferenceworkordernumber_ , Vcjobdescription_ , '01' , Vchistoryflag_ , Vcreasoncode_ ,
sysdate , sysdate , Vcmssnumber_ , Intauthorizelevel_ , Intprintflag_ , Intinspectionflag_ ,
Intdaynumber_ , Intduration_ , Intprogress_ , Intworkshopflag_ );
END TABMPWORKREQUEST_INS;
和c＃代码

但是我收到以下错误：
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'TABMPWORKREQUEST_INS'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
如何解决此问题？
答案 0 :(得分：1)
不推荐使用与Oracle相关的MSFT System.Data命名空间中的对象：
http://msdn.microsoft.com/en-us/library/77d8yct7.aspx
但是有一个通用的System.Data.OleDB命名空间：
http://msdn.microsoft.com/en-us/library/system.data.oledb.oledbparameter.direction(v=VS.71).aspx
Command对象有一个参数集合。每个参数都有几个属性，包括direction属性。将该属性设置为输出时，可以在发出命令后检查其值。
Oracle的第三方提供商应该提供类似的东西。
P.S。我在很长一段时间内没有使用过OleDB命名空间 - 但是请记住，参数必须按照它们在SP签名中出现的顺序添加到Parameters集合中。请务必为每个参数设置适当的数据类型，并提供传递的任何文本值的长度。
P.P.S。看起来好像你要将两个相同的参数添加到集合中;其中一个应该被评论出来？
cmd.Parameters.AddWithValue("VCWORKREQUESTNUMBER_",fieldsMpWORKREQUEST.VCWORKREQUESTNUMBER).Direction=ParameterDirection.Output;
OracleParameter requestNo = new OracleParameter();
requestNo.ParameterName = "VCWORKREQUESTNUMBER_";
requestNo.OracleType = OracleType.VarChar;
requestNo.Size = 14;
requestNo.Direction = ParameterDirection.Output;
cmd.Parameters.Add(requestNo);
