嗨,我正在使用ODP.NET(C#)将对象传递给oracle包中的过程。由于关联数组,我正在使用ODP.NET。我无法在ODP.NET中找到oracledbtype.object来使参数oracledbtype成为对象。我必须使用ODP.NET在.NET端使用哪个dbtype作为参数。
public Oracle.DataAccess.Client.OracleCommand oc = new Oracle.DataAccess.Client.OracleCommand();
oc.Parameters.Add("Param1", OracleDbType.Varchar2).Value = txt_RequestId.Text;
//assign the array to the parm
Oracle.DataAccess.Client.OracleParameter additionalBusiness_AssocParm = new Oracle.DataAccess.Client.OracleParameter();
// When I tried to assign parameter OracleDbType to Varchar2 it is generating an error [PLS-00306: wrong number or types of arguments in call to 'INSERT_REQUEST'].
// When I tried to change that value to Object. It is giving compliation error that object dbtype doesn't exist in Oracle.Data.Client.OracleDbType
additionalBusiness_AssocParm.OracleDbType = Oracle.DataAccess.Client.OracleDbType.Varchar2;
additionalBusiness_AssocParm.CollectionType = Oracle.DataAccess.Client.OracleCollectionType.PLSQLAssociativeArray;
additionalBusiness_AssocParm.Direction = ParameterDirection.Input;
additionalBusiness_AssocParm.Value = unitId; // unitId is an array of User defined type
oc.Parameters.Add(additionalBusiness_AssocParm);
try
{
DoQueryWithODP("TEST_PKG.INSERT_UNIT", true);
}
最佳答案
好的,在没有您的pl / sql规范的情况下,我将尝试解决此问题,但我们将了解其工作原理。
我将使用ODP安装中提供的示例@%ORA_HOME%\ odp.net \ samples \ 2.x \ AssocArray \ AssocArray.sln
作为示例谈话要点。
但这个网站也有帮助
Using PL/SQL Associative Arrays(实际上是mservidio提供的文章中的链接,尽管该文章是关于ArrayBind而不是关联数组的)
CREATE TABLE TestAssociativeArray(COL1 varchar2(20), COL2 varchar2(20)) ;
/
create or replace PACKAGE MyTestAssociativeArray AS
TYPE AssocArrayVarchar2_t is table of VARCHAR(20) index by BINARY_INTEGER;
PROCEDURE TestVarchar2(Param1 IN TestAssociativeArray.COL1%type ,
Param2 IN AssocArrayVarchar2_t);
END MyTestAssociativeArray ;
/
create or replace package body MyTestAssociativeArray as
PROCEDURE TestVarchar2(Param1 IN TestAssociativeArray.COL1%type ,
Param2 IN AssocArrayVarchar2_t)
AS
i INTEGER ;
BEGIN
FOR i in Param2.first..Param2.last LOOP
insert into TestAssociativeArray(col1, col2)
values (Param1 , Param2(i)) ;
END LOOP ;
END TestVarchar2 ;
END MyTestAssociativeArray ;
/
现在为.net代码:
static void Main(string[] args)
{
// Connect
string connectStr = getConnection();
// Setup the Tables for sample
OracleConnection connection = new OracleConnection(connectStr);
OracleCommand cmd = new OracleCommand("MyTestAssociativeArray.TestVarchar2", connection);
cmd.CommandType = CommandType.StoredProcedure ;
OracleParameter param1 = cmd.Parameters.Add("param1", OracleDbType.Varchar2);
OracleParameter param2 = cmd.Parameters.Add("param2", OracleDbType.Varchar2);
// Setup the direction
param1.Direction = ParameterDirection.Input;
param2.Direction = ParameterDirection.Input;
// Specify that we are binding PL/SQL Associative Array
param2.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
param1.Value = "ConstantValue" ;
param2.Value = new string[3]{"Val1",
"Val2",
"Val3"};
try
{
connection.Open();
cmd.ExecuteNonQuery();
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
}
和结果(清理)
select * from TestAssociativeArray
/
COL1 COL2
-------------------- --------------------
ConstantValue Val1
ConstantValue Val2
ConstantValue Val3
/** --clean up
drop package MyTestAssociativeArray;
drop table TestAssociativeArray ;
**/
但是,由于您尚未发布规格,因此可能很简单:
需要:
cmd.BindByName = true;
since ODP by default binds by position AND not by name(这使很多人绊倒)
