如何在C＃中调用oracle函数？ [英] How do I call oracle function in C# ?

问题描述

我有一个oracle函数，它有3个参数并返回有4列的记录。 
 
但是我得到的例外是
 
 ORA-06550：第1行第7列：
 PLS-00221：'get_receipts'不是程序或未定义
 
这是我的代码。 
 
 
 cmd.CommandText =get_receipts; 
 cmd.CommandType = CommandType.StoredProcedure; 
 
 cmd.Parameters.Add（new OracleParameter（p_store_num，store_num））; 
 cmd.Parameters.Add（new OracleParameter（p_create_dt，create_date））; 
 cmd.Parameters.Add（new OracleParameter（p_cc_last4，cc_last4））; 
} 
 
 
 OracleDataReader dr = cmd.ExecuteReader（）; 
 
 while（dr.Read（））
 {
 
 ResponseModel sample = new ResponseModel（）; 
 
 sample.Field1 = dr.GetString（0）; 
 sample.Field2 = dr.GetString（1）; 
 sample.Field3 = dr.GetString（2）; 
 sample.Field4 = dr.GetString（3）; 
 
 response.Add（sample）; 
 
} 

我的尝试：

这是我的代码。 
 
 
 cmd.CommandText =get_receipts; 
 cmd.CommandType = CommandType.StoredProcedure; 
 
 cmd.Parameters.Add（new OracleParameter（p_store_num，store_num））; 
 cmd.Parameters.Add（new OracleParameter（p_create_dt，create_date））; 
 cmd.Parameters.Add（new OracleParameter（p_cc_last4，cc_last4））; 
} 
 
 
 OracleDataReader dr = cmd.ExecuteReader（）; 
 
 while（dr.Read（））
 {
 
 ResponseModel sample = new ResponseModel（）; 
 
 sample.Field1 = dr.GetString（0）; 
 sample.Field2 = dr.GetString（1）; 
 sample.Field3 = dr.GetString（2）; 
 sample.Field4 = dr.GetString（3）; 
 
 response.Add（sample）; 
 
}

问题是没有调用存储过程，问题是SQL drtbrt不知道你的存储过程打电话。

Quote：

ORA-06550：第1行第7列：

PLS-00221：'get_receipts'不是程序或未定义

消息相当明确！

检查SQL服务器上存在哪些存储过程。 />
和正确的程序名称或创建程序。

检查一些事项：



-确保函数编译，你在编译过程中没有收到任何错误信息。



- 如果函数的所有者与调用函数的用户不同，请定义调用中的模式，如[schema]。[procedure]或为函数创建一个同义词。



- 确保调用者对该函数具有 EXECUTE 特权。

< blockquote>嘿伙计们谢谢你们。我问过创建函数的人来存储proc并在我的代码中进行了以下更改。请告诉我是否提供max int size是好的..

 cmd.CommandText =get_receipts; 
 cmd.CommandType = CommandType.StoredProcedure; 
 
 cmd.Parameters.Add（new OracleParameter（p_store_num，store_num））; 
 cmd.Parameters.Add（new OracleParameter（p_create_dt，create_date））; 
 cmd.Parameters.Add（new OracleParameter（p_cc_last4，cc_last4））; 
 cmd.Parameters.Add（new OracleParameter（o_return_cur，OracleDbType.RefCursor， int.MaxValue ，ParameterDirection.Output））; 
 

I have an oracle function,which takes 3 parametes and return records which has four columns. 

But I am getting an exception which is 

ORA-06550: line 1, column 7:
PLS-00221: 'get_receipts' is not a procedure or is undefined

this is my code. 


					cmd.CommandText = "get_receipts";
                    cmd.CommandType = CommandType.StoredProcedure;

                    cmd.Parameters.Add(new OracleParameter("p_store_num", store_num));
                    cmd.Parameters.Add(new OracleParameter("p_create_dt", create_date));
                    cmd.Parameters.Add(new OracleParameter("p_cc_last4", cc_last4));
                }


                OracleDataReader dr = cmd.ExecuteReader();
               
                while (dr.Read())
                {
                   
                    ResponseModel sample = new ResponseModel();

                    sample.Field1 = dr.GetString(0);
                    sample.Field2 = dr.GetString(1);
                    sample.Field3 = dr.GetString(2);
                    sample.Field4 = dr.GetString(3);

                    response.Add(sample);
                   
                }

What I have tried:

this is my code. 


					cmd.CommandText = "get_receipts";
                    cmd.CommandType = CommandType.StoredProcedure;

                    cmd.Parameters.Add(new OracleParameter("p_store_num", store_num));
                    cmd.Parameters.Add(new OracleParameter("p_create_dt", create_date));
                    cmd.Parameters.Add(new OracleParameter("p_cc_last4", cc_last4));
                }


                OracleDataReader dr = cmd.ExecuteReader();
               
                while (dr.Read())
                {
                   
                    ResponseModel sample = new ResponseModel();

                    sample.Field1 = dr.GetString(0);
                    sample.Field2 = dr.GetString(1);
                    sample.Field3 = dr.GetString(2);
                    sample.Field4 = dr.GetString(3);

                    response.Add(sample);
                   
                }

The problem is not calling a stored procedure, the problem is that SQL drtbrt don't know the stored procedure you are calling.

Quote:

ORA-06550: line 1, column 7:
PLS-00221: 'get_receipts' is not a procedure or is undefined

Message is rather explicit!
Check what stored procedure exist on SQL server.
And correct procedure name or create procedure.

Check a few things:

-Ensure that the function compiles, that you don't get any error messages during compilation.

- If the owner of the function is a different user than the ones that calls it, define the schema in the call, like [schema].[procedure] or create a synonym for the function.

- Ensure that the caller has EXECUTE privileges to the function.

Hey guys thank you.. I asked the guy who has created function to store proc and made following changes in my code. please let me know if it is good to provide max int size..

cmd.CommandText = "get_receipts";
cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add(new OracleParameter("p_store_num", store_num));
cmd.Parameters.Add(new OracleParameter("p_create_dt", create_date));
cmd.Parameters.Add(new OracleParameter("p_cc_last4", cc_last4));
cmd.Parameters.Add(new OracleParameter("o_return_cur", OracleDbType.RefCursor,int.MaxValue,ParameterDirection.Output));
