通过odbc通过dotnet访问oracle存储过程

Question

i have wrote procedures as

CREATE OR REPLACE PROCEDURE proc_ss(cName IN PayRoll.Name%VARCHAR2(50)   
)
IS
BEGIN 
 insert into employees(Name) values(cName);
END;

it executed with some compilation errors through sql plus.

and my c# code for accessing this procedure is

OdbcCommand cmdupd = new OdbcCommand("{call proc_ss(?)}", con);    
            cmdupd.CommandType = CommandType.StoredProcedure;
            cmdupd.Parameters.Add("Name", OdbcType.VarChar, 50).Value = Name;           
            cmdupd.ExecuteNonQuery();
            cmdupd.Dispose();

while running the above query i am getting error as

System.data.odbcexception as:

ERROR [NA000] [Microsoft][ODBC driver for Oracle][Oracle]ORA-20003:
ERROR [42000] [Microsoft][ODBC driver for Oracle]Syntax error or access violation

waiting for your valuable responses and comments..

Answer 1

You adjust command Name with proc_ss

OdbcCommand cmdupd = new OdbcCommand("{ CALL proc_ss(?) }", con);  

And you adjust also your parameter

 cmdupd.Parameters.Add("@cName", OdbcType.VarChar, 50).Value = Name;
