我把程序写成

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

它通过 sql plus 执行时出现了一些编译错误。

我用于访问此过程的 c# 代码是

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();

在运行上述查询时，我收到错误

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

我不知道我被困在哪里......！

等待您的宝贵回复和意见..

你command Name用 proc_ss调整

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

你也调整你的参数

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