我试图解决这个问题，但无济于事。在向包含过程'INSCRAPP'的Oracle包中插入大量数据时出错。错误消息是，
ORA-06550：第1行第7栏： PLS-00306：错误的数量或类型 调用'INSCRAPP'的参数 ORA-06550：第1行第7列：PL / SQL： 声明被忽略

正在重复以下参数。看起来复制粘贴搞砸了。
OracleParameter param_fName_in = new OracleParameter("fName_in", OracleType.VarChar);
OracleParameter param_mi_in = new OracleParameter("mi_in", OracleType.VarChar);
OracleParameter param_lName_in = new OracleParameter("lName_in", OracleType.VarChar);
OracleParameter param_addr1_in = new OracleParameter("addr1_in", OracleType.VarChar);
OracleParameter param_addr2_in = new OracleParameter("addr2_in", OracleType.VarChar);
OracleParameter param_city_in = new OracleParameter("city_in", OracleType.VarChar);

当参数看似匹配时，可能的查询@Rajesh引发了o_cust_id指定的大小，有两种可能性; （1）你确定你正在使用正确的软件包 - 在另一个模式中没有不同的版本，而你可能会采用不同的参数吗？ （2）你专注于参数，但你确定程序调用是正确的吗？也可能有助于发布该代码。
您是否尝试过减少的案例 - 一个带有一个参数的过程 - 以确保它与OracleType.VarChar / VARCHAR2一样有效？
