.NET Core 项目中使用数组绑定的无效参数绑定 Oracle C#

问题描述

我想使用数组绑定将批量数据插入到 oracle 表中。

操作代码，抛出异常。

IList<DetailsDto> detailsListDto = new List<DetailsDto>();

query = @"INSERT INTO t115_allocdetails (c115_storeno,c115_itemno,c115_id) VALUES (:c115_storeno,:c115_itemno,:c115_id)";

long[] ids = new long[allocationDetails.Count];
long[] stores = new long[allocationDetails.Count];
string[] itemnumbers = new string[allocationDetails.Count];

for (int j = 0; j < allocationDetails.Count; j++)
{
     ids[j] = Convert.ToInt64(allocationDetails[j].Id);
     stores[j] = Convert.ToInt64(allocationDetails[j].Item.StoreNumber);
     itemnumbers[j] = Convert.ToString(allocationDetails[j].Item.ItemNumber);
}

 OracleParameter c115_storeno = new OracleParameter();
 c115_storeno.OracleDbType = OracleDbType.Int64;
 c115_storeno.Value = stores;

 OracleParameter c115_itemno = new OracleParameter();
 c115_itemno.OracleDbType = OracleDbType.Varchar2;
 c115_itemno.Value = itemnumbers;

 OracleParameter c115_id = new OracleParameter();
 c115_id.OracleDbType = OracleDbType.Int64;
 c115_id.Value = ids;

 using (var command = dbCon.CreateCommand())
 {
     command.CommandText = query;
     command.CommandType = CommandType.Text;
     command.BindByName = true;
     command.ArrayBindCount = detailsListDto.Count;

     command.Parameters.Add(c115_storeno);
     command.Parameters.Add(c115_itemno);
     command.Parameters.Add(c115_id);
     await command.ExecuteNonQueryAsync();
       }

System.ArgumentException：参数绑定无效（参数“c115_storeno”）

更新答案

我在每个 oracle 参数中添加了以下属性，并已解决。

    c115_storeno.Direction = ParameterDirection.Input;
    c115_storeno.ParameterName = ":c115_storeno";
    c115_itemno.Direction = ParameterDirection.Input;
    c115_itemno.ParameterName = ":c115_itemno";
    c115_id.Direction = ParameterDirection.Input;
    c115_id.ParameterName = ":c115_id";
