我正在SqlClient.SqlBulkCopy
尝试将 csv 文件批量复制到数据库中。调用 ..WriteToServer 方法后出现以下错误。
“来自数据源的字符串类型的给定值无法转换为指定目标列的十进制类型。”
这是我的代码,
dt.Columns.Add("IsDeleted", typeof(byte));
dt.Columns.Add(new DataColumn("CreatedDate", typeof(DateTime)));
foreach (DataRow dr in dt.Rows)
{
if (dr["MobileNo2"] == "" && dr["DriverName2"] == "")
{
dr["MobileNo2"] = null;
dr["DriverName2"] = "";
}
dr["IsDeleted"] = Convert.ToByte(0);
dr["CreatedDate"] = Convert.ToDateTime(System.DateTime.Now.ToString());
}
string connectionString = System.Configuration.ConfigurationManager.
ConnectionStrings["connectionString"].ConnectionString;
SqlBulkCopy sbc = new SqlBulkCopy(connectionString);
sbc.DestinationTableName = "DailySchedule";
sbc.ColumnMappings.Add("WirelessId", "WirelessId");
sbc.ColumnMappings.Add("RegNo", "RegNo");
sbc.ColumnMappings.Add("DriverName1", "DriverName1");
sbc.ColumnMappings.Add("MobileNo1", "MobileNo1");
sbc.ColumnMappings.Add("DriverName2", "DriverName2");
sbc.ColumnMappings.Add("MobileNo2", "MobileNo2");
sbc.ColumnMappings.Add("IsDeleted", "IsDeleted");
sbc.ColumnMappings.Add("CreatedDate", "CreatedDate");
sbc.WriteToServer(dt);
sbc.Close();
在visual studio开发服务器下运行时没有错误,但是在iis下运行时却给了我一个错误.....
这是我的 sql server 表详细信息,
[Id] [int] IDENTITY(1,1) NOT NULL,
[WirelessId] [int] NULL,
[RegNo] [nvarchar](50) NULL,
[DriverName1] [nvarchar](50) NULL,
[MobileNo1] [numeric](18, 0) NULL,
[DriverName2] [nvarchar](50) NULL,
[MobileNo2] [numeric](18, 0) NULL,
[IsDeleted] [tinyint] NULL,
