OracleBulkCopy批量插入数据

1、OracleBulk程序集引用using ODAC = Oracle.DataAccess.Client

2、有时候不做字段映射，会使导入的数据出错

上代码

  /// <summary>
         /// 批量插入数据
         /// </summary>
         /// <param name="table">数据表</param>
         /// <param name="targetTableName">数据库目标表名</param>
         /// <returns></returns>
         public static bool ExcuteBulkData(DataTable table, string targetTableName)
         {
             bool result = false;
             using (ODAC.OracleConnection conn = new ODAC.OracleConnection(connStr))
             {
                 using (ODAC.OracleBulkCopy bulkCopy = new ODAC.OracleBulkCopy(connStr, ODAC.OracleBulkCopyOptions.Default))
                 {
                     if (table != null && table.Rows.Count > )
                     {
                         bulkCopy.DestinationTableName = targetTableName;
                         for (int i = ; i < table.Columns.Count; i++)
                         {
                             string col=table.Columns[i].ColumnName;
                             bulkCopy.ColumnMappings.Add(col, col);
                         }
                         conn.Open();
                         bulkCopy.WriteToServer(table);
                         result = true;
                     }
                 }
             }
             return result;
         }
