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

 1  /// <summary>

 2         /// 批量插入数据

 3         /// </summary>

 4         /// <param name="table">数据表</param>

 5         /// <param name="targetTableName">数据库目标表名</param>

 6         /// <returns></returns>

 7         public static bool ExcuteBulkData(DataTable table, string targetTableName)

 8         {

 9             bool result = false;

10             using (ODAC.OracleConnection conn = new ODAC.OracleConnection(connStr))

11             {

12                 using (ODAC.OracleBulkCopy bulkCopy = new ODAC.OracleBulkCopy(connStr, ODAC.OracleBulkCopyOptions.Default))

13                 {

14                     if (table != null && table.Rows.Count > 0)

15                     {

16                         bulkCopy.DestinationTableName = targetTableName;

17                         for (int i = 0; i < table.Columns.Count; i++)

18                         {

19                             string col=table.Columns[i].ColumnName;

20                             bulkCopy.ColumnMappings.Add(col, col);

21                         }

22                         conn.Open();

23                         bulkCopy.WriteToServer(table);

24                         result = true;

25                     }

26                 }

27             }

28             return result;

29         }
