需要很长时间才能在SQL Server 2008 R2中插入行

Question

我在c＃Winforms gridview中有超过200,000条记录，大约需要一个小时才能插入到我的数据库中。 我正在尝试改善此插入的性能。 我希望在5到10分钟内插入所有记录。

我正在使用For循环填充每一行以通过SQL事务插入数据库，我不认为SqlBulkCopy会成功，因为所有200,000条记录都需要在插入数据库之前通过DB进行验证。

通常，您可以通过将数据批量插入[一个]工作表中来将数据分段存储到数据库中，而无需参照完整性或任何东西-只需原始数据加上您可能需要的任何[非唯一]索引即可。 一旦上演了，您可以：

• 根据数据库验证工作表中的数据，并
• 将其应用于相关的“实际”表格。
