将行添加到“将SQL Server 2008查询分解为批”

在的帮助下，我成功地使用bcp导出到平面文件

现在，我想为每个批次添加一到两行。这需要抵消$amount总额，以便每个批次的余额为零。例如，我在一个表中有2501条记录。2500美元的金额为100美元，全部记入账户70000，总计250000美元。最后一条记录2501记入账户80000，价值250000美元；因此，表中的总余额

因为我们的新系统只允许最多950行的批处理，所以我必须使用上面链接的代码分割输出。顺便说一句，效果很好。但是由于每个批次都必须平衡到零，因此我需要在每个批次中添加一行，并将其设置为抵销科目80000，例如

我希望这对某人有意义！；-]关于在何处/何时插入记录的建议，以及我可以在创建每个批之后或之前插入记录吗

谢谢

看起来您应该在创建每个批次后插入新记录。还有一个建议，你链接的帖子使用的是“插入表格…选择…”，比“选择…”慢。。。“进桌子”。“选择进入表格”将自动为您创建表格。在每个批次bcp输出成功后，您可以删除自动创建的表。您还可以使用历史记录表来记住您所做的事情

因此，以下是我从之前链接的帖子中“摘取”的Ijh建议和代码：

当然希望这能帮助其他人走出困境！ 肖恩
