Question

我想：

创建一个临时表，其中包含TBTRIGPMMCANC和TBPROPPAY上所有id_payments的列表。

从此列表中将它们从TBPROPPAY移至TBPROPPAYH。

然后从TBPROPPAY删除它们。

这是我的sql我在插入语句中有问题。我想我需要像以前一样的SQL将行移动到临时表中的每个id_payment的tbproppayh但我不知道如何写它

错误是： E_US0AD8 INSERT：目标列数必须等于目标数列出指定子选择中的元素。（Thu Jul 18 09:31:23 2013）

Answer 1

如果您想要临时表，最好使用视图。您可以获得所需的所有详细信息，然后从视图中获取。

请稍后发布代码。

你得到的错误是相当自我解释的。您为目标选择了太多列。

Answer 2

如果表tbproppayh有多个列，则必须在INSERT语句中指定受影响的列：

Insert into tbproppayh (mycolumn)
Select id_payment

另一个建议，在id_payment字段之前放置别名表，否则在修复第一个错误后，你会在ambiguos字段上得到另一个错误。
