Sql 试图解压

我正在尝试取消Pivot我以前创建和透视的表，并获取错误信息：

ORA-00904:：标识符00904无效。00000-“%s:无效标识符”*原因： *操作：第107行第1列出错

这是否与我试图透视的列与行的数据类型不同有关

select 
sales_per_month, 
Product_id, 
Total_amount 
from pivoted_sales 
unpivot((Total_amount) for (Product_id) in( 
100 as '100', <- 107 
101 as '101',
105 as '105', 
106 as '106',
200 as '200'))

选择
每月销售额，
产品标识，
总金额
从数据透视销售
在（
100作为'100'，我认为您需要在
unpivot
列名称中使用
“
而不是
”

select 
sales_per_month, 
Product_id, 
Total_amount 
from pivoted_sales 
unpivot(Total_amount for Product_id in( 
"100",
"101",
"105", 
"106",
"200"))

您希望
“100”作为100
而不是
100作为“100”
