动态SQL无法按预期工作

Question

我正在尝试动态找不到任何Parentsku产品，但是我无法调试该错误。 我正在尝试将结果插入到全局临时表中，但无法正常工作

以下是我收到的错误消息：

"Incorrect syntax near the keyword 'as'.

An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name.
