【问题描述】：
每个商店都有自己的数据库（我同意这是不好的做法），我需要从所有满足特定条件的单个数据库中获取数据。到目前为止，我已经想出了这个，但我得到了一个错误
消息 102，第 15 级，状态 1，第 81 行
')' 附近的语法不正确。
我认为这将显示我需要实现的目标，动态 SQL 是执行此任务的最佳方式吗？如果是这样，我该怎么做才能消除我的错误。如果没有，更高级的 SQL 用户可以提供什么想法/想法/重写。

【问题讨论】：
-
你有额外的 ) 在最后。它应该是
+ @dbname + ')')也让你的@dbname nvarchar。 -
@artm - 很好。你会推荐这是一个使用内联 sql 的案例吗？
