SQL 服务器 SP 错误消息 4145，级别 15，状态 1

SQL Server SP error Msg 4145, Level 15, State 1

当我尝试 运行 对 select and/or 插入的单独查询时，它起作用了。当我把它放在 SP 中并为所有数据库 运行 时，它会出错。

Msg 4145, Level 15, State 1, Line 45 An expression of non-boolean type specified in a context where a condition is expected, near 'Addr'.

EXEC sp_MSforeachdb @command

简短的回答是您的 sql 命令太长了。

此未记录的存储过程 sp_msforeachdb 不接受与 varchar(max) 一样长的 varchar。事实上，在 SQL SERVER 2019 上，如下面的 db -fiddle 所示，它只接受 2000 个字符，这会导致您的部分查询被截断。因此，您的连接表达式不完整，导致错误消息 Msg 4145, Level 15, State 1, Line 45 An expression of non-boolean type specified in a context where a condition is expected, near 'Addr'..

我会推荐一个较短的查询或在一个通常可访问的数据库中使用您的查询创建一个存储过程，然后 运行 从那里执行命令或以不同的方式将您的查询重写为 运行。我还在这个答案的末尾包含了一些建议。

您可以使用我在下面使用的存储过程 sp_helptext 来了解有关您的数据库版本中的定义的更多信息。

证明上述内容的代码和可重现示例fiddle如下所示。
