如何解决SQL Server SP 错误消息 4145，级别 15，状态 1
当我尝试为选择和/或插入运行单个查询时，它可以工作。当我把它放在 SP 中并为所有 DB 运行它时，它出错了。
Msg 4145,Level 15,State 1,Line 45 非布尔类型的表达式 在预期条件的上下文中指定，靠近“Addr”。
Declare @command varchar(MAX)
Select @command = '

IF DB_NAME() not like ''%_VER''
BEGIN RETURN END

EXEC sp_MSforeachdb @command
解决方法
简短的回应是你的sql命令太长了。
这个未记录的存储过程 sp_msforeachdb 不接受 varchar(max) 一样的 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'.。
我建议使用较短的查询或在通常可访问的数据库中使用您的查询创建存储过程，然后从那里运行命令或重写您的查询以不同方式运行。我还在这个答案的末尾提供了一些建议。
您可以使用我在 sp_helptext 下面使用的存储过程来了解有关您的 db 版本中的定义的更多信息。
证明上述内容的代码和可重现的示例小提琴如下所示。
