我不知道为什么会发生这种情况，我只是在激活 SQLCMD 模式的情况下检查语法，下面是我的代码。我尝试在创建临时表之前放置一个 drop 语句，但仍然不起作用

if exists (

你可以试试
select * from tempdb.sys.objects where name like '#%' and type = 'U';
这可能会给您一些提示，告诉您哪些内容（如果有的话）可能存在冲突。
这应该更快：
IF OBJECT_ID('tempdb..#tempTable') IS NOT NULL DROP TABLE #tempTable
GO
您可以使用旧语法来检查和删除表。
IF OBJECT_ID('tempdb..#MC_POZ') IS NOT NULL
DROP TABLE #MC_POZ
在较新版本的 SQL Server 中，您可以使用以下命令：
DROP TABLE IF EXISTS #MC_POZ
IF EXISTS当我发现删除的表的名称（带有
DROP TABLE IF EXISTS ...像
#mylongtmptablename#mylongtablename
