Question

如何修复无效的对象表名称？

SELECT Proc_Code
FROM ClinicProcedures
WHERE Proc_Code NOT IN (SELECT Proc_Code FROM Patient)

Answer 1

Make sure you are in the correct database that has those objects. Most likely, you are in the master database.

Lookup the "USE {database}" command in the documentation. Alternatively, you can use the full naming convention of objects, and execute in any database:

SELECT Proc_Code FROM MyDatabase.myschema.ClinicProcedures WHERE Proc_Code NOT IN (SELECT Proc_Code FROM MyDatabase.myschema.Patient);

Answer 2

此错误通常是由于数据库上下文不匹配而发生的。用户打开SSMS时，不会注意到默认数据库设置为master。您只需要将数据库上下文更改为当前对象的数据库即可。
