从 SQL 服务器中的表中删除特定列时，更改存储过程不会引发“无效列名”错误

Question

I have removed a column from a table which is referred in a stored procedure. When I alter that stored procedure, there is no error, but when executing it, an error

Invalid column name

is thrown.

I'm using SSMS 2017

You are looking for functionality called "schema binding". This means that if you cannot change the schema of an object if it is being referenced in a view or stored procedure.

This is handled on the dependent level, rather than on the original object. The place to start is with the documentation on SCHEMABINDING .

In practice, this means the following procedure:

1. Alter the object (ie table).
2. Get a schema binding error.
3. Drop the schemabinding option on all objects that refer to the original object.
4. Modify the original object.
5. Modify the dependent objects.
6. Be sure schema binding is back "on" the dependent objects.

It is a bit cumbersome, but it helps enforce database dependencies.
