对象绑定如何取消MSSQL数据库对象绑定（mssql数据库怎么取消）

Object binding allows two components of a relational database system, such as tables or stored procedures, to be bound together. It is a powerful system that can help streamline the development process and improve user experience. However, when it is no longer needed, it might be necessary to remove the binding. In this article, we will discuss how to unbind a MSSQL database object.

The first step to unbind an object is to find the object that needs to be unbound. This can be done using the built-in system objects in MSSQL. open the object explorer, right-click the table that needs to be unbound, and select “delete”. This will delete the object from the database.

Once the object has been deleted, the remaining steps involve using T-SQL and the “sp_unbindef” system stored procedure. This stored procedure allows the user to unbind object references from the user database.

First, a “user-defined function” needs to be created that includes the table or stored procedure name as an argument. The function should then reference the table or stored procedure name and then use the “sp_unbindef” stored procedure to unbind the object:

CREATE FUNCTION UnbindObject(@object varchar(50))

BEGIN

EXEC sp_unbindef @object

END

Next, the user-defined function needs to be called with the name of the object to be unbound:

exec UnbindObject ‘Table_Name’

Finally, the unbound object can be removed from the database using the “drop” command:

DROP Table_Name

In this article, we discussed how to unbind a MSSQL database object. Using the built-in system objects and T-SQL it is quite simple to unbind an object and remove it from the database. As always, it is important to make sure that the correct object is unbound and to ensure that no data is lost before the unbind process is complete.
