Drops a function-string class.

Syntax

drop function string class function_class

Example 1 – Drops the derived function-string class sqlserver_derived_class and all of its customized function strings:

drop function string class
 sqlserver_derived_class
```
Example 2 – Drops the function-string class sqlserver2_function_class and its function strings:

Use drop function string class to remove a function-string class. function-string classes group all function strings for a database.
Dropping a function-string class also drops all of the associated function strings and removes all references to the class.
A function-string class that is still in use on a database connection cannot be dropped.
You cannot drop any of the three system-provided classes, rs_sqlserver_function_class, rs_default_function_class, or rs_db2_function_class.
You cannot drop any function-string class that is a parent class for a derived class.

drop function string class requires “sa” permission.
