Can SAS code be used to execute a macro written within a database column?

edit

No, SAS code cannot be used to execute a macro written within a database column directly. Macros are typically executed within a SAS program or within another macro, and cannot be executed directly from a database column. However, if the database column contains SAS code that defines and calls the macro, then that code can be extracted from the database and executed within a SAS program or macro.
