You’re talking about calling Toad functionality from a script, and I don’t know about that. But as an alternative, here’s a PL/SQL function you can call from
a SQL script (or a PL/SQL module). Look at the package function DBMS_METADATA.GET_DDL. Pass it an object type (such as ‘CONSTRAINT’), and the object name and owner, and it should give you the exact command that you can later EXECUTE IMMEDIATE to rebuild the
object after you drop it.

Subject: [Toad for Oracle - Discussion Forum] Calling built-in functions in code
Calling built-in functions in code
Thread created by edluver216
Let me first apologize for asking what I am sure is a question that has been covered before in these forums. I have been searching for days for a solution but I’m guessing my ignorance of the
terminology is an obstacle I just can’t overcome. Preface: I am working on a project that requires me to alter the primary key in several tables. As we all know, that also requires me to drop and then recreate any foreign key constraint that references
the primary key before proceeding, and there in lies my dilemma. I know Toad gives me the ability to right click on a restraint and generate the code (“create script”) that will recreate the restraint, what I want to do is call that in my script based on
the name of the primary key which I will pass in through the script. (For example, if my customer table has a primary key of “people” and it is referenced in the address and office table as a foreign key constraint, my script would use the SYS tables to determine
what foreign keys reference “people” and then call the “create script” command on those keys and spool them [maybe] so that I am create them again after the primary key is changed) Is what I’m trying to do possible? If so, what are those built-in commands
called? Is there a more efficient way of doing what I am trying to do? Any help will be appreciated…
