How do I execute clob in execute immediate

I have a table with one row and clob as column (whose size is 5239). This column contains a table script extracted with the help of dbms_metadata.get_ddl. Along with table ddl it also extracts the primary key constraint and unique index script.

When I try to execute the script in my plsql block with execute immediate, it throws the following error:

ora-00922: missing or invalid option

Can somebody help me with what might be going wrong?

DECLARE lr_ddl CLOB;

BEGIN
    SELECT TEXT INTO lr_ddl FROM DUMMY_1;
    EXECUTE IMMEDIATE lr_nvm_ddl;

    EXCEPTION WHEN OTHERS 
              THEN raise_application_error(-20001, chr(10)||' Failed ' || SQLERRM);
END;

Below is the script that I have in clob and I am trying to execute with execute immediate in my anonymous block.

Solution

You could execute those commands one by one in a LOOP. Something like in the code here. I just printed the commands, but you could execute them:

    SET SERVEROUTPUT ON
    DECLARE
        mySQL  VarChar2(8000);
        mySQLexecute  VarChar2(8000);
    BEGIN
       SELECT TEXT INTO mySQL FROM DUMMY_1;
       --
        WHILE InStr(mySQL, ';') > 0 LOOP
          mySQLexecute := SubStr(mySQL, 1, INSTR(mySQL, ';'));
-- OR mySQLexecute := SubStr(mySQL, 1, INSTR(mySQL, ';')-1);  if you want a command without semicolon (;)
          DBMS_OUTPUT.PUT_LINE(mySQLexecute);
          --EXECUTE IMMEDIATE mySQLexecute;
          mySQL := SubStr(mySQL, INSTR(mySQL, ';') + 1);
        END LOOP;
    EXCEPTION WHEN OTHERS THEN
      raise_application_error (-20001, chr(10)||' Failed ' || SQLERRM);
    END;
