Smart DDL with Conditional Create and Drop
'Skip the pain of pre-checks when creating or dropping objects.'
"SQL> -- Only create table if it doesn't already exist
SQL> CREATE TABLE IF NOT EXISTS dept (
2 dept_id NUMBER,
3 dept_name VARCHAR2(100)
4* );
Table DEPT created.
SQL>
SQL> -- Safely drop table if it exists
SQL> DROP TABLE IF EXISTS dept;
Table DEPT dropped."
'Use Case: Safer and cleaner DDL in deployment scripts.'
