View with IF NOT EXISTS

View with IF NOT EXISTS is a SQL statement in the Views category. Creates a view only if it does not already exist. Prevents errors on re-execution. The syntax is CREATE VIEW IF NOT EXISTS view_name AS select_statement;. It returns conditional view creation. A typical example: CREATE VIEW IF NOT EXISTS active_employees AS SELECT * FROM employees WHERE status = 'active'; -- No error if view already exists CREATE OR REPLACE VIEW active_employees AS SELECT id, name, department, salary FROM employees WHERE status = 'active'; -- Replaces existing view with updated definition -- MySQL and SQLite support IF NOT EXISTS for views -- PostgreSQL: use CREATE OR REPLACE VIEW instead A close relative is CREATE VIEW, which creates a virtual table based on a SELECT query. Think of it as a saved query that acts like a table. A close relative is DROP VIEW, which removes a view from the database. Does not affect the underlying tables.
