Oracle SQL provides the EXECUTE IMMEDIATE command along with BULK COLLECT to dynamically execute SQL statements and fetch multiple rows into PL/SQL collections.
The EXECUTE IMMEDIATE command is used when the SQL statement cannot be determined until runtime, while BULK COLLECT is used to efficiently retrieve multiple rows into collections in a single operation.
Examples provided include fetching multiple rows into a collection, fetching multiple columns into a collection of records, and using bind variables for security and performance.
Using bind variables is recommended to prevent SQL injection and optimize performance.
