Bind Variables & Cursor Sharing
Why one line of coding habit — using bind variables instead of literal values — is the single biggest lever over both query performance and SQL injection safety.
Learning objectives
- Distinguish hard parse from soft parse and explain why the distinction matters for throughput
- Explain what a cursor is and what it tracks for a running SQL statement
- Rewrite a literal-value query as a bind-variable query and explain the performance difference
- Explain how CURSOR_SHARING works as a database-side safety net
- Connect bind variables to SQL injection prevention, not just performance
