Frequently Asked Questions
Does formatting change query behaviour?
No — whitespace and capitalisation changes only. The database executes formatted and minified SQL identically.
SQL keywords uppercase or lowercase?
Convention is UPPERCASE for keywords (SELECT, FROM, WHERE). Consistent capitalisation distinguishes keywords from table/column names visually.
SQL vs NoSQL?
SQL uses relational tables with defined schemas. NoSQL (MongoDB, Redis) uses flexible document or key-value structures. SQL for structured relational data; NoSQL for flexible or high-scale unstructured data.
Does it handle stored procedures?
Yes — stored procedures, functions, triggers, DDL statements (CREATE TABLE, ALTER TABLE) are all formatted.
What is query optimisation?
Writing SQL the database can execute efficiently. Key tips: use indexes on WHERE/JOIN columns, avoid SELECT *, use EXPLAIN to analyse execution plans.
