Install guideFormat and beautify SQL queries for various dialects.
Format SQL statements for readability, review, and troubleshooting before sharing queries in code reviews or incidents, with a workflow focused on dialect awareness, maintainability, and safe operational handoff.
It restructures SQL with normalized indentation, line breaks, and keyword layout.
It also supports minify behavior for compact storage or transport scenarios.
It improves query review clarity by exposing join boundaries, filter conditions, and ordering logic in a predictable visual structure.
It helps teams align SQL style across repositories, making migrations, dashboards, and incident runbooks easier to parse under pressure.
Raw SQL
select u.id,u.name from users u join teams t on t.id=u.team_id where u.active=1 order by u.created_at desc;
Multiline SQL
with active as (...) select * from active;
Aggregation query
select team_id,count(*) c from users where active=1 group by team_id having count(*)>5;
Formatted SQL
SELECT u.id, u.name FROM users u JOIN teams t ON t.id = u.team_id WHERE u.active = 1 ORDER BY u.created_at DESC;
Minified SQL
SELECT u.id,u.name FROM users u JOIN teams t ON t.id=u.team_id WHERE u.active=1;
Review note
After formatting, verify predicates, aliases, and GROUP BY semantics still match business intent.
Dialect-specific syntax appears invalid
Confirm dialect and reserved keyword behavior for your DB.
Hidden control characters from copy/paste
Re-paste as plain text before formatting.
Assuming formatter optimizes query plan
Formatting improves readability, not execution performance.
Overlooking alias ambiguity
Use explicit aliases and qualify columns to avoid confusion in multi-join statements.
Applying one style to incompatible dialects
Validate output using the target engine parser before production use.
SQL Formatter should be treated as a repeatable validation step before merge, release, and handoff.
Will formatting change SQL semantics?
It should preserve query meaning while changing whitespace and layout.
Can I use it for migration scripts?
Yes. It is useful for reviewing migration readability before execution.
Does it validate database permissions?
No. It only reformats text and does not run queries.
Can formatting help performance tuning directly?
Not directly, but clearer query structure makes it easier to reason about indexes and execution plans.
How should teams enforce SQL style consistency?
Adopt shared formatting conventions in reviews and automate checks where possible.
