Que fait SQL Formatter ?
SQL Formatter permet de formater et valider des données dans le navigateur et présente clairement le résultat et ses limites. Fonctions vérifiées : Multiple SQL dialects, Keyword casing, Two-space formatting, SQL minification.
Format for review; minify for compact transport
Formatted SQL emphasizes clauses and indentation for human review. Compact SQL is harder to audit. This mode preserves comments, optimizer hints, and meaningful newlines; it may remain on multiple lines.
Comment l’utiliser ?
- Choose Format SQL or Minify SQL and select the database dialect that matches the query.
- Paste SQL into Input and select Convert.
- Review the output against the target database; formatting does not execute or validate the query.
Exemple réel d’entrée et de sortie
Minify a simple query
Entrée
SELECT id, name
FROM users
WHERE active = true;Sortie
SELECT id, name FROM users WHERE active = true;Minify collapses whitespace outside quoted values, identifiers, and comments. It preserves comments and hints and does not verify query semantics.
Erreurs fréquentes et corrections
| Symptôme | Cause probable | Correction |
|---|---|---|
| Formatting fails near a vendor-specific clause. | The selected dialect does not recognize syntax used by the query. | Choose the matching MySQL, PostgreSQL, SQLite, SQL Server, BigQuery, or Standard SQL dialect. |
| Formatted SQL still fails in the database. | A formatter does not know the schema, permissions, parameter values, or runtime types. | Run the query through the database parser or a safe test environment after formatting. |
