Was macht SQL Formatter?
SQL Formatter hilft dabei, Daten zu formatieren und zu prüfen. Die Verarbeitung erfolgt im Browser und Grenzen werden klar beschrieben. Geprüfte Funktionen: 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.
Wie wird es verwendet?
- 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.
Echtes Ein- und Ausgabebeispiel
Minify a simple query
Eingabe
SELECT id, name
FROM users
WHERE active = true;Ausgabe
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.
Häufige Fehler und Korrekturen
| Symptom | Wahrscheinliche Ursache | Korrektur |
|---|---|---|
| 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. |
