SQL Minifier

SQL minification removes unnecessary whitespace, line breaks, and comments from your SQL queries to make them more compact. For example, this formatted query:

SELECT
    id,
    name,
    category
FROM
    tools
WHERE
    type = 'spreadsheet'
ORDER BY
    popularity DESC;

becomes:

SELECT id, name, category FROM tools WHERE type='spreadsheet' ORDER BY popularity DESC;

Common reasons to minify SQL include:

• Logging: Compact queries take less space in log files
• URLs/APIs: Shorter queries for query parameters or API calls
• Storage: Reduced size when storing queries in databases
• Comparison: Easier to compare queries when whitespace is normalized

Yes. Both single-line comments (-- comment) and multi-line comments (/* comment */) are removed during minification. Make sure to save any important comments separately before minifying.

No. Minification only removes whitespace and comments. Your actual query logic: table names, column names, conditions, values, and operations remain exactly the same. The minified query will execute identically to the original.

The minifier will still attempt to minify your SQL even if it contains syntax errors. However, you'll see a warning message indicating that your query was minified but may contain syntax issues. This helps you get a compact version while being aware that corrections may be needed.
