SQL Minifier
Compress and minify SQL queries by removing comments, redundant spaces, and newlines into an optimized single-line string.
Quick Answer & Understanding Your Result
An SQL Minifier compresses complex, multi-line SQL queries into a compact single-line string by stripping SQL comments (`--` and `/* */`), extra whitespace, and newlines.
Core SQL Minification Features
- Comment Stripping: Removes single-line comments (
-- comment) and block comments (/* ... */). - Whitespace Collapse: Collapses consecutive spaces while strictly protecting string literals inside single quotes (
'John Doe'). - Single-Line SQL Inlining: Formats queries for embedding inside application code strings (Node.js, Go, Python, Java).
Development Applications
- Inlining SQL in Codebases: Embedding clean single-line queries in ORM queries or database migration scripts.
- Log Size Optimization: Minimizing query string payload size in application performance logs.

Formula & Calculation Logic
Technical Specification & ASTSQL lexical minification:
- Scans SQL token stream, strips non-essential whitespace outside quoted literals, and removes comments.
