zed-sql-tools

SQL extension for Zed with formatting and linting — no external CLI tools required.

Features

Formatter

Automatically formats SQL on save — keywords uppercased, each major clause on its own line.

-- before
select id, name from users where active = 1 order by name

-- after
SELECT id, name
FROM users
WHERE active = 1
ORDER BY name

Supports SELECT, INSERT, UPDATE with WHERE, GROUP BY, ORDER BY. Comments and string literals are preserved as-is.

Linter

Inline diagnostics as you type:

• Syntax errors highlighted immediately
• UPDATE without a WHERE clause — warns before you accidentally update every row
• SELECT without a column list (SELECT FROM users)

Grammar

Uses DerekStride/tree-sitter-sql — the same grammar Zed uses internally for syntax highlighting.
