Claude Code SQL Formatting for Column Alignment and Four-Space Indentation

Format SQL statements consistently so columns, parentheses, and continued clauses are easier to review.

Install in Claude Code

Open the project in Claude Code and provide the SQL excerpt to format. The example uses a fictional library table.

Review `.claude/skills/sql-formatting/SKILL.md` and its requirements at the pinned GitHub commit.
Create `.claude/skills/sql-formatting/` in your project and save the reviewed file as `.claude/skills/sql-formatting/SKILL.md`.
Start Claude Code from that project's root, then select `/sql-formatting` in the slash menu.

Example task

Apply Claude Code SQL formatting to this fictional shelf label table definition.

CREATE TABLE shelf_labels(book_code TEXT NOT NULL, floor_number INTEGER NOT NULL);

What to check

Use one line per column in `shelf_labels`, with four-space indentation and column type alignment. Preserve the column types and constraints.

CREATE TABLE shelf_labels
(
    book_code    TEXT    NOT NULL,
    floor_number INTEGER NOT NULL
);
