# Validate > Validate SQL and report diagnostics using syntaqlite. Use when the user wants to check SQL for errors, lint SQL files, or verify correctness against a schema. Use when this capability is needed. - Skill: `tomevault-io/validate-8` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/validate-8` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/validate-8/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Data & Analytics - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/validate-8 --- # Validate SQL Validate SQLite SQL and report diagnostics (errors, warnings) using the syntaqlite CLI. ## Usage ```bash # Validate a file syntaqlite validate query.sql # Validate from stdin echo "SELECT * FORM t" | syntaqlite validate # Validate an inline expression syntaqlite validate -e "SELECT 1 + " # Validate against a schema syntaqlite validate --schema schema.sql query.sql # Validate multiple files via glob syntaqlite validate "**/*.sql" # Validate with multiple schema files syntaqlite validate --schema "migrations/*.sql" --schema extra.sql query.sql ``` ## Options - `-e, --expression ` — Validate an inline SQL expression instead of files - `--schema ` — Schema DDL file to load before validation (repeatable, supports globs) - `--experimental-lang ` — Extract embedded SQL from host language files (`python`, `typescript`) ## Notes - Without `--schema`, validation checks syntax only. With `--schema`, it also checks table/column references. - Exit code is 0 if valid, non-zero if errors are found. - For continuous validation while editing, the LSP server provides real-time diagnostics automatically. --- > Source: [LalitMaganti/syntaqlite](https://github.com/LalitMaganti/syntaqlite) — distributed by [TomeVault](https://tomevault.io).
