SQL Query Inspector

Analyze common SQL structure without executing the query or claiming a full vendor grammar parser.

Inspect SQL without executing it

Use this for fast query orientation: statement types, likely table/CTE references, common clauses, placeholders, comments, strings, and unmatched quote/comment/parenthesis warnings.

WITH paid AS (
  SELECT customer_id, SUM(total) AS spend
  FROM orders
  WHERE status = :status
  GROUP BY customer_id
)
SELECT c.id, c.name, p.spend
FROM customers c
JOIN paid p ON p.customer_id = c.id
WHERE p.spend > 1000
ORDER BY p.spend DESC;

Summary

Normalized fingerprint

Reference	Role	Type

Table extraction is practical lexical analysis. Dynamic SQL, vendor-specific procedural syntax, nested constructs, aliases, functions that return tables, and unusual grammar can require a real dialect parser.

Before running the SQL

The SQL layer keeps transformation, generation, and inspection in the browser. Existing /SQL engines remain intact while the new inspector adds statement, table/CTE, placeholder, clause, and bounded structural-warning context.

Parser and execution boundary

WebToolArc does not connect to a database or execute these statements. The shared scanner handles common lexical structures, quoted strings/identifiers, comments, parameters, and practical references, but it is not a vendor-complete grammar, schema validator, optimizer, lineage engine, or security review. Use a real database/parser when those guarantees matter.
