Live demos

Each demo runs the real parser on SQL you paste in — no install, no signup.

• Parse SQL to get table column Extract every table and column a statement touches
• Parse SQL to rename table column Refactor identifiers safely across a statement
• Data lineage analysis / dataflow Column-level lineage from raw SQL
• Column impact analysis What breaks downstream if this column changes
• Detect and prevent SQL injection Flag injection patterns before execution
• Convert SQL to XML The full parse tree as an XML document
• Rewrite proprietary joins to ANSI SQL Oracle / SQL Server join syntax → ANSI-compliant joins

Prefer to evaluate against your own hard cases in private? Send a SQL sample and Gudu reviews it with you.
