A free online SQL parser backed by the real GSP Java engine — not a mock response. Paste a statement or script and inspect syntax, objects, and a bounded AST across 39 dialects. Run an on-demand column-lineage preview for every Java-supported dialect, with explicit completeness diagnostics. Static routines and fully materialized dynamic SQL are supported; incomplete SQL-string concatenation is explicitly rejected rather than shown as a misleading graph.
GSP parses the text for this response. It does not execute SQL or connect to a database.
Demo-only endpoint · rate-limited · no production SLA
Run the parser to inspect statement types, syntax errors, referenced objects, and AST nodes.
A bounded token-span parse-tree preview. Node labels and source coordinates come from GSP; SQL fragments are intentionally omitted.
The preview reached its public-demo node limit. Run the SDK locally for the complete tree.
Trace column-level relationships across all 39 Java-supported dialects. No catalog is connected; incomplete SQL-string concatenation is not analyzed.
Relationships returned by the bounded SQL-only analysis.
The public demo is deliberately bounded. Add the trial SDK to your own project for complete parser APIs and offline evaluation, or request an unrestricted evaluation build for real scripts.
