AI SQL Generator for BigQuery
LIVE CONNECTORAI2SQL writes GoogleSQL (Standard SQL) for BigQuery: UNNEST for arrays, STRUCT field access, backtick-quoted project.dataset.table names and partition filters that keep costs down.
What AI2SQL handles for BigQuery
- ✓ Arrays are first-class: UNNEST + CROSS JOIN patterns
- ✓ Table names need backticks: `project.dataset.table`
- ✓ Always filter on partition columns to control scan costs
Generate, explain, optimize and fix — all four tools are dialect-aware, so BigQuery output uses BigQuery syntax rather than generic SQL.
