This Juejin AI tutorial argues that Text2SQL failures usually stem from semantic misalignment rather than invalid SQL, including ambiguous metric definitions, time conventions, oversized schemas, and complex joins. It recommends a six-stage chain spanning schema pruning, semantic-layer injection, few-shot examples, SQL generation, validation, and result explanation, alongside four database safeguards. The article also advocates execution-based evaluation rather than exact SQL-string matching.
