SQLazy: Compiler-first approach to trustworthy AI SQL
The article describes a growing trust crisis around AI-generated SQL—research and surveys show model hallucinations and low developer trust—and introduces SQLazy, a tool that captures step-by-step natural-language logic and uses a deterministic compiler to produce auditable, production-ready SQL. SQLazy's workflow lets humans validate each logical step (rather than reviewing complex generated SQL), supports multiple SQL dialects (MySQL, PostgreSQL, Oracle; Snowflake and BigQuery planned), and emphasizes auditability, maintainability, and portability for complex analytical queries. The project is free to use via sqlazy.com and has a GitHub repository at SPLWare/SQLazy. The article cites benchmarks (dbt 2026 Text2SQL accuracy 64.5%) and developer sentiment (2025 Stack Overflow survey) to motivate the approach.
Addresses AI hallucination and auditability in data pipelines; introduces a tooling pattern (stepwise logic + deterministic compiler) that can improve data governance, maintainability, and cross-dialect portability for analytical SQL—useful for data teams across AdTech/MarTech but not a platform-level policy change.

Key Takeaways & Evidence Grounding
- According to dbt’s 2026 benchmark, advanced LLMs achieved 64.5% accuracy on Text2SQL tasks.
- A 2025 Stack Overflow survey found only 2.7% of professional developers place a high level of trust in AI tools; 42% of submitted code is AI-generated and only 48% is reviewed by humans.
- SQLazy is a tool that captures step-by-step logic (natural language or assistant-generated) and uses a deterministic compiler to generate executable SQL.
- SQLazy’s compiler currently supports MySQL, PostgreSQL and Oracle; Snowflake and BigQuery support are listed as coming soon.
- SQLazy is available online (sqlazy.com) and has a project repository at github.com/SPLWare/SQLazy; desktop and web versions are free but the tool is not open-source.

Five Checks to Validate AI-Generated SQL
This technical guide explains five quick checks to verify results produced by AI-generated SQL queries. It warns that a running query only proves syntactic correctness and outlines practical tests: (1) compare row counts before and after joins to detect fan-out, (2) watch for NULLs breaking NOT IN filters (use NOT EXISTS), (3) ensure filters sit in WHERE vs HAVING appropriately, (4) confirm the denominator used by averages or percentages, and (5) ask the AI to read the query back clause-by-clause. The author cites the BIRD benchmark (Li et al., 2023) showing large gaps between model and human execution accuracy and provides examples and remediation patterns to avoid incorrect analytics numbers.
Survey: AI-Generated Code Fails Real-World Audit
A Dev.to analysis (published 2026-04-26) synthesizes Sonar’s State of Code Developer Survey and industry datasets to show widespread distrust and operational risk from AI-generated code. Sonar surveyed 1,100 developers and found 96% do not fully trust functional accuracy of AI-generated code and only 48% always verify it before committing. Sonar reports 88% of developers see negative downstream impacts from AI-generated code (53% cite code that “looks correct but isn't reliable”). Combined with GitHub Octoverse 2026 data that 46% of new code is AI-generated and JetBrains findings on daily AI tool usage, the author coins “vibe coding” for the practice of shipping LLM output without robust verification. The piece identifies four common omissions in generated code—error handling, idempotency, retries, and observability—offers example rewrites, and proposes a prompt template to address these production failure modes.
Build an AI Agent That Talks to Your SQL Database
A Spanish-language developer tutorial demonstrates how to build a Text-to-SQL AI agent using Hugging Face's smolagents. The author implements a CodeAgent that writes and executes Python code to run SQL queries via a single @tool-decorated sql_engine function, using an in-memory SQLite demo with receipts and waiters tables. The article explains why an agentic, iterative approach (think-act-observe loop) is more robust than one-shot LLM-to-SQL prompts, shows concrete code examples (including model_ids for meta-llama and Qwen models), and outlines production security controls: read-only access, least-privilege roles, curated views, query limits/timeouts, and full logging/audit trails. The full demo repository and a short demo video are linked in the post.
