# SQL Dialect Bridge

Translate SQL between MySQL, PostgreSQL, SQLite, BigQuery, Snowflake, and Redshift — DDL, DML, functions and types, with UNSUPPORTED warnings

## Overview

Rule-based SQL dialect translator. Covers auto-increment keys (AUTO_INCREMENT↔SERIAL↔IDENTITY), row limits (LIMIT↔FETCH FIRST), string aggregation (GROUP_CONCAT↔STRING_AGG↔LISTAGG), date functions (DATEDIFF↔DATE_DIFF↔EXTRACT), type mapping (TEXT↔VARCHAR↔STRING) and per-dialect functions. Constructs that cannot be translated mechanically are flagged UNSUPPORTED for manual review. Pure local, deterministic, no AI.

## Inputs

- **Source SQL** (textarea): Paste SQL from the source dialect... SELECT GROUP_CONCAT(name SEPARATOR ', ') FROM users LIMIT 10;
- **Source dialect** (select)
- **Target dialect** (select)
- **Preserve formatting** (checkbox)

## When to use

- Convert SQL during a database migration between supported dialects.
- Rewrite dialect-specific functions, types, limits, or auto-increment definitions.
- Review a translated query for constructs that cannot be converted mechanically.

## How it works

- Paste the source SQL into the input field.
- Select the source and target dialect from the supported database options.
- Choose whether to preserve the original formatting.
- Review the translated SQL and any UNSUPPORTED warnings in the HTML result.

## Use cases

- Convert MySQL table definitions and queries to PostgreSQL syntax.
- Adapt PostgreSQL queries for BigQuery while reviewing unsupported expressions.
- Map functions and data types when comparing or migrating supported SQL databases.

## Frequently asked questions

### Which SQL dialects are supported?

The tool supports MySQL, PostgreSQL, SQLite, BigQuery, Snowflake, and Redshift.

### What SQL can it translate?

It translates supported DDL, DML, functions, types, row limits, string aggregation, date expressions, and auto-increment syntax.

### Does it translate every SQL statement automatically?

No. Constructs without a mechanical translation are marked UNSUPPORTED for manual review.

### Can I preserve the source formatting?

Yes. Enable the Preserve formatting option before translating the SQL.

### Does the tool use AI?

No. It uses local, deterministic, rule-based translation.
