English-to-SQL Bot: Verified In-Memory Execution

Most AI SQL tools hallucinate column names or generate broken JOIN syntax that crashes in production. English-To-SQL creates an isolated in-memory SQLite sandbox, runs the query, verifies the table output, and provides both the query and raw records.

Tested Multi-Table JOIN Example (SQL-LIVE-002)

Below is the verified end-to-end execution of a relational customer orders query:

Schema & English Request

CREATE TABLE customers (id INT, name TEXT);
CREATE TABLE orders (id INT, customer_id INT, amount REAL);

INSERT INTO customers VALUES (1, 'Alice'), (2, 'Bob');
INSERT INTO orders VALUES (101, 1, 120.50), (102, 1, 45.00), (103, 2, 89.00);

Question: Show total spending by each customer, sorted highest first.

Bot Output: Generated & Executed SQL

-- Generated SQL (Verified in SQLite sandbox)
SELECT c.name, SUM(o.amount) AS total_spent
FROM customers c
JOIN orders o ON c.id = o.customer_id
GROUP BY c.id, c.name
ORDER BY total_spent DESC;

Verified Results (2 rows):
| name  | total_spent |
| Alice | 165.50      |
| Bob   | 89.00       |

Status: Success (Executed in 2.1ms)

Dialect Guidance: SQLite vs PostgreSQL vs MySQL

The bot executes on SQLite WASM. When porting queries to larger databases, note these standard dialect differences:

Feature	SQLite (In-Memory Bot)	PostgreSQL	MySQL / MariaDB
String Concatenation	`first \|\| ' ' \|\| last`	`first \|\| ' ' \|\| last` or `CONCAT()`	`CONCAT(first, ' ', last)`
Date Math	`date('now', '-7 days')`	`CURRENT_DATE - INTERVAL '7 days'`	`DATE_SUB(NOW(), INTERVAL 7 DAY)`
Auto-Increment	`INTEGER PRIMARY KEY AUTOINCREMENT`	`SERIAL` or `IDENTITY`	`AUTO_INCREMENT`
JSON Extraction	`json_extract(data, '$.key')`	`data->>'key'`	`data->>'$.key'`

Destructive Query Policy & Security

Destructive Query Guard: If you request a DROP TABLE, TRUNCATE, or unconstrained DELETE, the bot flags a prominent warning and explains production data loss risks before executing in the temporary sandbox.
Stateless Sandbox: Each query session runs in a fresh, isolated database instance. No data persists across turns or requests.
Safe Pagination: Table output is bounded to 50 rows to prevent browser memory exhaustion.

Frequently Asked Questions

Which SQL dialect is used for execution?

The bot executes queries against an in-memory SQLite (WASM) engine. It converts standard ANSI SQL and highlights PostgreSQL or MySQL differences.

Does English-To-SQL connect to my production database?

No. English-To-SQL operates strictly stateless and in-memory. You provide DDL schemas and optional sample rows in the prompt; no network connection to external databases is made.

What happens if a query generates an execution error?

The engine intercepts the SQLite engine error, executes exactly one automated correction retry, and transparently logs the error and fix in the output.
