SQL front-end for the [wasm-dbms](https://crates.io/crates/wasm-dbms) DBMS engine.

This crate parses SQL text, binds it to a `wasm-dbms` schema, and runs it
against a `DbmsContext`. It covers queries (`SELECT` with joins, `DISTINCT`,
aggregates, `GROUP BY`, `HAVING`, `ORDER BY`, `LIMIT`, `OFFSET`), writes
(`INSERT`, `UPDATE`, `DELETE`), and transactions (`BEGIN`, `COMMIT`,
`ROLLBACK`). Tables are still defined with `#[derive(Table)]`: there is no
schema-changing SQL.

## Usage

```toml
[dependencies]
wasm-dbms = "0.9"
wasm-dbms-api = "0.9"
wasm-dbms-memory = "0.9"
wasm-dbms-sql = "0.9"
```

```rust,ignore
use wasm_dbms::prelude::*;
use wasm_dbms_api::prelude::*;
use wasm_dbms_memory::prelude::HeapMemoryProvider;
use wasm_dbms_sql::SqlEngine;

#[derive(Clone, DatabaseSchema)]
#[tables(User = "users")]
pub struct MySchema;

let ctx = DbmsContext::new(HeapMemoryProvider::default());
MySchema::register_tables(&ctx)?;

let engine = SqlEngine::new(MySchema);

engine.execute(
    &ctx,
    None,
    "INSERT INTO users (id, name) VALUES (?, ?)",
    &[Value::from(1u32), Value::from("Alice")],
)?;

let result = engine.execute(
    &ctx,
    None,
    "SELECT name FROM users WHERE id = 1",
    &[],
)?;
```
