# rawExecute

Executes a query and returns the **raw PostgreSQL result** without any response transformation. This is the lowest-level query method available.

***

## Signature

```lua
-- Callback
PG.rawExecute(query, parameters?, callback)

-- Sync
local result = PG.rawExecute.await(query, parameters?)
```

### Parameters

| Name         | Type                      | Description                              |
| ------------ | ------------------------- | ---------------------------------------- |
| `query`      | `string`                  | Any valid SQL statement.                 |
| `parameters` | `table?`                  | Array or key-value table of bind values. |
| `callback`   | `function(result: table)` | Called with the raw result object.       |

### Returns

The raw result object from `node-postgres` (`QueryResult`), which includes:

| Field      | Type      | Description                               |
| ---------- | --------- | ----------------------------------------- |
| `rows`     | `table[]` | Array of row objects                      |
| `rowCount` | `number`  | Number of rows returned or affected       |
| `command`  | `string`  | SQL command tag (e.g. `SELECT`, `INSERT`) |
| `fields`   | `table[]` | Column metadata                           |

## When to Use `rawExecute`

Prefer the typed methods (`PG.query`, `PG.single`, etc.) in most situations. Use `PG.rawExecute` when:

* You need access to the `rowCount` on a `SELECT` statement.
* You need column metadata (`fields`).
* You are building a generic query wrapper or ORM layer.
* You want to execute DDL statements (`CREATE TABLE`, `ALTER TABLE`) and inspect the result.

***

## Examples

**DDL execution:**

```lua
PG.rawExecute.await([[
    CREATE TABLE IF NOT EXISTS my_table (
        id SERIAL PRIMARY KEY,
        name TEXT NOT NULL
    )
]])
```

**Inspecting the command tag:**

```lua
local result = PG.rawExecute.await('DELETE FROM sessions WHERE expires_at < NOW()')
print('Deleted ' .. result.rowCount .. ' expired sessions.')
```

***

## Notes

* `PG.prepare` is `PG.rawExecute` with the `prepared` flag enabled (cached query plan).
* No response parsing is applied: `INSERT` does not automatically add `RETURNING *`, and the result is not filtered to rows/counts.
