* `compact_arrays`: `true` to use array-of-arrays structure for the result set,

rather than the default array-of-hashes structure.

### `db:set_timeout(time)`
|

|

Sets the timeout (in ms) protection for subsequent operations,

### `db:close() -> 1 | nil,err`
|

Closes the current mysql connection and returns the status.
