AsyncMysqlException::getResult
Returns the underlying AsyncMysqlErrorResult
associated with the current
exception
public function getResult(): AsyncMysqlErrorResult;
Returns
AsyncMysqlErrorResult
- TheAsyncMysqlErrorResult
that underlies the current exception.
Examples
The following example shows how to use AsyncMysqlException::getResult
to get the AsyncMysqlErrorResult
object associated with this exception. Particularly, we call elapsedMicros()
on that object.
use \Hack\UserDocumentation\API\Examples\AsyncMysql\ConnectionInfo as CI;
async function connect(
\AsyncMysqlConnectionPool $pool,
): Awaitable<\AsyncMysqlConnection> {
return await $pool->connect(
CI::$host,
CI::$port,
CI::$db,
CI::$user,
"thisIsNotThePassword",
);
}
async function simple_query(): Awaitable<?string> {
$pool = new \AsyncMysqlConnectionPool(darray[]);
$conn = null;
$ret = null;
try {
$conn = await connect($pool);
$result = await $conn->query(
'SELECT name FROM test_table WHERE userID = 1',
);
$conn->close();
return $result->vectorRows()[0][0];
} catch (\AsyncMysqlConnectException $ex) { // implicitly constructed
$ret = "Connection Exception";
\var_dump($ex->getResult()->elapsedMicros());
} catch (\AsyncMysqlQueryException $ex) { // implicitly constructed
$ret = "Query Exception";
} catch (\AsyncMysqlException $ex) {
$ret = null;
} finally {
if ($conn) {
$conn->close();
}
}
return $ret;
}
