connectAndQuery

Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

Begin an async connection and query to a MySQL instance

public static function connectAndQuery(
  Traversable<string, arraykey> $queries,
  string $host,
  int $port,
  string $dbname,
  string $user,
  string $password,
  AsyncMysqlConnectionOptions $conn_opts,
  dict<string> $query_attributes = dict [
],
): Awaitable<(AsyncMysqlConnectResult, Vector<AsyncMysqlQueryResult>)>;

Use this to asynchronously connect and query a MySQL instance.

Normally you would use this to make one query to the MySQL client.

If you want to be able to reuse the connection use connect or connectWithOpts

Parameters​

  • Traversable<string,arraykey> $queries
  • string $host - The hostname to connect to.
  • int $port - The port to connect to.
  • string $dbname - The initial database to use when connecting.
  • string $user - The user to connect as.
  • string $password - The password to connect with.
  • AsyncMysqlConnectionOptions$conn_opts
  • dict<string> $query_attributes = dict [ ] - Query attributes. Empty by default.

Returns​

  • Awaitable<(AsyncMysqlConnectResult,Vector<AsyncMysqlQueryResult>)> - an Awaitable representing the result of your connect and query This is a tuple where the latter contains information about the connection retrieval, and the former has the query results
