Quando tento executar a consulta dentro do bigquery:
SELECT * FROM EXTERNAL_QUERY
("projects/curso-big-query-380423/locations/southamerica-east1/connections/Banco-Bitbyte",
"SELECT * FROM curso WHERE periodo_id = ‘2015.1’;");sempre é retornado o erro:
Invalid table-valued function EXTERNAL_QUERY Failed to connect to MySQL database. Error: MysqlErrorCode(2013): Lost connection to MySQL server during query
