Encontrou um artigo intitulado "MYSQL WITH NOLOCK"
https:/ /web.archive.org/web/20100814144042/http://sqldba.org/articles/22-mysql-with-nolock.aspx
no MS SQL Server você faria o seguinte:
SELECT * FROM TABLE_NAME WITH (nolock)
e o equivalente MYSQL é
SET SESSION TRANSACTION ISOLATION LEVEL READ UNCOMMITTED ;
SELECT * FROM TABLE_NAME ;
SET SESSION TRANSACTION ISOLATION LEVEL REPEATABLE READ ;
EDITAR
Michael Mior sugeriu o seguinte (dos comentários)
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED ;
SELECT * FROM TABLE_NAME ;
COMMIT ;
