Question : SQL syntax for MySql query
Hi,
I am running MySql 5.0.67. I have two tables. Table one contains the details of participants who took part in an event last year. Table two contains participants that will take part in similar event this year. Some of the participants in Table two, may be in Table one. I am after a query that shows me the email addresses from Table two that are not in Table one. Any help would be greatly appreciated.
Thank you.
