Dear Friends,
I m new on this list, and I m trying to learn more about mysql. After perform a lot of searchs in the Internet, I have no answer to my question and would like to ask your help. I wanna a perform a query that depends of the result from another (query) table inside the same database. On this scenario: I have 02 tables: Table 1 => users Table 2 => sent_emails I wanna select ONLY the users that are NOT inside the table SENT_emails Example: $query1 = SELECT * FROM users WHERE accept_email = 1 The results from query above SHOULD depends of the query Bellow: $query2 = SELECT * FROM sent_emails WHERE email = $email_from_query_above AND messageID NOT LIKE = XXXXXX The results of the first query, should display only the users that are NOT inside the condition of query 2. I read about INNER JOIN LEFT ... but I can´t understand ... Can help me? With Regards, Rafael Ribeiro
