You cannot do this. A sql result alwas has the same number of columns in each row. You could have null or "" in the column, though. This could be done via the if(,,)-statement of mysql or by using a union and two selects, one for pub_email=n and the other for the rest.

I am trying to figure out how to return results from a query. What I need to do is to return 4 columns from a database. This is easy: SELECT last_name, first_name, phone, email FROM `mydatabasetable` WHERE `current_member` = "Y" AND `pub_name` = "Y" ORDER BY last_name ASC This works fine, as expected. But, I want to only display the value in `email` if the value in another field, `pub_email` = "Y" So, the resultant output would look like this, for instance, if the value of `pub_email` ="N" for Mr. Wills: Jones John 555-555-5555 johnjo...@nowhere.com Smith Jim 555-222-2222 jimsm...@nothing.com Wills Chill 555-111-1111 Zorro Felicity 555-999-9999 felicityzo...@madeup.com Can't quite figure out how to express this.
