  • how to import the attributes from one table to another in mysql

    - by user225269
    Is it possible to import the attributes of one table, then I put it into another table using a query in mysql? For example I have table1 with attributes lname, fname, mname And I want to put those attributes into table2. Is there any query that could do that? I'm imagining that the table2 has one attribute that could later be dropped so that it will be the same as table1.

  • mysql left join queries

    - by Mike79
    I have a question about the snippet below. I'm wondering, if the first query doesn't bring any results, would I still get the results for the second query? select * from ( -- first query ) as query1 left join ( -- second query ) as query2 on query1.id=query2.id left join ( -- third query ) as query3 on query1.id=query3.id; Update: what I need is a full join, however, MySQL does not support it, what would be a good way to emulate this?
