Question

I have two tables, each with an “id” field. Here are the two tables:

news    : id, authorid, datetime, body
authors : id, name

I have this select query:

SELECT * FROM news, authors WHERE (news.authorid = authors.id) ORDER BY news.datetime DESC;

Then, in PHP, I want to use id of the table news. I have this code:

while ($row = mysql_fetch_array($result)) 
{
    // I want to take news.id, but it gives an error:
    echo $row["news.id"]; // error: "Undefined index: news.id"

    // And when I write only "id", it takes it of authors.
    echo $row["id"]; // this id is authors.id, but I want news.id
}

Answer 1

Give them aliases

SELECT news.id AS news_id FROM news, authors WHERE (news.author = authors.id) ORDER BY news.datetime DESC;

Or

SELECT *, news.id AS news_id FROM news, authors WHERE (news.author = authors.id) ORDER BY news.datetime DESC;
