Help me with this query

[Davilac]

Hello, I want to get topic's id and topic's subject. I know the table, messages, I know what I need is the subject's of the minimum ID_MSG for every ID_TOPIC, but I don't know how make this.
I only need the SQL syntax, nothing more.

If you didn't understand, I will explain better. I'm writing a little mod, and I need to get all topic's URL and subject, to make a link for them, like a forum.

Thank you

Do you mean this?

MessageIndex.php:411-601 will help you

Too data and too dificult for me  I need something easier, because my script will run using only SSI.php, and most and I have not most variables. I need something easier...

$request = db_query("
SELECT ID_MSG, {$db_prefix}messages.ID_TOPIC, {$db_prefix}messages.ID_BOARD,
{$db_prefix}messages.subject, {$db_prefix}messages.posterName, {$db_prefix}topics.ID_FIRST_MSG
FROM {$db_prefix}messages, {$db_prefix}topics
WHERE ID_MSG=ID_FIRST_MSG
ORDER BY ID_TOPIC ASC ", __FILE__, __LINE__);
