mySQL Variables in SELECT

mysql, sql, t-sql

Solution

Don't forget the `:=` for user variable , @threadIDvar`:=`threads.id

Problem

Is it possible to have a query such as the following: ``` SELECT @threadIDvar = `threads`.`id` AS `threadID`, (SELECT `posts`.`timeDate` FROM `posts` WHERE `posts`.`threadID` = @threadIDvar) AS `postDate` FROM `threads` INNER JOIN `posts` ON `posts`.`threadID` = `threads`.`id` WHERE `threads`.`boardID` = 1 ``` I have tried it but I get @threadID returned as NULL and consequently postDate also as NULL. How do I get the variable @threadIDvar to be filled with the returned threadID?
