问题描述
尝试将所有数据检索到一页上...从这样的一个表中检索数据时,我的工作就很好了:
Trying to retrieve all the data onto one page... I've got this working fine when it's retrieving from one table like so:
$data = mysql_query("SELECT * FROM moduleDetails")我尝试做
("SELECT * FROM moduleDetails, qResponses")但这是行不通的,这是我唯一能看到的.
but that doesn't work and is the only thing I can see working.
我听说过使用标识符吗?但是我不太确定如何使用这些...
I've heard about using identifiers? But I'm not quite sure how to use those...
我是PHP的新手,任何提示/示例都很棒.
I am new to PHP, any tips/examples would be great.
推荐答案SELECT md.*, qr.* FROM moduleDetails md LEFT JOIN qResponses qr ON qr.joinColumn = md.joinColumn
无论您用来将它们链接在一起的任何列,都用作joinColumn.
Whatever column you used to link them together, use as the joinColumn.
