在一个php页面中使用两个表(mysql) [英] Use two tables in one php page (mysql)

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.
