I have build a follow system but that system displays all members who are even temporarily deactivated, for disabling deactivated members from showing in areas such as followers or following I have added a column 'closed' in members table which is initially set to no
and when a member wants to temporarily deactivate his profile this no is updated to yes. Now my idea is to join the select
statement which selects members followed or following from follow
table with members with the column closed
set to no
in members
table so my system displays only activated members.
My select statement is:
SELECT * FROM follow WHERE uid=:memberid
I tried but get syntax error for this:
SELECT * FROM follow INNER JOIN members on members.memberid=follow.uid WHERE uid=:memberidid WHERE closed=no
而不是使用WHERE
两次,你可以使用AND
对“第二” WHERE
-clause。
SELECT * FROM `follow` INNER JOIN `members` ON `members`.`memberid` = `follow`.`uid` WHERE `uid` = :memberidid AND `closed` = "no"
SELECT * FROM
follow INNER JOIN members
on members.memberid=follow.uid
WHERE follow.uid=follow.memberid
AND members.closed='no'
