Question

I am struggling with a MYSQL query – I have 2 tables :

Table 1 (info) containing UID, first_name, last_name.
Table 2 (card) containing UID, pic .

What I am trying to do is get all results into an array:

WHERE UID IN '$ids' AND LEFT(last_name,1) = '$letter' ORDER BY last_name, first_name ASC

I figured an INNER JOIN so my current code is:

("SELECT UID, first_name, last_name, pic FROM 
    (SELECT info.first_name,info.last_name,card.pic FROM info 
     INNER JOIN card ON info.UID=card.UID)
  WHERE LEFT(last_name,1) = '$letter' ORDER BY last_name, first_name ASC")

This is producing the following error though:

‘Every derived table must have it’s own alias’.

Am I going about this the right way with inner join, and how do I give the derived table an alias? Thanks in advance!

Answer 1

select b.UID, g.first_name, g.last_name, b.pic
from user_data.general_info g
inner join user_data.Bcards b on g.UID = b.UID
where LEFT(g.last_name, 1) = '$letter'
order by g.last_name, g.first_name asc
