Hi,
Hi Andy,
the reason I can't use this because fields (columns) in select
statement (p.first_name, p.last_name,...) are actually dynamically
created. In my project different client will select different fields
to be shown. 99% will select first_name, and last_name, but some don't
care about date_registered, some will need more org data...
actually, it will be more this way:
SELECT {$selected_fields} FROM people p, organization o. addresses a
WHERE ...
where
$selected_fields = "p.first_name, p.last_name, o.org_name"
or
$selected_fields = "p.first_name, p.last_name, o.org_name, a.address,
a.city, a.state, a.zip"
or
$selected_fields = "o.org_name, a.address, a.city, a.state, a.zip"
So just tag "AS table_field_name" to each field when you're building
your list of $selected_fields - e.g.
$selected_fields = "p.first_name AS person_first_name, p.last_name AS
person_last_name, o.org_name AS organization_org_name"
You don't have to use the full table name either - for example in the
following statement, you would then access the data using
$result['p']['first_name'];
$selected_fields = "p.first_name AS p_first_name, p.last_name AS
p_last_name, o.org_name AS o_org_name"
This approach is actually easier if you're creating the query
dynamically, because you don't have to manually type a load of "AS xxx"
statements after every field.
I've recently done something similar in one of my applications to wrap
date/time fields in either FROM_UNIXTIME() or UNIX_TIMESTAMP() functions.
