given the query:
SELECT * FROM customers
left join addresses
on customer.cusid=addresses.cusid
The mysql monitor returns all fields from both tables, including
repeating the field matching the on condition (cusid).
mysql_fetch_array() does not return the matching field from the joined
table.
If I use the using() conditional I get the same non repeated result, in
both mysql monitor and mysql_fetch_array().
Is it safe rely on this non repeating property of the
mysql_fetch_array() function?
I'm not sure it really makes a difference since data assignment would be
in the form of DataFromField= $row["cusid"], but I have learned from
experience that thinking something will never make any difference is risky.
