[PHP-DB] Selecting data from multiple tables | [PHP-DB] If in a query
Hi


You did not mention your DB , but following syntax should get you on your
way

select tbl1.user_id
,	tbl1.username
,	tbl2.age
,	tbl3.town
,	tbl3.country
from 	tbl1
,	tbl2
,	tbl3
where tbl1.user_id=tbl2.user_id
and	tbl1.user_id=tbl2.user_id
and 	tbl2.user_id=tbl3.user_id (not neccessary but sometimes better
performance)
and 	tbl2.age=30
and 	tbl3.country='UNITED KINGDOM'

Subject: [PHP-DB] Selecting data from multiple tables


I have three tables as shown below:

tbl1
---------------
user_id
username
password
..............
..............

tbl2
--------------
user_id
age (date)


tbl3
-----------
user_id
town
country

How can i construct sql query for example to select data from all three
tables where age is 30 and country is United Kingdom?

Many Thanks in Advance.
