Question

Table 1 has columns : entry_id user_id …
Table 2 has columns : entry_id user_id …

the user_id entry is not always the same so I would like to extract both of them so I can later on compare them in my script

SELECT * FROM 
table1 as t1
INNER JOIN table2 as t2 on t1.entry_id=t2.entry_id
WHERE t1.user_id='%s'

I would like to extract t1.user_id and t2.user_id …the problem is the result array has only user_id

thank you

Use AS keyword:

SELECT
  t1.user_id as t1_user_id
  ,t2.user_id as t2_user_id
FROM table1 as t1
INNER JOIN table2 as t2
  ON t1.entry_id=t2.entry_id
WHERE t1.user_id='%s'
