Answer 1

What you are referring to is also known as the INNER JOIN clause in an SQL Statement.

Depending on the relationship you can create an INNER JOIN to potentially connect the two variables that are identical.

SELECT column_name(s)
FROM table1
INNER JOIN table2
ON table1.column_name=table2.column_name;

Answer 2

Try the below query,

SELECT 
gp.giver,gp.acceptor,ui.status 
FROM group as gp JOIN userinfo as ui 
on ui.name = 'zakir' 
AND (gp.giver = 'zakir' or gp.acceptor = 'zakir')

Or try this without join,

SELECT 
gp.giver,gp.acceptor,ui.status 
FROM group as gp, userinfo as ui 
WHERE ui.name = 'zakir' 
AND (gp.giver = 'zakir' or gp.acceptor = 'zakir')

Answer 3

Try this:

SELECT `group`.`giver`, `group`.`acceptor`, `userinfo`.`status`
FROM `group`, `userinfo`
WHERE (`group`.`giver` = 'zakir' OR `group`.`acceptor` = 'zakir')
  AND `userinfo`.`name` = 'zakir'

Answer 4

select g.giver, g.acceptor u.status
from group g, userinfo u
where u.name = 'zakir'
and (g.giver = u.name or g.acceptor = u.name)

It should do a part of the job.

Answer 5

This assumes you want the status for both the giver and the acceptor

May need a little tweaking for mysql syntax

Select giver, g.status, acceptor, a.status 
FROM GROUP 
join userinfo as g on group.giver = g.name
join userinfo as a on group.acceptor = a.name
where (giver = 'zakir' or acceptor = 'zakir')
