Something just like this
select
(
case when
( (select t1.name from table_1 as t1)=(select t2.name from table_2 as t2) )
then 'same'
else 'different'
end
);
I want to compare 'name' from table_1 with the 'name' from table_2 and if they are equals it shows in the field "same name" and if not, it shows "not the same".
There's any kind of case
(or anything else) that I can do that?
I will have to do this with multiple fields (name, last name, age, etc...), and I just can't figure this simple query out.
Here's another comparison that i want but now with two columns:
Table A:
ID - NAME - Age
1 rick 12
2 denis 21
3 jane 34
4 john 38
5 jerry 76
6 max 54
Table B:
ID - NAME - Age
1 rick 10
2 jay 21
3 morris 34
4 john 38
5 jerry 79
6 morty 54
Result from comparing each field with the condition that i want:
ID - Name - Age
1 Same Different
2 Different Same
3 Different Same
4 Same Same
5 Same Different
6 Different Same
try this will help
SELECT CASE
WHEN t2.name IS NULL THEN 'not the same'
ELSE 'same name'
END
FROM table_1 t1
LEFT JOIN table_2 t2 ON t1.name = t2.name
So in my case, it was needed to have a relation between tables, so there it goes:
Table 1
create table table1 (
id int auto_increment,
name varchar(40),
age int,
primary key (id)
);
Table 2
create table table2 (
id int auto_increment,
name varchar(40),
age int,
primary key (id),
CONSTRAINT `id` FOREIGN KEY (`id`) REFERENCES `table1` (`id`)
);
Insert some data in both tables...
insert into table1 (name,age) values
('morty',14),
('rick',70),
('beth',35);
insert into table2 (name,age) values
('morty',14),
('rick',50),
('beeth',35);
Query that i wanted:
(select t1.name as t1name,t2.name as t2name,
(case
when t1.name = t2.name then 'same' else 'dif'
end) as resultName, t1.age as age1,t2.age as age2,
(case
when t1.age = t2.age then 'same' else 'dif'
end) as resultAge
from table1 as t1
left join table2 as t2 on t1.id = t2.id
)
order by t1name,t2name;
Result:
t1name t2name resultName age1 age2 resultage
beth beeth dif 35 35 same
morty morty same 14 14 same
rick rick same 70 50 dif
