SQL - Remove Duplicate Results

问题

I have a table that looks like this:

name     | surname<br>
John     |  John<br>
Jessica  |  Madson<br>

I have a query like this:

SELECT * FROM table WHERE name LIKE '%j%' OR surname LIKE '%j%'

What I get:

John John
John John
Jessica Madson

What I want:

John John
Jessica Madson

How can I get rid of the duplicate results?

回答1:

Use DISTINCT:

SELECT DISTINCT name, surname
FROM yourtable
WHERE name LIKE '%j%' OR surname LIKE '%j%'

回答2:

Try:

SELECT DISTINCT name, surname FROM table WHERE name LIKE '%j%' OR surname LIKE '%j%'

回答3:

You could also use group by

SELECT name, surname
FROM yourtable
WHERE name LIKE '%j%' OR surname LIKE '%j%'
GROUP BY name, surname
