MySQL从两个表中选择语句

Question

I have two tables:

Users:

id        name       isSpecial
1         Tal        1
2         Jorden     0
3         John       1
4         Paige      0

Details:

id        userId       Country       zipCode
1         1            Israel        4564
2         3            US            554654

I want to get all the data from Users by the name of Jorden OR if isSpecial is 1 to be shown like this

Result:

id        name         Country       zipCode
1         Tal          Israel        4564
2         Jorden       
3         John         US            554654

I know its supposed to be a simple query but I cant get the results that I want! Can anyone help me?

Answer 1

You can use a LEFT JOIN :

SELECT
  u.id,
  u.name,
  u.isSpecial,
  d.country,
  d.zipCode
FROM Users u
LEFT JOIN Detals d
ON u.id = d.userId
WHERE u.name = 'Jorden'
  OR u.isSpecial = 1

Answer 2

Like this

SELECT u.id,u.name,d.country,d.zipCode FROM
Users u 
LEFT outer JOIN Details d
ON u.id = d.userId
WHERE u.name = 'Jorden' OR u.isSpecial = '1'

Answer 3

Left join would serve your purpose.

SELECT uObj.ID,uObj.Name,DObj.country, DObj.zipcode FROM users uObj LEFT JOIN Details DObj ON uObj.ID=DObj.userID WHERE uObj.name = 'Jorden' OR uObj.isSpecial = 1;
