MYSQL AND OR条件问题


SELECT id,name		
FROM test 
WHERE type_1 = 1 OR type_2 = 1 AND id = 1

这样会印出全部，无视了id=1这个条件，要怎么改才对呢?
------解决思路----------------------

SELECT id,name       
FROM test 
WHERE (type_1 = 1 OR type_2 = 1) AND id = 1

SELECT id,name       
FROM test 
WHERE type_1 = 1 OR (type_2 = 1 AND id = 1)

SELECT id,name       
FROM test 
WHERE (type_1 = 1 OR type_2 = 1) AND id = 1

要看你的实际需要
