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?

回复讨论(解决方案)

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
