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
要看你的实际需要
