where (条件1)and (条件2 or 条件3 or 条件4)
= where (条件1 and 条件2)or (条件1 and 条件3) or (条件1 and 条件4)
结果 是这样的
WHERE ( birthdate between ? and ? and username like ? ) or( birthdate between ? and ? and email like ? ) or( birthdate between ? and ? and phone like ? )
1. 在Example中每一个criteria相当于一个括号,把里面的内容当作一个整体。
Where(userid=’1’ and name=’2’)
1

UserExample example = new UserExample();
UserExample.Criteria c1 = example.createCriteria();
C1.andUseridEqualTo(“ 1 ”);
C2.andNameEqualTo(“ 2 ”);
|
C1.andUseridEqualTo(“
1
”)
.andNameEqualTo(“
2
”);也可
2. 在criteria中没有直接的or。
(1) where(A and B) or (C and D)

BasePointsExample.Criteria criteria1 = example.createCriteria();

criteria2.andUsernameEqualTo( ‘33‘ );
criteria2.andPointcontentLike(StringUtil.concatlike( ‘44‘ ));
