mybatis or

這兩天項目用到mybatis，碰到and or的聯合查詢，語句像這樣的

select * from table where xxx = "xxx" and (xx1="xx1" or xx2="xx2")

但是我發現mybatis，暫時沒有這種寫法，於是我變相的這樣實現

select * from table where (xxx = "xxx" and xx1="xx1") or (xxx="xxx" and xx2="xx2")

 

例子:

WeixinQrcodeExample e = new WeixinQrcodeExample();
                Criteria c1=e.createCriteria();
                c1.andAccountidEqualTo(accountId);
                if(StringUtil.isNotEmpty(name)){
                    c1.andQrcodeTitleLike("%"+name+"%");
                }
                c1.andActionNameEqualTo(WeixinConstant.QrcodeType.QR_LIMIT_SCENE);
                Criteria c2=e.createCriteria();
                c2.andAccountidEqualTo(accountId);                
                c2.andExpireTimeLessThanOrEqualTo(new Date().getTime());
                if(StringUtil.isNotEmpty(name)){
                    c2.andQrcodeTitleLike("%"+name+"%");
                }
                e.or(c2);

 

最后的映射的sql如下:

SELECT *  FROM weixin_qrcodes WHERE (accountid = ? AND qrcode_title LIKE ? AND action_name = ?) OR (accountid = ? AND expire_time <= ? AND qrcode_title LIKE ?)
