動態 SQL 匹配查詢 AND OR

在接收前端傳入乙個關鍵字用來匹配資料庫的兩個欄位中的其中乙個的時候，mybatis 可以採用 and or 關鍵字進行查詢 。

and ( method like concat('%', #, '%')

or eventcode like concat('%', #, '%')
)	and statusofread = #
and bizcaseid = #

string statusofread = "0";       string method = "u";  

string bizcaseid = "10000000012028";      string key = "pa";

select * from tnotification where 

( method like concat('%', ?, '%') or 
eventcode like concat('%', ?, '%') 
) and statusofread = ? and bizcaseid = ? 
parameters: pa(string), pa(string), 0(string), 10000000012028(string)

select * from tnotific

and ( method like concat('%', #, '%')
or eventcode like concat('%', #, '%')
or eventname like concat('%', #, '%')
)	and statusofread = #
and bizcaseid = #

==>  preparing: 

select * from tnotific where ( method like concat('%', ?, '%') or eventcode like concat('%', ?, '%') or eventname like concat('%', ?, '%') ) and statusofread = ? and bizcaseid = ? 
==> parameters: pa(string), pa(string), pa(string), 0(string), 10000000012028(string)

select

p.id,
m.company
from operation_merchant_product p
inner join operation_merchant m on m.id = p.merchant_id
and m.merchant_name like concat('%',#,'%')
or m.merchant_code like concat('%',#,'%')
and p.status = 0
group by p.id
order by p.create_date desc
