**注意:**以下條件構造器的方法入參中的column
均表示資料庫字段
@test
public
void
testdelete()
sql:update user set deleted=1 where deleted=0 and name is null and age >= ? and email is not null
**注意:**seletone返回的是一條實體記錄,當出現多條時會報錯
@test
public
void
testselectone()
select id,name,age,email,create_time,update_time,deleted,version from user where deleted=0 and name = ?
包含大小邊界
@test
public
void
testselectcount()
select count(1) from user where deleted=0 and age between ? and ?
@test
public
void
testselectlist()
select id,name,age,email,create_time,update_time,deleted,version
from user where deleted=0 and name = ? and id = ? and age = ?
selectmaps返回map集合列表
@test
public
void
testselectmaps()
select id,name,age,email,create_time,update_time,deleted,version
from user where deleted=0 and name not like ? and email like ?
in、notin:
notin
("age",)
--->age not in (1,
2,3)
notin
("age",1
,2,3
)--->age not in (1,
2,3)
insql、notinsql:可以實現子查詢
@test
public
void
testselectobjs()
select id,name,age,email,create_time,update_time,deleted,version
from user where deleted=0 and id in (select id from user where id < 3)
不呼叫or
則預設為使用and
連
@test
public
void
testupdate1()
update user set name=?, age=?, update_time=? where deleted=0 and name like ? or age between ? and ?
這裡使用了lambda表示式,or中的表示式最後翻譯成sql時會被加上圓括號
@test
public
void
testupdate2()
update user set name=?, age=?, update_time=?
where deleted=0 and name like ?
or ( name = ? and age <> ? )
@test
public
void
testselectlistorderby()
select id,name,age,email,create_time,update_time,deleted,version
from user where deleted=0 order by id desc
直接拼接到 sql 的最後
**注意:**只能呼叫一次,多次呼叫以最後一次為準 有sql注入的風險,請謹慎使用
@test
public
void
testselectlistlast()
select id,name,age,email,create_time,update_time,deleted,version
from user where deleted=0 limit 1
@test
public
void
testselectlistcolumn()
select id,name,age from user where deleted=0
@test
public
void
testupdateset()
();
user.setage(99);
//修改條件
.like("name", "h")
.set("name", "老李頭")//除了可以查詢還可以使用set設定修改的字段
.setsql(" email = '[email protected]'");//可以有子查詢
update user set age=?, update_time=?, name=?, email = '[email protected]' where deleted=0 and name like ?
