ibatis動態sql標籤用法
1、動態sql片段
通過sql片段達到**復用
select count(*)
select *
from icp
name like '%$name$%'
path like '%path$%'
area_id = #area_id#
hided = #hided#
limit #_start#, #_size#
2、數字範圍查詢
所傳引數名稱是捏造所得，非資料庫字段，比如_img_size_ge、_img_size_lt欄位
img_size >= #_img_size_ge#
img_size < #_img_size_lt#
多次使用乙個引數也是允許的
execplantime >= #_now#
closeplantime <= #_now#
3、時間範圍查詢
createtime >= #_starttime#
and createtime < #_endtime#
4、in查詢
state in ('$_in_state$')
5、like查詢
(chnameone like '%$chnameone$%' or spellinitial like '%$chnameone$%')
chnametwo like '%$chnametwo$%'
6、or條件
(t.finished='11' or t.failure=3)
t.finished in ('10','19') and t.failure<3
7、where子查詢
code not in
(select t.contentcode
from cms_ccm_programcontent t
where t.contenttype='mznrlx_ma'
and t.programcode = #exprogramcode#)
select *
from cms_ccm_material
where code in
(select t.contentcode
from cms_ccm_programcontent t
where t.contenttype = 'mznrlx_ma'
and programcode = #value#)
order by updatetime desc
9、函式的使用
insert into rulemaster(
name,
createtime,
updatetime,
remark
) values (
#name#,
now(),
now(),
#remark#
select last_insert_id()
update rulemaster set
name = #name#,
updatetime = now(),
remark = #remark#
where id = #id#
10、map結果集
select count(a.*)
select a.id vid,
a.img imgurl,
a.img_s imgfile,
b.vfilename vfilename,
b.name name,
c.id sid,
c.url url,
c.filename filename,
c.status status
from secfiles c, juji b, videoinfo a
where
a.id = b. videoid
and b.id = c.segmentid
and c.status = 0
order by a.id asc,b.id asc,c.sortnum asc
limit #_start#, #_size#
