针对in字句中的数组使用方法
<select id="getCpProfileNamesByIds" resultType="string">
select name from mega_mis_smpp where id in
<foreach item="ids" index="index" collection="array" open="(" separator="," close=")">
#{ids}
</foreach>
</select>
针对in字句中的Collection使用方法
存储过程的使用:
<select id="FactoryNumberDao.getNewFactoryCode" resultMap="BaseResultMap" >
DECLARE @factoryCode varchar(5)
EXEC P_Factory_Number
@factoryCode = @factoryCode OUTPUT
SELECT @factoryCode as factoryCode
</select>
Ognl的使用:
<select id="AreaDao.findByPageArea.count"
resultType="java.lang.Long">
SELECT count(*) from gs_area
<include refid="areaDaoDynamicWhere"/>
</select>
<sql id="areaDaoDynamicWhere">
<!--
ognl访问静态方法的表达式
为@class@method(args),以下为调用框架中的Ognl.isNotEmpty()方法,还有其它方法如isNotBlank()可以使用,具体请查看Ognl类
-->
<where>
<!-- del_flag = '0' -->
<if test="@Ognl@isNotEmpty(areaCode)">
and area_code = #{areaCode}
</if>
<if test="@Ognl@isNotEmpty(areaName)">
and area_name like '%${areaName}%'
</if>
</where>
</sql>
sql标签:
<sql id="Base_Column_List" >
factory_code, factory_name, factory_user, factory_desc, tel, email, update_time,
state_flag
</sql>
<select id="FactoryDao.selectByPrimaryKey" resultMap="FactoryInfoMap" parameterType="java.lang.String" >
select
<include refid="Base_Column_List" />
from dbo.gs_factory
where factory_code = #{factoryCode,jdbcType=VARCHAR}
</select>
<select id="LineDao.findByPageLine.count"
resultType="java.lang.Long">
SELECT count(*) from gs_line
<include refid="lineDaoDynamicWhere"/>
</select>
<sql id="lineDaoDynamicWhere">

trim标签的使用:
<insert id="AssetTypeDao.insert" parameterType="com.easyway.eamsg.assetmgt.domain.AssetTypeInfo" >
insert into dbo.gs_asset_type
<trim prefix="(" suffix=")" suffixOverrides="," >
<if test="assetTypeCode != null" >

set标签的使用
<update id="AssetTypeDao.update" parameterType="com.easyway.eamsg.assetmgt.domain.AssetTypeInfo" >
update dbo.gs_asset_type
<set >

存储过程:
<select id="SiteAssetsSoftWareNumberDao.getNewsiteAssetsSoftwareCode" resultMap="BaseResultMap" parameterType="com.easyway.eamsg.assetmgt.domain.SiteAssetsSoftWareNumbeInfo" >
DECLARE @siteAssetsSoftwareCode varchar(13)
