<!– 删除多条，整形数组 –>
<delete id=”deleteArray” parameterType=”int”>
delete from person
where id in
(
<foreach collection=”array” item=”id” separator=”,”>
#{id}
</foreach>
)
</delete>
<!– 删除多条，LIST集合 –>
<delete id=”deleteList” parameterType=”int”>
delete from person
where id in
<foreach collection=”list” item=”id” open=”(” close=”)” separator=”,”>
#{id}
</foreach>
</delete>
<!– 删除多条,Map , ids 代表map中key –>
<delete id=”deleteMap” parameterType=”map”>
delete from person
where id in
<foreach collection=”ids” item=”id” open=”(” close=”)” separator=”,”>
#{id}
</foreach>
</delete>
