1.批量删除
@Delete({"<script>",
"delete from li_print_goods_connection where printer_id = #{printerId} and goods_id in ",
"<foreach collection='list' item='goodsId' open='(' separator=',' close=')'>",
"#{goodsId}",
"</foreach>",
"</script>"})
Integer deletePrinterBindAll(String printerId, List<String> list);
2.批量查询
@Select({"<script>" +
"select goods_name,id from li_goods where id in " +
"<foreach item='goodsId' index='index' collection='list' open='(' separator=',' close=')'>" +
"#{goodsId}",
"</foreach>",
"</script>"})
List<Goods> getGoodsList(List<String> goodsIds);
同理,更新、插入只需要将注解更换为update和insert即可。
注意:
-
参数如果没有@Param指定,collection的值为list,不能为其他,用单引号即可,不用#{}包含
-
item是循环集合中的单个值引用,与<foreach></foreach>标签内的值对应,标签内的参数需要用#{}包含
