批量查询

 <select id="getPreIds" resultType="java.lang.String"parameterType="java.util.List">SELECT  pre_batch_id  FROM public.mine_data_quality_check_record  WHERE deleted=0<if test="list != null">AND pre_batch_id in (<foreach collection="list" item="id" separator=",">#{id}</foreach>)</if>GROUP BY pre_batch_id HAVING count(*)>2 ORDER BY pre_batch_id ASC</select>
