mybatis 批量增删改查操作的几种操作以及创建数据库索引

1、批量插入操作

---

     mapper.java层定义：

     int batchInsert(List stockList);

---

mapper.xml层的sql语句：

insert into t_stock (status, asset_classify_id,asset_id,asset_item_id, name,num, batch_num, tag_id,rfid, epc, barcode,qr_code, erp, unit,pic_url, specification, model,material, color,length,width, height, weight,density, volume, price01,price02,warehouse_id, storage_zone_id,storage_location_id,storage_location_tag_id,remark, attr01, attr02,attr03, create_date,last_update,creater, client_id)values (#{item.status,jdbcType=VARCHAR},#{item.assetClassifyId,jdbcType=BIGINT},#{item.assetId,jdbcType=BIGINT}, #{item.assetItemId,jdbcType=BIGINT},#{item.name,jdbcType=VARCHAR},#{item.num,jdbcType=VARCHAR},#{item.batchNum,jdbcType=VARCHAR}, #{item.tagId,jdbcType=VARCHAR},#{item.rfid,jdbcType=VARCHAR}, #{item.epc,jdbcType=VARCHAR},#{item.barcode,jdbcType=VARCHAR},#{item.qrCode,jdbcType=VARCHAR},#{item.erp,jdbcType=VARCHAR}, #{item.unit,jdbcType=VARCHAR},#{item.picUrl,jdbcType=VARCHAR},#{item.specification,jdbcType=VARCHAR},#{item.model,jdbcType=VARCHAR},#{item.material,jdbcType=VARCHAR},#{item.color,jdbcType=VARCHAR}, #{item.length,jdbcType=DECIMAL},#{item.width,jdbcType=DECIMAL}, #{item.height,jdbcType=DECIMAL},#{item.weight,jdbcType=DECIMAL},#{item.density,jdbcType=DECIMAL},#{item.volume,jdbcType=DECIMAL}, #{item.price01,jdbcType=DECIMAL},#{item.price02,jdbcType=DECIMAL},#{item.warehouseId,jdbcType=BIGINT},#{item.storageZoneId,jdbcType=BIGINT},#{item.storageLocationId,jdbcType=BIGINT},#{item.storageLocationTagId,jdbcType=BIGINT},#{item.remark,jdbcType=VARCHAR}, #{item.attr01,jdbcType=VARCHAR},#{item.attr02,jdbcType=VARCHAR},#{item.attr03,jdbcType=VARCHAR},#{item.createDate,jdbcType=TIMESTAMP},#{item.lastUpdate,jdbcType=TIMESTAMP},#{item.creater,jdbcType=BIGINT}, #{item.clientId,jdbcType=BIGINT})
