前言：用mybatis也好几年了，mybatis在批量的增删操作也写起来也是比较简单的，只有批量更新这一块是特别坑，特此记录。
注：本文主要用来记录oracle和mysql数据库在使用mybatis的情况下批量增、删、改（更新）的常用写法
一、批量插入
1、oracle写法：
<insert id="insertZaixcsList" parameterType="cc.eguid.Zaixcs"> insert into b_dbgl_zaixcs ( zaixcsid, mingc, pingsyid, xinxid, fujid, jieg, pingfjg, pingf, zhuangt, shic, startriq, endriq, pingfriq, datr, pingfr, beiz ) <foreach collection="list" item="item" index="index" separator="union all"> (select #{item.zaixcsid,jdbcType=VARCHAR}, #{item.mingc,jdbcType=VARCHAR}, #{item.pingsyid,jdbcType=VARCHAR},#{item.xinxid,jdbcType=VARCHAR}, #{item.fujid,jdbcType=VARCHAR}, #{item.jieg,jdbcType=VARCHAR}, #{item.pingfjg,jdbcType=VARCHAR}, #{item.pingf,jdbcType=DECIMAL}, #{item.zhuangt,jdbcType=VARCHAR},#{item.shic,jdbcType=DECIMAL}, #{item.startriq,jdbcType=TIMESTAMP}, #{item.endriq,jdbcType=TIMESTAMP}, #{item.pingfriq,jdbcType=TIMESTAMP}, #{item.datr,jdbcType=VARCHAR}, #{item.pingfr,jdbcType=VARCHAR},#{item.beiz,jdbcType=VARCHAR} from dual) </foreach> </insert>
2、mysql写法：
insert into B_SYS_FUJ (FUJ_ID, RELATE_ID, RELATE_TABLE_NAME, FUJ_LX, WENJLX,WENJM, FJMC, FUJ_PATH,CREATE_USER_ID, CREATE_USER, CREATE_TIME, RELATE_TABLE_ZIDUAN,CONTENTTYPE,ZHUANGT) values <foreach collection="list" item="item" index="index" separator="," > (#{item.fujId,jdbcType=VARCHAR}, #{item.relateId,jdbcType=VARCHAR}, #{item.relateTableName,jdbcType=VARCHAR}, #{item.fujLx,jdbcType=VARCHAR}, #{item.wenjlx,jdbcType=VARCHAR}, #{item.wenjm,jdbcType=VARCHAR}, #{item.fjmc,jdbcType=VARCHAR}, #{item.fujPath,jdbcType=VARCHAR}, #{item.createUserId,jdbcType=VARCHAR}, #{item.createUser,jdbcType=VARCHAR}, #{item.createTime,jdbcType=TIMESTAMP}, #{item.relateTableZiduan,jdbcType=VARCHAR}, #{item.contentType,jdbcType=VARCHAR}, #{item.zhuangt,jdbcType=VARCHAR} ) </foreach>
二、批量删除
注：批量删除操作oracle与mysql写法相同
当collection=”array“时,表名参数为数组；
当collection=”list“时,表名参数为集合；
1、删除数组数组
<delete id="batchDeleteEmpArr" parameterType="int"> delete from emp where empno in <foreach item="empnoItem" collection="array" open="(" separator="," close=")"> #{empnoItem} </foreach> </delete>
2、删除list列表数据
<delete id="batchDeleteEmpList" parameterType="int"> delete from emp where empno in <foreach item="item" collection="list" open="(" separator="," close=")"> #{item} </foreach> </delete>
3、删除查询到的数据
<delete id="deleteByParent" parameterType="string"> delete from QIYDFBZ where BIAOZBID in( SELECT biaozbid FROM B_DBGL_QIYDFBZ CONNECT BY PRIOR FENXID = FUJID start WITH BIAOZBID = #{biaozbid,jdbcType=VARCHAR} ) </delete>
三、批量更新
1、oracle写法：
注：这样的写法虽然可以更新，但是更新操作返回值是-1，并没有返回更新的行数
<update id="updateBatch" parameterType="com.itssky.aqjg.entity.dbgl.Zaixcs"> begin <foreach collection="list" item="item" index="index" separator=";"> update B_DBGL_ZAIXCS <trim prefix="set" suffixOverrides=","> <if test="item.mingc != null and item.mingc !=''"> MINGC= #{item.mingc,jdbcType=VARCHAR}, </if> <if test="item.pingf != null and item.pingf !=''"> PINGF=#{item.pingf,jdbcType=DECIMAL}, </if> <if test="item.zhuangt != null and item.zhuangt !=''"> ZHUANGT=#{item.zhuangt,jdbcType=VARCHAR}, </if> <if test="item.shic != null and item.shic !=''"> SHIC=#{item.shic,jdbcType=DECIMAL}, </if> <if test="item.startriq != null and item.startriq !=''"> STARTRIQ=#{item.startriq,jdbcType=TIMESTAMP}, </if> </trim> where ZAIXCSID = #{item.zaixcsid,jdbcType=VARCHAR} </foreach> ;end; </update>
2、mysql写法：
注：mysql数据库连接需要加上&allowMultiQueries=true 例如：jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true <update id="batchUpdate" parameterType="java.util.List"> <foreach collection="list" item="item" index="index" open="" close="" separator=";"> update ZAIXCS <trim prefix="set" suffixOverrides=","> <if test="item.mingc != null and item.mingc !=''"> MINGC= #{item.mingc,jdbcType=VARCHAR}, </if> <if test="item.shic != null and item.shic !=''"> SHIC=#{item.shic,jdbcType=DECIMAL}, </if> <if test="item.startriq != null and item.startriq !=''"> STARTRIQ=#{item.startriq,jdbcType=TIMESTAMP}, </if> <if test="item.beiz != null and item.beiz !=''"> BEIZ=#{item.beiz,jdbcType=VARCHAR}, </if> </trim> where ZAIXCSID = #{item.zaixcsid,jdbcType=VARCHAR} </foreach> </update>
