Mybatis批量插入Oracle数据库

批量新增时有序列的用法：

	<insert id="insertList" parameterType="java.util.List"  useGeneratedKeys="false">
        INSERT INTO T_JR
            (
            TN_GZZFZBID,
            TN_GZZSZBID,
            TN_LX,
            TC_BM,
            TC_MC
            )
            select SEQ_JR.NEXTVAL,tnGzzszbid,tnLx,tc_dwbm,tc_dwmc
            from(
        <foreach collection="list" item="item" index="index"
            separator="union all">
                select tc_dwbm,tc_dwmc,#{item.tnGzzszbid} as tnGzzszbid,#{item.tnLx} as tnLx
                from t_jcsj_gndws
	 	        where tc_sjdwbm=#{item.tcBm,jdbcType=VARCHAR}
        </foreach>
         )
    </insert>

没有序列时：

	<insert id="insertList" parameterType="java.util.List">
		INSERT ALL
		<foreach collection="list" item="item" index="index"
			separator="">
			INTO T_JR
			( 
			TN_GZZSZBID,
			TN_LX,
			TC_BM,
			TC_MC)
			VALUES
			(
			#{item.tnGzzszbid,jdbcType=DECIMAL},
			#{item.tnLx,jdbcType=DECIMAL},
			#{item.tcBm,jdbcType=VARCHAR},
			#{item.tcMc,jdbcType=VARCHAR}
			)
		</foreach>
		select 1 from dual
	</insert>
