批量插入，主键冲突就更新

<insert id="insertFpxxBatch" parameterType="java.util.List">
<![CDATA[
insert into BM_FPXX (
fpzl,fphm,gfmc,gfsh....
)
values
]]>
<foreach collection="list" item="item" separator=",">
<![CDATA[
(#{item.fpzl,jdbcType=VARCHAR},#{item.fphm,jdbcType=VARCHAR},SYSDATE(),SYSDATE()。。。。)
]]>
</foreach>
on duplicate key update 
fpzl=VALUES(fpzl),fphm=VALUES(fphm),gfmc=VALUES(gfmc),
update_time=current_timestamp
</insert>

　　

自增主键插入

<insert id="insertRole" parameterType="com.holytax.common.data.role.entity.Role">
<selectKey resultType="java.lang.Long" keyProperty="id">
SELECT LAST_INSERT_ID() as id
</selectKey>
INSERT INTO bm_role
<trim prefix="(" suffix=")" suffixOverrides=",">
<if test="roleName != null">
ROLE_NAME,
</if>
<if test="description != null">
DESCRIPTION,
</if>
<if test="status != null">
STATUS,
</if>
<if test="createTime != null">
CREATE_TIME,
</if>
</trim>
<trim prefix="values (" suffix=")" suffixOverrides=",">
<if test="roleName != null">
#{roleName,jdbcType=VARCHAR},
</if>
<if test="description != null">
#{description,jdbcType=VARCHAR},
</if>
<if test="status != null">
#{status,jdbcType=CHAR},
</if>
<if test="createTime != null">
#{createTime,jdbcType=TIMESTAMP},
</if>
</trim>
</insert>

　

<!-- 分页查询数据头文件 把头和尾加到正常sql语句上-->
<sql id="queryHeader">

日期操作
<if test="kprqBegin != null">
and DATE_FORMAT(kprq, ‘%Y-%m-%d‘) &gt;= DATE_FORMAT(#{kprqBegin}, ‘%Y-%m-%d‘)
</if>
<if test="kprqEnd != null">
and DATE_FORMAT(kprq, ‘%Y-%m-%d‘) &lt;= DATE_FORMAT(#{kprqEnd}, ‘%Y-%m-%d‘)
</if>
order by str_to_date(kprq, ‘%Y-%m-%d‘) desc
