表格分页数据对象

mapper.xml
<sql id="selectRoleVo"> 连表查询的sql语句,写一遍就不用在单独写了 </sql>
列表展示和列表查询展示角色信息的sql
<select id="selectRoleList" parameterType="SysRole" resultMap="SysRoleResult">
<include refid="selectRoleVo"/>
where r.del_flag='0'
<if test="roleName !=null and roleName!=''">
and r.role_name like concat('%',#{roleName},'%')
</if>
<if test="beginTime !=null and beginTime !=''">
and r.create_time >= TO_DATE(#{beginTime},'YYYY-MM-DD HH24-MI-SS')
</if>
</select>
统一性修改角色信息表的sql
<update id="updateRole" parameterType="SysRole">
update sys_role
<set>
<if test="roleName!=null and roleName!=''">role_name=#{roleName},</if>
<if test="status!=null and status!=''">status=#{status},</if>
update_time= now() 或者是 current_timestamp
</set>
where role_id=#{roleId}
</update>
批量删除角色信息的sql
<delete id="deleteRoleByIds" parameterType="String">
update sys_role set del_flag = '2' where role_id in
<foreach collection="array" item="roleId" open="(" separator="," close=")">
#{roleId}
</foreach>
</delete>
增加角色信息的统一性sql
<insert id="insertRole" parameterType="SysRole">
insert into sys_role(
<if test="roleId!=null and roleId!=''">role_id,</if>
<if test="roleName!=null and roleName!=''">role_name,</if>
create_time
) values(
<if test="roleId!=null and roleId!=''">#{roleId},</if>
<if test="roleName!=null and roleName!=''">#{roleName},</if>
current_timestamp
)
</insert>
后台管理增删查改统一性代码--若依前后端分离版本
