mybatis直接运行sql

List<LinkedHashMap<String, Object>> selectByYear(String sql);

int insert(String sql);

int update(String sql);

int delete(String sql);

<select id="selectByYear" parameterType="java.lang.String" resultType="java.util.LinkedHashMap">
  ${value}
</select>
<insert id="insert" parameterType="java.lang.String">
    ${value}
</insert>
<update id="update" parameterType="java.lang.String">
  ${value}
</update>
<delete id="delete" parameterType="java.lang.String">
  ${value}
</delete>
