<!--单表动态更新语句 -->
  <update id="update" parameterType="com.zzg.entity.ColumnValidate">
  		update ucas_bus_column_validate
  		<set>
			<if test="updateBy != null and updateBy != ''">
				  update_by = #updateBy,jdbcType=VARCHAR,
			</if>
      		<if test="state != null and state != ''">
        		`state` = #state,jdbcType=VARCHAR,
      		</if>
      		<if test="deleteFlag != null and deleteFlag != ''">
        		delete_flag = #deleteFlag,jdbcType=VARCHAR,
      		</if>
      		<if test="validateName != null and validateName != ''">
      			 validate_name =  #validateName,jdbcType=VARCHAR,
      		</if>
      		<if test="validateContent != null and validateContent != ''">
      			 validate_content = #validateContent,jdbcType=VARCHAR,
      		</if>
      		version = version + 1,
      		update_dt = now()
      	</set>
       	where sid = #sid,jdbcType=VARCHAR and version = #version, jdbcType=INTEGER
  </update>

重点代码：update_dt = now()
