按期查询sql查询

Question

我的表中有两个字段，NEXTTIME和ENDTIME，表名是VISIT。

我会从我的页面得到一个值，即00:05:00或者那样。最少5分钟。我将不得不根据该值从数据库中进行查询。

我会得到最早的NEXTTIME和那个时间+ 00:05:00。

比方说，最近的NEXTTIME是06:44。

我的查询会像06:45，06:50，等等..

我也会有另一个输入值是间隔时间。

Nvm that。

我只是想知道如何获得间隔查询。

结果会看起来像这样。

NEXTTIME：ENDTIME

6时55分00秒〜6点58分零零秒

7时25分00秒〜7点28分00秒

7时35分〇〇秒〜08 ：52：00

八点38分00秒〜8时48分00秒

8点40分零零秒〜8时54分零零秒

8点43分00秒〜9时36分00秒

九时12分00秒〜09:30:00

这是基于我提议提供的信息，我对你的问题的理解解决方案。为了符合图表周期，只更改每个联合查询的select语句和where子句中的句点。
