searching from database on jsp

Question

Hello I am writing a code where people can search activities from database by using jsp. When I execute the program, I can search according to type,description,location,city successfully. I can see datas on page. But when I select date option like tomorrow or etc it returns empty table. Where is the problem in my code ? What will be the correct code ? (PS all attributes are varchar except id)

If I fill type as 'Music' I am etting this table search.jsp

It seems the date is stored in time stamp format and while retrivinng, you provide your search query as only yyyy-mm-dd format. Put the exact time stamp as yyyy-mm-dd:ss format and check whether the result is returned or not. — LONGHORN007, Jan 02 '17 at 11:45
You really should read [about servlets](http://stackoverflow.com/q/2095397/4391450) because this is a bad design (an a painful to see ;) )to have that much scriplet in a jsp file. EDIT : Have you tried your query (the one build in the jsp) ? — AxelH, Jan 02 '17 at 11:46

Here is your select

<select name='time'>
    <option value='1'>Today</option>
    <option value='2'>Tomorrow</option>
    <option value='3'>This Week</option>
    <option value='4'>This Weekend</option>
    <option value='5'>Next Week</option>
    <option value='6'>Next Weekend</option>
    </option>
</select>

In the JSP, your receive the value. Not a date but a numeric value (in a String).

You should evaluate the date you want based on this numeric value. Using a switch and Calendar to add the value to the current date. But you also have ranges of dates here with Week-end or Week.

Plus, I see date and time in your query, but only time in the form. You should check those.

PS : I didn't mention the possibility to update the value because Assen wrote it in the same time. This is true too. — AxelH, Jan 02 '17 at 12:03

If you use option like this it will work:

<select name='time'>
    <option value='2017-01-02'>Today</option>
    <option value='2017-01-03'>Tommorow</option>
    </option>
</select>
