hi, i have this jsp page,

<input type="text" name="p_code" />
<input type="text" name="filterA" />
 <input type="text" name="ex_A" />

<input type="text" name="filterB" />
 <input type="text" name="ex_B" />

<input type="text" name="filterC" />
 <input type="text" name="ex_C" />

<input type="text" name="filterD" />
<input type="text" name="ex_D" />


<input type="submit" value="submit" />


and this is my DB schema,

P_code    Filter       Expired Date


And i wish to pump data into this table to make it like this,

P_code       Filter       Expired Date
A123          Filter A        12/2/2003
A123          Filter B        25/2/2003
.
.
.
.

How would be my sql statement? I only need the insert statement...

Thank You.

i assume you get form parameters in your servlet to variables:
   pCode
    fileterA, filterB, fileterC
    ex_a, ex_b, ex_c
with request.getParameter(), like this one:
...............
    pCode=request.getParameter("p_code);
...............
and then just 3 SQL statements to update your DB:
.........................
insert into yourtable (P_code, Filter, ExpiredDate) values (pCode, filterA, ex_a)
insert into yourtable (P_code, Filter, ExpiredDate) values (pCode, filterB, ex_b)
insert into yourtable (P_code, Filter, ExpiredDate) values (pCode, filterC, ex_c)
..............................

What dualsoul is saying will work perfectly but I would have done it like this...
<input type="text" name="p_code" />
<input type="text" name="filter" />
<input type="text" name="ex" />

<input type="text" name="filter" />
<input type="text" name="ex" />

<input type="text" name="filter" />
<input type="text" name="ex" />

<input type="text" name="filter" />
<input type="text" name="ex" />

Now in servlet
String[] filter=request.getParameterValues("filter");
String[] ex=request.getParameterValues("ex");
String p_code=request.getParameter("p_code');
for(int i=0; i<filter.length; i++)
insert into yourtable (P_code, Filter, ExpiredDate) values (p_code, filter[0], ex[0]);

This is less code and extensible to more than three inserts in the system..

Kuldeep ,
I have a doubt here , is the order of appreacnce of data on the form same as the way it appreas to the servlet
I mean if have

<input type="text" name="filter" value = "one"/>
<input type="text" name="filter" value = "two"/>

the at receiving end
filter[0] = one
filter[1] = two  ?

Thank you
