JSP Question..Very Very Urgent....Please help....

Question

Hi...
I am working on customizing existing JSP Page. The idea is to retrieve the customer name as show in 1 and send is as run time parameter to SQL query and use the result of select statement to pass it to 2.
<INPUT TYPE="HIDDEN" NAME="soldtoCustPartyName" VALUE="<%= soldtoCustPartyName %>">.............1
The above line of code gives the customer name. We need to find the site id for the above customer and pass it to the following line of code. site id will replace the hardcoded number '7945'.
pageContext.setAttribute("party_site_id", new BigDecimal(7945), PageContext.REQUEST_SCOPE);...............2
Hence we create database connection to find out site id. The query will return the site id depending upon the customer name as in 1. SQL statement will be something like:
select site_id from ..... where fixed conditions and sitename = (from 1).
How can we create SQL statement to take run time values.
For eg. we do the following to execute Query after connecting to the databse..
Statement statement = connection.createStatement();
ResultSet rs = null;
rs = statement.executeQuery("SELECT party_id from apps.hz_party_sites where cust_name='IBM'");
<% rs.next(); %>
<% out.print(rs.getInt("party_id")); %>
How can the above query be modified to take run time value for cust_name.
THIS IS VERY VERY URGENT.....PLEASE HELP.......

Answer 1

Where are these run time values coming from? The user is entering the values into a form with that input?
If so, then the user will need to submit the form, you need a servlet to process the form, take the value from the parameter with the same name as the input, insert it into the SQL statement, and run the database query, get the results and store them in the context you want.
