i used your query.but my code execute upto a point i mentioned below.
Class.forName("com.mysql.jdbc.Driver");//Connection establishment to the database
i have a jlist binded with database.. in database i stored multiple items in single id.. it is displaying it as every item with that id..
i selected from a jlist mouse, printer, ups and stored it with a unique id..
in database it is showing like this
hardware quantity id
mouse 1 it request8696
printer 2 it request8696
switch 34 it request8696
now i have bind this db table with another jlist which showing only id's..
i want it to show it request8696 to b shown only once.. but it is showing 3 times..
i have used netbeans bind elements to bind jlist..
thank you in advance..
I am not too sure about netbeans binding properties, but there must be a property there where you are specifying a table name. Just see if you can specify a sql query instead of table name, if this works, try a query with distinct clause.
